Hi,
i got one of these small Solar thingies from a friend as a gift and tested it for this. It works great for the Trackclip Pro to make it "wireless"...Tried it to recharge my mobilephone with it but it doesn`t work, so took it for my Trackclippro and G930 to make the whole thing "wireless".
Something like this, there are alot of those things around to buy, the cheapest ones should do the job great for ur purpose:

Works great even in a completely dark room with only ur Monitor as a light source...wondered myself why, but it still produces energy to keep it working...
U even don`t need the Solarcells to look into the Lightsource, my one is looking straight up and still works fine...
It`s small and easy fix on the G930...
- its cheap
- no recharging because of Solar
- works even with minimum light and produces more then enough energy
- not heavy
- no batteries needed because the light is ur energy source
- Works perfectly for the Trackclip pro
Just a hind, give it a try, it´s maybe the cheapest try to get all this to work how u want - "wireless"...
Cheers BBS
