To check the operability and polarity of the LEDs, the master developed and manufactured a tester. The tester works on CR2032 batteries, and the master uses a copper self-adhesive tape as a conductor.
For the manufacture of tweezers-tester, the master used the following materials:
-3 mm - 3.5 mm MDF;
-Three screws m3 12mm;
-Three nuts M3;
Self-adhesive copper tape;
-Scotch;
- Battery CR2032;
The master cut the basis of the tweezers from MDF on a laser cutter.

Well, it remains to collect the tester. Cuts and glues a copper tape to the inside of the tweezers. It is necessary to glue it so that the tape contacts the battery plus on one side, with a minus on the other and does not close with screws.
Everything is assembled, it remains to check the tweezers tester in work.
