I found a wonderful little tutorial on a better way of applying the dry photoresist film: http://members.optusnet.com.au/eseychell/index.html Following it, I got much better results; I little wrinkling on both sides, but I was able to (mostly) work around it. I should be able to avoid that next time. The 6pt fonts all showed up well; [...]

Not sure if want…
This is the result of the third attempt to get the photoresistive film applied decently (very difficult) and gets some boards going. At quandrants 2,3, and 4, I have a test board for an RF switch I am using for my Senior Design project; in the first quandrant are 4 adapter boards for an accelerometer [...]
Ultraviolet Exposure Light Box with PIC16F54 Timer
Now Listening: Metamatics - A New EndTop of the box with a ruler for scale. I just finished designing and building a (12.5″)x(12.5″)x(6″) ultraviolet light box with a pic16f54 microcontroller programmed as a timer for the exposure. It was made mostly to be a UV light source for exposing photosensitive film used as an etch-resist in the process of making printed [...]
Xmas RGB LED PIC Toy Gift Project
Now Listening: The Black Dog - CycleI wanted to make something special for people I know to give as Xmas gifts this year, so I went into engineering mode and came up with something fairly simple, but still fun. Admittedly, this isn’t for everyone, but I don’t care; if they can’t at least pretend to appreciate my hard work and creativity, [...]
First Module: 12-Stage Phase Shifter
Now Listening: Squarepusher - Schizm Track #2 MixInstalled Phase Shifter module, not yet screwed into mounting rails. I have finally built my first module, a 12-Stage Phase Shifter, mostly based on this MFOS design. I will be updating this post with more details sometime soon.
