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
Releasing a large charge all at once can have some fantastic results. Lemming from the EEVBlog forum has taken 16 X 2500V 40uF capacitors all connected in parallel, this provides 2180J potential. They are able to provide about 4000A at 2500V for a short time! The video below shows what happens when you pass too much current through a pencil.
The prize this week is a relay module to get your next project started. This contest will run for one week (Mar 26, 2016 – Apr 1, 2016). Ending time is based on central standard time.

This is a neat desktop project that will help you get rid of some stress by firing you own mini canon. The design is well thought out and the video goes over the build in great detail. The system is quite simple, an electrical current creates some heat and fires some Nitrocellulose. The end result looks fantastic and would fit well on the edge of your desk ready for battle
