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!
Getting into the 4th of July? Let’s check out the pyrotechnics that ultracapacitors can generate!
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.
Bob Davis, whom some of you may remember for his high-voltage can crusher, is back at it with this 2KV, 1600A, 1500 μF 10-capacitor discharge bank that can be used to crush cans and, most amusingly IMHO, launch washers high into the air with a sound that really has to be heard to be appreciated. Bob’s video might benefit from a bit of editing; clicking the embedded player above should take you right to the money shot around 4:35. There’s also a good can-crushing right around 5:50.
From the NYCResistor crew comes this action-packed crash-course in capacitors – complete with a cliffhanger ending! Here’s hoping the saga continues with a miniature rescue mission via shrink ray (they must have one in their somewhere, right?) If after that, cap functionality still seems a bit fuzzy, check out this rather helpful little web demonstration […]
