I take my hat off to you sir. I was spell-bound watching your solutions to engineering problems so that you could make use of discarded materials (e.g. old hard drives). I am curious what the phase relationship between the displacer and the drive piston. Very impressive engineering. Thank you for sharing.
Thank you for visiting. The phase relationship is that the displacer rises at 30 degrees before reaching bottom dead center, and the displacer falls at 120 degrees before reaching top dead center. (7:45)
Congratulations, a perfect finish for your engine and it works very well. I also found the materials you used easy to access interesting. Leandro Wagner.

Hello Mr. Yattemita. I found your video and design very inspirational. I was impressed by the minimalist approach and the very clever use of epoxy. I am thinking about adapting some of your ideas and modifying them by replacing the aluminum posts with 3d printed components for my design. At first I was very excited because at first I thought the top and bottom where CD or DVD's (of which I have many hundreds), but then I realized from reading the many comments that those are made from aluminum that have a much higher heat conductivity than polycarbonate. Are those disks from a hard drive? For my design I plan to use a CD for the flywheel, since I have many of those. I found you piston design very interesting as well. At first I considered using to a glass tube with graphite piston, but your approach is making me re-think that there are other possibilities. Have you add issues with the piston leaking over time? Is there any lubrication on the piston/cylinder? ありがとうございました
Thank you for visiting. Those discs are from the hard drive. Please note that some hard disks are made of glass. For now, the piston does not leak. No lubricant is used on the piston / cylinder.
Thank you for your wonderful design. I built 1 Sterling engine. It ran, but it was not as good as yours. I will be building one with your design. Can 1mm aluminum be used instead of hard drive discs? Thank you for inspiring many to build Stirling's. Ed
I like the idea using the magnets. I dislike trying to make another good performing low-displacement sealed compliance from common materials. Good job 👍
Is this able to reverse because the phase angle between the displacer and drive-piston is loosely coupled via magnet and therefore only determined at runtime? Very clever!
Todos os japoneses são pacientes, inteligentes e habilidosos assim como o senhor !? Essa é a ideia que fica. Porque o ocidental vai dizer que isso é truque !! He he.
It wouldn’t. The oscillation of the piston and displacer need to be 180 degrees out of phase. However the addition of a weak spring above the displacer would allow the engine to run in any orientation.
Excellent interesting idea , tutorial and job! Please can you mention the specifications and dimensions of the two neodymium magnets. In all reactions and answers I cannot find them. Best regards from Holland, Stirlingmodels, Huib Visser.

Hard disc is made from aluminum. The gap between the power piston and the cylinder is not measured, but it is made to move lightly with little air leakage. The gap between the displacer piston and the plastic bottle ring is about 5 mm. Thank you for watching.

Magnets repelling or attracting each other?
The magnet of the piston and the magnet of the displacer are attached so as to attract each other.
The behavior is as follows:
When the piston goes down, the displacer is attracted and goes up. Next, when the piston moves up, the distance between the displacer and the piston increases, and the magnetic force weakens the attractive force. When this attractive force becomes smaller than the weight of the displacer, the displacer falls down. Repeat this.
