Hackaday Prize Entry: WiFi ePaper

[Frank Buss] designed an electronic version of a sticky note: a WiFi enabled, solar-powered ePaper, with magnets embedded in the casing. It’s based on the new ESP32, and the idea is that you can update it via your smart-phone or over the internet via a cloud app to show any message you want. Being an…

ESP8266 Pogo Jig Programming Board

We like the novel orientation of pogo pins that Wing Tang Wong used in this board design:

This is a board designed to take a WeMos D1 Mini board(with the ESP module removed) and use it as a USB interface with built-in reset/flash functionality for bare ESP8266 modules similar to the ESP-12 units.

Onion Omega2 Breakout

Onion Omega2 Breakout

My Omega2 Onion shield, using a AMS1117 for 3.3V and CH340G for USB to serial. Kind of ugly soldering here as I didn’t have a tip for the syringe to dispense solder paste, so I just smeared it all over and hoped it reflowed well. It kind of did, but I had a solder blob short on pin 14 +15 on the CH340G, so I just lifted those two legs off the board. I was so eager to get this board tested that I forgot to check that I had these 2mm pin headers. I had just enough to get this thing tested. Time to order more 🙂

Order from OSH Park

Simple breakout board using the dirt cheap IC’s CH340G ($0.30/each on ebay) for Serial and a AMS1117-3.3 ($0.025/each) for power. Breaks out all pins from 2mm to 2.54mm headers. Plugs nicely into two small breadboards for prototyping.
