Every so often I have to slap myself in the head. I’m surprised that we haven’t covered these things by now. DeWalt’s been selling a LiIon 36 volt battery pack that’s full of the latest A123 cells. These are the same ones that were used in the Killacycle. (I think they’ve got a new batch of cells now).

A while back, [Jeff] sent in a circuit for using multiple packs, leaving the internal BMS in place. [The link is fixed now]

[Robert] sent in a scooter that’s been designed to run these same cells. The custom fabrication and machine work looks fantastic.

[Zach Norman] built this electric bike on a Harley frame. I couldn’t dig up much in the way of details, but the flickr photo set looks good.

[Micheal Raines] built a great looking electric chopper.

In the lightweight category, this hybrid (pedal/electric) bike uses li-poly batteries and a simple motor-tire drive to keep going. via [hacknmod]

Early this morning [tnkgrl] sent in her HSDPA mod for the OQO Model 2. Engadget beat me to it, but it’s a great mod for anyone who visits outside of those handy EVDO areas but want the speed for their UMPC. Living in the middle of nowhere means that I’m stuck with RxTT.

[andrew] built a handy parallel port A/D converter – so far he’s got it logging temps. The parts count is pretty low, depending on an ADC, a 555 and some OP amps.
