Tennis for Two presented a tennis court shown from the side on an oscilloscope screen, where handheld controllers allowed the two players to toss the ball to each other. Each controller had two controls: a button and a knob. With the button, you could hit the ball at any time of your choosing when it was on your side of the net, and with the knob you could choose the angle at which the ball was hit.

The game was based on the best contemporary technology: analog electronic computers built out of op-amps, relays, and the occasional transistor. It took Higinbotham and his technicians several weeks to design and build the game. Of course, some things have changed over the last 50 years. Using convenient modern electronics, we have designed a functional and playable replica of the original that can be put together by a hobbyist in a couple of evenings. You can watch the video of our recreation on YouTube or embedded here: So, the next question you might ask is, How do you build this And, if that is in fact what you`re asking right now, you`re in the right place. The quick answer is, with an oscilloscope, an AVR microcontroller, and a digital to analog converter. Ready to get going Before we start, let`s be clear that this is not a tutorial in how to build an oscilloscope. Tennis for Two is supposed to display on a scope, so beg, borrow, or buy one if you don`t have one handy. Older low-end analog scopes like mine (a Hameg!) usually go for $50-$150, and if nothing else, you can always make a Scope Clock out of it later. There are three parts to the electronics that we`re building. First, there is the AVR microcontroller the brains of the outfit. The specific variety that we`re using is the ATmega168, the same chip used in (for example) the Arduino platform. Secondly, there are two handheld controllers that connect to the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
