I can't say I'm thrilled with how Slic3r built the support under the badge. I snapped a razor trying to get it out. I decided to reprint and deepen the design to make it taller so the badge won't stick out so far from your chest. Once it was done, I...

I am now in the process of moving all the documentation and files to this site. This project is quite new (the original controller has been around for a few years, but it was specific to a quadcopter implementation and was quite awkward and unwieldy;...
PS2 controllers are actually pretty easy to interface with; they use SPI mode 3 (CPOL=1 and CPHA=1); while in theory you could use the SPI hardware on an AVR to talk directly to the controller, I chose to just write my own (adapt my own) bit-banging...
If you have a Universal Controller, and you have taken the recent protocol changes, please pull the latest code and redeploy. There are a couple of bug fixes which I have just pushed which, while quite simple, can make a large impact on how the...
When I first started this project, I was using the PWM library I wrote a while back, for use with my quadcopter. It is pretty simple: you can configure as many pins as you want, set a single period for all of them, and set individual phases on...
An alternative to reducing the weight (which, given that the servos + batteries currently comprise more than half of the overall weight, and cannot be reduced) is to design the frame + legs in such a way that the servos are not supporting the weight...
I just ordered 10 PCBs for Stubby. I am trying out the semi-joke service which is http://dirtypcbs.com/ - nice and simple ordering without any fuss; it is slightly cheaper than Seeed studio as well (for orders to Canada at least),...

I got the RAM board all wired up, and it works correctly. It doesn't work as it should, but it works as it's wired. Just look at the schematic:And then think about the 8080/8085/Z80 and how they interact with I/O. That's right. If I write or read to...
I already had on hand a few HC-SR04 ultrasonic range sensors that I purchased from Amazon for another project that got shelved. (These things are CHEAP!) Just to make sure the sensor would work as hoped I hooked it up on a breadboard. ...
Following our post on IoT platforms, Spark guys reached out and asked if we can do a full interview. Given the unique position Spak is currently in (post-successful Kickstarter, betting heavily on Open Hardware and Open Software...) - we were more...
There exists a type of gas laser which achieves much higher power densities at the cost of destroying its own lasmix. It vents the lasmix from a bottle, though the optic cavity, and from there presumably into the atmosphere. It does this for the sake...
Solutions create problems create solutions create problems....Added the rotation sensors. The caps over both sensors do two jobs. The first is to keep grit out - I'm thinking ahead about the Ingress Protection rating. The second is to hold the sensor...
