DIY TiVo IR Blaster

Posted August 29, 2012 by Chris

“The IR blaster that came with our TiVo was lost long ago, in a time when no unnecessary electrical-optical-electrical sillyness was required for it to function. Rather than spend $3 on eBay and wait a week to get a replacement, I decided to make one out of spare parts in my junk bin.”

    My dad uses something like this for our TiVo, except with an optoisolator instead of an IR diode. It actually uses the TiVo as the transmitting end, and the digital cable box as the receiver, allowing the TiVo to change the channel coming in on the cable.
