Scope And Schmitt Trigger Oscillator

A nice bonus of the scope is that it is based on an AVR microcontroller and the creator provides documentation to help get you started hacking the device. Learn to program the scope here, and how to add an external trigger here. If you are interested you can read the operating instructions here.

DIY cardboard MIDI controller

I am planning on using this Arduino based prototype to experiment with fine tuning the firmware for a line of boutique and custom MIDI controllers. The final project will be ported to C using the AVR C library and I will make the whole project open source.

Here is a look at the back. I just used whatever pots I had, so they aren’t matched. The LCD is a serial one from SparkFun.
