I built my own Lo-fi Arduino Guitar Pedal. I`m even using a similar enclosure work tossed out a couple of thinwire->twisted pair converters that I snapped up. I think the only major deviation is that mine only has one output at present- I could add a second later, though. I got to thinking last week that a digital delay wo

uld be an interesting idea I had no notion that this would compete with anything in the quality department- a very short, crunchy delay I just wanted to try it out. So I wrote a little program and originally used an array of 512 values, and cycled through them, while recording point i, and playing point (i+1) (with edge checks and things like that, of course) It turned out that 512 shorts of storage must have overflowed available program memory and caused general non-functionality. Changed the delay to 256 shorts. That at least got me up and running. And it gave me about a second of delay time kind of unexpected (that makes the sample rate, what, a few hundred Hertz ). It also doesn`t give a very accurate representation of the input. A test went something like this: snare (pause) krrrzzk. I`ve done plenty of quickie hand-scribbled schematics, and at some point some computer-assisted ones (hell, I have a degree in Computer Engineering, it came up once or twice ). So I decided for the Arduino sequencer, I should do a little schematic using recent tools. EAGLE now runs reasonably on OS X, and for noncommercial/evaluation things, the light version is free. I`ve represented the Arduino connections and various jacks (MIDI, 1/4 ³ for clock, etc. ) with the pinheader objects which don`t 100% correspond to the Arduino pin numbers. Note that for example, Arduino pin A0 is actually pin 1 of the ANALOG block here. Hopefully that`s not...
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.....
