does anyone still play with these little zip-zap racers or the bit-q infrared racers? I love em cause my kitties get their exercise chasing them around but of course have managed to mangle a few,, which has led me to attempting repairs and also doing some hacks for automated control (so i don't have to sit their controlling it, and can easily deploy more than one at a time.)--I have some basic questions about both types and am hoping someone knows alot about these two types in particular?

- For instance I'm trying to find out the exact battery specs for the bit q (I believe the zipzaps are 1.2v ~120mA)

- I really need to find the rx and tx schematic(ZZ) if possible cause trying to map it out from such a tiny baord has been lame, and a datasheet for the realtek rx1/tx1 or clones,, been having a heck of a time finding info about these IC's for some reason!! mostly need info about how much of the radio block is integrated into the IC...

- I'm also trying to find out the exact part number for the bit-q IR-module-- I know it is one of those integrated devices that takes care of the de-mod and some basic filtering- and the case indicates its freq (I think) but haven't found any results after doing some google searches of the numbers on part-package,, manufacturer logo looks like a forward tilted HL? #s, 138 // BB17 // 0305

anyone able to shed some light? apologies in advance if this is just the wrong darn place to post about these lil racers... cheers, jd

if you want to do automatic control, cats aren't the most intelligent creatures, so you could have one controller with the up and right buttons stuck down, and the cars would drive in little circles

and the batteries i think are supercapacitors, so are charged to whatever voltage the handset charges them at.
