This page describes a new way to make PCBs with a laser printer, water release paper and a laminating machine.

• MATERIAL REQUIRED 
  • PCB drawing software.
  • Laser printer with a resolution of better than 600 dpi or a laser photo-copier.
  • Water release paper.
  • Green TRF Film.
  • Modified Hot laminating machine.
  • Etching liquid.
  • 320 wet sanding paper.
  • Transparent Green spray enamel.
  • scrubbing pads.
  • Stainless & Copper cleaner powder.

AVR USB ISP (AT90S2313 simulation USB)

很多手提電腦已經沒有串口或並口。這種情況下，只能使用USB口的ISP。本製作並不是使用真正的USB晶片，而是用2313類比USB的時序。

MP3stick MP3 Player

The MP3stick is a simple and small portable MP3 player. A microcontroller Atmel AVR ATmega128 is the heart of the circuit. MP3 decoding is done by an VLSI VS1011b decoder IC. A MMC/SD card works as memory medium for MP3 files, playlist files and skin files. The player is designed to draw his power from a LiIo/LiPo battery with 3.6V. a charger cicuit, based on MAX1811, is included. All information will be shown on a Nokia color LCD with 128×128 pixel and 256 colors. The player will work in text-only mode and if a skin file is available, also with nice graphic skins. A docking port allows outside connectivity for serial control signals, audio signals and charger voltage input.
