Yes! We believe!
We can design the future in our garages.
Free-range? Grass-fed? How about 3D-printed next to the Nespresso on your kitchen island? That could be the beef of the future, friends. And two German design students have ginned up the latest plans for a slick-looking machine that could make it.
Sarah Mautsch and Aaron Abentheuer, students at Germany's University of Applied Sciences Schwäbisch Gmünd, came up with the concept, which joins other makers of fake animals, like Beyond Meat andModern Meadow. It's called the …Continue
Not too many people like pushing a lawn mower around the yard, but unfortunately, it is a necessary chore. Anti-push-mower advocate [imadethis2014] decided to (as his moniker suggests) make a solution to his pushing-problem. He was a fan of radio controlled devices so it made sense to convert his mower to RC!
The mower itself is powered by an off the shelf battery and has a 21-inch deck. The stock wheels and handle were removed and replaced with a new extruded aluminum frame. Out back are a pair of used electric wheelchair motors sourced from eBay. These drive motors are mounted to the new frame via a pair of aluminum brackets that [imadethis2014] designed and cut out on…Continue
[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 toy.
Codename Colossus is a toy line that is made to order and intended to be artisanal in nature. Each piece will be individually hand-painted and assembled like the HMC Boudicca. While no official prices are posted yet on the site, we assume these are not going to be cheap. In fact, the site states that each piece will have a 2% markup from the previously sold price to help maintain the value of the pieces and control cost inflation. This could be a source of contention for potential buyers.…Continue
Hello Guys! On this tutorial we're going to learn how to use the Ultasonic Distance Sensor HC-SR04, one of the most versatile sensors available. You can use it in several fields, from robotics to industry and much more.

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 module transmits data to a remote receiver connected to a computer from where it is published to the internet.

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 decided to use the dashboard of an actual car.
Leon is repurposing the dashboard of a Volkswagen Polo 6R for ETS 2 with the help of the Arduino Uno and the SEEED CAN Bus Shield, which lets you read and record vehicle diagnostics. Of course, in Leon’s case he’s trying to do the opposite: feed telemetry from the game into the instruments in real time. Leon still has a long way to go, but so far he’s figured out the CAN codes for many of the Polo’s gauges and indicators.…
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 outfitted with over 200 apps that can teach English to kids or keep photo journals. SoftBank, the Japanese cellular megacorp that's selling Pepper, says it's the world's first robot able to intuit human emotions by sensing changes in voice and other things like facial expressions.
It'll sell for 198,000 yen, or about $1,600. What's more, Pepper has its own emotions, a feature that's been added since the robot was initially announced last year. In Tamagotchi fashion, Pepper gets lonely if…Continue
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 and surely many broken props.
The team used an Iris+ for this project instead of the Phantom used by [KATSU] earlier this year, but the principle of the entire endeavor remains the same: fly up against a wall, flick a switch, and watch paint come out of a spray gun. To get the can spraying paint, they modified a can gun to accept a micro servo. This servo is connected to the trigger mechanism of the can gun, and the entire unit is slung under the quad.…
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. Somehow or another, nobody makes pots in this value any more. Luckily the hardware in these joysticks is well documented, and shoehorning in modern components isn’t that bad.
The Apple joystick has a bit of circuitry – a 556 timer chip that reads the values of each pot and converts that into a stream of 0s and 1s for the Apple. The joystick [Quinn] found for her game pad is an analog thumb stick on a neat breakout board manufactured by Parallax. This analog joystick has 10kΩ pots in it, and…Continue
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 a tape delay is simple enough – just run a loop of tape round in a circle, through a record and playback head, record some audio, and send the output to an amplifier. In practice, it’s not that simple. [dogenigt] had to manufacture his own tape loop from microcassettes, a process that took far too long and was far too finicky.
