Have you ever seen an AA alkaline do this?
You could build and install an AVR-powered temperature monitor in the battery case... make it beep if a cell gets warm. The automatic solution? :)

Arrow to buy NuHorizons
Well, the electrons and photons that describe your order do have to travel very far to get to the states. I bet they are unionized too by now. :)

ASK/FSK modules - Is an antenna mandatory?
Yes, you need antennas to send radio waves (with any form of reliability). That's the whole point. The circuit should be designed so that it emitts close to nothing, channeling...

AC Audio Amp Suggestions?
Indeed, Mr. Gardner has said the magic words, without speaking them. Details!

SMPS boost converter, want more power
And the math for it is even on wikipedia - and yes, the equations can be trusted, they're the same I used when taking a course in SMPS's. Sit down, take your time, and understand...

Graphics LCD, Flex Tail, "Hot Bar" soldering...
I've never come in contact with that kind of connector, but from what I understand it's quite similar to the "flexible strips" on LCD's you mention, JC. That means they'll be...

DC Motor Regenerative issue
tlucas: There are circuit versions of them that do. However, if you look at a "standard" buck, there's a diode in the current path, which means it'll only work in one direction....

DC Motor Regenerative issue
Oh, just read the 26V requirement again, forgot it along the way. Yes, that'll be a problem, that's pretty tight considering the power we're discussing (up to 100W braking, as far...

DC Motor Regenerative issue
And my workmate just walked by and we started talking... as usual, this got a bit over the top, but this is what we came up with - complete control over regeneration. Q5 controls...

DC Motor Regenerative issue
ford2go: The problem with a series diode is that the motor is "generating" energy, which will have nowhere to go. That will cause the voltage to increase until a path forms...

What's the purpose of the ground plane?
Only problem with watching on a scope is that you're putting a load on the line, which may or may not be significant... I.e. it'll work when the scope's there, but once you remove...

I love 8-bit AVR but need more power!
I'm using IAR at the moment, and it's not the greatest, editor-wise. It's probably possible to move the editing part out easily... actually, why wouldn't it be possible to just do...
