Feeling a bit left out because he didn’t have a PICAXE on hand, [Rob Miles] decided to port the Luna Mod code so that it would work on an AVR chip. He chose to build his around an ATtiny45, but also ...

[Vassilis Papanikolaou] took a good thing and made it better with some design upgrades to this AVR based signal generator. We looked at version 1.0 of this tool back in 2006 and since then it saw an ...

This low-cost project aims to develop an open-source AVR USBtinyISP programmer with SPI interface that is built around the ATtiny2313 AVR microcontroller. The project has been tested with the ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...

The project is a second version of the AVR signal generator where it uses a single sided PCB for simplification while containing both offset and amplitude controls. This version of DDS signal ...
