Diode or P-channel MOSFET is what you need to protect your circuit from applying reversed voltage, according to a nice video published on Afrotechmods channel. Method 1:Diode The simplest way is to use a diode in series with main power supply. When you connect the power source...

Moore’s law states that the number of transistors doubles every two years. Rachel Courtland from IEEE Spectrum explained the sharp turn of Moore's law in 2021. Chip manufactures will switch to another way of boosting the density in the chip by having multilayer chips using vertical...

This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulators. LM3X7 series of adjustable 3 terminal regulators is capable of supplying in excess of 1.5A...

A.Qadry @ Intelligent Minds tipped us with their latest project, a PCB prototyping machine. They are going to crowdfund the project soon so if you are find it cool you can follow them on their facebook page. There are mainly two ways in talking about manufacturing, if you are going...

Recycle Plastic Materials like a few meter leftover 3D Printer material or even Plastic Bottles into Pellets to create new Objects. Do you own a 3D printer like most Maker and DIY'ler?  almost run out of filament? ... Again? What to do with the last few meters? well... Make...

Outfitted with a 2-A, 28-V power switch, the LT8335 2-MHz step-up DC/DC converter from Linear Technology operates from an input of 3 V to 25 V, suitable for applications with input sources ranging from a single-cell lithium-ion battery to automotive inputs. The LT®8335 is a current...

A team of scientists at the Kavli Institute of Nanoscience at Delft University has achieved what may represent a limit in information storage density by creating a memory in which a single bit is represented by a single atom. By Graham Prophet @ edn-europe.com: Specifically, the team...
