Title: [ANN] CGMiner Wordpress Widget
Post by: dna2 on September 27, 2013, 10:01:56 PM
Hi everybody, this is my small contribution to the community. Please be easy on me ;) Since I've installed my RPi driving four USB Erupters, I thought I needed a web interface for it. Looking at available projects, I didn't found anything I liked. So I decided to configure my own portal with Wordpress. This is the only first step in integrating CGMiner stats with it but I think is already usable (even if it's really simple). This is the result (look at the bottom left): https://i.imgur.com/zTJv3ZJ.pngThis is the configuration panel visible from Wordpress Dashboard where you can configure IP and Port of your miner: https://i.imgur.com/9dMKTWj.pngAnd this is the widget source code: <?php
/**
* Plugin Name: Miner Widget
* Description: A widget that displays CGMiner stats
* Version: 0.1
