Black Widow (also known as a Black Widow Ultra in Europe) is a non-commercial open source project to design a paint mix for the base of a DIY projection screen.Anonymous DIYers responsible for popularizing Black Widow in the DIY community include Mechman Alternators (US), Wbassett (US) and Custard10 (EU).

The magnetic flux threading the ring, represented by five field lines, is reduced by the same ratio as the area of the ring. The variation of the magnetic flux induces a current (red arrows) in the ring by Faraday's law of induction, which in turn creates a new magnetic field circling the wire (green arrows) by Ampere's circuital law. The new ...
This helps reduce the volume of paint used and helps in spreading an even coat of paint. A common type of voltage multiplier used in high-energy physics is the Cockcroft–Walton generator (which was designed by John Douglas Cockcroft and Ernest Thomas Sinton Walton for a particle accelerator for use in research that won them the Nobel Prize in ...
The Flux Capacitor as seen in a replica DeLorean Time Machine. The flux capacitor, which consists of a rectangular-shaped compartment with three flashing Geissler-style tubes arranged in a "Y" configuration, is described by Doc as "what makes time travel possible". The device is the core component of the time machine.
EDFMGs are especially well suited as seed power sources for explosively pumped flux compression generators and can be used for charging capacitor banks. A generator coupling an EDFMG containing an 8.75 cm 3 of magnetic material with a spiral vector inversion generator yielded a pulse of amplitude over 40 kilovolts with a rise time of 6.2 ...
Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.
At first, n capacitors (C) are charged in parallel to a voltage V C by a DC power supply through the resistors (R C). The spark gaps used as switches have the voltage V C across them, but the gaps have a breakdown voltage greater than V C , so they all behave as open circuits while the capacitors charge.
Capacitors used for suppressing undesirable frequencies are sometimes called filter capacitors. They are common in electrical and electronic equipment, and cover a number of applications, such as: Glitch removal on direct current (DC) power rails; Radio frequency interference (RFI) removal for signal or power lines entering or leaving equipment
