How about a USB stick miner? The current Avalon chip is less than 2.5W, the USB power limit. It's around 275MH/s and could probably be sold for less than $5 in quantity.
Dream on dude 
Ah, huh. Troll.
Ugh, everyone's suddenly an electronics engineer.
Interfacing should be a doddle if they've used something industry standard like SPI or I2C. USB design with an 8bit micro and a simple serial bus could be whacked out in an afternoon. Its so much simpler than a big rig design since power conversion design is mostly done for you.
USB sticks would make efficient mining resource available to everyone. Want a bit more mining power? Just buy the latest mining stick and shove it in your powered usb hub along with the rest.
In fact, fuck it. I'll start a kickstarter project for the mining stick. I just need a spec and a budgetary price from avalon, design the board, start a firmware open source git repo, find a pcb fab, stuffing and testing service and we're away :-)

Combine this with a secure hardware wallet on the stick (someone's already done a secure usb hardware wallet) and you are well on your way to a fully self contained all-in-one bitcoin solution for the masses. Make it easy enough for my grandmother to use, and secure, and you've just made us all millionaires.
