This project was my first UV-Exposure box. But it didn’t work as it should. Therefore I made a new version that works better.
The glass plate with the lamps beneath it.
The timer (Black box with the grey knob on the outside).

This is the first version of my cnc.
The parts are recycled from old printers.
As you can see I had it partially build, but I had to take it back apart because the base plate was crooked. Therefore I started a second version.

I received 2 140VA transformers and decided I’m going to build a safety transformer with them.

I made an aluminium frame to mount the transformers:

I have an old lathe that only turned at 1 speed. I wanted a adjustable speed so I connected it to a frequency controller.
A couple of pictures:
The frequency controller:
The control box with “emergency stop”, right/off/left switch and a potmeter to control the speed.

When the weather is too cold I can’t etch because the etching fluid freezes. So I made a heated etching tank, the heating element is recycled from an old washing machine. It consisted of 2 heating elements, a large 2Kw and a smaller 1Kw, I cut the 2Kw off so it would fit in my tank (and 3Kw would be too much). 1Kw is still a lot off power so I put a dimmer on it. To regulate the temperature I made a temperature controller with a pic16f676. The temperature sensor is a LM35 with heat shrink around it. The display is a 2x7segment display (Datasheet).
The hex file for the pic can be found here: Link.
