How to jump start a car with AA batteries

When your car battery dies, you can either ask someone for a jump start, or call for some roadside assistance and let them handle the process when they arrive. Those are the most common practices, but what if there was another way?

If you’re the DIY type, your options are not so limited when it comes to jump starting a car battery; assuming…

Do Nothing Machine the precursor to Useless Machines

In the 1940s, a retired clockmaker named Lawrence Wahlstrom found a complex arrangement of gears and began work on what would become the precursor to today’s useless machines. Lawrence’s Do Nothing Machine uses three electric motors and over 700 moving parts to achieve absolutely nothing.

The Craftsmanship Museum,…

Codename Colossus: The HMC Boudicca



[Michael Sng], founder of [Machination Studio], wanted to create a toy line unlike anything the world has seen.  He has recently completed the first production prototype in the  Codename Colossus toy line: the HMC Boudicca. The egg-shaped HMC Boudicca is tank-like with a definite Metal Slug vibe, but it’s almost a disservice calling it a…

Wireless weather station

High schooler spent about a year building up his battery-operated, wireless weather station. Along the way, not only has he learnt a lot and picked up useful skills, but also managed to blog his progress.

The station measures temperature, humidity, pressure and battery voltage, and he plans to add sensors for wind speed, wind direction and rainfall soon. It is powered via a solar panel and can run on a charged battery for a full month. The sensor…

Dashboard in you simulator!

 

Fans of driving simulator games not only play with steering wheels, gear shifters and pedals. Some of them get working gauges to make the experience more immersive. Hack A Day forum member Leon Bataille wanted to have a dashboard for Euro Truck Simulator 2 (ETS 2), but instead of buying or building the gauges and indicators, he…

Pepper, the robot that reads your emotions, will be sold to costumers!



Starting this weekend in Japan, people can buy a talking, person-shaped robot that reads your body language and gets sad when you turn off the lights. You may remember Pepper, the four-foot-tall, 60-pound, talking, dancing, joke-telling robot that guesses users' moods and keeps them company.

Pepper, whose software is open source, can be…

The Trials Of Quadcopter Graffiti

Last April, graffiti artist [KATSU] strapped a can of red spray paint to a Phantom quadcopter, flew it up against one of the largest billboards in New York City, and pressed a button. Now, [KATSU], [Dan Moore], and Adafruit’s [Becky Stern] are trying to perfect a flying can of spraypaint, and they’ve met with some success…

A game pad for the Apple II

The Apple II joystick port isn’t as simple as an Atari or Commodore joystick port. Where the bog-standard Atari joystick is basically just a bunch of switches connected to pins, the Apple II joystick is analog. Weird, and even weirder is the value of the pots in these joysticks: 150kΩ.…

Microcassette recorders become a tape delay



Microcassette recorders are not, in general, incredible pieces of engineering. They do, however, have a strip of magnetic tape, a record head, and a play head. Put two of them together, and you can build your own tape delay.

The basic principle of…

Prevent failed prints with a filament speed sensor

The Arduino relays the rotary encoder data to the computer over USB

If you have used a 3D printer for any length of time, you’ve probably experienced a failed print caused by a clogged nozzle. If you’re not around to stop the print and the nozzle stays hot and full of filament for hours, the clog gets even worse.

For this issue cuddleburrito.com designed a small assembly with a wheel and encoder that measures filament movement. The filament passes under the encoder wheel before it’s fed into…

Robot eyes will benefit from insect vision

               Robot eyes will benefit from insect vision

The way insects see and track their prey is being applied to a new robot under development at the University of Adelaide, in the hopes of improving robot visual systems.

"Detecting and tracking small objects against complex backgrounds is a highly challenging task," says the lead author of the paper, Mechanical Engineering PhD student Zahra Bagheri.

The team of engineers and neuroscientists has developed an unusual…

Porting AnalysIR firmware to Particle’s Photon platform

We have just finished porting our (single source) firmware from a range of other ‘Arduino’ type platforms to Particle’s Photon, having received it yesterday & thought it would be useful sharing some of our experiences for other ‘newbies’. The photon is one of a breed of modern IoT devices hitting the market at relatively low cost. It features a STM32F205 120Mhz ARM Cortex M3 processor running at 120MHz with 1MB flash, 128KB RAM and the all important WiFi. We have been wanting to support…

Diabetes Has a New Enemy: Robo-Pancreas

Now, the diabetes has a new enemy: the artificial pancreas. It links data from an implanted blood-sugar sensor to a computer, which then controls how a pump worn on the hip dribbles insulin under the skin through a pipette. In its fully realized form, the machine would take the patient out…

Simple Infrared PWM on Arduino, Part 2- RAW IR Signals

In Part 1 of this series, we demonstrated how to send signals using simple Infrared PWM on Arduino. In this Part 2 post we look at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal. We have also improved the method shown in Part 1 due to some issues we identified when sending ‘real’ signals versus the ‘test’ signal we…

Watching robots falling down is the best thing you’ll see today



We have some very good reasons to fear our future robot overlords, but this video is proof that we still have plenty of time until we are all enslaved. IEEE Spectrum put together this video compilation of robots falling down at the 2015 DARPA Robotics Challenge.

Robots falling is pretty hilarious. Of course, they probably know the names…

On your phone while driving an electric skateboard



Skateboards are fun, but you have to do all that pesky kicking in order to get anywhere. That’s why Nick decided to build his own eletric skateboard.
 Not only is the skateboard powered with an electric motor, but the whole thing can be controlled from a smart phone.

Nick used a Turnigy SK3 192KV electric motor to…

3D Printed Toy Knocks Finished Prints Off the 3D Printer: PLAss Joe

Despite the advances in hardware and software and lots of guides online, 3D printing can still be tedious, even for experienced makers. One of the hassles of 3D printing is that your print can get stuck on the print bed; you’ll have to wait for it to cool then gingerly pry it off.

Tyler Anderson came up with a silly solution: punch his…
