picotherm: Controlling an OpenTherm Boiler with a Raspberry Pi Pico

Introduction In our old flat, we had control over our heating from our phones: I’d reverse engineered the RF control protocol used by our Salus thermostat. I never got round to blogging about that, but the code is available here. Now we’ve moved, we wanted the same control. The new boiler is a “Baxi 600”Continue reading “picotherm: Controlling an OpenTherm Boiler with a Raspberry Pi Pico”

Power Monitoring with a Raspberry Pi Pico

We had a smart meter installed last year. It’s kinda useful to observe long term power usage. However I really wanted to be able to see more detail; like turn off this device, what happens to the power usage? I didn’t find the wee standalone meter module thing that came with it very useful. Luckily,Continue reading “Power Monitoring with a Raspberry Pi Pico”

Afternoon Experiment with Veneer

A friend, Sandy, suggested trying laser cutting wood veneer (he has plans for a complex design).  However, I’d not tried that before, and it sounded like an interesting idea. I’ve often watched people on Youtube restoring veneer, for example, the excellent AT Restoration. I ordered some cheap samples of veneer from Amazon, and, when theyContinue reading “Afternoon Experiment with Veneer”

Lasercutting Lathe Toolbox

One problem with the lathe is I now have a whole set of chisels lying around the place, which is kinda annoying. I spent yesterday designing a quick tool support to attach to the lathe bench in Fusion 360 as usual: I cut it on the laser cutter out of 5mm MDF: Unfortunately I madeContinue reading “Lasercutting Lathe Toolbox”

Wood Turning Lathe!

I’ve always wanted one of these. When I was wee, we went on tour round England visiting various relations, and I remember being very impressed with a lathe. I’ve no idea which relation it was, unfortunately, but I do remember the lathe. I decided to order one from the UK rather than direct from China,Continue reading “Wood Turning Lathe!”

Making a Hammer

Nicola bought me a present for my birthday: a hammer making course at Athelstaneforge! I really enjoyed it! It was a pretty intense few hours though: hitting chunks of hot metal with a sledge hammer to shape the head, followed by grinding and polishing it, and finally adding the handle. Would very much recommend it!Continue reading “Making a Hammer”

Boring 3d Printing: Ceiling Cable Covers

Time for some slightly boring, but useful, 3d printing. The Problem When I wired the house, I was planning on adding ceiling mounted wifi access points. However, in the end, I didn’t use them. So we were left with a few cables hanging out of the ceiling. After a while, we stopped noticing them 😀Continue reading “Boring 3d Printing: Ceiling Cable Covers”
