Noise Floor (No-knob HM-2)

[benny_profane]

While Brian was introducing the Boss Bonanza, I suggested a one-knob HM-2 as a potential giveaway. I thought the knob should be for the LEVEL; Brian said that the HIGH control was vital to dialing in the 'ICE PICK.' We both realized that how cluttered that one-knob interface would be. There was only one option: a no-knob HM-2 with internal trims. Betty Wont provided the name with the following comment:

From what I understand, the HM-2 is the standard by which all other pedals are measured. So anything with the HM-2 circuit would be....wait for it.....boss.....

It is the boss of unacceptable noise floors, for sure.

To accompany this most user-friendly panel arrangement, the board layout is super streamlined: optimized with overlapping resistors and a top half that looks like celebratory confetti—a reaction we've all had when playing or hearing an HM-2.

I haven't boxed this one up yet (partially because the board itself is so amazing), but it is verified. And, maybe surprisingly, the noise floor is not too out of control.

10/10 best board of all time. Thank you, Brian, for this masterpiece.

Nice. I was thinking about laying out an HM-3.

I need this in my life

Glorious!

I think you should add one knob that controls the LED brightness and label it Darkness

Love it.  What's the comment on the board about "duct tape"? 

To be honest, a whole "No knobs" range of pedals would be awesome.  I'd stop dicking around with the knobs and maybe learn to play guitar.

I love how this board offends my OCD.... Oh It hurts so good! Thank you sir may I have another!

This was a lot of fun—I really hope this makes it to the shop as a regular project. Happy to see a positive reaction to this!

That's brilliant. I may have do that when boxing it up!

The silk at the top says: "Use 1/8W resistors and monolithic caps only! or duct tape" [Note: I did not follow instructions]
The silk indicates that C12 (1u5) "must be wired off-board" — I sorta did that with a 1u and .47u in parallel.

Absolutely agree with a 'no knobs' range.

Isn't that upside-down 4558 just wacky? The haphazard component arrangement really did slow down my assembly time significantly.

This is amazing.

This is rad, I'm loving the layout. It looks like my daughter's room after we're done playing with Lego

I know someone is going all OCD psycho mental on this and it makes me happy.
