Remember in the late 90s and early 2000s when everything had blue LEDs in them? Blinding blue LEDs that lit up a dark room like a Christmas tree? Nobel prize. There’s a good /r/askscience thread on why this is so important. The TL;DR is that it’s tough to put a p-type layer on gallium nitride.
Have a Segway and you’re a member of the 501st? Here’s your Halloween costume. It’s a model of the Aratech 74-Z speeder bike, most famously seen careening into the side of trees on the forest moon of Endor.
[Andrew] needed something to do and machined an iPhone 5 out of a block of aluminum. Here’s the video of icon labels being engraved. The machine is a Denford Triac with a six station auto tool changer. He’s running Mach3, and according to him everything – including the correct tooling – cost far too much money.
Another [Andrew] was working the LEGO booth at Maker Faire New York and has finally gotten his LEGO Mindstorms Minecraft Creeper build written up. Yes, it’s probably smarter than your average Minecraft Creeper, and this one also blows up. He also had a physical version of the classic video game from 1979, Lunar Lander. Both are extremely awesome builds, and a great way to attract kids of all ages to a booth.
[Wilfred] was testing a titanium 3D printer at work and was looking for something to print. The skull ‘n wrenches was a suitable candidate, and the results are fantastic. From [Wilfred]: “Just out of the printer the logo looks amazing because it isn’t oxidized yet (inside the printer is an Argon atmosphere) Then the logo moves to an oven to anneal the stress made by the laser. But then it gets brown and ugly. After sandblasting we get a lovely bluish color as you can see in the last picture.”
The folks at Lulzbot/Aleph Objects are experimenting with their yet-to-be-released printer, codenamed ‘Begonia’. They’re 2D printing, strangely enough, and for only using a standard Bic pen, the results look great.
Everyone is going crazy over the ESP8266 UART to WiFi module. There’s another module that came up on Seeed recently, the EMW3162. It’s an ARM Cortex M3 with plenty of Flash, has 802.11 b/g/n, and it’s $8.50 USD. Out of stock, of course.
Where is the rest of Wilfreds pictures?
I was wondering the same thing
Anyone have a link to the STL file used by Wilfred? Or any suitable STL for the logo? I was looking for one to print, but haven’t found a good one yet.
Here is one HAD did.

Thanks!
Who (what?) wrote the “Introduction” of the EMW3162?
http://www.seeedstudio.com/depot/EMW3162-WiFi-Module-p-2122.html
I’ll be forgiving if English is not their primary language.
You know who seeedstudio are and where they are located, right?
No, I didn’t, thankfully another commenter enlightened me.
Designer of the board, MXCHIP, is a Chinese firm and Seeed is based in China.
This board looks interesting. Not quite a full router nor big enough to run Linux. 120MHz, M3 with 1MB of FLASH and 128kB of SRAM is a good size for running a RTOS + network stack and still leave enough space for running user application software. Good enough stand alone board and not required yet another external microcontroller to talk to it.
Now if only there are source code to the drivers for to talk to the WLAN side which looks like it is connected via SDIO. (SD card based radio)
Can anyone explain what’s going on with that PCB trace antenna on the EMW3162? I’ve never seen one that looks like that: small through holes along the length of the antenna and a large one at the base?
Seems like simply a way to make both sides of the board act as one piece of copper, but I’m no RF engineer.

An OS to run on it: https://github.com/MXCHIP/MICO
Hmm… $8.50 for a mini dev board with that STM32 is pretty good even if you never use the WiFi.
Agree!
where to find instruction (understandable) for MICO ? dont understand how to use it..
Aluminum milled iphones are so yesterday. These guys have a better option:

Now you post it! AFTER their campaign has failed! B^)
