Simple, logic-controlled variable speed fan for fire-fighterbots and other wind-inducing experimentation (beans not required)
Description [Hide]
A fan on a motor by itself isn't amazing; actually quite commonplace. But this tidy little module is different in that it has an additional speed-control circuit that makes it a very handy tinkering tool.
Originally designed to be part of a Keyes fire-fighting robot system (search out a candle & snuff it), it's simply too cool to not have available for other purposes. Heat-sink power disappation. Micro swamp cooling. Helium balloon propulsion. The point is, you feed it 3 to 12 VDC, a pair of CMOS/TTL logic-level direction signals, and you are done!
Specifications:
- 2.5~12VDC input power (6V nominal; recommended)
- 750mA continuous IC drive power
- FF-N20 style DC motor 2~6VDC nominal rated
- Complete with 3" diameter propeller
- Removeable nosecone
- Opposing polarity signal required for operation, although inputs seem to have built-in internal pullup.
- Grounding either input pin activates motor (see IC datasheet for full control specification).
