So I've been messing with something (maybe of interest to triaxis users)

[Tony]

Got sick of hacking up other pcbs that are not quite what I wanted. So I did this.




Struggled getting it down to a single layer but got there in the end.

Still a bit of tidying up to do here and there and I'm wanting to add relay switching to the main board but that depends on what a friend says about programming the microcontroller.

Going to etch a test board this weekend hopefully then if it works ill be ordering 25 or so depending on cost. Already got a fair few fully built units claimed but can happily sell the extra boards.

but like, for the guys that can't just look at a board and know whats going on here....


what do?

Figured the frequency bands would give it away.

5 band graphic eq set to the same frequencies (some are nowhere near what the label says) & bandwidth as the mk series one

Mark ii/iii/iv/v graphic eq in a box, but relay switchable 👍

[desertdweller]

Sounds great, would love to see you produce it.

[Überschall]

I’m down for a board if you produce them.

cool!

Awesome! I already have a 5 band eq pedal in the loop of mine, but I have to vouch for how much better it is than the dynamic voice.

Noticed a few errors in the previous layout that would've required some grade A bodges to get functional so I took the opportunity to shrink the size down a bit and also make it more DIY friendly. Can knock one of these out in less than half hour (quicker once i figure out a better way of cutting!)

Added some additional ground points around the outer edge to make using shielded cable easier & to reduce the number of additional ground wires needed.

Still not fully decided on the relay switching as that's going to have to be a small additional board due to this already pretty much only just fitting in a 1590b width wise. That and it's cheaper to just buy the stompville mini switch board than it is to buy the relay + parts etc individually.

Wow, I'm impressed you got that onto a single layer. I've never challenged myself to do that.

There's a single jumper above the icl7660s.

The old layout had 3 jumpers.

It was certainly a challenge. Having the ground trace go all around the outer edge helped.

It's been a while since I was really into designing pcbs. A few years. I really want to get back into it. It was so much fun, and it's amazing seeing it go from a schematic to a working product.
