Below is video tutorial about how to assemble the crossover network for the TriTrix speaker system. The TriTrix speaker system uses a second order crossover. Second order mean thare are two part coil for each filter. To assemble this, we only need a glue gun, plan board, wire and the electrics components. To assemble it, we can use a plain […]

Below is video tutorial about how to assemble the crossover on the Aviatrix speaker. The speaker system has couple different version that you can build. There are mass loaded transmission line and channel speaker or we can used it as surround speaker at home theater system. There are slight changes in the crossover based on how you going to use […]

This is a video tutorial of ultrasonic security. This tutorial explains how ultrasonic security circuit works. The ultrasonic security circuit consist of two main circuit. First is a transmitter circuit which transmit the ultrasonic signal. And then a receiver circuit, it is used to receive signal from the transmitter. The front of receiver circuit is a signal receptor and the […]

This is video of create teeny tiny solar insect robots. The tiny solar insect robot is called beambots. This beambots is supplied by solar cell. The electricity is made from sunlight heading the panel. Since the electricity is small, the capacitors that is chosen must enough to turn the motor. Beside the solar panel and the large capacitors, the required […]

This is a video of kinetic remote control. This video shows step by step by step how to make a kinetic remote control. A kinetic remote control is a remote that doesn’t need a battery. This remote control using a kinetic energy to operated. To make this kinetic remote control we need a tube, a couple capacitors, diode, wire, circuit […]
