Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

Is the source code for the $50 debugged and working?
Will a 9.6v ~2000ma/h battery be good? Got a couple of those laying around not being used.
Can I get another 5v voltage regulator and use that for the servo's, cause I'm not too excited spending $15 on a voltage regulator?
Nope. A regular regulator is extremely inefficient and will fry with all the wasted heat.
so you could use a regular linear regulator from a 9v battery for your servos but the "spare" 4 volts will be converted into heat.bolting a heatsink on there will help but it really depends how long your servos will be running for.when i first learned this my regulators were ok while the servos were stationary but they would over heat after less than a minute of movement.trust us here, linear regulators aren't much good for big voltage drops or anything that draws more than a few hundred milli Amps.switching regulators on the other hand have little controllers in them that switch the power on and off at high frequency, then smooth out the output with an inductor and capacitor to get the required voltage.no nasty heat build up and very little wasted power.using a LM2575, an inductor, a diode and 2 capacitors you can build a 1 Amp switching regulator for under $5.http://www.national.com/pf/LM/LM2575.htmlpick a capacitors, diode and inductor that will be able to withstand more than 1A. (i think from memory the datasheet tells you the minimum specs for these components.)once you have one of these built you will be able to convert the power from most batteries to 5 Volts. dunk.
How hard would it be to add or change the source code to a robot with infrared object avoidance?
I've tried avrlib, and don't know how to find source codes. All it gives me is a link to a site.
Am I seriously going to have to wait until the night before the profect is due to get an answer?
If I were to set the photovore off in the class room what would it do? The room's brightly lit.
If I turn off the lights will it follow the beam of a flashlight on the ground in front of it?
QuoteQuoteAm I seriously going to have to wait until the night before the profect is due to get an answer? deal with it. people only post here because they enjoy doing so.if you are not getting a reply, try providing more information or clarifying what you are asking.maybe you are being too vague. or maybe no one knows the answer.for example:
What is L1 in the lm2575 usage diagram? By the datasheet it looks like you wire it up like the lm2575
I also got thisIs it a good one? IT say max 2.4a. at what voltage is that?datasheetarchive, and google doesn' help
so that little thing will run 80 watts(under 36v of course) Shockedso 16amps at 5v would work.
