Build an Arduino EEPROM programmer
Why people recommend it
Ben Eater builds an Arduino Nano programmer for AT28C parallel EEPROMs, using shift registers for the address lines; people build it for their own projects.
Watch for: the Nano runs short of pins for wider buses
In their words
I set up a breadboard memory (EEPROM or similarly-pinned flash) programmer (ala BenEater and many similar sources) using two 74**595s for the first 15 address bits as well as the OE# bit in the MSB spot, and the nano digital outputs for the 8 data bits as well as the WE# (write-enable) bit.
