INFRA-RED "BLASTER"

Bulky, but sticks very well and the clear plastic enclosure acts as a prism, allowing continued use of the original remote without the blaster getting in its way. Good, cheap emitter for Crestron boxes.

Used item PMP mono plastic 3.5mm plug. Red to tip, white to shell, clip off shield. Channels my FIOS hd set top box. Does not lose the first digit like the dual head blaster that comes with the TIVO.

I am trying to wire the infra-red blaster directly on to the front panel of the STB. (I want to hide the STB out of site and run the blaster to the TV. I want to solder in onto the 3 prongs of the existing IR receiver within the unit. This is because the unit does not have a mini PL socket to plug in the blaster. I think the STB has a TSOP21 soldered onto the board. I do not know what pins I should solder the Red White and unshelieded wire to. Any ideas?

For those hacking this thing: Seems to like a bit over 3 volts, applied with positive to the tip and ground to the (middle) ring of the plug. If the plug's sleeve does anything, I can't tell. Snipping into the wire, red is positive and white is ground, with bare wire as the inert sleeve. Seems like the LED has a 45 degree or so visibility.

The plug on these is a stereo plug, not a mono like most standard IR emitters. Since the ground is at the first inner ring, it does not work on most devices that use a mono type jack. TiVos need the mono jack.
