Featured(tm): reselling my HP3455A DMM to the person I bought it from, a meeting of the HCC computer-club (.nl) Retro-section, reverse-engineering a overflow-valve for a laundry-machine, making quick electronics-prototypes by manually engraving copper-clad PCB, and making an enclosure for the DPS5005 power-supply module.
