DIY Glue Gun Build

  Ben Heck uses glue guns alot to put things together. They sure do a good job of quick and dirty strain relief and fixing things in place quickly. With a bit of heat from a big fat soldering iron (one that isn’t used for soldering wires) you can easily release things that were previously glued together. The main part of the DIY glue gun is the heating chamber, Ben

Sydney Mini Maker Faire

  Dave from the EEVblog checks out the Sydney Mini Maker Faire which was held at the power house museum. Quite a few 3D printers and robots driving around. At 5:45 there is a guy who does a brain wave scan of people, combines it with weather data and 3D prints a design that combines the two. At 8:30 you can see some rockets on display outside and a demonstration

Ultrasonic Range Finder with Haptic Feedback called The Bat Hat

  Jeff Buswell, Clifford Chou and Andrew Knauss from Cornell university made a cool Ultrasonic Range Finder with Haptic Feedback called The Bat Hat for their ECE 4760: Final Project.  “For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is

Levitating Spinning LEDs

  Sam writes. “An electromagnet levitates a ring of LEDs attached to a coil. The LEDs are powered using a wireless power transfer from another coil under the electromagnet.  Levitation is achieved using a Hall effect sensor and a proportional controller implemented on a KA7500 SMPS controller. The wireless power transfer system consists a Class E DC/AC inverter operating at 800 KHz.  The LEDs can be rotated to give a

Arduino based Bike Shock Project Allows the Shock to be Programmable

  Lots of things are programmable these days. If you hop into most modern cars you will see switches for things like ride comfort, traction control, performance style etc. When you hop on a bike you would expect the ride to stay consistent. John Brack, David Dang and Broc SommerMeyer from Colorado State have built this Arduino based Bike Shock Project which Allows the Shock to be Programmable. It uses

Friction Heater used to Heat a House

  oilpiggy is heating his 1200 square foot house with his home made friction heater. The heater is simply located in a central area at this time and it naturally radiates heat to the house. He has it plugged into a smart thermostat that controls the run time and temperature of the heater based on time of day. Currently he is heating his house to 75 degrees (with an outside

WiFi Robot

  Check out this great WiFi Robot project that used an app called Wifi Bot Control. “Features Uses WiFi only to control the robot and view the IP Camera stream Configurable camera URLs (up to 3) 3 Joystick Modes: Default, Simple Mode and Orientation Sensor Supports up to 8 additional commands via Command Buttons. Configurable WiFi packet interval. Supports a number of micro controllers – requires WiFi module/capabilities. Sample Arduino
