flyback cooling

[DaveWM]

I used some very thin copper clad (both sided) material to fab up the cage. It was very easy as the material would bend sharply and you can burnish in a nice 90 degree bend. holes and cut outs are easy with some curved small scissors.

I folded in the tops about 1/2 inch and lap seamed with solder to hold its shape.

I still need to fab up a top, but will wait on that until I test it out.

cut a large round opening that puts the fan right at the side of the fly, used some silicone dabs in the corner of the fan to hold it in place, spaced up the fan just a bit from the copper (I am hoping that will keep the vibes from the fan from being amplified by the thin copper).

I will take some pics tomorrow after the silicone has a chance to setup. I only have about 1 hr total fab time into it so if it does not work its no big loss.

I will still have to make up a DC power supply, I think the filaments would be fine with a 1/2 wave and a 100uf filter cap.
