I had to mix more DIY
e-liquid. I make 200ml at a time. I dated the last batch to see how long it lasted... from 9-2 to today. That's only about 4.83ml per day. I thought I was using a lot more than that. I was happy to see it.
I'm in the process of building a Battery Tester which I was given the Schematic for by a guy in Ask the Vets. It uses a 3.0Ω Resistor and a Switch. You read the Battery Voltage Output straight off the Battery, and then switch in the Load and read it again. Then you do a Mathematical Formula that tells you the Physical State of the Battery... from "Like New" to "Needs to be Replaced." I stopped for a while to come here.
Other than this, it's been pretty slow.
