Designing a white, pink & blue noise generator from scratch

Support the channel... ... through Patreon: ... by buying my DIY kits: In this episode, we’re torturing an NPN transistor into creating some white noise – which we’ll then filter to also get some pink and blue noise. If you want to build along, here’s the bill of materials: 1x TL074 quad op amp 1x BC548 transistor 1x 1M resistor 6x 100k resistor 1x 51k resistor 1x 22k resistor 2x 10k resistor 1x 2k resistor 3x 1k resistor 1x 680Ω resistor 1x 1µF foil capacitor 1x 33nF foil capacitor 1x foil capacitor 3x 1nF capacitor 1x 330pF foil capacitor Chapters 00:00 Intro & what is noise? 03:00 Transistor breakdown & white noise 10:51 Shelf filters & pink noise 19:09 Limited high pass & blue noise
