Centurion wireless electricity – goal met, Zero mA
An update on the project to use as little current as possible within a wireless electricity circuit.
Into the realms of meter error, the needle now doesn’t move on my Sperry analog meter.
The whole aim here has been to use as little energy as possible…not necessarily to increase wireless induction ranges or other such goals.
For the arguers and down thumbers out there, 0.4mA would still be 0mA rather than 1mA…people get very wound up and jittery when the word zero is used and of course it is using ‘some’ current !
Base resistance from the Positive rail does play an important part when wishing to run several LED’s, small devices like digital watches or a small motor, but for the least current, that transistor Base resistor has now been removed.
Trial and error bench testing has resulted in the circuit now shown.
The transmitter coil is of 23AWG, wound on a pills bottle and then secured with electrical tape. 24 turns, pull a piece out to the side (which connects to the Positive battery supply) then wind another 24 turns. The receiver coil is of 24 turns of the same wire, with an LED sitting directly across the ends.
The receiver coil will work better one way up than the other. The transmitter coil will work better with the wire ends connected one way than the other.
The circuit also relates to my recent SWES 2 video.
Just add a 1 Meg ohm resistor and ceramic capacitor in series to the Base for similar efficiencies.
