Wi-Fi and OLED Upgrade for MightyOhm Geiger Counter using Adafruit Feather HUZZAH #IoTuesday #AdafruitIO

NewImage

Thanks to Daniel for sharing this upgrade with us – check out more info here!

I assembled my Geiger counter kit from MightyOhm some time ago. It’s a very fun kit and the finished counter looks awesome. Oh, that Geiger-Muller tube sitting on that yellow PCB! I’ve always wanted to modify it somehow and add functionality. Today I realized that an Adafruit Feather sits PERFECTLY where the AAA battery holder normally goes. Doesn’t it look like they belong together? I modified the counter, added a Feather HUZZAH ESP8266 with OLED FeatherWing, and whipped up some code. I’m very happy with the end result. Want to do the same to your kit? Let’s get on with the tutorial.

Adafruit Feather HUZZAH with ESP8266 WiFi: Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

This is the Adafruit Feather HUZZAH ESP8266 – our take on an ‘all-in-one’ ESP8266 WiFi development board with built in USB and battery charging. Its an ESP8266 WiFi module with all the extras you need, ready to rock! Read more.

FeatherWing OLED – 128×32 OLED Add-on For All Feather Boards: A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing OLED: it adds a 128×32 monochrome OLED plus 3 user buttons to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight! Read more.


AIO_Logo_150x150Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the internet. There are certainly a lot of great services out there for datalogging, or communicating with your microcontroller over the web, but these services are either too complicated to get started, or they aren’t particularly fun to use. So, we decided to experiment with our own system, and that is how Adafruit IO got started.

To start, please visit https://io.adafruit.com, and take a look around. You can also visit our comprehensive tutorial located on the Adafruit Learning System.

To make it easy for people to get started using Arduino or ESP8266 we have starter packs with just about everything you may want to connect to the internet, with known-working WiFi modules!
