Open Source 3 Channel Frequency Generator

ehb,

IRF 730s go up to 400v, each FET can handle about 5amp, you can parallel them for more current.

Arduinos are as tuff as any PCB I think, but the stackable shields will fall apart if shaken too much, nothing a few rubber bands won´t stop though

Hey Yucca and all others interested,

I received my LCD shield today, hooray! Looks cool, esp. for that price (man the british pound is down)
So now I wanted to go ahead and load up your source code, and realized you've taken it down. Humm
It would be nice if you could post the source code in .txt form here, or maybe use http://pastebin.com/
I'd be grateful, I'd love to break some fets soon

Greets, ehb

Hi EHB,

I've attached it to this post as a .txt file, just copy and paste into your Arduino.exe programmer/editor and compile.

You will have to add the LCD4Bit_mod library to the project.

I've just read that nuelectronics have changed the LCD board since I purchased mine and they use a pin that I have used for the piezo, so you may have to mod the pin assignment for the piezo in the code. It should work ok though as long as you have the modified library from nuelectronics.

Let me know how it goes.

Yucca.

You're da man! 
I'll try it asap, first sleep.

Thanks alot!

It works like a charme, at least the LCD says so
Great work man.
Only problems I had were with the includes of io.h and interrupt.h. Arduino0012 software reports: "23: error: interrupt.h: No such file or directory".
Prefixing the filenames with avr/ fixed this problem though.

Now I've gotta figure out how to attach a jog wheel and lateron the mosfets.
I'll get an oscope tomorrow, so I can check the output frequencies.

Really cool stuff, now go out and celebrate new year
