Vodka Vending Machine

at 2:39 pm. Filed under Cool Gadgets

 

Ben Armstrong built this interesting Vodka Vending Machine.

“Designed to dispense alcoholic beverages in night clubs this project was design and built by myself and another team mate. Arduino hardware was used to program the device which include a stepper motor, an infra red sensor, two solenoid valves, an LCD screen, buttons and a coin collector.”

The MIT Biomimetic Robotics Laboratory has been working hard on the MIT Cheetah Robot. Deborah Ajilo, Negin Abdolrahim Poorheravi,John Patrick Mayo,Justin Cheung, Sangbae Kim, Shinsuk Park, Kathryn L. Evans, Matt Angle, Will Bosworth, Joao Luiz Almeida Souza Ramos, Sehyuk Yim, Albert Wang, Meng Yee Chuah, and Hae Won Park are members of the huge development team. Why so many team members? This is not a simply problem to tackle, as you read through their post you will see that there were a number of challenges that they needed to overcome in the development of the system.

“Now MIT researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah — a sleek, four-legged assemblage of gears, batteries, and electric motors that weighs about as much as its feline counterpart. The team recently took the robot for a test run on MIT’s Killian Court, where it bounded across the grass at a steady clip.

In experiments on an indoor track, the robot sprinted up to 10 mph, even continuing to run after clearing a hurdle. The MIT researchers estimate that the current version of the robot may eventually reach speeds of up to 30 mph.

The key to the bounding algorithm is in programming each of the robot’s legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward. Sangbae Kim, an associate professor of mechanical engineering at MIT, hypothesizes that this force-control approach to robotic running is similar, in principle, to the way world-class sprinters race.”

RC Plane delivers Quadcopter Drone which delivers Quadcopter Drone which delivers Quadcopter Drone which delivers a stick of gum!

The guys over at Flight Test were thinking about the drone delivery systems that we might see in the near future. They wanted to see how far they could push it. They strapped the stack of quad copters onto their Kraken plane, which had an Electrohub quad on it, which had a QAV250 Lumenier on it, which had a Proto X on it which was set to deliver a piece of gum! Of course everything is outfitted with cameras so we can get a really close look at everything unfold.

Cassette Tape with Hidden MP3 Player

 Cassette Tape with Hidden MP3 Player_4

 

Remember cassette tapes? These were small devices that held a spool of plastic covered in rust and allowed us to record audio onto,  if you were brave you would even store your Commodore 64 programs onto them. This Cassette Tape with Hidden MP3 Player project looks just like a Cassette Tape but has a Hidden MP3 Player inside to allow you to hold a full case full of tapes worth of music. The user interface is interesting since it uses the reels to interface with the internal player.

Spooky Automatic Halloween Door Knocker

at 11:44 am. Filed under Cool Gadgets, DIY Hacks

 

There aren’t much details on this Spooky Automatic Halloween Door Knocker project by WAGfilms. But just by looking and his brief description we can get enough info to build our own. I think this is a great project idea that can be used for more than just a cool Halloween prank.  He is using an Arduino Pro Mini as the brain of the system and it runs off some AA batteries. We can see that there is a PIR motion sensor that has been mounted in the forehead of the beast which will is ideal to send a signal to the arduino that someone has arrived. Some spooky LEDs are used to make the eyes glow using a nice smooth but quick ramp on. This can be done using one of the PWM pins on the microcontroller. But the best part is the automatic knocking of the door! Stick a servo motor in there and connect it to a single spare I/O of the controller and you are done. The servo will need to be quick large depending on the weight of the knocker though since it needs to move it quite vigorously!

APRS – Automatic Packet Reporting System on a Raspberry Pi

at 11:15 pm. Filed under Cool Gadgets

 

If you need to keep track of the location of some things like your car or your service workers you can sign up for a service that uses cell phones and GPS or you can use the APRS which stands for Automatic Packet Reporting System. Jim Whiteside demonstrates how he is using a Raspberry Pi to gather data, decode it and plot it on a map. Since the service can also send text messages I am wondering if this might be an interesting way to send some small amounts of data occasionally from one location in a city to a base location. Something like high water alarms and temperatures a few times an hour. I am not a ham operator so I am not sure if this would be frowned upon as a use of the system though.

If you are looking to get some additional information on APRS you should have a look at the videos below. If you like reading text tapr.org also has a great resource.

Bus Stop Video Game powered by a Raspberry Pi

 Bus Stop Video Game powered by a Raspberry Pi

 

If you are tired of waiting in a boring bus shack waiting for your bus I bet you wish the guys from Norwegian Creations pimped your bus shack!

“The system consists of a Raspberry Pi running RetroPie and a (somewhat modified) Makey Makey. Because the controls needs to be available for the users they need to be somewhat environmentally sealed. Therefore, by using a Makey Makey and some aluminium tape, we created a robust and waterproof “touch” panel on the outside of the booth. The WS2812B led strip is controlled by the Makey Makey, and because it’s open source and Arduino compatible it was easy to modify the source code to also control the led strip based on key strokes.”
