Sky Captain and the World of Tomorrow ray gun replica by Maggie McFee

So let me just get this confession out of the way.

I love Kerry Conran’s Sky Captain and the World of Tomorrow. I love it to death, warts and all. Roger Ebert said of the film, “It’s like a film that escaped from the imagination directly onto the screen, without having to pass through reality along the way.”

Well, the imagination in question could have been mine, if it hadn’t been Kerry and Kevin Conran’s. It speaks to me on a very deep level; It’s a film that could have been made just for me. I’m not old enough to remember film and radio serials, obviously, but I did grow up on a steady diet of SciFi — Doctor Who and Star Trek being staples of my diet and, of course, Star Wars — and that diet sometimes included old serials which played on a local TV station late at night as filler for the late night movie. I recall many a night sneaking out of bed to watch Flash Gordon or some other B&W treat quietly in the living room while my parents slept. Hey, they advertised them during the afternoon when I was watching cartoons, how could I resist? Later in life I developed a fascination with old radio serials as well and listened to countless hours of them.

Sky Captain was like a concentrated booster shot of all that: Giant robots, heroes in tricked out aircraft, swaggering female fighter aces, flying aircraft carriers… and ray guns. Sky Captain was a siren call to me in 2004. And there’s one prop from the film I’ve always wanted, in some form or other, but never have found: Dex’s ray gun. Sure, I have the ornament version, but that’s small consolation. Literally. So I decided it was time to make my own and got to modeling. I’ve printed a couple (you can see one here, but bear in mind this is a rough version) to test and hand fit and I’m still tweaking, but it’s about 95% done, I think. I’ve extended the nose cone a bit since I took this screen shot, but this is how the current model looks.


More soon as I’ll be building and painting a clean final version soon.

Prototyping and Printing

// May 21st, 2016 // No Comments » // art, props

I finally broke down and bought a grown-up 3D printer. My Prusa i3 was fine, as far as it went, but my growing envy of the nice (and giant) prints of Lulzbot TAZ 5 owners’s like James Bruton did me in. So I bought a Lulzbot TAZ 5 and added a FlexyDually dual extruder which allows me to print in normal materials from the primary head as well as flexible (such as Ninjaflex) and support materials from a second head. And I don’t regret it one bit. This machine is heaven. It’s like going from a motorcycle to a luxury car.

Speaking of printing, I’ve been designing/prototyping some props. More on all these later, but here’s a peek at what’s on deck at the moment.

commlock1The first is a scratch-built Commlock (another Space: 1999 prop). I’m calling it a prototype in that the idea was to figure out how to build one well by building one at all. :) I have a screen and electronics for the next iteration using what I learned. This one, as will the next, was built from Plastruct sheets and tubing, some laser cut elements, 3D printed buttons with white-on-black label tape for the numbers.

Related, I just bought a Century Casting commlock off eBay, so I’ll build that later as well. But the scratch-builts are my first priority.




I’ve also been working on 3D modeling the Vulcan 65 grenade from the first Hellboy movie. I have a few additions to make on the internals and just finished making the top removable, but I’ve pretty happy with the overall design. I’ll make a couple more and then I may make a cast of it so I can make some resin versions. I plan to add LEDs to one or two of the later printed ones.

The lettering is done using waterslide decals I designed and printed in Photoshop.





saltcellar_proto2Yet another Hellboy prop I’m working on is Ilsa’s salt cellar, the one containing the tears of a thousand angels (or martyrs in the earlier script). This one has been all about modeling and learning to make a patina’d surface look right. I solid-modeled the base, legs and dome. The glass is just a 7″ glass vase. It’s not exactly the right size. It’s 7″ high and about 3.2″ wide, should be more like 4″ wide, I think. I’m currently looking for a better one (or two… or twelve). Adam Savage actually owns the original and once put up a bunch of hi-rez photos on The RPF, but they’re no longer there. So I’m working on the [missing] dome art using screen grabs from the movie. I have to sort out how to do the knurling on the edges since that’s difficult to print.



eyetestproto Speaking of Adam Savage, I’m also working on a replica of a prop he was originally involved in designing and building. In Bicentennial Man, there’s a very neat little art deco eye examination device. It’s all black and brass and it’s terribly, terribly interesting. I started modeling it a while ago and printed a test to make sure it all fit together. It didn’t. But I sanded it down and slapped some paint on it just to see how it looked. It looked like someone painted it quickly is what it looked like. hehe Anywho, I’ve added the splines on the sides and adjusted the center piece so the next one should fit together better. Once I’ve got it looking right I’ll print another, add the LEDS and do a proper paint on it. Maybe I’ll also send one to Adam… ;)

And then I’d like to build a HUD Motion Tracker from Aliens… but that’s for another day.

Afternoon diorama build for NECA Alien figures

// April 14th, 2016 // Comments Off on Afternoon diorama build for NECA Alien figures // props

The original Alien movie is still one of my favorite films. Like it’s sibling Blade Runner, also one of my all-time favorites, I’ve no idea how many times I’ve seen it. Let’s just go with “A lot.”

I recently bought some of NECA’s fantastic Alien and Aliens figures, so I decided I wanted to build dioramas for at least two scenes, maybe three. For sure I wanted to build one of Ripley and the ‘Big Chap’ xenomorph in a Nostromo corridor. Another I plan to do is an airlock scene with [all space-suited] Dallas, an Amanda Ripley figure standing in for Lambert, and Kane with melted visor and facehugger. I’m also considering a Narcissus shuttle scene with Ripley in the white ‘compression suit’ and a Big Chap, but I’m not sure if I’ll get up the nerve to tackle that as it’s a bit more complex. I also have the NECA Powerloader, so… who knows what could happen with that one day!

Here’s the first diorama, Ripley (and Jones!) and Big Chap in a corridor of the Nostromo. The overall structure is made of white and black foamcore glued to a hardboard base. The pipes, slats and straight bits are Plastruct styrene elements. The floor is Plastruct terracotta roof sheet sprayed black. The other bits (mostly hidden behind the xenomorph in the photos, unfortunately) are kit-bashed from sprues, the Tamiya Flakvierling 38 kit and I think a couple of things from a AMT Saturn V kit.




Space: 1999 22″ Eagle build

// April 14th, 2016 // Comments Off on Space: 1999 22″ Eagle build // props

Recently Round2 released the model I’ve been waiting most of my life for: A 22″ Eagle Transporter from Space:1999. I can’t adequately express my love for this [fictional] spacecraft design. It is simply brilliant and utterly believable. It’s practical and beautiful in its utilitarianism. The show itself hasn’t aged well, but the design of this wonderful craft certainly has. So. I had to build one… maybe two. As I told my friend John [Foster, also an Eagle enthusiast], I have an Eagle Rule; When any new Eagle model is released, all other projects hit the backburner.

In the past, I’ve built one each of the old (and just ‘adequate’) MPC and AMT 11″ kits. This was some time ago and I don’t have either any more. But since then I’ve built a Warp Models kit (resin kit with lots of white metal parts including an all-metal spine) and the Round2 Deluxe re-issue of the MPC kit with lab pod and booster.

But the 22″ is the one I’ve been waiting on… for years. And not only did Round2 produce a 22″ Eagle kit, they also offered an upgrade kit with metal engine bells and another kit with metal attitude thrusters. Being the lover of this fictional spacecraft that I am, I went for the upgrades along with the kit. In fact… I ended up buying two sets of all. One day I’ll build another 22″ with, maybe, a rescue pod. (I recommend visiting CultTVMan if you’d like to buy your own)

OK. Apart from being bigger, what’s the deal with this whole 22″ thing? During the original production of Space: 1999 three scales of Eagle Transporters were built. 44-inches, 22-inches and roughly 11-inches (OK, and a 5-inch version, but… no one ever talks about that one). I don’t expect I’ll ever build or acquire a 44″ Eagle, but I’m quite happy with the 22″ version. I also built a 1:48 scale buggy to go with it as I did for my 1:72 Warp Models Eagle (shown below for size comparison).

So without further ado, my 22″ Eagle Transporter (I may post some ‘in progress’ pics later):







Hellboy Samaritan replica

// February 22nd, 2016 // 1 Comment » // props

Screen Shot 2016-02-21 at 11.25.58 PM

I probably implied I was then going back to work on the 22″ Round 2 Space 1999 Eagle Transporter I’ve been tweeting about, but… I couldn’t resist. I really do lament not having a Samaritan (aka Good Samaritan) in my collection and constantly kick myself for not having bought one of the Sideshow Collectibles replicas back when they came out. So I downloaded one of the better 3D models out there (thanks danonator and JerseyBeast) and, after tweaking the top strap/breach (I know, it’s a revolver, but it has a breach in the top strap) and some scaling I started printing it to put together later.

And then I couldn’t help myself. The print came out so nice. And my re-modeled breach made me happy and… This happened over the course of yesterday and today
(Update: The stand in the first pic is a new addition. I designed and printed the 2 arms, nameplate, and ammo holder, then painted them to look like old cast bronze. I stained and weathered the wooden box, printed the BPRD logo from the original hilt again and put that all together. I also printed some of d3delta3d’s ammo.)

IMG_20160221_231341 IMG_20160221_231449 IMG_20160221_231359 IMG_20160221_231325



I sanded the print, but I didn’t really go out of my way to hide that it’s 3D-printed. That’s probably most evident on the cylinder and grip. But I did sand, rub down with acetone and then paint the parts with a hammered metal spray. That was topped with some flat clear coat. Then I weathered it with silver (plus rub down with my filthy paint-covered fingers).

The hammer and trigger were painted with metallic shimmer and then dusted with flat black. The pin and one of the screws were done in copper and then smudged to flatten.

The grip is acrylic paint starting with a dark brown, some watered-down tan on top of that, then black wipes with a brush and later a wide-cell sponge to create the grain. Several coats of clear gloss and it was a fair approximation of the real thing (although the grip isn’t on-model at the crown, but it’s close enough). I added the BPRD medallion, which was painted silver, then weathered with black acrylic and wiped down to a dull iron look.

The ring in the butt (stop laughing) is a piece of jewelry, a captive bead ring, dulled and squeezed into a circle. Then I tied a piece of leather cord to it (after dipping into some coffee to stain it – yes, I was drinking coffee at 10pm, because I’m an adult and I can do what I want.)

And there you have it. A ‘pretty close’ replica of Hellboy’s [Good] Samaritan. I feel better now. Well, I will be after I print some shells for it and a stand. Then, I swear I’ll get back to the Eagle!

But first… maybe I’ll fix the scale and print another that I can make more accurate. For later, I mean. Really!

Cult of Cthulhu box

// February 14th, 2016 // Comments Off on Cult of Cthulhu box // art, props

This was a weekend build (but more like two evenings) of a prototype for an idea I had earlier in the week; A box for Cthulhu cultists to hold sacred artifacts.  I’m happy with how it turned out, however I think the next version will be a pocket box which pulls out of the top of the standing outer box. I’ll probably add a handle to the top of this one as, after looking at the pics, it seems appropriate (and what gave me the idea to make it a pocket box next time.)

This is made using an off-the-shelf wooden craft store box with the catch removed. It’s covered in a synthetic hide which I bought off Amazon a while ago. The legs, corners, domed tacks and fake lock mechanism are scrap-booking ornaments bought at Michaels (mostly Jim Holtz brand). They’re sprayed with Dark Bronze hammered-finish paint (except the lock which I decided I’d paint as thought it were iron and rusty) and them weathered with Testor’s gold, Alclad ‘Burnt Iron’, and dulling spray. The interior has a felt bottom and Damask wallpaper in the upper lid. The wood is darkened and aged with a combination of brown acrylic paint and an india ink wash. Spritzes of flat black paint and dulling sprays over everything knock down any remaining shine. A smudged bloody thumb print also seemed appropriate. :)

The Cthulhu sigil is 3D-printed using a model from Thingiverse designed by Al Billings. It was sanded, painted with black hammered-finish spray, then weathered with Testor’s gold, a gold paint pen, a green-gold paint pen and india ink wash. The sigil and corners were bonded to the case using super glue,  accelerator and some Gorilla Glue for good measure. The legs were glued the same way, but also have small screws in the bottom for rigidity.

As its a prototype, I haven’t decided if I’ll keep it. Any cultists looking for somewhere to store a dried heart or tentacle, feel free to make an offer.

HIC Prusa i3 3DP-11 – config file for Marlin

// November 29th, 2015 // Comments Off on HIC Prusa i3 3DP-11 – config file for Marlin // tech

[2016 update: I’m currently running two Lulzbot Taz, but I’ve added a second extruder to the Prusa below. Once I starttinkering with it again I’ll post the config for that here as well since this post got kind of popular. I guess a lot of other people also had issues getting the proper settings from HIC.]

3dp-11I had a lot of trouble finding an example Configuration.h for my new HIC/HICTOP 3DP-11 Prusa i3 while trying to tune the machine a bit (turned out my Y axis pulley gear was just slipping). I did find this page on about a previous issue and a link to a zip file with Marlin and a config file, but I guess this was for the earlier acrylic version. My new aluminum version had several differences (not the least of which was the homing settings). So I set out to make my own. Enjoy at your own risk.

Update: Crazy fun fact, Internet. Maggie is a girl’s name. Pretty much worldwide. I’m a girl. I only mention this because people keep linking to “this “guy’s page” and don’t seem to realize this little detail (although I seriously doubt any of them have ever met a dude named Maggie.) So, please? A little respect? Thus endeth the update.

#ImAStarCitizen lady-type-character-person

// September 8th, 2015 // Comments Off on #ImAStarCitizen lady-type-character-person // art, games

A very cool thing that’s currently making the rounds of Cool Things is the Star Citizen #ImAStarCitizen info card. Tom Banks has created this for fun and with the tacit blessing (and some assets) from CIG.

However, what he doesn’t currently have is templates for the women of Star Citizen (mostly because the there aren’t any yet. The in-game characters are all still in the work). So, based on some concept art, I created two templates lady pilots and explorers can use for now when creating a card (until Tom gets hold of some real ones). Feel free to copy one of the image links below and put them in the custom box here:

Sort of an update: My Motorola story, good and bad

// April 22nd, 2015 // Comments Off on Sort of an update: My Motorola story, good and bad // Rants, tech

Good story gone bad


So, about that MotoX. It’s a great phone. I really do like it. In fact, I’d say I love it. It’s fast, Lollipop is great and all the little integrations (shake for camera, OLED screen low-power notifications, etc.), all very nice It’s a great phone and I haven’t regretted the switch from Apple yet. Unfortunately, the screen is cracked* on mine and I need to get it fixed. And it was from this that I discovered the dark downside to the Moto X… Motorola support.

Motorola repair support is terrible.

If only I’d read all the “Don’t use Motorola’s Advance Exchange program! You’ll regret it!” warnings on forums, I could have saved myself the headache.

What’s the Motorola Advance Exchange program?
Motorola sends a replacement phone, puts hold on your credit card ($500), you send back broken phone.Replacement phone ships to you within 4 business days of request. You pay for repair cost, keep the replacement phone.

In theory that’s how it works… In practice? Not so much.

My Experience with Advance Exchange for my new MotoX bears no resemblance

4/11 – Submit Advance Exchange request. Motorola promptly puts hold put on card. Ah, look. It’s $500 + $125 + tax instead of the $500 they tell you the hold will be. Oh, well, no big deal.

4/16 – Online status doesn’t show anything shipped yet. Oh, well, no big deal

4/17 – Online status still shows no replacement has shipped. Almost call, but decide to give them more time and I wait until Monday. No big deal… right?

4/20 – Initiate online chat. They say they need to escalate. Someone from repair escalations calls me. Says nothing has happened because they don’t have a phone like mine to send and have to build it. No reason for why they didn’t bother to tell me this. I say it’s been long enough and if I’d  settle for whatever 32GB Moto X they have in stock, even without leather and in any color, would that speed it up. Sure, they say. Agent says they can send me a plain black one and he’ll get right on that. Fine, I say.

4/22 – I check and see that status STILL says no phone shipped even though they implied this was all sorted and on the way.

I email Motorola support:

My Advance Exchange # xxxxxx-xxxxxx still doesn’t show anything shipped. I originally submitted it 4/11 and on 4/20 spoke with someone and was told nothing had happened because they didn’t have a suitable phone in stock. I said at that point I was OK with a stock replacement phone if that would speed things up (I have a white 32GB with leather with a cracked screen, he said they could send a plain black 32GB).

But when I check online it still doesn’t show a replacement shipped. Could you please check on this and make sure it hasn’t gotten stalled again? – Thanks

Motorola replies:


Thanks for reaching out to Motorola. I’ve reviewed your e-mail and I’m ready to help. Upon checking on this incident xxxxxx-xxxxxxx, the phone is not yet shipped because when you called last April 20 and agreed to have a different device because of the stock, the process started again. You will received the device within 5 working days from now as part of the replacement process.

We hope that you find this information useful and we look forward to assisting you in the future.

Thank you for contacting Motorola e-mail support.

Best Regards,

Motorola Customer Support

I reply:

Wait, wait. This is ludicrous. I was going to have to wait a business week to get an equivalent replacement, a week that’s now passed, but now I need to wait even longer to get a lesser device ‘faster’?

Please cancel this advance exchange. Given that nothing has happened yet I assume that won’t be a problem. I’ll investigate repair or return options with my carrier. This is ridiculous.

Please let me know that the exchange is canceled. I’m not waiting two business weeks for a downgraded phone. I’ll live with the cracked screen for now.

Thanks. I realize this is not your fault, but being an ex-Apple customer who just made the switch to a Motorola phone, I can see why their service still ranks so much higher. I would have had a replacement in-hand a week ago.

Yes. THE ENTIRE PROCESS @#$&%@# RESET back to square one and now the cheaper, plain black phone will ship WITHIN 5 MORE BUSINESS DAYS.

Why on Earth would I want to wait even longer than I would have for them to go build a damned equivalent phone just to get a cheaper, lesser, plain black replacement phone for my nice white, leather-backed phone? Who could possibly think that’s a bettter solution and one likely to make me happy??? How is ‘you can wait 7-10 business days for the same, or you can wait 11+ business days for a lesser one a viable option?

If I didn’t like this phone so much, I’d pay for the repair and just send the whole goddamned thing back.

Logic, @MotorolaSupport, you’re doing it wrong. Also support. You’re totally doing that wrong.

UPDATE: So someone called me back today (4/23) to hand me off to another person. Then came back to say they couldn’t do anything because their system was broken. Then another person called later and I explained I wanted the return cancelled. They said I could have the black phone within “umm… 48… maybe 72 hours”. I said no. Cancel. He also explained that the original problem was my request had been sent to ‘the wrong warehouse’ where I suppose it would have sat and rotted had I not been nagging them. But, again, no one told me. It just sat in limbo for a week. After being on hold again (the the loud, distorted 15 second violin concerto loop again, holy crap is that crazy-making) for a while the guy said it was canceled. I thanked him and went on with my life.

Super-heavy-duty case should be here tomorrow. I can live with the crack for a while…

UPDATE: Repair cost charged to my card on 4/25… two days after this was supposed to be canceled.

UPDATE 2: It just occurred to me that I’ve engaged 6 or 7 human beings during this whole process. And _not_ the human beings whose job it is to process the exchange. Just imagine that. For a process that begins online driven by the customer, which then presumably goes into an automated binning system where a matching phone is found and marked for dispatch (or, unlike my experience, when no matching device is available the customer is notified of a delay and offered an alternative or timeline) and _then_ a human being gets the work order and processes the outgoing phone. Later another person processes the incoming device. But, no, 6 or 7 people have stumbled over one return before anyone even had a chance to process the initial exchange. What a waste of resources and money because someone can’t work out their returns pipeline in such a way that it’s even marginally reliable.

There’s no excuse for such bumbling, Motorola. You’re a grown up technology company.

UPDATE 3: Hi. It’s May 8th and Motorola still hasn’t refunded the repair fee they charged to my card. I sent a support email which, of course, just came back ‘we need your number so someone can call you’. No. No one needs to take up any more of my damned time, they just need to do their job and fulfill their promises. And you HAVE my number already! *sigh* I’m done with Motorola. No matter how much I like this phone (and I do! I really, really do!), it’s not worth worrying that should I need support I’m going to have to push the ball up hill for them at every turn. Every single time the wheels started to move in the above narrative it was because I’d initiated it. I’M THE CUSTOMER, NOT CUSTOMER SUPPORT!

God I feel like all I do is whine on this blog now, but… for the love of everything good how can a multi-billion dollar 21st century tech company’s tech support seem like it’s being phoned in [literally] from the mid-20th century? I honestly wouldn’t be surprised if they’re using pen and paper still…

* – UPDATE: The following is all irrelevant now as I’ve just kept the phone and got a heavy-duty case to protect it. I’m living with the crack (it’s in the upper left an mostly out of the way).

The irony of the cracked screen is that after looking down to find it cracked (I’ve no idea of the cause) one day, a bit later I actually dropped it and dinged the metal on that same corner. So I’m definitely on the hook for the repair cost. There’s no way they could know that I dropped it after the screen cracked and maybe I did hit it on something to crack the screen… Again, I have no idea. I only mention it here as a “ain’t that always the way” story.


Upheavals in my tech life – Part 1: Amazon Echo

// February 7th, 2015 // Comments Off on Upheavals in my tech life – Part 1: Amazon Echo // Echo, musings, Rambling, tech

UPDATE: I still like Echo a lot and it keeps getting better. They’re constantly adding features (including IFTTT and home automation support!) and everything just works. TuneIn had issues one time, but that’s it. I’m extremely happy with it as a household assistant and as a bluetooth audio system.


I’ve made or am making some big changes in some small areas of my life. Mostly around technology. Being a self-described ‘technologist’ that means I have to write about it. Hi.

*** Feel free to skip this list and jump right to #4 if you just wanna know about Echo ***

Chief among these are:

1) I’ve jumped ship from iPhone to Android. My new phone is a 2nd generation Moto X running Android 5 Lollipop. As some of you know, Apple and I have gone from a blissful to a troubled relationship of late. Linux boxen out-number Macs in my house now — I’ve even broken down and built a Windows gaming machine because… Borderlands Pre-Sequel, ’nuff said — and my iTunes music library has gone from being a warm, fuzzy vault where Apple kept everything for me to a technological albatross that I had to pull what felt like a bank heist to liberate everything from so I could access all my music from my new phone. Anybody want to buy a Verizon iPhone 5?

2) Along with ditching iPhone, I’m finally weaning myself off Safari (after all, I’m on OSX less and less). It’s a small thing, yes. But when I get around to writing about that, there’s more to it than just changing browsers. Some of the thoughts rattling around in my heads about this: Safari is closed-door Apple kit, but it doesn’t feel as… invasive… as Google Chrome. And Safari is fast. When it’s not beach-balling. But it’s just time to let it go. So do I invest my life more into Google’s ecosystem [and its attendant information Hoovering juggernaut] by using Chrome? I am using their OS now on my phone. And Chromecast is super handy. Or do I switch fully to Firefox all around, despite my love/hate relationship with it? It’s all I use on my Linux machines, but… dammit it pisses me off some times. Or do I split the difference with Chromium? In the end, the integration of all these with things like Lastpass, Yubikey and sometimes 1Password are big deals to me. And they all behave differently. So it’s not an easy decision.

3) Dish’s Sling TV. I haz it. I also haz Roku and AppleTV. I subscribe to Netflix, Fandor and AcornTV. I’ve been threatening, much like George Lucas saying he’s going to go off and do his ‘experimental movies’ and then never doing so, to cut the cord on my cable TV. So now that I have Sling TV and I know I can still watch Venture Bros and Adventure Time, I’m going to do a simulated cord cut. I’m going to rely on everything but my cable TV for a week (starting Monday) and see how that goes. I’ll tell you right up front that I’m gonna break this rule. I’m still gonna watch Archer on Thursdays on my TiVo. And I may use HBO GO, even though it’s tied to my cable subscription. The latter is OK in my book as HBO has announced that GO a la carte is coming. I gotta watch Game of Thrones, y’all. And can I just say, FX and AMC, please get on Sling TV and this will all get tied up with a neat little bow.

4) I have an Amazon Echo. Yes, I’m one of those people who jumped on it first thing. I know. I know. But that’s the thing I want to talk about, now that I’ve bored you to death with all the above. Unless you skipped straight here. In which case, “Weakling!”

First, let me cut right to the chase. I like it. It’s $99 well-spent and I’m happy with my purchase. I’ve tinkered around with computer assistants in the past and they all were terrible. So when Amazon said I could have a PDA with good voice recognition that could play NPR and tell me how old John Hurt is as I wallowed on the couch, I signed right up.

Is it just a glorified Siri? Yes. Or, more precisely, a glorified Cortana. But that’s all it purports to be, if we’re honest. Their ad, the one with the ‘early Richard Dreyfuss’ asshole dad, shows you it can play music, be a Bluetooth speaker, read Wikipedia, tell you the weather or how tall Mount Everest is. That’s what it does. Oh, and shopping and to-do lists which I’ll get to in a sec. But the point being: It was designed to pretty much be a glorified Siri. Or Cortana.

As a glorified Cortana it works really well.



Yes, I spent four hours the first night dicking around with this thing and it not working. I’d quit and come back. I couldn’t accept defeat. I’d search the ‘Net and try other things. The app just sat and spun. And no, I didn’t call Amazon support because I was not prepared to patiently sit through someone telling me to reboot my router, make sure it’s plugged in, etc. My first damned router was configured with a text file and telnet, FFS. This ain’t my first day at the rodeo.

The way Echo’s setup works is you download an app (Mac, PC< Android or iOS), turn on Echo and it will go into setup mode (the ring rotates orange – there are audio prompts along the way), and you will then connect to it as though it were a wireless access point. If you get stuck here, find that rest button. You then select your WiFi SSID and enter your WiFi password (I believe Echo has two radios, as outlined below). In theory, this is where it connects and finishes setting up, culminating in Echo telling you it’s ready. This is where I was failing. Initially I couldn’t even get to the WiFi setup part.

And the app doesn’t give you access to the Help tab… until you’re done setting up. Duh.

Finally I found someone on Twitter mentioning that there’s a tiny reset button hole on the bottom. Using that to reset Echo and start fresh allowed me to finally get to the WiFi setup and connect Echo to my WAP. Or so I thought. Here it just hung again. Spinning forever. I tried this from my Android phone, an iPhone, a laptop and from an Amazon Kindle FireHD (I bought it on a whim long ago, don’t judge). No go on any of them. And I thought it weird how I still had the same IP address on my laptop when connected to the Echo

A bit more searching led me to a post from someone who had talked with Amazon only to find that Echo uses the same IP range (192.168.11.x) for its internal AP as my router does. And specifically it uses for the Echo. Even changing my router’s LAN IP to something other than 11.1 didn’t help. Presumably this is because with Echo being an AP and simultaneously being a WiFi client, there’s a routing conflict and the Echo probably ends up talking to itself instead of bridging the two networks.

So I set up a laptop to share its ethernet connection over WiFi, ran the setup again selecting this new access point (whose internal DHCP was using 10.0.1.x)… et voila. Echo connected and started working.


Seriously. I do enjoy it now that it’s working. Saying “Alexa, play NPR” and it almost immediately starting a stream of my local NPR stattion (WBUR) is so much quicker and friendlier than doing this from another device (unlock, open app, pair to bluetooth speakers, etc.) And, on top of it all, it sounds really good. It sounds like a decent Bluetooth speaker system. Enough bottom end for most things and with clear highs and mids. Today I woke up, padded off to the bathroom and called out “Alexa, play Kraftwerk Man Machine.” (The Echo is in my living room, close to the kitchen door.) I enjoyed some of my favorite krautrock as I woke up and made some coffee. Not in the bathroom. I made the coffee in the kitchen. Weirdo.

I checked the weather, since more snow is on the way, listened to what it calls a “flash briefing” of news and then decided to listen to NPR all day. Something I enjoy doing on weekends but often don’t because I hate dinking around with the radio and sometimes reception is crap. And streaming it involves too many steps, so I just don’t. I end up in silence or listening to audio books form my phone. But today I listened to Wait Wait and some other fare and was able to say “Alexa, pause” when I needed to go back and take care of the outcome of that coffee and then “Alexa, continue” when I was back in the kitchen working on a Tricorder I was adding leather to. It’s sweet. Everybody needs a leather-covered Tricorder. I’ll sell you one if you want. But I digress.

As I was working, I realized I should get some Armor All to shine up this leather.
“Alexa, add Armor All to my shopping list.”
“I’ve added ‘Armor All’ to your shopping list.”
“Oh. I’m out of tea, as well. Alexa, add tea to my shopping list.”
“I’ve added ‘tea’ to your shopping list.”
Later I decided to go to Target for a few things before the next potential snowcano/icenami (I’m trying to stop using snowpocalypse). So while there I opened the shopping list and bought the things I’d put there earlier.

Note to Amazon: Notice how I did not buy these items on Why? Because the shopping list is separate from all Amazon wish lists. It is not integrated into in any way. The shopping and to-do lists ONLY exist in the Echo app. So it was more convenient for me to, while at a shopping establishment, use the list to buy things while I was there.

And, finally, yes I’ve made Echo cuss and say “boobies” and tell me jokes. I’ve had her ignore me when she thought I was either not being serious or she just couldn’t sort out what I said. And sometimes she just doesn’t get things like “Alexa, what year was the book ‘1984’ published?” Some of that is her, some is Bing, her search engine. And, by the way, Mike J. Nichols, sometimes you’re the general manager at Bing or, occasionally, you’re a “film editor originally from Illinois”. But never The phantom Editor (I decided to use your name as a test as I was listening to Chris Taylor’s book at the time.)

So far I’ve been very pleased with both the accuracy of things she does understand and the speed. In fact, I was playing a Youtube video review of Echo and she would perk up and answer the questions heard in the video at the exact same moment as the Echo in the video. Recognizing speech and performing a near-instantaneous lookup and reply is, let’s be honest here, pretty damned cool.

Am I happy with my $99 Wikipedia reader, music player and NPR indulge-my-laziness player? Yep. Knowing that she’ll do more in future is great, but I’m fairly happy with what [granted, little] she does now.

Oh. FYI – “In Cambridge there’s a winter storm warning in effect until 1 AM Tuesday, February 10th. The current weather is 27 degrees with flurries. Throughout the night you can expect more of the same with a low of 26 degrees.” :)

Read more nonsense at The Outhouse.
