we think this might be helpful an is a joy to watch: analog recording workflow with a neve 81xx-series console and the melvins being recorded. sylvia massy explains the characteristics and awesome features of this early-70ies vintage neve console perfectly.

for those who haven't been folllowing on chaos.social or facebook (I understand, believe me!). We have been working on our own analog audio designs, from SMT PCBs, soldering & modding clones of classic console pre-amps, EQs and compressors to modding existing gear/kits. check secondorderharmonics.eu

too much text apparently I've been comparing TRMS Multimeters expensively bought (years ago) and new cheap Chinese, very positively surprised: chaos.social/@azet/115573...

absolutely positively surprised about the €35-€40 digital smart multimeter with live wire detection, temperature, Laser humidity sensor and the extremely well working auto function ...

ever wondered how to design directed energy weapons with OTC components, cheap china parts? and a custom PCB that we let the MuskAI design & we verify. why not add industrial/rugged components, burst, AM, FM, freq hopping & a epaper status display?

there's yet another stupid proposal - this time for debugging not middle box vendors - in the TLS working group to standardize key export among other encrypted traffic details. please don't. cryptolibs provide these & we all know how to handle wireshark.
