    The locks below are part of my collection I bought them as a job lot and didn’t know what any of them were. These are my best guesses. Gege AP1000 Cylinders I have three of these, two in brass and one that I think it nickle plated. I found what appears to be the same…

    I bought this lock as part of a job lot of snapped euro cylinders. All of them came with keys but none of them came with any information and it turns out cylinders don’t seem to have markings telling you what model they are. Two photos below show what little information I have to go…

    This is a list of all the vegetables (and maybe a few other plants) for 2024. Mostly this is for my own reference but you might be interested to see when I plant things. I live in the UK and my last frost date is between 10th and 20th March for my home site. I’m…

    Each year I try something new with my vegetable growing. A few years back it was no dig, which was a great success. This year I’m going to try long life seed trays. I guessing I’m not alone in obsessing about giving my seedlings the best start in life. It’s completely silly because they are…

    I tried the no dig method of vegetable gardening a few years ago and I was immediately sold on (most of) it. Laying a fresh lot of compost on the ground is far less work than digging it and as far as weed control goes I couldn’t ask for more. The downside of no dig…

    We’re growing much more this year than we have in previous years thanks to some extra ground becoming available to us. I was trying to keep everything in my head but it quickly became apparent that wasn’t going to work… so I made a spreadsheet. The table below is an extract from that spreadsheet. Totalling…

  • Growing Sweet Potatoes in the UK

    I’ve decided this year (2024) I’ll have a crack at growing sweet potatoes. From what I’ve read it should be possible to get a crop as long as they are started early enough and we have a reasonable summer. They are a tropical plant so they are a bit marginal in the UK. I’ve decided…

    In the previous a part of this series I gave an overview of the lamp. In this part I’ll get to the point where it’s possible to write to the LED’s. This won’t be the final form of the LED but it’ll be good for testing that it’s electrically correct. Installing Additional Software The plan…

    I’m going to start this article with photographs of the built lamp as there’s no way I’m taking it apart again for continuity. I think it’s also useful to see that it’s almost identical to what I showed at the end of the previous part. These are the interesting bits, towards the bottom left there’s…

    In part 2 I got just a handful of LED’s running directly from the Raspberry Pi. That’s a little bit risky so in this article I’ll look at some other options for powering the LED’s. Firstly… It bugged me that the pixels would keep displaying the last state when I shut the application down (killed…

    As I mentioned at the end of the last part of this series I got the lamp to the point where it was built and I’d started testing but then gave up on the project. At this point I can’t even remember how to light one of the LED’s from the Pi so it’s time…

  • Yeti – Electrical Terms

    While designing the electictrical system for Yeti I came across a whole host of thing that I didn’t understand from pull-up resitor to PNP. Guessing I probably wasn’t alone in this I thought I’d document at least some of them here. Keep in mind that I’m not an electrical engineer so this may not be…

    Now that the frame of the router table is built it’s time to start plumbing in the electrics. As with the rest of this build I’ve gone a little bit over the top and installed an industrial sized contactor. Over all I’m mostly happy with the finished product but read on for details.

    In part 2 of this series I built the circuit that I’ll be using for my controller based around an Arduino Pro Micro. In this part I’ll configure the driving simulation game Dirt 3 so that it works with the controller.

    In part 1 of this series on building a gaming steering wheel from an Arduino I installed and tested the library that I’ll be using. In this part I build and test the circuit that the controller will use. I’m quite new to electronics and I thought this would be a challenge but it turned…
