Ground loops are a mystery to many people. Even seasoned electronic engineers can struggle to understand the concept of ground loops. This is generally because either the engineer is focused on designing the power distribution system or the equipmen...
When soldering surface-mount parts, half the battle is obtaining a reliable grip on the components when manipulating them into position. Another battle is seeing them !
I lost a really nice pair of VOMM PSF-SA-ESD tweezers, so I was keen to repl...
I had some time to experiment with my new MP730026 multimeter and was intrigued to know if I could get the BLE capability functioning. I wanted to be able to access the meter from the laptop, and the mobile phone! The MP730026 was interest...

Due to the current shortages of parts, and the escalating costs, I decided to skimp a little and buy a bunch of thermocouples from AliExpress, because I needed quite a few for testing a couple of projects.
Unfortunately, they will all need to be car...
