Setting up equipment and tools to etch PCB's in-house. As a first experiment we will etch a PCB for the ProjectSpaceAccessControl 1-wire to serial converter setup.

== UV exposure ==

We have salvaged two UV exposure units for double-sided PCB's, combined the two in one. The timer is still a bit flaky, but the vacuum is working. Might need a new top plastic though, as it is a bit dirty.

== Developing ==

For smaller pcb's use one of the small blue containers. We have developing fluid.

== Etching ==

We have a batch of old !Fe3Cl that we can use, but in the long run we will have to revert to less illegal chemicals. There is an etching aquarium with air pump.

== Direct transfer ==

We might also want to experiment with the direct-transfer method, where you print a mirror-image of the design and apply that directly to the copper with an iron, then etch.
