Here is a simple 12 V inverter for using a small soldering iron (25W, 35W, etc) in the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors T1 and T2 ...

Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 ...

University of Illinois researchers have developed a way to heal gaps in wires too small for even the world's tiniest soldering iron. Led by electrical and computer engineering professor Joseph Lyding ...

You’re going to want to do some stretching before undertaking a soldering project like this one. We’re betting that the physical toll of assembling this 4-bit discrete processor project is starting to ...

Transistors have come a long way. Like everything else electronic, they’ve become both better and cheaper. According to a recent IEEE article, a transistor cost about $8 in today’s money back in the ...

Researchers have developed a way to heal gaps in wires too small for even the world's tiniest soldering iron. Junctions between nanotubes have high resistance, slowing down the current and creating ...
