[Juan] sent us his writeup of a microcomputer he built using an Arduino UNO (AVR ATmega328p) and some off-board SRAM. This one’s truly minimalistic. Have a look at the schematics (PDF). There’s an ...

The circuit was based on the use of Arduino AVR to build a high voltage programmer which can be used to fix pesky fuses. The circuit was based on the use of Arduino AVR to build a high voltage ...

Joining the vendor’s 32-pin picoPower AVR microcontroller family, the ATmega48P, ATmega88P, ATmega168P, and ATmega328P devices have 4, 8, 16, and 32 kbytes of flash memory, respectively, providing a ...

We’ve all got projects kicking around that we haven’t had time to document for our own purposes, let alone expose to the blinding light of the Internet. There are only so many hours in a day, and ...
