TuxCon Kitty TV BGone Mod Irdroid

This year’s (2017) TuxCon open source Linux conference took place in Plovdiv, Bulgaria. On the second day of this gathering ( the Workshop day) we all got a free and open source soldering Kit – the TuxCon Kitty conference badge (Thank you Olimex). The kit included a Atmel Attiny85 microcontroller, the TuxCon kitty pcb a buzzer two leds (the Kitty eye’s) one battery, battery holder and several resistors, capacitors and diodes.

I was on the conference with my son and we had a lot of fun assembling the kits. The kid was really exited to make his own toy and play with the other kids, attending the conference. Weeks after the conference I found the TuxCon kitty badge in my drawer and decide to make something cool with the Kitty badge – To turn it into a TuxCon Kitty TV BGone Mod Irdroid – To make it possible to switch ON/OFF any television by simply replacing several components from the existing design. The software that I have used simply sends a bunch of TV Power (ON/OFF) infrared commands in a loop.

Hardware Mod:

  1. Remove / desolder R1,R2, R3 and R4

  2. Solder 22 Ohm 0805 resistor to R1

  3. Remove Led1 and solder IR LED (TSAL6200)

  4. Desolder D1 and solder a micro switch/button in its place


The TuxCon Kitty badge is compatible with Arduino and comes pre-programmed with a bootloader and default code. I have programmed a new TuxCon Kitty BGone firmware using a STK500 programmer and desoldering/soldering the MCU (I havent yet found a way to write HEX using the Arduino IDE / the default bootloader in ATTiny85 that shipped with the badge) . I have used a Tiny85 code by Mitch Altman + Limor Fried (Adafruit Industries)
