Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.
Joe Menard had many needs for IOT devices in his life, he is an electrical engineer but needed fill in lots of programming knowledge to get his ideas to come to life. He started at a very low level even building a switch mode power supply, with 170 volts on board trace spacing was something that was very important. For the enclosures he didn’t simply buy something and stuff his
Using some Arduinos and a few other electronic bits this HP Scanjet 4C is made into a musical device by “playing” the stepper motor. The result is one of the best stepper motor musical items I have seen. “You may of heard of a popular flat bed scanner named the HP Scanjet. This scanner had a hidden command set within the Scanner Control Language which allows you to send
You have probably never considered how many peeps would need to be between you and a 50 cal bullet to save your life. Just in case this situation ever arises this video will help you stay protected! Not very scientific but you can see the cool result at 1:44.
Engineering Explained goes into some details about how CVT Transmissions work. Love them or hate them it is an interesting piece of tech. “A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios. This contrasts with other mechanical transmissions that
This MASERATI-POWERED, 470 HP, MOTORCYCLE has some power to spare but I am not sure how easy to ride it would be. “The Lazareth LM847 has four wheels and a Maserati V8 engine. It’s exactly as insane as it sounds, and it looks crazy too. Yours for €200,000. Beyond the ludicrous motor, the LM847 forgoes a standard transmission in lieu of a single-speed chain gearbox, which means all you
If you are looking for new ways of getting your Arduino gear to become productive why not try programming it as a state machine. Via: Electronics Labs “Did you ever program an Arduino? Have you ever been worried about complex control flows written in pure C? Maybe you have already heard of statecharts and state machines? YAKINDU Statechart Tools for Arduino is based on Eclipse, YAKINDU Statechart Tools, and
