Install your fresh mod board into your FDS drive mechanism. You need to cut two traces and solder 8 wires to various points on the board. If you have installed a console modchip before, this step should be a piece of cake. Since the Famicom uses 1980s technology, the circuit board traces and solder points are big and clear to see, and therefore

easy to solder on with basic to intermediate soldering skills. With the drive mechanism out of the case, flip it around so that its bottom side faces up, and remove the three Phillips screws that hold the bottom metal plate together (one of the screws doesn`t hold the metal plate at all, don`t remove that one). Remove the metal plate to expose the circuit board underneath. Rotate the disk drive mechanism so that the disk card slot faces away from you and the power board connector points at you (in the case of the above picture, rotate it 90 degrees counterclockwise). In order to do a successful mod, you`ll need to familiarize yourself with this particular area of the circuit board, since we`ll be cutting a couple of traces and soldering several wires to it. Zoom in on the picture by clicking on it, compare it with your disk drive and make sure you can recognize the basic structures like the two parallel columns of solder points (which by the way is the Drive Controller IC). There`s no room for error! You`ll need to cut two circuit board traces that link the original disk writing stage with the write head assembly. This will disable the original, crippled disk writing circuitry and allow our custom circuitry to take control. Cut the marked traces in the exact same place that is detailed on the picture. If you cut them at another place you`ll also disconnect the pull-up resistors from the head assembly, which will prevent...
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.....
