With three kids, including himself, [Dave] faced the very real likelihood of someone absent-mindedly leaving the garage door open and being robbed blind. Rather than installing some plebeian solution, he compiled a feature list. And what a feature list it is!
The garage door needed to notify him of its status with strategically placed LEDs around the house, and give him full control on his devices. He wanted to open and close it using his existing key-code entry system. Lastly, it would be extra-cool if he could add some biometrics to it; in this case, a fingerprint sensor.
The core hardware is the staple Arduino augmented with a fingerprint module, a touch screen, some vitamins, and a WiFi break-out. He also worked up some casings in tinkercad: one for the indoor hardware, another with a flip cover for the outdoor fingerprint scanner.
We think [Dave] has accomplished what he set out to. We can just picture the would-be-thief staring at the finger print scanner and moving their operation one house over where the world is simpler. Video after the break.

Every year, more than 30,000 people are killed in motor vehicle accidents in the US, and many many more are injured. Humans, in general, aren’t great drivers. Until dependable self-driving cars make their way into garages and driveways across the country, there is still a great amount of work that can be done to improve the safety of automobiles, and the best hope on the horizon is Vehicle to Vehicle communications (V2V). We keep hearing this technology mentioned in news stories, but the underlying technology is almost never discussed. So I decided to take a look at what hardware we can expect in early V2V, and the features you can expect to see when your car begins to build a social network with the others around it.

Waking up at 5:30 in the morning. [Mark Stead] didn’t like the idea either when his chickens started crying to be let out. One simple solution obviously is to eat the chickens build an automatic door opener. The mechanism starts out with an old style mechanical alarm clock, add a geared motor with some creative switch work to pull open the door, weather proof the entire thing, and done. [Mark] even modified the setup later to work with vertical doors. No MCU required for either.
Pair this with an automated feeder system, egg gathering and cooking setup, and you’re half way to having your breakfast ready for you when you wake up in the morning – around noon like the rest of us.
[MC] realized he had forgotten about an order for 2000 cut wires that was now due in a few days. Rather than dropping everything to complete the task, he whipped up this machine to cut the wires for him. A PIC 16F628 board drives a couple of battery-powered drill motors. One of them powers two lawnmower wheels for the feed, and the other turns a pin that squeezes the wire cutters. It’s not as advanced as the cutter/stripper from last year, but it gets the job done.
After the break you can see it does what is intended. The final product took about $80 and 12 hours of his time to build. [MC’s] planned improvements include more accurate wire measurement, plus an LCD and button based user interface.

[Carmine] let us know about his team’s Automated Football Launcher. Their goal was to combine a football launcher with motion tracking, to allow a player to practice running and catching with the perfect throw. Unfortunately, and we’re not quite sure when, they ended up changing out the Jugs machine for an air cannon, which resulted in the use of foam footballs and the loss of throwing factors such as spiral. Somewhat defeating the purpose but we’ll let it slide; only because we know its going to be shooting potatoes eventually.
The project comes together by using two cameras giving distance and color tracking, combined with a rotating platform (and the best use of garden hose ever), an accurate set-top for their launcher. As seen in the video after the jump, it works out quite nicely. Continue reading “Perfect spiral, every time”
[Dmritard96] built this automated watering system to keep his garden growing while he’s out-of-town. It uses rain barrels, which capture and store rainwater, as a source. These barrels provide very low water pressure so he’s added a battery-powered pump along with a solar array for recharging. Don’t worry, if the rain barrels run dry there’s a float sensor that will switch the system over to city water and stave off those wilted leaves.
We’ve covered almost every way possible to remotely control a camera setup, from lasers, to Lego, to doorbells, and even having a Nintendo DS run the show. But at the end of the day, what if you want something that’s small, simple, has amazing flexibility for future additions, and most importantly doesn’t take away your favorite game system. [Whiternoise] wrote up an extremely detailed guide on getting an AVR to control your camera. We like the clean look the final product has, and the large amount of possible add-ons is a major plus. What do you look for in a cheap multi-function wireless camera controller?
