To keep things easy for the judges, this post contains links to all the requirements of the Hackaday Prize Semifinals. It will be updated as progress is made, up to the deadline (Sept. 28).Video: Princess Sparkle and I have been working on our...
The magnetometer arrived on Thursday (yay for Adafruit and their speedy shipping!); today I spent most of the day getting it working.There were a few issues which I needed to overcome.First, I had to read the raw values over i2c. This is easy...
To allow for automatic magnetometer calibration, I decided to write a simple python program. It can do all the calibration which the Universal Controller can do (joint angles and foot x/y/z adjustments), as well as calibrate the magnetometer offsets,...
The machine is coming along nicely X,Y and Z axis are done, mounting bed is done.I do not want the machine to be completely controlled by gcode, I also want to be able to manually control all axis. To reach this goal I will add a long digital caliper...

Woah! It took me a while to figure out how to get the video from My Nokia Lumia device to Ubuntu after my Windows Laptop crashed. I tried a couple of ways like Bluetooth, Wifi,SD Card etc. Ubuntu (12.04LTS 64bit) does understand MTP natively. So, there...
The "undervoltage protection and dusk light switch" has two purposes:It switches the load off as soon as a critical (low) voltage is reached.It disables the output as long as the solar panel still provides more than an adjustable voltage (e.g. by day...
Finally, today is a day with sunny weather + some hours of free time :DQuestion: At which voltage should I use my (unknown type) solar panel to get maximum power out of it? Is it really that worse if I use it a few volts above or below? Is it worth the...
Uh oh. I'm in the competition. Guess I better get to work.There's no chance of having the Decapede ready any time soon, so I bought some stepper drivers off eBay (Geeetech DRV8825) and started wiring them up on a breadboard and connecting them...
It all started when I encountered that old white Brother AX-110 electronic typewriter. The daisy wheel was broken so I decided to crack it open and see what‘s inside.Surprisingly, there was not much inside: Just a little circuit board with a microcontroller,...
I got the first prototype boards in for MakerMod a few weeks ago. First up are some of the boards for designing circuits on:PTH Proto has both a male and female dual row MakerMod connector. The central two rows are VCC and GND rails, and the outer holes...
In a world of tech fairy tales, there would be nothing wrong with telling the Spark Core story as yet-another Kickstarter miracle that surprised everyone, especially its founders, who were subsequently left with only one option - to go ahead and change...
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...
