USB 3.2 is a standard for compatible ports and connectors, which defines how a connection between them would work. The USB Implementers Forum (USB-IF) announced this specification back in 2017. The second upgrade of the third major iteration (originally known as USB 3.0) in the Universal Serial Bus (USB) family. This standard brings a significant […]

latforms are both useful to know at a professional level, and simply fun to engineer and code. The 2022 Complete Raspberry Pi & Arduino Developer Bundle helps everyone from coding experts to new engineers get the most from these popular tools. Edouard Renard, the bundle’s instructor, designs his courses to be learned one step at a time,

Back in the old days, we didn’t have fancy digital clocks. No, we had good analog clocks with a big hand and a little hand, and if you wanted to know the time you had to look at the clock and figure out which number each hand was pointing at, or kind of pointing at.
UNIQUE CLOCK IS ALL HANDS, NO DIAL, AND DOES THE WORM Continue Reading
We feel bad when we see a retrocomputer project and think, “Hey! That’s not that old.” But, usually, when we think about it, it really is. Take the Penkesu. It looks like one of the little organizer computers that were popular — ok — a long time ago. Inside is a Raspberry Pi Zero 2W, a
A team of students from the German Saarland University in Saarbrücken, has created a unique handheld printer using an Arduino Mega 2560 called the Print-A-Sketch. The small handheld printer is capable of printing conductive ink images and will automatically correct any user errors during the print process, as well as providing a wide-ranging drawing tools to create any designs you

[Electronoobs] built a coil gun and the obvious question is: how fast is the projectile? To answer it, he built a chronograph suitable for timing a bullet. The principle is straightforward. A laser and a light sensor would mark the entry and exit of the projectile over a known distance. As it turns out, there are some
Measuring air quality at any particular location isn’t too complicated. Just a sensor or two and a small microcontroller is generally all that’s needed. Predicting the upcoming air quality is a little more complicated, though, since so many factors determine how safe it will be to breathe the air outside. Luckily, though, we don’t need
Universal remotes are a handy tool to have around if you have many devices that would all otherwise have their own remote controls. Merging them all into a single device leads to less clutter and less frustration, but they are often not truly “universal” as some of them may not support every infrared device that
A magnetometer is an electronic device capable of measuring magnetic fields or magnetic dipole moment. Magnetometers are widely used for measuring the Earth’s magnetic field, in geophysical surveys, to detect magnetic anomalies of various types. If you fancy building your very own DIY magnetometer you may be interested in a Arduino project published to the Instructables website by maker Markus Opitz. His

Introduced in 1984, the Psion Organiser series defined the first generation of electronic organizers or PDAs (personal digital assistants). Even though these devices are now over 30 years old, the Psion Organiser scene is alive and well: with new hardware and software is still being developed by enthusiasts the world over. One of those enthusiasts
