How to Use a Power Supply 

The ground wire does not need to be connected to ground but you can connect the ground wire to a piece of metal touching the ground

Hi there, a bit late to this but generally they're called "helping hands" I believe. They're common for soldering components. Hope this helps. :)

Thanks. Actually, timing is perfect 👍

Does anybody have any recommendations for my first power supply I was hoping to get something with oscilloscope I am not rich so I can't buy the £1000 I'm looking at around £150 But I could make a power supply out of an old pc power supply And just buy a scope

Yes, this type of bench top power supply will work well for testing lights and motors, as you can set the voltage and limit the current.

Coarse moves the amperage level up faster (like 1 2 3 4) and the fine knob moves it in smaller increments (1 1.1 1.2 1.3 etc) This is so if you’re hooked up to a motor let’s say, and you want to hit a specific RPM, you could get it close to speed using coarse and than fine tune the power with the fine knob.

I'm not an expert by any means, but some things to ponder. Keep yourself dry, anything under 24v I personally consider safe in completely dry conditions. Osha says up to 50v should be relatively safe in dry conditions not to say you can get shocked or burned still. You even feel even 9v your tongue. In general mitigate physical contact if you can, ppe like good rubber shoes and gloves might not be a bad idea if your not sure. Again not an expert but I've worked a lot on 12 and 24v systems DC. Currently I'm working with 48v batteries and those I'm going to be using ppe

Thanks!

no. take a look at what people that make money do to make it

Because most power supply function the same way??
