I2C Mini Shield
The proto shield I’d wired up for the LCD experiments was getting a bit full and I needed to wire up my rotary sensor board so rather than try and add yet another item to it I thought I’d make

Response Welding Gas Monitoring
At the end of last month I posted an idea about monitoring welding gas levels. Jeff Baker from Home Built Workshop responded on twitter to say that he’d had some successful experiments feeling for a temperature difference to find the
Magnetic Sensor Test Rig
Rather than try and combine the electronics and metal work into one setup I thought I’d build a test rig for the magnetic sensor board that I soldered up the other week. This will allow me to prove the circuitry

Tiny chip Soldering
As part of my investigation into alternative solutions for my digital rotary table I thought I’d have a look at the AS5048B a clever little chip with 4 hall effect magnetic sensors and some digital signal processing. This allows it
Welding Gas Monitoring
I noticed at the weekend when I was welding that the pressure on my 10L argon canister was less than I remembered it being. I wondered if it might be time to visit Weld Air Supplies in Dunstable to get
