London-based designers Martin Riddiford and Jim Reeves — from Therefore.com – spent four years developing a light that would provide a viable alternative to kerosene and sun-powered lamps for developing nations. GravityLight works by harnessing…
This is a spinning magnet top that is being powered by indoor indirect sunlight. The circuit is a simple two transistor / one coil design. A regular 22uf electrolytic capacitor is used instead of…
This shows an idea for a light powered motion desk gadget that can hold notes. The driver unit is out of a light powered waving flower and will work at light levels found in…
This is a short range radio transmitter that broadcasts to an empty station on the FM band. The circuit is a modified ‘Cool Joule’ by TinMan. It is very simple but the parts values…
This is a simple one transistor short range FM transmitter. It runs on 3 volts and the circuit is based on one that saw here on Youtube. The circuit was put together with parts…
Potential Difference Inc. Infinite Range ebike Project. This project is designed to produce an EV prototype which drives a ReGenX generator whereby the generators’s Regenerative Acceleration output power matches or exceeds the input power…
Further developments toward the goal of a self running system, similar to Dr. Stiffler’s PSEC unit. Today, i’ve had the goal of tuning to a Walgreen tower with ‘traditional’ Slayer exciter, running on just…
This is a JLN Labs replication of a Potential Difference Inc. DC powered Bi-Toroid Transformer (BiTT). The BiTT does not require an increase in input current like conventional transformers but rather uses the Secondary…
The Fountain of Heron, aka PerPump For how long must a self-powered water pump run to qualify for MrWayne’s ten large? Oops… I forgot to put in a Zed. Oh well… back to the…
