Lookin at the Core of the Core Lap Timer
Posted: Tue Sep 05, 2006 1:02 am
Was looking at the Core Timing system I have on loan from Apex and in general just being frustrated about Kyosho’s delay in producing the system, rumored prices of the Kyosho version, and very specifically about the transponders that I ordered, paid, for and have yet to receive. Anyway so I held one of the large transponders up to the light spying the Texas Instrument logo and Tag-It trademark, so I decided to go surfing and it didn’t take long to get a real eye-opener, basically it just doesn’t seem like it would be all that hard to make an RFID timing system, improving on the Core version while your at it.

Looks like all you really need is a simple stand alone database with date/time entries down to 1/100th of a second or better, for example using Access developer. Why even bother with a coded transponder keep it cheep and simple with just the unique id so any old Tag-it transponder with the right frequency would work including the Core transponders, or that old lift ticket hanging off your jacket zipper for that matter.
Especially since the transponders are made to be disposable coming as self adhesive stickers on large rolls. The 24.2 mm diameter round transponder has some distinctly useful possibilities compared to the 22.5 x 38 mm rectangle Core offered as their small size.
