Around the world, there are a variety of different EV charging connector types used on Battery electronic vehicles (BEV) and Plug-in Hybrid Electric Vehicles (PHEV). The use of EV Connectors tends to be split into geographical regions, with different connectors being concentrated in each geographical region. EV charging connector types […]

For some reason a list of links to other peoples blogs is called a blogroll (I am not sure if links to sites made in software that is not blogging software is also a blogroll, but YMMV)… so here is my PiWars blogroll. Since I got accepted as a backup […]
Nathaniel Poate of Team Shortcircuit Robot Bits supplied me with five drill motors, these are drill motors from cordless battery-powered drills. Three of them are 12 V, and the remaining two are 18 V motor and gearbox sets, these were given to me for use with robotics projects. I received […]
After the Origin issue, another one of KiCad’s slight annoyances is when the contents of the paper space title blocks get out of sync, looking at the support tickets, this is by design, however, it doesn’t stop it from being an annoying “feature”. This is especially problematic when you go […]
When you have been using KiCad for a while to make PCBs, one of the things you will come to find is a pain is that by default the KiCad grid origin is set up in the top left of the Paper Space, which makes it a bit of a […]
I have put my registration in for PiWars 2024 – Disaster Zone. PiWars is “The Raspberry Pi Robotics Competition”. PiWars is a Non-Destructive robotics competition run by members of the Cambridge Raspberry Jam. It will be held on Saturday 20th and Sunday 21st April 2024, in Cambridge UK. Full details […]
In my previous two posts, Pressure Vessel and the Viewport, I talked about using the software “Under Pressure” by Deepsea to work out the performance of the Pressure Vessel tube, and the Viewport for my ROV. it’s now time to work out the performance of the end cap which holds […]
Further to my last post, where I was using “Under Pressure” by Deepsea to work out the performance of materials for the main pressure vessel of my ROV. I am going to look at the performance of the Viewport Dome. Since the viewport needs to be optically clear this discounts […]
Since the electronics on my Remote Control ROV will be underwater, they need to be isolated from the water, and the subsequent water pressure, for this I am going to use a pressure vessel. There is a commercial product the “SEAWOLF Ocean Master” that looks like it has a transparent […]
I can’t quite remember how long I have been interested in seeing what is under the water, I have been writing my thoughts about building an ROV on my old site for a while. I picked up a copy of the book, “The ROV Manual – A user guide for […]
My preferred ECAD software is KiCad. It is now at version seven, and over recent years has been developed to be more and more powerful. I used to use CadSoft Eagle CAD until it was taken over by Autodesk and became part of Fusion 360. I use KiCad for both […]
Contactors are more than just a large relay, their internal construction is designed to be capable of carrying far higher currents and “making and breaking” on large loads. Rather than moving the common contact back and forth on a pivoting armature, contactors move a large bar towards or away from […]
