Just build my own version of AVR microcontroller USB programmer a few weeks ago. The original version can be found here. You can download the schematic and the board circuit via the below link. This is 2-sided boards, consists of SMD components and a few thru-hole component. If you live around Malaysia and don’t know where to get supply of those components and parts just leave a comment here. Most components I managed to get at Jalan Pasar, KL.

Schematic and Board (EAGLE files) can be downloaded here. For the firmware, it can be downloaded at their official site.

Do you wonder how the homemade PCB (Printed Circuit Board) was made? There are a few technique to do that. The famous technique is the toner transfer technique. Besides that the other technique is by UV exposure board. However what i want to show is the toner transfer technique which means transferring toner printing into the PCB. So we need…

1. Thinner
2. Ferric Chloride
3. Laminating Machine / Cloth iron
4. Autosol
5. Drill
6. Laser Printer
