The Return of No. 83, a Hot Air Engine
vtsteam:
Hi Andrew, that would be ideal. :coffee:
If there was a one day project already posted by someone else, cheap, I'd build it!
If you're in the mood to take on an electronics challenge......?
(Probably no time, I'm guessing, due to landscape, livestock, and guest, infrastructure support :whip: )
vtsteam:
Could be a single accelerometer and a triggered cheap LED panel as a strobe instead of a computer control interface and position sensor.
Thus portable between engines.
Apply in the direction of the axis of interest.
Anybody out there up for that as a project to post here on Madmodder? Come on, you know you can do it! Think of the glory! :lol:

You need some young whiz kid who lives and dreams Arduino not an old codger like mine with an atrophied brain!
vtsteam:
Mine is atrophying, too, plus I'm getting lazy these days. Message to youngsters for rescue sent in a bottle.... :lol:
vtsteam:
New test this morning, 100 watts, 1280 RPM tops after long ramp up, again starting at 650-700 RPM. Same displacer cylinder as before. So that pretty much confirms the consistency of this setup.
Performance appears to be 300 RPM better than it had been before the changes to flywheel, con rod and crank link, when tested at 100 watts.
I'm going to let it cool down and change displacer cylinders to the one with the thinner steel flange and copper end, and test again. :coffee:
