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 […]

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 […]
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 […]

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 […]
Relays are a kind of electrically operated switch that opens and closes the circuits by receiving electrical signals from outside sources. In this post, we are going to look at mechanical relays. Relays receive an electrical signal and send the signal to other equipment by turning the switch on and […]
