Wow, damn it! I like, but how did I cut out the panel for a voltmeter?
I also liked it)
A hole in the thick (>4 mm) I also didn’t know how to cut plastic, until I came across a turbo lighter)
Need for cutting
1) stationery knife (and it is desirable to have spare blades on hand)
2) a heater (a simple lighter or gas stove is suitable)
First you need to draw a hole of the desired size on the plastic. Then you need to draw a hole 3-4 mm smaller in it (i.e., you should get a rectangle with sides 6-8 mm smaller than required). Then we heat the blade of the knife and try to draw it along the small contour (we don’t touch the large contour, it is adjusted with a file). If the plastic cuts through, but it is bad (not through and through), you need to increase the temperature, if the hole pierces instantly and its edges diverge by a couple of mm, then we reduce the heating - I had it from the very beginning, it’s good that I cut it in the middle of the future hole.
Ideally, there should be a feeling that you are cutting cheese with a rounded knife (there are definitely such ones in the dining rooms)))).
So, the hole is cut out, and now the hole is adjusted with a file, and very carefully, with a constant check of dimensions. Actually, everything else is a matter of technology, there is soldering the wires to the voltmeter and LEDs.
Yes, we must not forget that LEDs have different nominal parameters. The script for calculating the resistance to LEDs is on casemods.ru, on the main page on the left, under the site menu.
Oh yes, I forgot to say - in life everything looks MUCH more beautiful than in the photo)
