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.”

Makers can Design for NASA and Win Millions

at 10:45 pm. Filed under Crazy Hacks

 

Caleb Kraft interviewed Sam Ortega from NASA, Sam explains how the prize competitions at NASA work. Anyone can submit designs for their competitions but only US citizens can win the prize money.

“NASA Centennial Challenges were initiated in 2005 to directly engage the public in the process of advanced technology development. The program offers incentive prizes to generate revolutionary solutions to problems of interest to NASA and the nation. The program seeks innovations from diverse and non-traditional sources. Competitors are not supported by government funding and awards are only made to successful teams when the challenges are met.”

Guess what this isn’t Contest – 9

at 4:21 pm. Filed under Contests

guess 

 

This week we are doing another fun guess what this isn’t contest, we are up to 258 of the name the thing contests and it’s time to switch things up a bit. to  The prize for the lucky winner is a is a cool RFID RC522 Reader with an SPI interface to easily add to your next project,a skeleton watch, an Iain Sinclair credit card knife, an SD card reader interface and an Arduino Pro Mini. Simply reply in the comments what the device pictured above isn’t. Come up with something that is remotely plausible but not what it really is and sell us on it. Make your entry funny, crazy, weird… Just use your imagination. You can enter more than once if you come up with more than one thought. With a short vote the best comment will win the prize.

Have a look at my first comment for an example entry.

This contest will run for one week (September 20, 2014 – September 26, 2014) . Ending time is based on central standard time.

Below is a pictures of the prizes (there will be one winner).

Build a Custom Computer that is Theft Proof

 

If you have ever been the victim of a break in you know the sick feeling that someone was going through your belongings and helping themselves to what appealed to them. If you want to ensure that your computer isn’t something that is part of the burglars loot bag have a look at the custom computer case that built, he gutted an old VCR and crammed in a PC based around a mini ITX board.

“Needed materials:

  • an old VCR case;
  • a Mini-ITX form factor motherboard;
  • a Flex-ATX power supply (it’s smaller than standard ATX power supplies);
  • a 2,5″ hard drive;
  • LEDs and USB/Audio connectors from other old PC case;
  • rotary tool (such as Dremel, or a cheap tool);
  • hot glue gun;
  • glue, zip ties, some pieces of scrap plastic or wood;”

DIY RFID Card Lock System

DIY RFID Card Lock System

 

Shawn McCombs built a DIY RFID Card Lock System for his office. The wiring is a bit quick and dirty but sometimes you just need to get things done. It is based around an ATMega 328 microcontroller and is coded using an Arduino sketch but the controller id hand wired on a breadboard to allow for some customization. Shawn is using the Parallax RFID controller that was designed by Joe Grand (kingpin). Looks like there is a good separation between RFID reader and door control, this is important since with many inexpensive all in one systems the activation relay is built into the reader module. In this case all you would need to do is crack open the reader on the wall and short out the N/O contact to buzz the door strike. If the lock is a fail safe style like a mag lock it is even worse, just knock it off the wall and chop all the wires going to the all in one reader. This will open the N/C contact that is keeping the mag lock energized and unlock the door.

Inside the Commodore PET

at 1:28 pm. Filed under Computer Hacks

 

David Watts got his hands on a Commodore Pet computer. I have never seen under the hood before, and it is quite funny that the case actually opens like a hood on a car including the prop stick to keep it open. David will be attempting to restore the PET so that it works properly again, it looks like the keyboard didn’t stand the test of time very well, there are now more keys not working than working. I am curious what will be needed to bring it back to a fully functional state. I am thinking the caps are long dried out and not doing much smoothing anymore.

MIT Cheetah Robot_4

 

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.”
