Like the bearing size code, resister values for LEDs is something that I keep needing to work out, or just go back to my nominal somewhere between 200 Ω and 1 kΩ rule of thumb. While I could work it out every time I need it using and then chose […]

I have spoken to Pycom support about the problems I was having updating the expansion board, and it turns out its a known issue with Mac OS 10.15 due to the security settings in the new version of Mac OS. However the expansion board should have come from the retailer […]
One of the things I use my iPad mini and Apple Pencil is taking notes on components from the data sheets. I also have a iPad keyboard case that allows me to use my iPad as a very small laptop, or have the screen propped up for use as a […]
I downloaded Notability to give it a try, back to back with Goodnotes, both are about the same price from the App and iPhone/iPad stores, I bought both the Desktop and the iPad app to test on my iPad mini, with my apple pencil, and the desktop app to test […]
This work from home thing means that I am working in the home office. Time to finish typing it up. And getting all the small things put into the right boxes etc.
I have got my PCB rule business card PCBs back from JLCPCB, so now to check everything works and build one up
On Facebook a friend of mine put out the following request: Calling all 3D printer friends. Can you print up some visors for the doctors and nurses. There’s a plan somewhere of how to do it using a 2l bottle as the visor and the 3D printer bit as the […]
On LinkedIn a while ago Glen one of the reps at Würth Elektronik offered free PCB fidget spinners. I asked nicely if MiniBoyGeek could have one, and as such one was delivered, I am glad I opened the bag before giving it to him. A fun little build of 9 […]
At work, I am trying to make some automated test equipment, (I also have some personal test equipment to automate as well). At work I use MS Windows 10 for my laptop, home I use macOS, and for embedded test equipment I am planning on using Raspberry Pi and Pi […]
I have a selection of common-ish values of components I use in my designs. I bought a Starter kit of 0805 size Surface Mount Resistors from Electronic Things a while ago, this gave me most of the values that I have made spaces for in my boxes. I also have […]
After my last attempt at getting MyOpenLab to work on macOS, I posted my question on the MyOpenLab Facebook group, where I was given the following response: Hello, what version of MyOpenLab, Java and OSX are you testing? You could test the most recent development version: https://myopenlab.org/…/distribution_macosx_3.12.1.zip The fail could […]
I have been trying to design a K9 for 3D printing for a while, even using Fusion 360 getting the body design has been a stumbling block, On Facebook, there is a k-9 builders community and a link to a OneDrive account with 200 x 200 sliced STLs. I have […]
I can’t remember where I came across this paper on the design of a ball lock multi-speed transmission system, written by students at the West Virginia University Institute of Technology The SAE Mini Baja team requires a custom, multispeed transmission for their vehicle. Concurrent engineering with the Baja design team […]
Tamarisk has been making use of Bob’s AnyCube printer to make Christmas card presses for use in her Adana letterpress machines, (At some point they should write blog posts about it!) The presses that they can make in Bob’s printer work fine on the 5 x 3-inch press, but the […]
I know there are probably about a million of these tutorials all over the internet; however, this is my setup, so I know what I did should I need to do it again… Prerequisites VS Code needs to be installed on your system. The standard Arduino IDE needs to be […]
A beautiful print using my roll of Filamentive grey filament, this is the battery and electronics sledge for my 3d Printed ROV. I am doing my design in fusion360, and printing the parts on our Prusa MK3s. Thanks to Ravi Toor of Filamentive for getting me the filament to play […]
I have been working on my DIY underwater ROV (remotely operated vehicle) for a fair while. It is going to be an underwater robot, sometimes people call them remote controlled submarines. I have moved some of the development to my Professional site: In the interim, I am going to have […]
With what I learnt from making PCBs last time, I was speaking to ‘The Langster!‘ at work, when I had some thoughts about improving the SMT Stencil / shield we use to apply the solder paste, I have had another quick look at the Manchester Hack-space’s IR oven, a little […]
