Hey Electrical Engineers. I have noticed that the power coming off my bench power supply is really dirty. Where can I go to learn how to design a circuit to filter it and help clean it up?

@opsnlops And this pops up just as I'm going to bed. Lmao. Figures.

If this is still unsolved on Wednesday, please give me a shout.

(My first thought is a "bench power supply" ought to produce very clean power. If it doesn't, the power supply is faulty. But we have to determine what you mean by bench power supply. ;-)

Good night. :-)

@opsnlops So where did we end up on this? Did you track down the problem?

@shuttersparks I think so. I also have some ceramic caps coming in tomorrow so I can start learning about bypass caps!

@opsnlops Yup. .01 uF ceramics everywhere. Lol. Very important. With digital stuff, power supply rails with "blidgets and prangs" on them (as I call them) will ruin your day. Back in the early days of DRAM, this was the number one problem to look out for.

@shuttersparks Also tonight I'm in happy fun software land, so I'm in my comfort zone 😅
