Gerd Müller's ESP8266-Powered CoinThing Puts Easy Cryptocurrency Tracking on Your Desk

Linked to CoinGecko, the CoinThing can chart the value of any one of over 5,000 cryptocurrencies with automatic updates over Wi-Fi.

Maker Gerd Müller has launched a desk-based tool for keeping an eye on your cryptocurrency portfolio without tying up your PC or being glued to your phone: the CoinThing standalone crypto ticker.

Powered by a custom circuit board based on an Espressif ESP8266, the CoinThing is a compact configurable constantly-on ticker which pulls down data on the value of a selected cryptocurrency via Wi-Fi. "To change settings," Müller explains, "you open up a settings page with a browser. You can configure cryptocurrency, [fiat] currency, number format, chart properties, and the display brightness. There is also the possibility to update the firmware."

In the current firmware, the 1.3" color IPS display on the front of the 3D-printed housing showcases the symbol and name of the selected cryptocurrency, its countercurrency value in either fiat currency or another cryptocurrency, a 24-hour percentage change indicator, and a historical value chart configurable from 24 hours to 60 days.

The CoinThing pulls its data from cryptocurrency site CoinGecko, giving it support for around 5,000 cryptocurrencies and 60 fiat currencies. The case, meanwhile, is available in all-white, all-black, black-and-white, or white-and-copper combinations, and is secured by two screws at the rear near the USB port.

The CoinThing is now available on Müller's Tindie store at $75 fully-assembled, while the design files and source code have been published to GitHub under the permissive MIT license.
