LED Snowflakes by Mike Harrison

at 10:26 pm. Filed under DIY Hacks, Electronic Hacks

 

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.

How to Build IOT Devices – Talk by Joe Menard

at 11:33 pm. Filed under DIY Hacks

 

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 circuit into it, he custom designed it and 3D printed it.

HP Scanjet 4C Keytar

at 5:50 pm. Filed under Computer Hacks, Electronic Hacks

 

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 musical notes directly to the stepper motor. This is a tedious method where you have to enter the notes and durations manually into a text file (similar to G-Code on a CNC Machine). I have always used and will always use this method for my Old School music videos however I wanted to try and build a MIDI controlled stepper motor.”

Slow Motion Peeps vs 50 cal Bullet

at 5:49 pm. Filed under Crazy Hacks

 

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.

CVT Transmission Basics

at 5:49 pm. Filed under Cool Gadgets

 

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 offer a fixed number of gear ratios. The flexibility of a CVT allows the input shaft to maintain a constant angular velocity.”

MASERATI-POWERED, 470 HP, MOTORCYCLE

at 4:43 pm. Filed under Insane Equipment

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 really have to do is hold on. Top speed hasn’t been announced but if the Tomahawk’s 200-plus-mph figure is any indicator, the LM847 should be in the same ballpark.”

Arduino State Machine

Statechart-Platine-Arduino

 

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 the Eclipse C/C++ Development Tooling (CDT). It sets up an initial project containing an empty statechart that you just need to fill with your own ideas. The only part that you still need to program on your own is the connection between the statechart and the hardware, i.e. initializing the hardware and updating the state of the hardware depending on the state of the statechart and vice-versa.”
