I originally wanted to purchase a Nebulophone but, my El-Cheapo price range didn`t like the tag. I realized that I could program my own AtMega 328 by using ArduinoISP Then I found out that if the code was Arduino compatible, why not just use the Arduino as a Nebulophone Well it was kind of a waste of Arduino but at least I could simplify circuitr

y. I recently built my DoAnything Shield and could now have access to any pin I wanted. I looked at the schematic and realized that Dr. Bleep had left plenty of things missing such as where did the stylus go and, where were the keypads and so I emailed him and after a long string of emails everything was cleared up. 1 SPST/SPDT slide switch (Any type of switch that can move from one position to another until pused again work (Toggle, Rocker, etc. ) It doesn`t matter whether it is SPST or SPDT the second connection is nothing. ) 1 LED and Photocell assembly (I got mine from here but I didn`t realize that the same website had this which is much cheaper although untested. You could also make your own by bending an LED over to a photocell that can range from 10k to 200k. and then covering it with some black tubing. I`m not sure the one I had is exactly 10k to 200k but it worked. )
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.....
