Hi, hopefully this is the right place to post this question. I’m looking to build an oscillator. I have all the parts ready to order and I wanted to double check that I’m not making an obvious mistake. I’m completely new to this and I thought it would be worth a second opinion to know if the...
Sincere apologies for any ignorance I'm about to display, I'm more an artist than an engineer. If I am building a synthesizer which has multiple relaxation transistor oscillators all going into one output, running off of 9v, how I would I look into combining a MIDI input so you could control...
Hi, I am making a module for a DIY modular synthesizer. The module applies an ADSR-envelope to an audio signal using a 10K MPC41010 digital potentiometer.
I suspect, I made an error in the circuit, since I now have 2 Nano's which will not power on from USB (pwr led flashes a few times and then...
Hi!
I would like some opinions please if you dont mind. I have one of those new, small analog synthesizers (Behringer Model D). It has a bunch of potentiometers, and switches, etc. to control the sound manually with hands/fingers. In my dream, I want to be able to control the sound...
I am a beginner and wish to tackle this project...
I have an old Yamaha breath controller device that has a 3.5mm Jack and requires -9v on the tip (the sleeve is positive). It draws a current of approx 7mA to 20mA depending on how hard you blow it (from what I have managed to research but may...
I have recently been attempting to delve into the world of electronics and have been trying to build a very basic oscillator using the CD40106 chip. I have set up the circuit as follows:
9v to pin 14
pin 7 to ground
1 microfarad capacitor from pin 1 to ground
100k ohm potentiometer between pin...
