“Ever wondered if you could control things with the power of your gestures? Ever wondered if with the help of sensors you could make things look as though it works by magic? Well meet CUBEX, an Arduino sensor safe that …
“The 74181 ALU (arithmetic/logic unit) chip powered many of the minicomputers of the 1970s: it provided fast 4-bit arithmetic and logic functions, and could be combined to handle larger words, making it a key part of many CPUs. But …
“Something that can automatically generate a turbine or propeller? This OpenSCAD script does just that! Generate very quickly a parametrised turbine or propeller. Arguably the best one on thingiverse? t is quite complete, here I list its features: Clockwise/ Counter …
“Single Cylinder Air Engine Smaller Edition is the smaller sibling of my previous Single Cylinder Air Engine here: https://www.instructables.com/id/Single-Cylinder-…. While Single Cylinder Air Engine Smaller Edition was designed as a test platform for another design …
News As Moore’s law nears its physical limits, a new generation of brain-like computers comes of age in a Stanford lab
“For five decades, Moore’s law held up pretty well: Roughly every two years, the number of transistors one could fit on a chip doubled, all while costs steadily declined. Today, however, transistors and other electronic components are so small …
“Build a great sounding FM radio with a cool display using an Arduino Nano and the Sparkfun Si4703 FM tuner breakout. As a kid, I used to build AM radios but never quite managed to build FM radios. They were …
“The success of the ESP8266 from Espressif Systems is undeniable. It is a powerful microcontroller with built-in Wi-Fi capabilities and is readily adaptable to a multitude of uses in the rapidly growing IoT (Internet of Things). One of the few …
“One of the interesting usage possibilities for the RasPiO InsPiRing system is illuminated signage. What could be better than flashy, blinky, multi-coloured signage? Well, not much really? So I decided to make an arrow out of two straight 8s and …
“This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user about the battery’s state …
“O2 sensors do wear out and eventually need to be replaced. The performance of the O2 sensor tends to diminish with age as contaminants accumulate on the sensor tip and gradually reduce it’s voltage. This is caused by substances …
