The Huge LED Display Ultrasonic Range Meter

Have you ever thought of building an ultrasonic range meter before? Oh, you think it’s hard to develop this tool, then you should spend a few minutes and read this on… Frankly, ultrasonic range meter is a PIC-based project, where the heart of this stuff is PIC16F873. The ultrasonic signal, where is always received with the reception sensor is amplified by 1,000 times of voltage with the operational amplifier with two stages. It is 100 times at the first stage and 10 times at the next stage! In general, the positive and negative power supply is being used for the operational amplifier, and the circuit will work with the single power supply of +9V. Some of the parts that needed to make this ultrasonic range meter are: Sturdy case: You… Continue reading

Is The Time For Back to The Future

Did you know that a physicist, William Higinbotham, invented the world first remarkable computer video game, “Tennis for Two” in the year 1958? The purpose for this design is for an exhibition to improve the lackluster visitors’ day at the darn boring laboratory. This “Tennis for Two” concept is based on a tennis court, where its shown on an oscilloscope screen. The oscilloscope will allow the two players to toss the ball to each other continuously. There are two controls in each controller, where a button and a knob. You can hit the ball anytime you want, when the ball is on your side of the net by just hit the button. The function of the knob is to choose the angle you want the ball to be hit. Ok,… Continue reading
