[dombeef] originally built pocketTETRIS as a Father’s Day gift for his Tetris-loving pops. However, having finished the project he’s decided to share it with the universe, and it’s looking rather sweet. He made the game the smallest he could make, with size limitations imposed by a 0.96” OLED display, the coin-cell battery pack, and his desire…
It’s not too exciting that [Joe Grand] has a toothbrush that plays music inside your head. That’s actually a trick that the manufacturer pulled off. It’s that [Joe] gave his toothbrush an SD card slot for music that doesn’t suck. The victim donor hardware for this project is a toothbrush meant for kids called Tooth Tunes.…
Joe published full documentation for the project on his website:
The PCB is shared on OSH Park:
Joe describes the project in this video:
Hear the toothbrush in action:
Small microcontroller board that could run Arduino and help you learn, teach others and make things
The Tinusaur is powered by the Atmel ATtiny85 microcontroller.
We want to bring the cost down to $3 for the basic “lite” boards
and allow more people to be able to get them.
jonmash designed this simple board with two ATTiny processors powered by a micro USB connector.
Micro USB power input to two ATTiny MCU’s. There are two different ATTinys on this board. An ATTiny84 and an ATTiny85. These MCUs are great because they can be used with no additional components. In fact, on this board, the only additional components are some filter capacitors for the power rail and a header for the programmer interface.
I have exposed an array of copper pads for every pin. This makes it easy to add LEDs or to wire to just about any sensor.

Ilya Titov created this adorable, tiny keychain arcade kit:
ATtiny Arcade is a little game made using Atmel Attiny85 microcontroller and an OLED screen. The kit is a great hobby project that requires assembly with a soldering iron.
