I tried using a buck converter rated for 8A (12A max) with the voltage set at 7V, but I think the sudden load fluctuation caused the converter to break because now I can no longer adjust the output voltage to any other quantity than the input voltage

We had similar problems with regulating our power supply with the Buck converter blowing out - seems like the DROK ones aren't all that reliable. We used a 5v voltage regulator like the one shown here https://www.adafruit.com/product/2164 and wired it together through a breadboard. I'm sure you can solder too, and a quick google search pulls up similar products for 7v: http://www.mouser.com/ProductDetail/ROH ... AvOz8P8HAQ. I suppose you'll have to find one that fits your current draw; our 5v one heated up a lot but it still worked.

Thanks! Ill try it!

What do you guys think top 3 National scores will be? Also what do you think is the width of the thinnest vehicle at nationals?

I know somebody who has a very successful vehicle which is around 4cm thick (I think they go for a 6-7 cm bonus). Expecting them to win first with about -18 or -19 score, and 2nd and 3rd to be around -15 or -16.

I think 1st will be -16 or -15 ish. In practice, there are just too many variables and interpolation will take away some accuracy. I think 6th will be around -11 or -12

I know a guy who knows a guy who knows another guy who is getting a 2cm bonus.

Smashing cans is pretty risky though. Hope I get to see it

Oh yeah I know who you're talking about. However they do it by smashing the cans, which, as windu mentioned, is risky and depends on the cans' weight. Also the team you're talking about isn't getting very good accuracy, so scores around -16 at best.

Is this Mentor? For the record, at OH states they were no longer the only team splitting the cans.

How many teams in Ohio split through the cans and how successful were they?
