There’s something wrong with my Stash

Since the weekend I’ve been trying to work out why the code to upload data to my Cosm feed was falling over after random periods of time. Sometimes it lasted for a few hours before dying, but others it lasted just minutes. There was no readily visible pattern, so it was time to get Googling…

Finally uploading some CurrentCost data

Having established how to power my CurrentCost monitor, the next step was to start using an Arduino to upload the data to one of the many Internet of Things (or IoT) data bucket sites out there and – for a first step – Cosm (what used to be called Pachube) seemed like as good a starting point…

First steps with a GPS module

A while back I saw a new product on Adafruit’s blog and instantly thought “I gotta get me one of those!” Its official title was “Adafruit Ultimate GPS Breakout – 66 channel w/10 Hz updates – MTK3339 chipset” and the feature list just kept on scrolling down the page. Now, I’ll be the first to…

Turning the power problem on its head

Regular readers will remember I’d previously had a problem trying to run an Arduino from the power line of a CurrentCost CC128 energy monitor using the CurrentCost’s own PSU for both devices, wherein as soon as you connected the additional load of an Arduino, the CurrentCost stopped getting readings from its remote sensor. The reason…
