- _Microft 5y agoThey go into the details of etching PCBs (=circuit boards) themselves. I have never created a PCB myself but from what I read at various electronics maker pages on the web, this is not recommended since getting them professionally (and successfully!) made is very cheap nowadays. From what I just saw on JLCPCB [0], getting five pieces of a small two-layer PCB made and shipped to anywhere in the world costs about $10 and takes roughly two weeks.

- serf 5y ago>since getting them professionally (and successfully!) made is very cheap nowadays. this is true. Most DIYers that make their own PCBs are either interested in the near-instant turn-around time for rapid prototyping , or they want to make such an exotic design that it doesn't fit into the workflows allowed by PCB groups like JLCPCB. that said, board making is a hobby unto itself.
- detaro 5y agoNot that unusual in a university context to have the tools to do this available on-site, so it makes some sense they did it that way.
- _Microft 5y agoGood point!
- LinuxBender 5y agoAre there any hobby groups that make kits and open source software for this? Any forums? I would love to have GPR but the software for the commercial devices is expensive. I will probably rent a unit in a few months.
