The built-in calibration project on the Prusa SL1S is neat- it prints a model with 8 different exposure settings simultaneously, allowing you to pick the best one: https://help.prusa3d.com/article/resin-calibration-sl1-sl1s_112182 If I followed their advice for longer expose, this might have worked in the first round
Nice part: STM's USBDF01W5 includes both ESD diodes and an RC EMI filter in a SOT23 package. Very convenient that it has the same footprint as common ESD-only parts ;-) https://www.st.com/en/protections-and-emi-filters/usbdf.html
Logic 1 does support this, but I'd much rather use 2 these days.
The @saleae Logic 2 software is really nice, but the remote control API didn't have an obvious way to just start a capture using the current settings. Fortunately you can do it yourself by using a GUI automation tool to poke at the right part of its guts: https://gist.github.com/cibomahto/3c47e7b06622aad732cbea4ac11900c4
Protip: You can buy new logic analyzer probes to replace your old worn out ones. I recommend replacing them at least every every... 10 years now I guess? https://eur.saleae.com/collections/accessories/products/wire-harness-97
I was wondering how many solutions there were to this 'scramble squares' cat puzzle my great Aunt gave me, so I wrote a solver for it: https://gist.github.com/cibomahto/31e0ec014bedcd39242265e333535809 . The answer seems to be two unique solutions.
I'm attempting to extrapolate radiated emissions from common mode current measurements. Here's a measurement of a USB memory stick when idle, and when transferring data. So far the measurements don't seem to correlate well to known emissions measurements, but maybe it's helpful for troubleshooting noise sources.
Here's a printable plastic stand to hold your RF current probe in a fixed position (why don't the probes come with something like this?): https://www.printables.com/model/307119-cable-support-for-rf-current-probe
