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. The modified servo is a HITEC HS-300, but the hack should work equally on any servo. The video shows preliminary testing of the linear actuator and general instructions on how to replicate it. Detailed assembly instructions and additional hacks can be found at:
