Cordless toaster robot...

I'm not sure if the world is ready or if the technology even exists but...

Any input on this?

I'm only interested in driving the heating elements for now. Nichrome wire I'd imagine and some kind of voltage/current limiting vitamins to protect the battery? It's gonna draw a lot of juice...

Probably a single slice for now...

Id say its possible with the current technology, wireless power is possible but a little tricky and perhaps hard to get it right

I don't think vitamins are going to help.

Carrot? Apple? Tomato?

Certainly possible. Look at how many cordless toasters WalMart sells. 8)

Maybe start from something like this

and build a 12V battery pack for it?

A USB marshmallow toaster! Yippee!

I was thinking along the lines of a cordless drill battery to run the heating elements but this would add weight so larger motors would be required to achieve the desired speeds which would require larger drive motors which would require larger batteries...

This is really DARPA level stuff but I'm going to give it a try.

The heating wires are pretty much a direct short/load type of deal so I'd have to come up with some wire that would work with a 12V or 16V battery. I'm pretty sure that a standard toaster elements are for 110V AC without any rectification or transformation.

Basically I just need to use a battery to get a matrix of wires red hot without causing the battery to overheat/explode/self-destruct.

Yes that is the problem. You use Nicrome wire, you use as much or little of it to get the resistance you need to get the current you want. https://www.google.co.uk/search?q=nicrome+wire&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a#q=nichrome+wire&hl=en&client=firefox-a&hs=pPf&rls=org.mozilla:en-US:official&prmd=imvns&source=univ&tbm=shop&tbo=u&sa=X&ei=xScMUOfuHsPS0QWhrYnECg&ved=0CGYQrQQ&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=86cb3155a1128e18&biw=1170&bih=748

Recently declassified photo:

I spy some resistors, some capacitors, maybe some diodes and transistors plus the magnetic coil that holds the toast down...

Why I shouldn't be left alone with an Arduino and a toaster...

I figured I'd abandon the actual toasting part but it gets worse.

Much worse...

I hooked a 12V power supply across part of the wire in the toaster and got a healthy glow XD I should've measured the amps it was pulling.

Maybe hack one of those butane curling irons...

I can't explain why I did this...
