1T-C2-750 Open Source Arduino module
Posted: Thu Jan 10, 2013 18:12

Most of you already know the 1T-C2-750, a cheap (<800$) DVI/VGA video scaler that can handle 1080p and even tripplehead2go resolutions.
The only thing this device need to be perfect for a lot of Vjs is a fader to fade from channel A to channel B. But there is an option to controll the 1T-C2-750 with a serial rs232 connection.
I built an arduino controller for the 1T-C2-750 that can do this, and it works very good! I had a lot of problems while making this (null modem cable that wasn't a null modem) but now it finally works (after more than a year!). The 1T-C2-750 can change the opacity in 18-56ms.
You need:
-An arduino uno (or similar)
-a fader 10kohm linear
-2 leds and resistors if the leds can't handle the voltage provided by the arduino
-a TTL to RS232 module (I use a cheap one based off the MAX3232 chip from ebay) and an null modem rs232 cable
-5V power supply (I tried 12V but the voltage regulator from the arduino was very very hot!)
-a bunch of wires, soldering iron and a case to built it in
The code is here:

TODO:
- something to change resolutions from the device (dip switch?)
- v2: will propably include a rotary encoder with push button and an LCD screen.
It's also worth mentioning the spark d-fuser: http://sparklive.net and the HD Rabbit from https://www.facebook.com/CarrotVideo?fref=ts
These are a lot nicer then the basic arduino module and offer a lot more functions, the best option if you don't know how to solder or don't want to do the effort for making something like this.
All the pictures of my module (don't mind the bad cuts in the aluminium, I did it with things I had laying around)
