I have been building some of the components for my digital dash .. the other day I decided to test out the bar graphs.. this is the video of that ... now i am cleaning them and coating them with a product called liquid tape (for electrical tape). Once they are all dry ... buy time I am done typing this I need to get some nerve up and superglue them all together in one unit. Then in the near future I am looking at getting a different radio. This one will be a inch smaller top to bottom ... this will leave a gap to be filled above the radio ... These should fill it nicely. The second video is my Zener Diode battery equalizers at work. It shows how They shunt power from the full batteries and don't take it from the week ones. I am graphing the batteries daily but a few days into the graphing I found a Bad cell In battery 14.. So it kinda was throwing a wrench into the works ... But graphs will be coming some day

Digital Dash.

Digital dash project.
I am eliminating the Paktraker because it has never really worked properly. It never read the Amp draw correctly. So I ordered 2 panel meters for the dash. I have made a 9v. power supply and a voltage divider using these guides. 9 volt power supply and the voltage divider.

I got the dash out with no problem. Used my handy dandy Dremil tool to chop the dash and then started mounting the panel meters and power supply. Then there was a problem ... the top panel meter was reading gibberish ... So i connected up my leads to the bottom one and it read correctly ... Either it is faulty or I damaged it playing with it the other day ... I will order anther and hope it gets here before long. This bottom picture is the top gauge on the fritz and the bottom hooked up to a 9v battery.

It's been a cold winter.

Back into the EV driving season ... hopefully It will become 70 soon and just stay there. I have been starting on some projects. Mainly I have been buying stuff for projects. I want to build Zener diode Battery regulators. Right now I have no pack balancing so I want to make a set and then as a Help to the community I want to monitor the improvements. I am also making a 10 led Battery bar graphs for each battery. My Paktraker has crashed and I am not interested in replacing it.
