Here I am, adding another meter to my car. This time, its a voltage meter plus some extras switches. Yeah, my car's electrical is going nuts, which I suspect could be due to the rusts. The voltage meter is for me to see how the car is doing but for all you know, it won't drop or rise as I expect. Maybe I should have gotten an ammeter with a 100A shunt instead. As for the switches, the red one is to monitor the brake lights while the white one is for reverse lights. Should any of the two not working, I will simply press the switch to bypass them manually.
To tell you the truth, I wanted to do the brake light switch ever since I got the car in the late 90's to simulate an emergency brake. But the switch would be those industrial mushroom types and p;aced in front of the dash in such a way that the driver behind cannot see I pressed it. He he he he.
Introducing one of my 'latest' tool, the metal nibbler.
Its the latest because I kept it for years and just got
to see it again. I asked around on how to cut metal
and Multifilla showed me a tool which is exactly
like mine. I am so stupid.
you can start 'nibbling' the metal until you get the
shape that you need.
but there is not enough space. Too bad.
just bolt on a 5v voltage regulator to the
metal casing which then acts as a big heatsink
Unfortunately, I can't find my heatsink thermal
am not taking any chances and so, I will use those
heatshrink tubing for the voltage regulators. And
when I need to wire up the switches later, it'll be
very messy in there.
which has dimming problems. Since I do not have the
original specs, I used the next best component. So, it
now has a very bright display but cannot dim much.
right have spoilt displays and well, I am not going to
try repair them since I just opened them a few mins
ago and I suspect it has something to do with the
microprocessor IC. And I do not have the HEX files
to program them.
