- nmz787 is evaluating STM32 microcontrollers for a high-speed EEG acquisition experiment, noting that the chips provide 12-bit ADCs at 5 MSPS and 12-bit DACs up to 15 MHz, allowing oversampling to increase effective resolution (ENOB) and direct integration with on-chip op-amps.

- The group debates the practical value of sampling EEG at MHz rates; superkuh points out that even the fastest cerebellar neurons spike only in the tens-of-kHz range, while muurkha argues that such rates would mostly capture noise when measured through skin electrodes rather than intracellular probes.

- muurkha suggests that the real motivation for ultra-high sampling could be to resolve the detailed shape of individual action potentials, but cautions that 8 000 samples of a 10 kHz spike recorded through surface electrodes will still be dominated by noise.

- Bryan Bishop publishes multiple new transcripts to the diyhpluswiki repository, covering technical talks from TABConf 2022 on topics including ROAST, hac-spec, segwit vbytes misconceptions, silent payments, and braidpool.

- kanzure shares “A Tweaker’s History of the World,” a Substack essay that muurkha notes uses “tweaker” in the amphetamine-culture sense rather than the hardware-hacking sense.

- fenn relays an Elon Musk tweet thread explaining that Starlink is the only communications system still functioning on the Ukraine warfront, that SpaceX has diverted major resources to harden it against Russian attacks, and that the network may still fail under sustained assault.
