61301RE: Cheapo linear actuator using a pager motor?
- Feb 6, 2014
Yeah, the spring is a problem. However, I have made direct-driven leadscrews with hobby motors and 6-32 threaded rod. I definitely wouldn't classify them as "easy" to build, at least without a lathe. But they are fairly cheap.
The string-twisty actuator looks like it could be a good compromise.
