Kindle beer meter

I’ve a liking for anolog dials,  so I set about looking for something that could display various metrics of fermentation.   I had an old kindle laying  in a drawer unused and wondered if it was possible to. 

There are a few kindle mods to disply weather data on kindles. Basically it involves rooting the kindle (I don’t recommend this on your kindle that you may use daily unless s you’re willing tonrisk bricking it)  

After rooting,  various utilities are installed,  mainly the usb hack.  This will enable ssh into your kindle. Here I wrote a sxript to grab the last value off thingspeak.com where my fermentation co2 interval is logged.  This is then converted to analogue and displayed on the kindle.  Beer meter! 🙂
