Here’s a little tip for you; if you’re experimenting with an Arduino and a CurrentCost, trying to see if you can power one from the other and you have the 3.3v pin on the Arduino connected to the unregulated power line on the CurrentCost’s interface port, don’t then have a brain fade and plug the…
As part of a “grand plan”, I’m thinking about how to implement a feature rich Arduino web application, without getting myself tied up in knots worrying about blowing the capabilities of the ATmega in terms of program size, memory size or processor speed. Without an SD card to store all the files on, the simple…
Hmm, my plan for powering an Arduino from the CurrentCost energy monitor has hit a little snag – the idea was to use the 3.8v unregulated supply on pin 1 from the CurrentCost. I could then run either a Xino at 3.3v or boost it up to 5v. However, as soon as I put any load on that…
Despite some of the shonkiest soldering in living memory, the Xino Basic that arrived the other week is now built up and – rather amazingly – fired up first time. Well, to be fair, the soldering itself wasn’t really the problem; it was more a combination of me simply not putting components in straight/flush before…
Last week I got a hold of a new kit from Ciseco for an Arduino ethernet shield based on the ENC28J60 chip and spent some time today soldering it up. Now, to be brutally honest, the only soldering I’ve done for a long time before now involved a gas-powered iron and a Ford Capri, so…
Postman’s just delivered a little box of treats from Ciseco. Having taken them out of their wrappers, I’m a little nervous about ruining their nice clean appearance through my ham-fisted attempts at soldering, but the upside is that these kits are at the bargain basement end of the price spectrum, so if I really trash…
Rapid Online supply a range of pipe-clip temp sensors, for a couple of pounds each, that will be useful for monitoring temperatures within the heating system. Granted, they’re never going to give me actual water temperatures as they’re measuring the pipe rather than the water itself, however, over time they (should) give consistent data, which is just…
