I teardown and then test a car USB adaptor which seemed to be giving trouble when in use, however the testing showed it was still working OK.

I unbox (eh up Chris) and do some basic testing of a Solartron 7075 7.5 digit multimeter which I just purchased (and may need repair), if it does need repairs I will be doing some vidoes about it, so make sure you subscribe if this is something you might want to see!

I was setting up an LM317 adjustable voltage regulator circuit to replace an old 1.35V Mercury D cell that was inside a Fluke 540B Thermal Transfer Standard.
I noticed that the output voltage was only stable when the input was below 7V, above that and its output increased with increasing input voltage.
I thought I would do a little video showing what I found, it may be helpful to someone that is trying to use the LM317 to build a power supply.
