      Adarsh Jayakumar, Timon Amirani and Cameron Boroumand developed a Super Secure 4 Factor Lock Box Project for their Cornell University ECE 4760 final project. It uses a typed code, 3 pots set to a specific value, a knock senso...

  Engineering Explained goes into some details about how CVT Transmissions work. Love them or hate them it is an interesting piece of tech.   “A continuously variable transmission (CVT) (also known as a single-speed transmission, step...

  NYC CNC has built a CNC machine that is accurate and made from inexpensive parts.   “Products used in the video: GRBL Alternative for Arduino CNC: http://amzn.to/1C4KZxt Dial Indicator: http://amzn.to/1DuvGQC Indicator with Mag Base...

  When you need a Waveform Generator but just have a Record Player the obvious solution is to create a Waveform Generator Record Player.  This creation uses a 3D printed head for the record player arm and has some simple optics mounted. Simil...

    The Tesla Gigafactory is still being built. It is huge but the building will be much larger when completed. Tesla and Panasonic are in a joint venture in this building. Full production is slated for 2018. Full production will be 500,000...

    Looking for a clock build? This DIY Circular Stepper Motor Clock looks like fun and the parts would be very inexpensive.   “The idea behind the clock is a circle with a circumference of 72cm (28.3465 inch’s) that ticks...

  Automating crop harvesting is one farming duty that robotics is good at but dealing with animals that are lose in a field is another story. The SwagBot is a robot that will soon be tending to the animals in the field. Via: IEEE Spectrum “...

  This might be the time to jump onto the 3D printer bandwagon. The place that provides cheap good quality cables looks to now be the place to pick up a cheap and reliable 3D printer. At $200 it has some features that you wouldn’t expect t...

  HARRIS’ ELECTRONICS is developing a prototype set of Smart Glasses. This is not an easy task! You can read about the development challenges here. Thanks for the tip James. “The glasses themselves are based around an STM32F051K8 mic...

  Jeremy Blum built this Custom Word Clock. It has lots of non electronic parts such as the great looking case. Good thing Jeremy is no longer at Google and is now working at Shaper with use of a wood working shop. We have seen lots of word cloc...

    Check out these Water Droplets Captured using a High Speed Camera Rig. This system uses an Arduino to activate a solenoid, the solenoid releases a drop from a water container mounted at a specific distance above the table. The water fa...

  Bil Herd goes through a great Introduction to Analog to Digital Conversion. These days it is very simple to grab an analog reading and use it with a microcontroller with ease. This is because modern microcontrollers often have one or many ADC...

    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 op...

  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,...
