An early stage of the homebrew AD9833 sig gen. Using an Arduino nano and an AD9833/MC41010 DDS/attenuator module. I plan to trickle out status reports in a non-linear manner....

Prior to actually drilling that case I prototyped the control part of of the generator, so there was at least a chance I'd end up with something working.

I wanted to use an optical encoder of this type for the main control as I have used them before for a VFO and they are really nice. A ball race at each end make the action super smooooth. No clicky knobs here!

@vk3kri but there affordable small encoders "without clicks" so called "no detent"?

@ly2ss Yes, I've seen them, or at least have used them, but the type I've used just feel so good.
If my current bench audio sig gen is any guide, I will spend a lot of time twirling the dial back and forwards, so I think I'll get my moneys worth.
