jaspreet said:ok tell me one more thing as my motor draws very little current

philba said:Also, the book "Building Robot Drive Trains" by Clark & Owings is excellent and has numerous circuits.
maneuver said:I'm apologize for hijackin a thread here, but my question is in the same area..
These vibramotors spin at aprox. 1000 RPM, what would be the cheapest way to reduce the speed down to 80-90 RPM. I haven't tried yet, but have a suspicion that a simple resistor would drain power as well as speed. And I dont want to buy a expensive PWR, since I dont need to be able to adjust the speed once it's reduced.
jaspreet said:hi
i think mr goodwin is saying the right thing
or the other way may be try lowering the voltage
should try some voltage regulator ic
That seems to be the correct thing to do... unfortunatlyNigel Goodwin said:Use a gearbox, otherwise you won't have enough power to move anything!.

What bugs me is weight, the motor is 10 grams, the batteries are 2x15 grams. The plastic walking plastic toy I'm fitting this into is roughly 50 grams. where will I find a REALLY CHEAP gearbox that dont weight more than all this together?...
