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

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
We featured the MakiBox here before, taking about their inexpensive 3D printer (still the cheapest as far as I know). They have two models, one that goes for $200 and one that goes for $300. So what happens to your company when you offer a hot product at this kind of price? You get lots of orders and need to ramp up very quickly. They have a number of
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
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. Â 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. Â The LEDs can be rotated to give a
Gauri Nanda, who is well known for her rolling alarm clock called Clocky has teamed up with her friend Audry Hill to build a new product called Toymail. It’s a fun way for people (parents, grandparents, aunts and uncles, etc) to stay in contact with kids. The cute toy mailbox contains electronics which allows it to send messages back an forth to a smartphone app. If you hurry you
