This looks cool, but I’m a bit concerned about the positioning of that bottom jack.
Different rail profiles have different thicknesses and leave slightly different amounts of space between the rails. I’m sure that I saw the specification of this somewhere but I can’t find it, now.
I’d just stick to the PCB dimensions that you find on commercial products to be safe.
The PCB is 110mm tall which seems to be the maximum that most manufacturers adhere to. Hopefully its fine but may just need to shift the mounting holes on the front panel up a bit on the next revision.
Just for reference, LZX frontpanels are 128.5mm tall. Rear PCB assemblies are always centered to that height and are 4370 mils tall (~111mm tall) and ((200 * HP) - 20) mils wide (so that would be 780 mils or ~19.81 mm for 4HP.)
Cool design. But as a minor quibble: monostable is an adjective and not a noun.
In the electronics world, it’s not uncommon to casually use it as a noun, in place of “monostable circuit” or “monostable multivibrator”. I’ve definitely seen it before.
I think you are technically correct, but I’ve definitely heard it used as both a noun and an adjective, I was certainly taught with it used as both. I wonder if there’s a British English / American English difference in general use?
did anything came out of this project?
it looks very interesting , a cool addition to the Castle range and possibly a starting point for DIY / bigger projects!
it would be nice if you have a updated / corrected schematic, so people could build it themselves
Hey thanks for the bump! Had a busy year so video projects got sidelined.
Coincidentally I actually picked this back up this week, I breadboarded a new version which was working well, I’ll finish the PCB and get it ordered soon!
Prototype PCB went out for order this week and hoping to receive it (and a few other prototype boards) next week.
There’s some ergonomics to review as I’m squeezing 4 jacks, 2 switches and 2 knobs onto 4hp but I’m optimistic it will be okay!
