Hi;

I know you made your circuit a long time ago but I need the spice models MJD112G and MJD117G. Could you add it in the comment

thanks

Hi Michael,

It's great seeing this project taking shape! I guess pulse inputs won't matter much since the intended use-case is to drive it with a sine wave, but it's awesome that it could be used for many purposes.

Also, it's nice seeing the assembly process, I was building a home-made stencil printer but it's been on hold for ages : ( I have most of the metal parts so I should really finish it.

From the photo, it looks like a neat design.. it's using two leadscrews to adjust to pull on the stencil?

Very neat that the PCB thickness is handled by the base screws, I hadn't thought of that idea... I was going for a method where PCB shim material would be used to raise the stencil to the right height.

Hi Michael,

Thanks for taking the time to share your process. It was very interesting to read. I hope the faster transistors make the difference.
