When we first heard the parts list for this project, we weren’t too impressed. It has an iPhone connecting to an IObridge etc… But then we heard the next, and most important part, an air cannon and an assortment of beer. We were sold. As you can see in the video after the break, a fancy iPhone interface lets you select your beer, then dispense it into the cannon for delivery. The next step is to aim using a web cam mounted at the cannon and let ‘er rip! The beer is fired across the room and into your hands. We suspect that the amount of cranial injury, holes in the drywall, and shattered glass will greatly increase in frequency as the night goes on. Awesome.

Here’s a fun video tour of a light testing facility. Admittedly, its not as fun as watching cell phones get abused, but it is interesting. The video is only about 6 minutes long, and is mostly a narrated slide show, but is full of information. There’s plenty to learn about the bulbs themselves, as well as the testing procedures. What you can see above is a box full of LED testing units.
Just one look at that banner image and you’ve got to be thinking “that’s old”! This 1970’s era home made calculator used a 4-function calculator IC that was quite advanced for its time. The only problem is that the chip couldn’t do anything other than calcuations, which left it up to the maker of this dinosaur to get the display and keypad working. Circuit boards were made by drawing on copper clad with resist marker. These controlled the VFD digits for the IC’s output and also fed it the user inputs.
Gone are the days when a phone would last you a lifetime and enter the days of glass covered mobile phones built to be sexy and sophisticated. With these new phones come new testing methods. Companies like Nokia are still dedicated to making the best phones possible and making them durable through vigorous testing. The example shown in the article, is simulating a phone dropping from a shirt pocket onto the floor. Nokia claims to use 200 endurance tests encompassing temperature, extreme usage (use this button pusher for you own test), physical drops, and exposure to humidity on each new model in their product line. Makes one wonder what other companies are using for their endurance tests. There’s video of the Nokia N8 Drop Test is after the break, and don’t forget to leave a comment if you know about other interesting test methods.
