18 Year Old Computer Collector Buys a IBM z890 Mainframe

  At 18 years of age he has already been collecting for years. Most of his collection are things like Commodore and Apple computers. These can sit on a shelf and be moved around with ease. When he saw an IBM z890 Mainframe up for grabs he jumped on it. With a bit of excavation he was able to get it into his parents basement.  

IOT Long Runtime

    With the adoption of IOT long runtime on battery power is something that is a huge concern. We don’t mind charging our smartphones daily but if we have a dozen IOT devices in our home we would like them to be invisible and just operate for as long as possible without needing attention. Andreas Spiess has done some research using the popular ESP8266 and a variety of batteries. In his test

Huge Welder, High Current Tester

  John Ward shows us his new test device. Not exactly a bench mounted piece of gear! This Oil Filled Oxford Welder can be used in cases where you need to pump out some serious current, this is ideal to test to destruction items such as wires, extension cables, plug in connections etc. JW has performed many of these tests in the past. Photonicinduction has taken a look at the inside of one of these

Carbon M1 Printer Demo

  Tested got a look at the new Carbon M1 3D printer. They are still a bit secretive on some of the special sauce that differentiates it from the competition but their technology allows the system to print very quickly. It looks almost magical since the part grows out of the media dish. This is because the projection system is at work in the base and works by interacting with the

Name the Thing Contest – 296

    The prize this week is a HMC5883L Triple Axis Compass Magnetometer Sensor so you can add some directionality to your next project. This contest will run for one week (May 23 – May 27, 2016). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to

Spring 2016 Cornell University ECE 5760 Advanced Microcontrollers Final Projects

  It is that time again! There is a new batch of Cornell University ECE 5760 Advanced Microcontrollers Final Projects. If you have done any PID work in the past the FPGA controlled Magnetic Levitation by Gautham Ponnu, Ryan Land, Nathan Spallone should be of interest. They are using a Altera DE2-115 FPGA board to monitor and control a steel ball about 1mm above the position sensor with great accuracy. “The LDC1000

SOLAR Powered Plane

  Prometreus has a great concept here. This plane has autopilot and a camera to capture the trip. With a 6 hour 200km range you can certainly cover a huge area. “A SOLAR powered RC plane flies over 6 hours, only powered by the sun. The plane travels a distance of over 200km. It is self sufficient like the solar impulse system. ”
