Following my post about Different EV Connectors, it’s time to cover the process of charging an EV (Electric Vehicle) or PHEV (Plug-in Hybrid EV). Most people will want to charge their EV at home, with charging their EV at work, or when out and about being secondary to charging overnight […]

Ohm’s law (sometimes written as Ohm law or Ohms law) is one of the fundamental first principles of electronics. The law was named after the German physicist Georg Ohm and states that the electric current through a conductor between two points is directly proportional to the voltage across the two […]
I would consider handing a candidate in the UK a BS 1363 Plug, a length of flex, and an appropriate selection of tools and asking them to wire the plug, and then present the finished task. This quick interview task would allow you to see a candidate’s ability to ask […]
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 […]
