A Breadboard In A Browser

[Flownez] sent in a tip that a port of the venerable Falstad circuit simulator is now available that doesn’t require Java (it uses HTML 5). This is a welcome port since some modern browsers (particularly Chrome) make it difficult to run Java applets and prevented the Falstad simulator’s execution.

Like the original simulator, this one is great to show a classroom circuits and encourage building or studying circuits in the browser. There’s no extra software to install, which is handy for an impromptu demo. Another cool feature is the visualization of current flow as animated dots. The dots move in …read more

Automatically Designing 3D Printers From E-Waste

No one wants to design consumer electronics that last longer than a few years. This trend is an ecological disaster, with millions of tons of computers, printers, fax machines and cell phones ending up in landfills. In these landfills, all the lead and chemicals used to extract minuscule amounts of gold plating leech into the environment. Turning it all around is monumental, but reusing some of this waste can help make a difference.

[Masterperson] and [Maaphoo] have been working on a way to turn those tons of e-waste into something useful. They’ve come up with a framework for turning e-waste …read more

Hackaday Prize Entry: A Better Bench Power Supply

Back in February, [The Big One] started building the bench power supply to rule them all. His previous power supply was just an ATX computer power supply. It worked, but that didn’t give him fancy stuff like different channels of individually adjustable voltages. Since then, we’ve spun up the 2015 Hackaday Prize, and [The Big One] has changed his DIY power supply into a Hackaday Prize entry that competes well against $1000 mid-range commercial units.

The single most expensive component in this power supply are a pair of isolated switched power supplies rated for 15V and 7A. This is a …read more
