Idea
A peristaltic pump and possible accoutrements for etching boards. The pump could be used to speed up the etching process by displacing spent etchant from the immediate vicinity of the board. The pump could also be used to bubble air through the Copper Chloride etchant that will soon be in play at the space. The air bubbling is an essential process in regenerating the etchant.
A heat exchanger of some kind could be incorporated to speed up the etching further.
Nice things about peristaltic pumps are:
- easy to make
- easy to clean
- easy to estimate flow rate
- look awesome, especially in clear Acrylic
- work could be repurposed to help with the pizza printer
