Design vs Implementation

I’m trying to make a small pogo-pin jig so that I can program the ESP8266’s that make up a lot of projects I play with. Similar to the design in the article “Pogo Pins Make Light Work of IoT Switches”, I want some modules I can clamp over the top of things like the Sonoff Basic R3 or the D1 Mini without soldering on wires or pins.

The one I’m having the most fun with lately is the DETA wall switches - I can’t stand doing fiddly OTA updates - serial flashing my favourite build is just easier. Soldering on a low profile pin header is a pain in the arse, especially if you do it just wrong and the unit won’t go back together. There’s also the fact that there’s a mains-voltage module this faceplate plugs into, and I really don’t want to short on that.

What I need to be able to do is clamp something over the ESP8266 board and connect to the pins temporarily, but sometimes, the design…

The design

Doesn’t translate to the real world.


I know what I did wrong - the 0.5mm pin holes in my design are far too small to translate to the 0.4mm print head, especially when I’m pushing it a little too fast. Something to play with tomorrow, woo!
