I want to control the IR remote receiver on my digital camera from a greater distance than my IR restricts me to. I want to use RF to control an IR emitter to my camera. I can already do this to some extent with a big, clumsy setup--but it requires a long 110 volt extension cord to power the RF receiver/IR transmitter. Surely there is such a thing as a small portable power pack to run a small portable RF receiver/IR transmitter??? I have put a solution together with BIG pieces, I only need to refine what I am doing in order to make this more user friendly. Any help would be appreciated. Thanks

Kip,

I don't know of any ready made off the shelf stuff to do what you want. If you're willing to do a little hacking, it wouldn't be hard at all. Here's what I'd do: Harvest the RF receiver from an X-10 TM751. You should be able to run that on a 9V battery. Take the output from RF detector and connect it to the input of a Firestick II, logic level to 38KHz IR converter. Next you'll need to get hold of an X-10 UR-24(?) 8-in-1 learning remote. Pop open the case and snip the "enable" line going to the RF board. That will make it always send RF. Teach the 8-in-1, the IR commands for your digital camera, using the camera's original remote. Now, when you press the appropriate key on the 8-in-1, it'll send the IR command via RF. The TM751's RF receiver will convert the RF back to baseband and the Firestick II, will send it out as properly modulated 38KHz IR and voila, the camera fires. You might need to tweak the TM751's receiver a bit to get it to quiet down and not flood the Firestick with data.

Most of the X10 receivers drop the voltage internally on the circuit board. I am modifying a PAT01 to work on 24 Volts so I know it can be done. You need to find, or draw a schematic on the Powermid and see what you can do.

I have a schematic of a Powermid, if anyone needs it.

You can get IR-kit DSC from smarthome.com - it has outer AD/DC adapter, that can be disconnected
