Harford Hackerspace wanted to make our own Tron Identity Disc using the Netduino, allowing us to quickly load different versions of code to change the disc`s functionality. David Powell, Gary W. Cygiel, Jeremy Ashinghurst, Paul King, Jason McMahon present a simple lightshow in this tutorial, developers can easily extend the code and hardware to p

roduce an interactive game. To get started, we purchased and retrofitted a Spin Master Tron Identity Disc replica, which kept us from having to create a new physical disk, and so sidestepped the most difficult aspect of the project. Placing the Tron Idenity Disc on or removing the Tron Identity Disc from a charging station will raise an event handler. Placing the disc on the charger will start a pulsating animation. Removing the disc will resume the previous animation. The original Deluxe Tron Identity Disc contained six LED on the outer ring, which left much to be desired. Our modified disc includes 30 LEDs on the outer ring and two LEDs illuminating the inner arc. To get started, we opened the disc by removing its four Phillips head screws. Next, we removed all electronics including the wires, tilt sensor, LEDs, switch, speaker, and microcontroller board, taking care to not lose the plastic momentary button, since we later used it to switch between our animations. Then, we used a Dremel with a cutoff wheel to remove any unnecessary plastic in order to make room our own electronics. See Figure 1. As shown in Figure 2, we used superglue to attach the narrow end of the momentary button to the plastic Tron ring. Then, using the Dremel, we cut a small L bracket from a scrap piece of acrylic and attached it with cyanoacrylate. We reinforced the L bracket using hot glue and applied a small amount of cyanoacrylate 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.....
