i have never messed with things inside of the darkroom, however, as for liquid etching-related things, i may or may not have seen such things and put them in a milk crate labelled appropriately that is now on the floor of the shop near other labelled milk crates. Also, there is a parts bin near the other labelled parts bins containing nothing but knobs of various shapes and sizes that I created. It also happens to be my favorite parts bin for some unknown reason.<div>

I put a circuitboard etching tank in the darkroom, with an electric heater and an air pump. The goal is for it to be ready anytime you want to etch a board.<br>
<br>
But i can't find the two bottles of Ferric Chloride etchant which were in the dirty shop. There has been a reorganization of the shop recently and I figured the liquid etchant would remain where it was (with all the other sketchy chemicals) but now i can't find it.<br>
<br>
Does anyone know where it went? We need about two bottles to fill the tank in the darkroom. (I did find the nasty old half-bottle which was on the shelves with soldering tools, but i don't want to use it)<br>
<br>
I also need a mechanical timer knob, like the one on a toaster oven or (knob-style) microwave oven, so that it's impossible to accidentally leave the heater or air pump on all night. I don't want one from an actual toaster oven though, because if you turn the knob backwards a little bit it just stays on. And i don't want to take the one from our nice stainless steel Amana microwave because it is going to be repaired soon, and also that timer only runs if it has power.<br>

Thank you for your interest in etching circuitboards at noisebridge. After this equipment is set up and running I will teach a class on making your own circuitboards from scratch at noisebridge.<span class="HOEnZb"><font color="#888888"><br>
