Gold is a key element for electronic devices, and since those devices are always shrinking, engineers need to find ways to make smaller components too. On that path, scientists from the University of Leeds have managed to make the thinnest gold ever created, measuring just two atoms thick. That makes it functionally two-dimensional, joining the likes of graphene.

Shiny, pretty and useful in electronics, gold has been prized by humans for millennia, but we’re not the only ones out there prospecting. Scientists from Australia’s CSIRO have now found a fungus species that mines for gold and even decorates… Continue reading Gold-mining fungi could guide human prospectors
By now we’ve all seen ways to manufacture your own PCBs. There are board shops who will do small orders for one-off projects, or you can try something like the toner transfer method if you want to get really adventurous. One thing we haven’t seen is a circuit board that’s stitched together, but that’s exactly what a group of people at a Vienna arts exhibition have done.
The circuit is stitched together on a sheet of fabric using traditional gold embroidery methods for the threads, which function as the circuit’s wires. The relays are made out of magnetic beads, and …read more
Machinists are expected to make functional items from stock material, at least hat’s the one-line job description even though it glosses over many important details. [Eclix] wanted a birthday gift for his girlfriend that wasn’t just jewelry, indeed he wanted jewelry made with his own hands. After all, nothing in his skillset prohibits him from making beautiful things. He admits there were mistakes, but in the end, he came up with a recipe for two pairs of earrings, one set with sapphires and one with diamonds.
He set the gems in sterling silver which was machined to have sockets the …read more

If you ever wondered how to make a giant-sized gold bar out of sheets of pink household insulation, well, there is a video showing you the steps. YouTube workshop guru [Jimmy DiResta] built oversized prop gold bricks out of foam. He cut sheets of 1.5″ Owens Corning foam insulation on his Saw Stop, making angled edges onto each piece so they could fit together in the trapezoidal ingot shape we know and love.
The pieces were put together with Great Stuff insulating foam sealant, the sort of spray foam used for filling up gaps in your house’s insulation, but here …read more
