Measuring Capacitor Health (tan δ vs ESR)

One of the leading causes of early device death for electronics is the failure of one or more capacitors in the power supply. This is doubly true for devices that see high currents, run hot or have their boards in enclosed spaces. Devices such as LCD/Plasma TV's, computer power supplies and even old...By: PedroDaGr8Continue Reading »

The Entire Commodore 64 Library In Your Pocket

[sweetlilmre] is just beginning his adventures in retrocomputing, and after realizing there were places besides eBay to buy old computers, quickly snagged a few of the Amigas he lusted after in his youth. One of the machines that didn™t make it into his collection until recently was a Commodore 64 with Datasette and 1541 drive. With no tapes and a 1541 disk drive that required significant restoration, he looked at other devices to load programs onto his C64.

These devices, clever cartridge implementations of SD cards and Flash memory, cost more than anyone should spend on a C64. Realizing there™s ¦ Read the rest

You Might Be Cool, But You™re Not Gas Turbine Motorcycle Cool

For the last four and a half years, [Anders] has been working on a motorcycle project. This isn™t just any old Harley covering a garage floor with oil “ this is a gas turbine powered bike built to break the land speed record at Bonneville.

The engine inside [Anders]˜s bike is a gas turbine “ not a jet engine. There™s really not much difference in the design of these engines, except for the fact that a turbine dumps all the energy into a drive shaft, while a true jet dumps all the energy into the front bumper of the car ¦ Read the rest

Astronaut Or Astronot: Nobody Won (This Week)

Another week, another round of Astronaut or Astronot, the little lottery thing where we try to give away some fairly expensive tools to a random person on if they have voted for The Hackaday Prize. You should vote. Go here and do that.

This week, the random hacker selected was [oscar6ojeda], but he did not vote. This means he doesn™t get a huge bench power supply. Oh well. I™ll send him a t-shirt and a few stickers. That™s fair compensation for doing nothing, right?

We™re doing the same thing next week, so go here and vote. ¦ Read the rest

Bil Herd: Computing with Analog

When I was young the first œcomputer I ever owned was an analog computer built from a kit. It had a sloped plastic case which had three knobs with large numerical scales around them and a small center-null meter. To operate it I would dial in two numbers as indicated by the scales and then adjust the œanswer by rotating the third dial until the little meter centered. Underneath there was a small handful of components wired on a terminal strip including two or three transistors.

Science Fair Analog Computer

In thinking back about that relic from the early 1970™s ¦ Read the rest
