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 […]
Read moreThis 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 […]

This is a noninverting amplifier circuit. This circuit amplify the input voltage with the same phase with output voltage. This circuit has infinite input impedance, but using 741, the input impedance would be hundreds of megaohms. The output impedance is a little, in fraction of an ohm. Here is the schematic diagram of the circuit: This circuit is made for […]

This is a Inverting amplifier circuit. This circuit is used to amplify the application that requires large(closed-loop) voltage gain since it has low input impedance. The output of this circuit is an amplified signal with different phase wit the input. This circuit uses a feedback. Here is the schematic diagram of the circuit: The R1 is 10K and R2 is […]
