I've been using .3mm and .5mm for signal and power respectively. Not a million miles away. I don't see any reason to go smaller unless it solves a specific layout problem. I'll sometimes run a super fat ground trace but it's probably overkill

I got fed up with the data viewer in LT Spice so I vibe coded this one page web app alternative You export your data from LT Spice using the cartesian default format and drag it onto the page to show it. It will superimpose multiple files on the chart area and you can hide/unhide individual...

Mid control sweep looks like a genuine improvement I've been putting volume controls before tone stacks lately, it's good to see I'm not completely mad Does the LDO really give 9V out from 9V in? That is a low dropout. The datasheet says it'll take 16V max, easy to fry on a dark stage after a...

Yeah if you want that wee-wooo wee-wooo spaceship thing that's the way to go

Well it's only fair that they compete on a level playing field

The LED seems less gooey and squidgy than the incandescent in the electrovibe I built. But that could be a host of other things. This one feels less obviously Jimi Hendrix if that makes sense. But still a great circuit, one of my faves

Tayda have them mate in different colours. Window dressing innit

My hack was making numbered pot functions in lt spice that map to the pins on my diptrace component. Essentially idiot proofing pot orientation. Another was making pot and switch components with just the pins and the component outline on the bottom assembly layer. The origin point for the...

It's alright as long as you don't eat the pigment. Fatal error (literally)

@jackhuggins85 did you pop the 8.2V zener in position Z1? That should clamp the bucket chip supply (VC) at 8.2V

Oh crikey glad I read this. I've got one waiting to be boxed up now So 'cool audio' literally means 1V cooler. Cool (y)

A decent solder sucker will change your life. Couldn't live without mine. I got the engineer branded one 5 or so years now 9/10 it works first time. For the other 1/10 when a bit of solder stays stuck in there you can heat the pad and feed a safety pin through from the other side. Once you...

Finally got around to boxing this up, Abyss uni-vibe vibes You can't get them in shops any more due to EU cadmium diktat. Such a shame Oh well, we make one The word 'throb' is too loaded in my mind (especially in reference to a knob), so I went with 'weight'. It sounds snappy with 'rate'...

Turns out LTSpice uses the same namespace for functions and components, meaning C1, C2 and C3 are literally the worst function names possible. So I've prefixed the functions with the letter 'p' because I'm a prat Third time lucky: .param x = 1e-7 .func rlog(a) { 1 - (1-a)**3.3 } .func alog(a)...

Just found those pot models on github ta, will check them out I feel locked into LTSpice now. A sunken cost fallacy. Or Stockholm syndrome There was a different bug in that second code block relating to the limit logic nesting, so I've gone back to the first version rather than try to fix it...
