Hack your servo V1.00 - Turn your servo into a powerful linear actuator and lift 10kg!
Provided you have the tools and the servo you can built this for under a couple of bucks. The actuator extends with a rate of about 50mm/min. It is rather slow but very powerful. Watch the video where the small actuator lifts 10kg vertically.
how to make it? info can be found here:
A possible application? have a look here:)
I look forward for your comments!
