tl;dr; I have not yet managed it… but if you read on you will see where I am currently up to, and where I think I can go. I am reading the University of Toronto’s “Self-Driving Cars Specialisation“, one of the tutors is Paul Newman from Oxbotica: Be at the […]
On Saturday Tamarisk, MiniBoyGeek, Thinkl33t and I went to The MAD Museum in Stoke-on-Trent with Emily and Glen. We also found a nice little vegan coffee shop called Plantarium. Emily made Tamarisk and I a Flappity Bat for Christmas: Go look at her shop!
I have bought a Pycom makr WiPy to have a play with Micro Python, the recommended IDE is atom with Pymakr Atom Package, however it doesn’t work out the box as designed due to an issue with Atom and Pymakr. After you have installed Atom from atom.io, you can open […]
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 […]
Since I got Pycom working on my Mac, I can now update the firmware on my expansion board, the DFU updater is available in Brew, which we should have installed in the last post. From the Updating Firmware page we can download the correct firmware file; I have the Expansion […]
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 […]
It has been a while since I have tried getting CARLA to run. After doing fair amount of poking, and prodding including trying to compile Unreal Engine for use on the NVIDIA Jetson Nano; I was unable to get Unreal Engine running on the ARM® A57 architecture. Since then I […]
Every so often I update my CV, I am not a huge fan of Microsoft Word, or other Word Processors. Texmaker is a free open source LaTeX editor that works cross platform, on my Mac it makes generating my CV simpler. My CV is now stored in my GitHub account […]
I have got my PCB rule business card PCBs back from JLCPCB, so now to check everything works and build one up
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.
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 […]
A while ago I managed to get Libvert running on OS X. Sometime last year, things were changed in the Brew.io version of LibVert that caused you to no longer be able to open the information screen on VMs that you are running. The problem seems to be that the […]
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 […]
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 […]
Over the last year, Glastonbury Town Council has been doing a “fact-finding” mission on the impact of 5G on human health so they can work out if they should promote the roll-out of it in Glastonbury. I suspect this is at least partially in response to the Glastonbury Festival trials […]
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 […]
Following on from my recent post about Glastonbury’s fun and exciting 5G report, I have had the chance to review the full report in more detail, the one that was pulled from the website and replaced with the executive summary… The executive summary is a dull document, that has redacted […]
After having a go at assembling the ears printed in the [[blog:k9_nose_gun|last post]], I decided to have a go at making something a little easier to assemble. [[wiki:projects:k9:reference:mat_prentis|Mat Prentis]] assembled this guide that gave me the dimensions below: Heading into Fusion360 I generated the following model: [[tag:thinkl33t]] Sliced it and […]
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 […]
To avoid this joke in future, I have started printing my K9’s head by printing the two parts of the nose first:
I came across this video via the K9 Facebook group, it was published a while ago, when I get a chance I will sit down and listen to it.
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 […]
There is a more in-depth and up-to-date version of this post over on PhilipMcGaw.com, in addition to the post about KLR, KL15, KL50, KL30, and KL31 codes, there is an entire post about Automotive Relays and their nomenclature. If you spend any time more involved with vehicles than reading a […]
Since my last Workbench Friday Photo we have moved house, and built a much better home office! Complete with a better view, and more storage for random stuff! My Wife, Tamarisk is in the middle of making Christmas Cards, so that is why the Adana printing presses are out on […]
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 […]
