Pulso-generateur Pulso-generator Stirling Cycle and Electrical Wave Form

After a original idea from mowerofdoom...Proof of concept to reach the actual wave form from lamina stirling generator.
A smal spring used to prevent piston from colliding in the diaphragm is the only source of noise and
wave deformation. A better video will come with measurement of frequencies and voltage...
In "steady state" without spring the generator con be less noisy than the alcohol burner!!!
Petit montage permettant d'accéder à la forme d'onde produite par un stirling laminaire.
Un petit ressort permettant d'éviter un choc entre le cylindre et le diaphragme reste la seule source de bruit et déforme l'onde par ailleurs pas si loin d'une sinusoïde...
En fonction stabilisé sans choc dans le ressort de sauvegarde le fonctionnement est parfaitement silencieux: on ne peut parfois seulement distinguer que le bruit de la lampe à alcool..

Very nice!

Interesting to see the effect of the spring on the waveform.

What do you think you will try next?

Geoff. :-)

Thanks! I guess I will try to make the same device

with U-Shape tube in order to leave the flame in the same range, to bring the working piston in a vertical position with the option to "tune" the starting position (it is necessary anyway).

In an horizontal frame the torque induced by the magnet's weight increase dramaticaly the drag...

Very nice replication of mowerofdoom's earlier demonstration. Yes good proof of concept, looking forward to the next video with the additional technical parameters.

Well done! regards -Mike

Thanks! I've been working on a new design that would let me change easely the diaphragm diametre but magnet's weight is a real issue: it increases the drag and moreover the "mass" is part of the equation of mouvement: it has to remain as low as possible.

@lecorfec I wonder if you could make the stroke short enough if you could have the coil moving around the magnet, like a loudspeaker. In fact maybe you could use a loudspeaker for the piston.

[lecorfec]

The stroke can be made much shorter but seems to be less powerfull. I guess a loudspeaker would work with small efficiency at 20 Hz even with 1 cm stroke!

I will try to build a device with your configuration (moving coil, fixed magnet).

Thanks for your interest.

[mowerofdoom]

I agree with your findings. Others have suggested also mounting the coil in the piston and using a large magnet outside. This seems like a good idea too.

Keep up the good work!!! G.

Heya! Nice one!

Nice to see the scope images.

I had a lamina running without the steel wool. It may reduce the losses in airflow.

I want to put the magnet inside the piston, and wind the coil around the glass.

Good luck, I will watch your vids!

ma voiture utilise 20 kw mecanique et rejette 60 kw thermique..

je me chauffe avec 20000 kwh thermique/an... en voilà déjà un peu de la chaleur à récupérer...

félicitation, il ne reste qu'à perfectionner encore et encore pour une oscillation avec moins de chaleur, ainsi on pourrait tirer de l'énergie de l'environnement, j'ai vu aussi swingregory, sinfun95, et electric527 et woweofdoom dans mes favoris, c'est très stimulant, merci, tu es parmi les meilleur ! plus c'est simple mieux cela est
