The MB Electronics Pocket Simon game has a very simple circuit thanks to the inclusion of a custom MB Electronics processor (the MB4850) which performs nearly all of the functions for the game. The only other significant piece of electronics is a SN75494N chip which interfaces the processor to the light bulbs and the built in piezo buzzer. The a

im of this exercise is to reverse engineer the Pocket Simon game so that it can be replicated as accurately as possible using modern components (or even reproduced entirely in software). This includes analysing the hardware (how it is built and how it works), the software (including timing, note frequencies, game modes, light sequences, etc. ). Since the processor of the Pocket Simon is the same as found in the full size Simon all information contained in this document are relevant to both (I chose the Pocket Simon since I didn`t want to risk damaging my full size game). Single Player The game generates a sequence of lights and sounds which the player must follow, the sequence grows by one colour every turn and ends when the player makes a mistake or repeats the maximum number of colours in a sequence (which is dependent on the skill level setting) Multi Player (game 2) The game begins with Simon displaying a colour, the first player must repeat the colour and then select another colour, subsequent players must enter the current sequence and then add one more, the next player then selects the sequence of colours entered so far and then one more and so on until a player makes a mistake (or a sequence of 31 colours is achieved). Multi Player (game 3) This game is identical to game one, however each player owns one or more colours and is responsible for pressing it during the sequence. If a colour is incorrectly selected...
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.....
