Hi Jerry here, that "wobbler" is one I built and posted pictures on the antique radio forum. Link should still work. Yes, it is self starting and I did provide to Tony the information from the book I got the plans from. It does drive a carousel and a "generator", an old slot car motor that cranks out a whole .7V DC at an operating speed of the engine for driving the carousel. The output of the gen is feed to a couple "joule thief" boards, each of which can run 3 LEDs at almost 4 V. The motor itself actually has quite a bit of torque but likes to run at fairly high speeds.
The book it came from for plans was "Steam and Sterling Engines you can build" edited by William C. Fitt. Published around 1980. The carousel also drives a music box that plays "Its a small world". At least the little engine now has something to do. I will see if I can post a pic on this thread. Still learning the format used here. If this works out I can post some pictures of the engine itself.
Jerry
Didn't seem to work posting a pic here with a jpeg. Do we need a html format?
