This project is based in 99% on Ben Eater's EEPROM programmer. So all credits go to him for this wonderful invention. This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar ...

An Arduino Nano sketch and schematic for an Atmel 28cx programmer. The schematic started out only targeting 8kx8 chips (rev. A) but has been updated to connect all address lines for the 28cx series ...

[Daumemo] likes experimenting with DIY electronics, and like many people, eventually ran across an AVR microcontroller with a Unified Program and Debug Interface (UPDI). One option is of course to ...

Arduino Nano with ATmega328P is available in two variants: "ATmega328P" and the older "ATmega328P (Old Bootloader)". The newer variant uses an optimized bootloader which has double upload transfer ...

What do you do when your trusty, 45 year old calculator finally needs to be retired? If you’re a programmer with a knack for making things — like Simon Boak — you custom build a replacement. This is ...

Ok, we’ll come clean. [Design Build Destroy] didn’t really add any memory to his Arduino Nano. But he did get about 1.5K more program space when compared to the stock setup. The trick? On some Nano ...
