When i saw simpleavr’s implementation of usbtiny on attiny45 , i thought it would be cool if i make a kit version of this with a minimal form factor. Then i designed a PCB and sent for first prototype. Later on i thought, if i want to sell this, it would be much cooler ,and more suitable with “Open Source Hardware” concept, if i bring this project one step ahead. So i tried to fit anything extra to the device and this project came out.

The Scoreboard project is now finished and working!
The idea of this project is pretty simple: control a ping-pong electronic scoreboard from an Android bluetooth-enabled device. To do this, I used an ATtiny45 which main function is to display the current scores in a VGA monitor while reading from a bluetooth module UART interface waiting for “commands” that will tell it what to display. The Android device sends the commands via bluetooth, running an application specially designed for this project.
As usual, the whole project is open source, including schematics, AVR firmware and the Android application.

I’m still waiting for my cheap Bluetooth module from China which will serve as an input interface for my scoreboard project. In the meantime, I’ll show you how to convert your ATtiny microcontroller into a Pong game (with no input so far).

Here a small project with an ATtiny45. Currently I was able to write some big characters in a VGA monitor. This is the first part, but the final result will be a bluetooth controlled scoreboard.

AtariPunkConsole attiny45 REMIX…
This is a 16 step (or however many steps you like) built on an attiny45. It only uses 6 parts so it’s a pretty straight forward project. I placed a link to the sketch under the video. Thanks, Rob

This project will show you how to make a holiday star using LEDs, a battery, some resistors, a ATTiny 45 and a MOSFET transistor. You can use them as table decorations, for your desk or around the house.

This project is a wireless temperature and humidity sensor with USB interface based on obdev’s RemoteSensor example and their firmware-only USB implementation. The main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 microcontroller, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. Check details on the link below.

These tiny controller boards are build to provide a quick start for projects with 8 and 20 pin AVR microcontrollers, e.g. ATtiny13, ATtiny45, ATtiny85 and ATtiny2313. They don’t include any fancy stuff, they are just as simple as possible. Eagle schematics are included.
