Pickit 2 3.3v Voltage converter

I found a schematic online for a 3.3v logic converter for the Pickit 2, and decided to make a board for it. The key was making it very small. I wanted something I could just fit in my pocket with thePickit 2 programmer. The design has to be tested but the schematic looked sound. If you want a copy of the board in PDF to make your own just send me a message, its going to take me a little while to put the files on the server.

So I made an arduino board! Well not quite, its a little different more like the barebones arduino idea with surface mount parts. I wanted something small with a tiny power regulator for 5v logic only, which suited my needs better than some of the other boards available. Regardless the files are available if you want them.

So I was going through some old posts and decided to see what Julien Bayle of is doing and was looking at the monome clone called the Bonome. This project really excited me it was a meeting of the minds with so many different people, hardware, software, firmware, and of course we can not forget the creators the original monome team.

Now with my new project I have decided to switch to PIC32. Why because I want to learn another platform and there are a few other reasons such as the support for DSP with there new library. Less coding means more fun for me.

This board is something new a PIC32 development system designed for audio. I have some interesting needs for art installation ideas however, the realization of the works have been halted due in part to the extreme cost of audio synthesizers. Of course there is a large amount of intellectual property under the hood of a synth, but developing your own can be rewarding, and teaches you much about synthesis techniques. There is a forum post started here on Electro-Music. Inventor has designed a system called eChuck based on the Chuck programming language; essentially it is an audio programming language. The eChuck concept will allow people to port that idea onto hardware.

I expect to be in prototype soon, I just need to hear back from a board house on the cost of manufacture of a few prototypes. In the mean time a programming application framework is being developed to meat my needs, and additionally board for tactile input and visual output are in the works. Which brings me back the the bonome, I have designed the unit with a header to connect to the 8x8 keypad / led matrix. If I can port the code over I will but it is more likely that I will write the interface to suit my own uses internally for sequencing. But its a way to reuse some older equipment if you have it.

Stay tuned for additional info on the project either here or on the Electro-music forum.
