I was scheduled to teach a course in the local university's life-long learning program, so over the last several weeks I've focused on making some tools for one of the topics I was going to cover: light painting. This is a photo of control boards I worked on this week for two of these tools.
For this project, I decided to make my own printed circuit boards for the first time. At times it was pretty frustrating learning just the right technique to make them come out properly. But in the end, I am pleased with the results, particularly for a first attempt.
As part of the process, the copper covered board is put in an acid bath to etch the traces. It was pretty cool watching that happen; took me back to the days of watching a print emerge on a white piece of paper in the darkroom.
I plan on finishing them this week and taking them to the next
Friday Night Fotogs get together. When I do, I'll post a follow-up with pictures of the completed tool, some build notes and the resulting images.

Comments are welcome but I do moderate them. This is simply to keep things wholesome for general family viewing. By default, comments will be accepted. The few things that will cause a comment to be rejected are:
1. It is too long even though it may be well-written and make interesting points. It's supposed to be a comment, not an essay. If you have that much to say, write a blog article and backlink to me.
2. It is nasty, impolite or uses language that is unacceptable.
3. It includes a a link that has a typo or is broken in some other way.
4. It should have been sent as an e-mail since it is clearly addressed to me and does not appear to have been intended for other readers.
5. It is blatantly self-promotional. This does not mean it can't be self-promotional at all, but it should add some value over an above the marketing.
