I do still have circuit boards available for this project. Ordinarily I’d be happy to assemble another one, but I’m just starting to build a house and my free time is extremely limited. If you review the first couple of posts in this thread...

...you’ll find all the information about it. A link to a Digi-Key shopping cart populated with all of the required components is given on the schematic diagram.
A few notes:
- This is a brownout/reboot preventer only; it’s not a source of emergency power for avionics. For that, the TCW units or a similar DIY setup are a better choice.
- You’ll need a fairly stout soldering iron to successfully solder the large diodes. A soldering gun would be a good idea if you have one. All other components are solderable with normal techniques. The diodes are installed with their ring marking (cathode) facing up.
- It’s a good idea to apply some sort of adhesive around the base of the capacitors and large resistor heatsink to provide mechanical support. I used Shoe Goo on the boards that I assembled.
- I’d recommend using the plastic box as a mounting base for the circuit board and leave the lid off. This will help to keep things cool while the capacitors are charging.
Let me know if you want a PCB. I’ll sell what I have left at my cost: $0.55 ea. + postage and PayPal fee. I’ll include the M2.5 screws needed to mount it in the box.

I am glad to see that there is great interest in the deslumpifier, and that Eric Page has made these available.
I don't intent to sell these. Too many other things to do. BTW: There are BIG Supercaps that help start diesel engines in big trucks, and could in airplanes, too. So it really is industrial technology.
