DIY Stirling Engine Kit

It took me about two evenings to assemble the all-metal body, and honestly the satisfying click when each bolt seated into place was half the fun. The integrated flywheel spins up beautifully once you get the heat source positioned, and I actually feel like I understand the mechanics now.

Watching the piston glide smoothly after I got the alignment right was deeply satisfying—definitely a rewarding challenge for anyone who loves tinkering. The all-metal build gives it a nice weight that feels like a real piece of engineering on the desk.

The metal body feels solid and well-machined, and watching it run steadily on just a tea candle is genuinely satisfying. I've already spent a few hours just observing the flywheel spin.
