I have an idea what you can do with the gearmotors!
you can apply for the free Solidworks demo and get the 128mb flash drive free with it, and make a conveyor belt in front of your usb port, and between the conveyor belt and the usb it is a spinning plate, so when the flash drive gets on it, it spinns 180 degrees and gets inserted into the usb! then of course you would have to put it the wrong way on the conveyor belt, but its still pretty cool!
or, you could check if you have 2 identical gearmotors and make a robotic base out of it, im trying to do that, but the problem is that i never find 2 identical gearmotors...
if you ever run out of ideas (this is what i do) i think of robotics, or the subject i want to get ideas to, right before i go to sleep, and i have this little sketch book close to my bed, so when i wake up, i go back to half sleep, and i think of robotics, then i dream of robotics and get these crazy ideas. IMPORTANT: you have to draw/write your ideas as soon as possible, because after about one hour you have forgot half of them, and at the end of the day you have forgotten all, and if you dreamt an everyday situation, the next time that situation happens, you get this crazy deja vu experience. its real freaky!
