I want to build Colpitts Oscillator Op-amp Circuit from here https://www.electronics-tutorials.ws/oscillator/colpitts.html
In the schematic it uses classic Op-amp 741 with 2 voltage sources. I have only Op-amp LM358 which using single voltage source.
What changes i need to do to schematic to...
I am stuck with this project here. I was trying to make a voltage controlled current source which can generate 1A with 5V. I used a digaram of 741. But it didn't work. Is there anyone who can help me with showing me a circuit that can work? Thanks.
I have been posted this idea in another group,http://www.eevblog.com/forum/projects/a-hearing-aid-amplifier/ ;)
Many of them suggested many idea, but let me start it again for particular design,
It looks clear, I have been trying
1. Treble and Bass control by frequency...
