Airbus To Halt Production Of The A380; Goodbye To An Engineering Triumph

February 15, 2019 by 50 Comments

Eleven years ago, the Airbus A380 entered commercial service with Singapore Airlines. In the time since then it has become the queen of the skies. It’s a double-decker airliner, capable of flying 550 passengers eight thousand nautical miles. Some configurations of the A380 included private suites. Some had a shower. This is the epitome of luxury, a dream of flying with long-stemmed glasses, a movie, and a pleasant dream in mid-air.

Now, after the cancellation of A380 orders by Emirates, Airbus has announced it will end production of this massive, massive plane. No, it’s not the last flight of the Concorde, but it is the beginning of the end of an era. The biggest and most impressive planes just aren’t economical; it’s possible to fly three 787s across the globe for a single flight of an A380.

High Voltage Etch A Sketch

January 22, 2011 by 12 Comments

What do you get when you mix a simple X/Y plotter, a Flyback transformer, and an unhealthy disregard for safety? Possibly the worlds most dangerous jumbo Etch a Sketch! [Kalboon] started off by making an imprecise X/Y movement device, similar to a CNC machine setup, but with less emphasis on precision. This rig is powered by some commonly salvagable materials, including an old scanner, a remote control car, and some hobby servos. We like this approach because most of these materials could be scrounged from a parts bin, surplus sale, or craigslist for little to no actual cost. The flyback transformer comes from an old TV or monitor, though if you have common sense safety concerns, we would recommend just mounting a dry erase marker and a dry erase board to substitute out the high voltage bits. For people wanting a low cost introduction project to making a CNC or Makerbot style build, this isn’t a bad place to start.
