Hacking smart power outlets with a custom adapter #Hacking #3dPrinting #IoT @ncrmnt
Andrew needed to stock up on smart power outlets for his lab. He ordered known WiFi-controlled outlets that have previously contained esp8266, so that they could be flashed with esphome. Instead of a very well-known esp8266 module they had a CB2S module from Tuya. These have Beken BK7231N modules inside and are somewhat supported by an Open Source software stack.
The problem flashing these modules on bulk is – you have to disassemble and solder the leads to the edge connector. It’s okay for a one-time solder job, but is a totally no-go when you have to do it in bulk. So, I scratched my head, fired up SolveSpace and after some trial and error made this weird-looking device.
The idea behind it is pretty simple. Just a bunch of spring-loaded pogo pins and a piece of plastic to hold things in place. No soldering, just attach it and remove once you are done.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
