Nothing is better for learning or designing electronics than building real circuits. The breadboard is a popular option but it often results in an incomprehensible spaghetti that has no resemblance to the original schematic and is hard to debug. With this project the connections between the blocks are very reliable since the copper strips of…
A hand-held plasma cutter is an excellent tool to have if you are working with sheet metal, but it’s not particularly well suited to making long or repetitive cuts. Which is why [workshop from scratch] worked his usual scrapheap magic and built his own motorized track for making perfectly straight cuts. More info
Our project utilizes two sensors to determine how optimal a plant’s environment is. We will be gauging the moisture in the soil and access to sunlight to output a quantifiable rating of the environment. The output will be in the form of LEDs that light up, where each LED corresponds to each quality, and the…
It’s a great Christmas gift for those people who love electronics. In this project, I’m going to show you how to make this beautiful decoration with all the steps needed. The main components are NE555 and leds. These and others are THT components, that are easier to solder than SMD components. Also, there is no…
Have you worked with ready-made standard 8×8 LED matrix as displays to make scrolled text or to display your Youtube channel subscriber. A large readily available size is LED diameter 5mm. However, if you are looking for a much larger ready-made LED matrix, you may be out of luck. More info
The economies of scale generally dictate that anything produced in large enough numbers will eventually become cheap. But despite the fact that a few thousand of them are tearing across the sky above our heads at any given moment, turbine jet engines are still expensive to produce compared to other forms of propulsion. The…
There are some research topics that fall outside the scope of 5G and should be considered 6G. Terahertz is a good example. The 5G standard is currently looking at using spectrum below 52.5 GHz, and spectrum 114 GHz is slated for Release 18–21 or later. Spectrum above 114 GHz doesn’t have a release assigned…
The long-used 12V automobile electrical system is going to be no more used. Infact 48V technology would allow the implementation of technologies which are not practical in 12V systems, (e.g. micro-hybrid and micro-hybrid) that would reduce the fuel consumption an CO2 emissions. While eVehicles and hybrid technology switched development into the fast lane, the development…
https://www.youtube.com/watch?v=z-25WZe-k1o Bangle.js is an Open Source Smartwatch that you program wirelessly in JavaScript. It even contains Tensorflow AI for microcontrollers to detect gestures! We’ve reverse-engineered an existing smartwatch with GPS and Bluetooth, and are supplying it pre-programmed with the Espruino JavaScript interpreter. All apps, firmware and tools are OpenSource!

We compare eight of BeagleBoard’s best embedded development boards so you can find the perfect fit for your project. BeagleBoard.org is dedicated to bringing advanced embedded development to your fingertips with their high-performance, community supported and open-source single board computers. Our engineers compare eight of their most popular dev boards and recommend applications for each. …
Paul from Litiholo wrote us to show off a little project they’re doing for Halloween. They’ve made this little spooky skeleton hologram in a casket that flashes to life when someone hits the doorbell. Look, we know that this is pretty much just an ad for their DIY hologram kits, but we were passing this…
