Very clear, thank you Sorin

I built a VCO today for my modular synthesizer. A voltage controlled oscillator. It gives three soundwaves, triangle, sawtooth and squarewave/pulse. And the squarewave has a input and a pot for voltage-controlled PWM 😊.

Very interesting. Great! Thx Sorin&Diana! 😚😚

Hello🤝very nice 👍👍👍👍👏👏👏👋👋👋

Diana: "Okay"... (She has no idea....)

Maybe it would be fun for her to build a oscilloscope-kit so she can look at her signals. I use a scope for my synths i built from a kit that i bought for maybe 25$, it works fine. DSO138 is it called.

Just an FYI that

I don't think you explained enough detail about how changing the current on the base increases/decreases the duty cycle. Is it biasing the transistor?

Merci mais les led sont inversé. Cathode + anode-.

HAHA! First "like" is mine!

noo its not touching anything 😁😁
