To test if transistored circuits with 2N3904 transistor can operate on 2.5V power supply I build a simple astable multivibrator. The components are of the shelf. I found some schematic. As on all my experiments, the value of condensators is readed from them, but value of resistors is measured.
I note some formulas describing the multivibrator.
The las thing I did is connecting som old analog meter to multivibrator and made some video of it.

On the schematic there are BC547, on the breadboard I hac 2N3904.
I havent time to buld an NAND gate, but what I did is chenge capacitors from 10µF to 5µF and build a second one multivibrator nexto to first. Its the same schematic, only capacitors have value 20µF.
