URGENT!! Need OI power brick specs for 7AM demo tomorrow!!!

Originally posted by dlavery I haven't had a chance to actually measure the current pulled by the OI. But I know that when we tried to use a 1 Amp supply (over the years, we have lost four of our OI and RC power supplies, [...] Somewhere between (1200ma) and 1500 mA you cross a threshold, and at 1500 mA it works just fine.

OK. Based on your previous post re: the wiring, I ran a test. YES, it comes up on my lab supply. Hmmm... "At rest" with the RF connected, it's running about 400ma... OK, I believe you when you say you toased a few small bricks. <shuffles through inventory & pulls out a meter to check some bricks>

Hmmm.. OK. I've got a 1500ma 12V brick here with the right connector and polarity. <verifies it on the meter, then jacks it in> Success! We're up and running! Thanks!

Originally posted by dlavery What I learned from all this is that I want to sit down with someone who really understand RF systems, and see if we can cobble together a really cool signal amplifier that we can run off my 100 Amp supply. Then we will sit back and drive our FIRST robot from the next state...

Yea right, and pull in the FCC from the next state, too when you jam the shared airspace for a few hundred miles... <chuckle>

Thanks for the help! When we get a chance (after the next contest), I'll have to set up a lab test on the new kit to see what that EWave is pulling. (THIS copy is borrowed, and will have to go back to the original team. THAT's why I wanted to be sure about the power before tried anything!)
