Thanks to Circuit Specialists for sending in this 3 chanel power supply. The Hantek PPS 2320A sure packs in a ton of features for the price. The video below goes through the unboxing of the power supply and a quick run through its features. Overall it functions quite well, there are a few questions that need some clarification. I will have a look through the manual and reach out
 Thanks to Mike Douglas for sending in his build details on these Cheap DIY Noise Canceling Headphones. Sometimes the best solutions don’t need to be expensive. “Mike Douglas wrote: OK, insanely easy, insanely simple. I needed some good noise canceling headphones so I could listen to music while working in my wood shop. I didn’t want to spend hundreds of dollars on commercial brand DJ Ripmaster whoever headphones
  The Sand Noise Device looks almost magical in operation when you first have a look at it running. The system interacts with users placing small cylinders of light in different places on the interactive sand filled box. A computer watches how the users are interacting and displays interesting effects based on what the users do. The most interesting portion is that it has depth awareness which means that
This Termite-Inspired robotic system is quite interesting. Just like tossing a bunch of construction people onto a job if one of them calls in sick the job will still progress that day. But in a typical robotic assembly line if the robot that does a particular step breaks down the entire line is down until that robot is repaired. Just imagine tossing a bunch of generic robots into an
The Pnuematic Rocket Man built by Rodger Cleye used a fire extinguisher fill of air to launch the rocket man high in the air. A camera on the man captures the view! “The pressure is gated by a solenoid actuated sprinkler valve. The valve solenoid is switched through an N- FET that is given a 500mS pulse from the AVR microcontroller. The sprinkler valve output is adapted down to
