In case you were interested in this "tinySniffer" device being sold on @tindie because you can SSH to it and copy USB pcap files, its capture functionality requires an internet connection because it calls out to a server in China for authorization every time a session is run, and then uploads the pcap files to their website for (seemingly legitimate) remote access.

I contacted the maker to ask about this requirement and was told it was for anti-piracy reasons 🙄 I asked for a refund because this requirement wasn't stated up front and the maker offered for me to keep the device with a partial refund.

For some reason I thought only electrolytic capacitors made during the "capacitor plague" era fail early, but my garage door opener from 2008 died the other day and it just needed a replacement 35v 300uF capacitor on its logic board to bring it back to life. The bad cap didn't bulge or leak though.

The TrackPoint cap and fingerprint reader filler were 3d-printed with flexible TPU filament which required a lot of experimentation with temperature and print settings to get a proper color, flexibility, and as little stringing as possible

The TrackPoint buttons and "i" in the ThinkPad logo were painted with a custom paint I had made to (eventually) match the final TPU prints as close as possible while also matching the actual Dolch logo
