The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. That is, it allows you to program the microcontrollers on other boards you make, using nothing but a USB cable and 6-pin IDC to 6-pin IDC cable. It’s based on the USBtiny and V-USB firmwares, which allow the ATtiny44 to […]

Slaveflash-trigger for digital cameras with Attiny24

When flashing with digital compact cameras, the camera usually uses several small flashes before making the actual picture. This is o.k. if the built-in flash is the only flash you have, but if you want to use an external second flash you have a problem: The second flash, also called slave-flash, fires if the master-flash

Buggy – A Crafty Programmable LED Creature using Microcontroller Atmel Attiny44v

Buggy is a programmable LED craft project using a homemade, single-sided, PCB board, and a programmable AVR Attiny44v microcontroller. Buggy has two bi-colored LED eyes and can sense visible and IR light and emit sounds using a piezo speaker. Not counting the board, there is about $8 USD in parts per bug. I designed this
