Heh. i built myself a pogo isp header last year using some of your pogo-pins and a pair of ISP Breakout/converter boards. i made it to upgrade the firmware of the large serial LCD screen backpack which really needed the upgrade (was not one of the better works). its nice to see a old idea made into a kit. i still use mine to save on header pins…i go trough them like crazy!
awesome that you are carrying a kit for those.that haven’t tought of it. its very easy to make a pogo header by using 2 PCBs for allignement which you do.
