I'll be the first to admit my enthusiasm for engineering things tends more towards the "what do we have in the junk drawer?" rather than electronics, but I'm stretching out
I'm trying to build an Inspector Gadget
costume for Dragon*Con this year (huge science fiction convention which draws a ton of people, many of whom like to go in costume). As part of the costume, I'm trying to make the helicopter hat thing - I've got the fedora, I've got the lightweight corrugated plastic for the blades, I just have to figure out how to make the thing spin.
Any suggestions for good places to learn about building a simple circuit with a motor? Ideally I want to fit a lightweight motor into the hat, run a battery pack with a switch down one sleeve, and hook the motor up to the blades so I can flip a switch and have the blades turn. They don't have to turn very fast, so I *think* this means I need to find a way to get a low RPM but a high torque motor (not sure if I have a full grasp of how that works), but I do need something powerful enough to get them started from a standstill without burning out.
So yeah, suggestions would be appreciated
I see that eBay has a ton of "hobby motors" for sale for cheap, but I don't know if that's what I'd need or what else I would need to modify them with and make the rest of the setup. (I do have an awesome fedora and trench coat, though, which will go a long way toward making me look like Inspector Gadget even if I don't actually look a thing like him!)
