Sounds like a good idea to me, can never have too much knowledge kicking about on the net, especially when it comes to new comers making something as dangerous as a spinner.

As far as making things like batteries is concerned, is there any real point? I mean, it seems almost as cheap to buy something pre made if you're looking at NiCad/NiMH and if you're going for LiPo then thats your only option, and that seems to be what we will all be looking at as standard in a few years time. Also, I cant see drill batteries lasting very long in a speed 900 drum spinner if thats what you were planning to make packs with. Making wheels/nut inserting is probably a good call though. As for deans mounts, seems a bit on the easy side to me, even for newcomers. Just basically attacking a bit of plastic with a drill and gluing it in really, but saying that, doing those things anyway won't hurt I suppose.

Personally, I wouldn't take anything for granted, start from scratch and go from there, but as there seems to be a big call for wiring diagrams that could maybe just be a file linked through the description of the video that once people have watched it they can print off and take with them as a reference. Could probably be linked along with things like this forum, the stickied thread, rules etc. maybe even suppliers (especially if you're using parts like the Gimson motors)

Also, if you're looking for any parts or a hand to make the robot give me a shout and i'd love to get involved, even as a cameraman if you need it. Don't want it costing you a fortune or taking up all of your time/giving you an excuse if Drumroll still sucks
