3 LEDs powered by fingers - puzzle

Henryk GasperowiczHenryk Gasperowicz October 8, 20131 comment

The post presents a compact electronics puzzle: a demonstration video that shows three LEDs reportedly powered by fingers. The author invites readers to watch the short movie and reverse-engineer the design, asking “How does it work?” rather than providing an explanation. The write-up targets hobbyists and circuit sleuths, prompting them to observe contact points, timing, and visible wiring, then form and test hypotheses about possible mechanisms. It frames the problem as an experimental challenge — encouraging hands-on verification, sharing measurements, and discussing candidate explanations such as conduction paths, coupling effects, or hidden circuitry — without revealing the solution, to stimulate community analysis and learning.


Series circuit - 3 LEDs

The post 'Series circuit - 3 LEDs' presents only a short prompt — "How does it work??? Solution:" — without any accompanying explanation, schematic, or component values. It therefore poses a clear question about the operation of three LEDs arranged in series but supplies no data to allow analysis. The entry functions as a request for a solution or follow-up discussion, implicitly asking for missing parameters such as supply voltage, LED forward voltages, and any current-limiting resistor. The post highlights the importance of including full circuit details when seeking help and invites contributors to provide the schematic or measurements needed to deliver a correct and practical explanation.
