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.”

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

at 9:28 pm. Filed under DIY Hacks



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.”

Waveform Generator Record Player

at 5:57 pm. Filed under Cool Gadgets, Electronic Hacks



When you need a Waveform Generator but just have a Record Player the obvious solution is to create a Waveform Generator Record Player.  This creation uses a 3D printed head for the record player arm and has some simple optics mounted. Similar optics that would be used in a line following car feedback the pattern. Swapping the disk changes the pattern.

“The light sensor is a 3 mm Everlight ALS-PT204-6C/L177. It was chosen because it responds to standard visible light, rather than infrared. I want it to see what I see.

The light sensor connects to +5VDC and to the middle pin of trimpot R3 (100 kΩ). My trimpot was dialed to about 20 kΩ, but you’ll need to adjust it based on the light conditions and distance to the target. The goal is to create as large of a signal as possible, with a compromise between flattening the top of the wave and the bottom of the wave.”

DIY Flexible Circuit Board

DIY Flexible Circuit Board


DIY PCBs are quite simple to make these days but DIY Flexible Circuit Boards are still something that is not easy and also not common in most PCB production houses. With this technique you can now dabble with flexible boards in your next project.

Thanks to Wheedal for the tip


“A fairly new elastomeric rubber filament is now available that sticks quite well to copper. It is called Ninjaflex. In fact, it sticks quite well to almost anything including acrylic, blue painters tape, and glass.

A circuit board pattern can be drawn in a free program like 123D Design and then extruded to a thin thickness and saved as an STL file. It can then be printed on top of a thin copper clad board or plated conductive fabric: step 1 pic. It can then be etched in the standard way with a Ferric Chloride solution.”
