OLED name badge with rechargeable LiPo cell


Here’s a project that let [Rick Pannen] try his hand with an OLED display and a rechargeable power source. He calls it OLEDuino which is a mashup of the display type and the Arduino compatible chip running the whole thing. He figures it will serve nicely as a geeky name badge but also ported a Breakout type game to play when he’s bored.

The project is an inexpensive way to attempt a more permanent trinket than simply using Arduino and a breadboard. [Rick] sourced the OLED display and USB LiPo charging cable on eBay. The ATmega328 hiding below the display is being driven from the 3.7V LiPo cell without any power regulation. The four buttons at the bottom provide the only user input but it should be more than enough for a few simple tricks.

Head over to his code repo for a bit more information. The schematic and board are both Eagle files. We generated an image of the schematic and embedded it after the break if you want to take a quick look at how simple the hardware really is.

  1. stack it all and move button closer to oled, 3d print a case for it.

    I want to do this with a efficient cortex-m4f or cortex-a 3xxx just to mess with low level armv7 coding and hardware.

    1. I definitely like this. Just needs a little more refinement.

      I’ve got a tiny [2″x1″] development platform I’m working with all of the recharging, USB-serial, mic, speaker, joystick, etc built-in. It’s a work in progress. I’ve also got a stripped-down version that just functions as oscilloscope / spectrum analyzer for a wearable pendant [just waiting for the boards].
