Hy guys,
By far, the best site I've found on the topic is here:
http://nordicgroup.us/s78/
My plan is to get the 20W eagle eye driving lights, use one of those. I'm also going to order the $44 charger (I considered making one and I actually even ordered samples of some Maxim ICs). Two 10xAA holders, put connectors on those guys that match the connector going into the battery charger. Make a Y cable so you can use both battery packs, or just one. Mount one of the 20W Eagle Eye lights up front, get a seat bag to put the battery pack(s) and switch in, put some velcro on the back of the seat bag (flexibility), and attach a xenon strobe by velcro. Very simple and it should work well. You might want to re-consider using AAs because they are so much cheaper - you can find 10 packs of 2000mAh AA's for $9 online. Check out that page, it's a really great page.
Also, if you need discounty type electronic components, a source he doesnt name on that page is jameco.com. Radioshack is usually a rip-off, try to find a real electronics store near you.
Good luck, I'll try to post pictures if I ever can get this going in the next couple of months.
