Project Overview
- short description: generic infrared transceiver (can be used as a universal tv-off remote, though)
- usability status: beta
- start: December 2007
- end:
- platform: Atmel ATmega48/ATmega168
- initiators: fd0
Abstract
The aim of this project is to create an universal remote-control for emitting and receiving all sorts of codes, e.g. to turn off every TV imaginable.
The idea is based on the famous TV-B-Gone remote.
The current hardware (revision 2) includes an Atmega 168, a USB port, a 2MB Atmel dataflash (for storing all sorts of codes), a learning mechanism (which can detect the correct carrier frequency), four buttons (selecting transmitter and learning mode, enable USB, ...) and of course four powerful infrared LEDs.
All sourcecode is licensed under the GPL.
Current State and Mailing list
The hardware will is available as a construction set. If you would like to be notified or receive general information about the unzapper, you can subscribe to our mailing list using the mailman web interface There is also an archive.
New! Pre-order your unzap construction kit: Webshop
You can find the manual and construction hints for the kit (in German only, at the moment, sorry) at the Wiki page. Write a mail to fd0-AT-lochraster.org if you have a question.
