Dzl's Evil Genius Lair: Hacking electric wheelchair drive
http://dzlsevilgeniuslair.blogspot.com/2014/05/hacking-electric-wheelchair-drive.html
Dzl's Evil Genius Lair. Sunday, May 11, 2014. Hacking electric wheelchair drive. While building some robots for a museum we came up with the idea of using an electric wheelchair as the base for the robot. Not wanting to replace the electronics we gave it a shot to try to use the existing motor driver and control it from an Arduino. On inspection it turned out to be a very common Penny and Giles Pilot plus drive. The physical connection is using a propitiatory 6 way connector. Probably for safety reasons ...

Dzl's Evil Genius Lair: Induction heater
http://dzlsevilgeniuslair.blogspot.com/2015/02/induction-heater.html
Dzl's Evil Genius Lair. Monday, February 2, 2015. We have been experimenting with differnt kinds of metal casting. One of the methods is "lost PLA casting" where a 3D printed PLA. Model is covered with plaster and made to melt away when molten metal is poured over it. Problem is that the metal (aluminium in this case) cools off too quickly when it contacts the plastic. I wanted to find a method to keep the metal molten while inside the mold. One solution seemed to be using induction heating.

Dzl's Evil Genius Lair: Data visualizer for drone tracker
http://dzlsevilgeniuslair.blogspot.com/2013/11/data-visualizer-for-drone-tracker.html
Dzl's Evil Genius Lair. Friday, November 22, 2013. Data visualizer for drone tracker. I needed a way to visualize the spatial data from the drone tracking software. I wrote a OpenFrameworks program to do this. Click here. Or on image to see it in action. Subscribe to: Post Comments (Atom). Data visualizer for drone tracker. Did a hover test. Tangible paramter tuning thingy. The loop has been closed. Controlling toy quadcopter(s) with Arduino. Fun with cheap toy quadcopters.

Dzl's Evil Genius Lair: APRS transponder now with 1W output
http://dzlsevilgeniuslair.blogspot.com/2014/11/aprs-transponder-now-with-1w-output.html
Dzl's Evil Genius Lair. Friday, November 7, 2014. APRS transponder now with 1W output. Did some more work on the minimalistic APRS transponder. Made a test circuit board that allowed for adjusting component values. It now output 1Watt at 7.2V. UPDATE: Some pins have changed so this schematic is NOT compatible with the code posted earlier. Added a voltage regulator for 2LiPo cell operation. Here is a quick video. Of my test setup transmitting 1W. Subscribe to: Post Comments (Atom).

Dzl's Evil Genius Lair: Fun with thermopile generator
http://dzlsevilgeniuslair.blogspot.com/2014/01/fun-with-thermopile-generator.html
Dzl's Evil Genius Lair. Friday, January 10, 2014. Fun with thermopile generator. Got a bag of Peltier cooling elements. Thanks Dan) and experimented with using them as thermoelectric generators. These devices will generate an electric current when subjected to a temperature difference. When placed on a hot oven they will generate about 1,8V and 650mA for a few seconds and then fade out due to heat conducting through the element and cancelling out the temperature difference. Of the thing going. Thermoelec...

Dzl's Evil Genius Lair: The_synth Arduino library got an upgrade
http://dzlsevilgeniuslair.blogspot.com/2014/04/thesynth-arduino-library-got-upgrade.html
Dzl's Evil Genius Lair. Saturday, April 26, 2014. The synth Arduino library got an upgrade. A while ago I released a Arduino synthesizer library. A new and improved version is now available github:. Https:/ github.com/dzlonline/the synth. I was asked to play a small concert at my friends PhD defense. Using an Arduino running this library. Listen to the result here. Https:/ dl.dropboxusercontent.com/u/2248531/the synth concert.mp3. July 3, 2015 at 11:09 PM. December 28, 2015 at 9:13 PM.

Dzl's Evil Genius Lair: The loop has been closed
http://dzlsevilgeniuslair.blogspot.com/2013/11/the-loop-has-been-closed.html
Dzl's Evil Genius Lair. Saturday, November 16, 2013. The loop has been closed. After a lot of crashing and swearing in the lair closed-loop control of the HCDs has now been achieved! The rough control parameters has been established so autonomous take off, flight and landing can be continously reproduced. Now I need to fine tune the flight controller software and package everything nicely into something others can use too. Subscribe to: Post Comments (Atom). Data visualizer for drone tracker.

Dzl's Evil Genius Lair: Tone/DTMF detector library for Arduino
http://dzlsevilgeniuslair.blogspot.com/2014/10/tonedtmf-detector-library-for-arduino.html
Dzl's Evil Genius Lair. Tuesday, October 28, 2014. Tone/DTMF detector library for Arduino. Was playing with some cheap radios. And decided that the keypad DTMF tones could be used for remote control. I had some old source that detected touch tones using a AVR microcontroller and decided to convert it for Arduino. This resulted in a library that detect audio tones played into any Arduino pin. The audio is first clipped to a 1-bit signal (played loudly into a digital pin) then sampled at 10kHz.
