Something I’ve been wanting to do for a while: Convert a mechanical gauge to display sensor data, such as temperature or water tank levels, rather than display data on a screen. At the start of 2016 I picked up a couple of pressure gauges from an antique bazaar. Here’s the story of one gauge’s conversion.

I like to tinker and to solve problems for the fun of it. However, this project might confirm that I’m just downright lazy.
I solved two ‘problems’ this week: adding remote power-on capability to my home theater PC (HTPC) and remotely switching input selections on an HDMI switch box — by reassigning a couple of unused buttons on our TV’s remote control.

Have you ever needed to photograph a batch of objects in a consistent, repeatable way? I needed to take photos of more than 200 vinyl records to list on eBay. I couldn’t face the idea of doing this without some automation, so the Arduino-shutter-button-presser was born. Continue reading
Taking the house’s temperature — engineering edition
This is a more technical post relating to my earlier one about monitoring roof-space temperatures — where I considered whether I might be able to move my computer gear into the roof space.
Taking the house’s temperature
Could our roof space make a great computer room? That was the big question. Moving my network points, file server, router, security DVR and some other bits up into the roof would tidy up the study and reduce noise and heat in there too. But would it get too hot up there for electronics to survive?
