Not long ago we speak on as doing a home-made electroscope.
Now we go a little further on and leave a scheme that we have found for the construction of an electronic electroscope.
The scheme of the assembly is the following one.
The necessary materials are:
- Battery of 4,5 V
- 2 terminals "faston"
- thread of flexible copper
- Universal moles badge
- 2 resisters 1kOhm
- 2 resisters 100 kOhm
- 1 diode 1N4007
- 2 transistors BC557
- 1 transistor BF245C
- 1 red LED
- 1 green LED
- I tin to weld
- Welder
You already can only do only tests rubbing diverse materials.
