Accidentally opened YouTube logged out, which normally shows me Vile Shit but this time instead showed me "14 BANNED GADGETS YOU STILL CAN BUY ON AMAZON", a video cataloguing mostly some pentesting and gray-hat security tools, as well as a couple anodyne devices (the Pocketchip, really?) and one clearly illegal car mod. (The video fails at any point to back up the claim that any of these devices are either "banned" or "still available on amazon", though the GSM jammer probably is legitimately illegal to sell in the US.)
Anyway what caught my eye was the "DSTIKE deauther watch", a smartwatch sold direct by a guy in China who designs and possibly handmakes them, which performs simple attacks on WiFi networks in the vicinity. Although pentesting WiFi networks is not a use case I have (and the watch is probably less useful anyway for that usecase than the "Flipper Zero" which was also in the video), this did interest me because the thing has a screen, a 1D clickwheel and a fully Arduino-reprogrammable ESP8266 (a WiFi chip with an onboard CPU— "Xtensa" ISA, which I'm not familiar with). In other words this is a $60 wifi-enabled minimal hackable watch platform. It seems likely there's a better hackable smartwatch somewhere I'm not familiar with, but it would be very amusing to me if it turns out the current best way to do a custom Internet smartwatch project is to repurpose hacking tools.
(The DSTIKE site also offers a "v4" version which has an antenna and Atmega32u4 USB output, but it looks a little more awkward to actually wear on the wrist.)
