How to Make a Capacitor From Scrap Aluminum
Jezan needed a variable capacitor for a project. Not having one, he created one out of scrap aluminum.

Ultracapacitor Experiments
Jesse Holleran’s quirky video demonstrates a bunch of experiments he did with a 3,000-farad capacitor, including welding two pieces of metal together melting a paper clip, and electrolyzing water into oxygen and hydrogen.
MAKE Presents: The Capacitor
Collin Cunningham provides an elegant description of capacitors, including early caps called Leyden jars.
Super-Capacitor Flashlight
Patrick AKA EngineeringShock built a flashlight that uses no batteries, and instead charges up a bunch of caps from a wall wart.
SMD Capacitance Hack
Akiba of Freaklabs, a Tokyo-based open-source electronics kitmaker, needed to add some 0805 surface-mount capacitors to an existing PCB, so he stacked them up! super ghetto bulk capacitance hack. my RF amp is more power hungry than i expected… See the related links below for more of Akiba’s awesome work!
Dangerous Fun with Super Capacitor Pyrotechnics
Getting into the 4th of July? Let’s check out the pyrotechnics that ultracapacitors can generate!
Component of the Month: The Capacitor
I’m super excited for this month’s component: the capacitor! It’s an electronic component that stores a small amount of energy in an electrical field. Caps make up a very diverse family of components! As usual, we start off our coverage with an excerpt from Charles Platt’s stellar Encyclopedia of Electronic Components, Vol. 1.
