Below that is the clock section. The knob controls the internal oscillator`s speed, and that can be voltage-controlled via the `Speed In` input. Or, you can insert your own clock signal via the `Clock In`. This is slightly unusual, but I think having the option is useful. -Then you get to the 10 steps. Each has a CV control (+9V to 0V), LED step i

ndicator, and individual CV and Gate outputs. You`ll also note the three-way switch. This can turn on or off each step, or can set that step to reset the sequence (so you can literally have a 1-step sequence if you want, or you can switch the 9th step to reset and have a musically normal 8-step sequencer) -After that you have Hold and Reset inputs. Hold will holda step indefinitely given a high gate signal. Reset will reset the sequence to step 1. Either can be controlled with anything that can create a high gate signal, even a +9V CV signal. Each also has an attenuated input, should you need it. -Master CV and Gate are just like the individual CV and Gate, but each step outputs to it. This way you can, say, patch the master CV to an oscillator and sequence the pitch. You may ask why I did what I did here, and it`s mainly for maximum patchability. It`s totally possible you`d never use parts of it, but I`m sure you can see the usefulness of each part (assuming you know how most sequencers work nowadays) This schematic isn`t entirely accurate, mainly because my version of LTSpice doesn`t have some of the parts. Given the description you can build it, though. You`ll have to pay attention to your exact 4017 and its outputs, otherwise this schematic will be a bit wonky for you. Oh, and of course, you`ll want to connect your 3-way switch`s 3rd setting to your reset pin if you want that. You could also just patch a step`s gate...
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.....
