Symmetric Power Supply 0-70V @ 5A – Update
I mounted the resistors and transistors on the heat sink:
And I made a switching pcb.

Tube Amp – Update
The amplifier is almost finished, but testing points out that I have a nasty 50Hz buzz on the output.

SC Analyser 2005
This is a project from Elektor April 2005 (Link).
I want to build this circuit because I have a big box of transistors etc. of witch the working is unknown (They are de-soldered). This circuit uses a PIC16F876, and coincidental that I have 2 off those.

AVR Programmer
Sometimes it is handy to have a avr programmer, so I don’t need to bother other people for it.
I first wanted a programmer to use on my serial port, but I couldn’t find one. Then I got a tip to build a programmer that works with the parallel port. I found this design on circuits online en decided to build it. http://www.circuitsonline.net/circuits/view/112

250W Subwoofer Amplifier
I’m building a 5.1 surround sound system. Therefore I need a subwoofer. This project is the amp for that subwoofer.
The circuit drawings that I want to use for this project can found here:

CNC drill/mill machine V2 – Mechanical Part – Update
I finished a part of the Z-axis. Now I can mount it to the Y-axis. However it is not completely finished but I quit for today :p.
