First board of the year, an automation tool for putting CH55x devices into bootloader mode.

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'll take 'things I didn't care to need to see the inside of' for $100, please.

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.

It's always nice to pick up an old project, and find that past you bothered to label things.

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

Nice to be able to fill a whole print bed. Maybe we need a bigger one though?

Neat: Altium has a realtime trace max current and delay calculator now.

3d printing LEGO-style objects makes for a weird aesthetic. Here's a script for generating icebergs, designed to compliment a LEGO titanic set: https://www.printables.com/model/339137-iceberg-brick

The poor cat says he is soooo hungry
