Simulating 3-phase AC for energy monitor testing

Thursday, October 12th, 2017

Tisham Dhar blogged about his 3-phase synthesizer: Finding 3-phase is difficult, convincing the owner of the said supply to test some home made hardware is even more so. After building a 3-phase energy monitor my testing options for it appeared very limited. So I set about making my own low-cost 3-phase...

Teensy MIDI USB foot controller for controlling Mobius Looper

Thursday, August 21st, 2014

Thrifleganger wrote this instructable detailing his Teensy MIDI USB foot controller for controlling Mobius Looper: The concept is quite simple and straightforward. You press a button, the arduino interprets the signal arriving from the button as a midi "control change" signal (typically represented as MIDI CC), and this signal can be mapped...

Using a Wii Nunchuk as an earthquake sensor

Friday, May 18th, 2012

Here is an open source earthquake sensor based on the Wii Nunchuk. A Teensy is used to read the I2C accelerometer output: This article explores the suitability of a Wii nunchuk based USB accelerometer as an earthquake sensor for the Quake-Catcher Network (QCN) project. It examines the nunchuk over several metrics:...

Defcon 19: Hacking over power lines

Friday, November 4th, 2011

Dave Kennedy (ReL1K) presented this talk at last summer's Defcon 19 conference demonstrating the relative insecurity of home automation devices, such as X10, HomePlug and ZWave modules, which communicate either locally over power lines or via RF in the ISM bands. The presentation covers usage of the Teensy Arduino-based device...

Arduino IDE hack speeds up code compile

Wednesday, September 14th, 2011

Paul Stoffregen over at PJRC sent us a link to this video highlighting how to modify the Arduino IDE by editing the boards.txt file to allow the compiler to use precompiled files. This helps to speed up the overall compile and upload process. A cool enhancement originally developed for the...
