What Are Supercapacitors?

Supercapacitors have been mentioned from time to time due to their uses in some hybrid and electric vehicles, as well as other devices, but what are they? A supercapacitor is an electric double-layer capacitor. It differs from a conventional capacitor in that it offers a significantly higher energy density. As is the case with conventional…

TI Introduces Crystal-less MCU Using BAW

The crystal oscillator is a longstanding concept that employs a physical oscillator for clocking to facilitate accurate timing in electronics. These oscillators have been driving CPU clocks, as well as low frequency (and low power) non-CPU clocks in devices that need to be able to use their peripherals (for example: analog to digital converters) while…

Comparing The Raspberry Pi 3A+ Vs The 3B+: The Most Important Differences

The Raspberry Pi single board computers (SBC) have been released over the years with incremented model numbers such as the Pi 1, Pi 2 B, 3, 3B+, etc. Now the Raspberry Pi foundation has been updating older models like the A series, as they offer benefits such as a smaller form factor (they can fit…

Blockchain Development: How to Write an EOS Hello World Smart Contract

If you’re not familiar with EOS, it’s a smart contract platform similar to Ethereum.  In this tutorial we’ll be deploying a hello world smart contract to your own local EOS test net. To follow along with the video below, you’ll need to have the EOS software installed, which can be done by following this link.…

Collaborative Robot Use in the Food and Agriculture Industry

Robotic automation has been taken to a higher level as a result of the game changing robotic models from Universal Robots known as the collaborative robots or cobots. These robots can work safely alongside employees since they are easy to operate and portable for faster redeployment to other areas of production. The frequent changes in…

Circuit board with pin plugs on it

How To Secure Loose Jumper Wires/Pin Plugs

Thus far, most of the pin plugs (jumper wires) that I have used for electrical engineering hobby projects have been loose and therefore unreliable. They slip off my development kits, my transistors, among other things. I recently found a solution that will eliminate the problem entirely: flattening them. This is a very simple process, for…

Diabetes Patients Hack Insulin Pump To Make Artificial Pancreas

Continuous Glucose Monitors (CGMs) have been helping type 1 diabetes patients to respond to their insulin needs quicker via continuous monitoring and notifications, but there’s plenty of room for improvement. Incorrect insulin levels can be life-threatening, and so sleeping through the CGM’s alarm is potentially dangerous. For Dana Lewis, this was a problem (usually at…

Metal 3D printer

Metal 3D Printers Will Have Massive Implications

3D printing technology has already shown the world that a fairly small desktop appliance can pop out a number of elaborate items. However, it has been limited to certain materials. Metal 3D printing has historically been cost prohibitive, but now the cost of it has fallen to 1/20th of what it used to be thanks…

A computer the size of a salt grain.

IBM Invents A Computer The Size Of A Salt Grain

IBM has invented a computer as small as a grain of salt, which will cost less than $0.10 to manufacture. It is equipped with hundreds of thousands of transistors, and has processing power equivalent to that of the 1990 x86 processor. This almost-microscopic computer is intended for embedded systems in advanced supply chain management applications,…
