DIY EEPROM programmer

   
Hardwarethe blog post DIY EEPROM programmer describes how you can use an Arduino Mega and a few external components to program EEPROMs.

Also read the Simple EEPROM Programmer revisited update. From the post "You need single-row pin headers, double-row pin-headers, a ZIF socket, a red LED, a green LED, and two 470-ohm resistors."

But - the ATmega1280 has 128K flash, 8K SRAM and 4K EEPROM, this limits how large parts of of a device it can program in "one go" so to speak. The ATmega 2560 has 256K flash, SARM and EEPROM is the same.

Others: the 28Cxxx EEPROM Programmer is OSHW, boards can be ordered from OSH Park. The downside is that it uses a Microchip PIC18F, adn requires MPLAB tools to build.
