• Make a Sound Card with PCM2702
• ATmega48/88/168 Development Board

This is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM… These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.

GALBlast Version 1.6

GALBlast Version 1.6

GALBlast is a hobbyist grade GAL® programmer that connects to the parallel printer port of your PC. It will program fusemaps stored in standard JEDEC files into GAL chips 16V8/A/B/C/D/Z/ZD, 18V10/B, 20V8/A/B/Z, 20RA10/B, 20XV10/B, 22V10/B/C/Z (no 22CV10), 26CV12/B, 6001/B and 6002B manufactured by Lattice, National Semiconductors and STMicrosystems. It can not be used to program AMD/Vantis PALC/PALCE, Cypress PALCE, ICT PEEL or Atmel ATF chips.

It is a hobbyist grade programmer because the PCB will not offer zero-insertion-force sockets and is therefore not well suited to programming large volumes of chips, is targeted to DIL chips and will require an adaptor for PLCC chips, and because the system is not certified by the chip manufacturers. It is not even based on manufacturer's documentation. Therefore they will not guarantee that their chips will be properly programmed using this circuit, and furthermore, will stay programmed, and neither will I. But the circuit is easy to build, using only very few cheap and easily available components, and has been used a thousand times without problems. And to the best of it it's free.
