Correct.
Are there similar LEDs like these for through hole ? :hmm:

I'd still stick it behind a translucent acrylic panel, if you want a panel.

Yeah, I guess that would work.

:mrgreen: In all honesty, I'm not acquainted with the complete Mouser catalog! By through-hole I was implying a more typical through-hole setting, one that could utilize a panel. I presume these LEDs you're using cannot be mounted on the inside. You'd have to make a new panel and somehow mount these high enough to sit nicely on the inside of an aluminum panel. Feel free to correct me if I'm mistaken.

After owning a few BL modules as well as the LP1 from Soundmachines I'm fine with the PCB as panel concept, as long as safety has been considered.

actually there are. Sparkfun sells a led ring that can be soldered more easily: https://www.sparkfun.com/products/10595
Would also relieve the strain a bit if the panel is flexing (which could be a problem in this design).

And there is always the traditional way: use 16 through hole leds soldered individually. It's 48 3mm leds then, should be possible (but the look will be very different and i like the the design as it is).

that Sparkfun part won't work here, the LEDs used here are addressable RGB LEDs, like this one: https://www.sparkfun.com/products/11821
(note this shows WS2812, but I use the newer WS2812B)

these do exist as 5 and 8mm through hole as well, either as single LEDs

or as pre-wired "strings":

Image

so yes, a more traditional module with a front panel with 48 5mm holes for the LEDs is possible, with the LEDs soldered into the PCB instead of surface mounted ones. in that case somebody else has to make the panel, I would then only supply the PCBs to mount behind.

but that will have to wait a bit :)

I think it looks great.

As a variation on this idea, would it be possible to build a similar module where each LED was a pushbutton switch, activating the triggers, and the central dial could spin their position? Just rambling... ;)

proper panel as in? aluminum and through-hole LEDs?
That sounds like a relatively easy upgrade to the existing design?

I just skimmed through the thread again. The boards look great av500. Congrats. Was there a final set of prices? Kit vs. pcb vs. pre built?

I'm working on that. it's my first proper design, so bear with me please

Great fireworks.
We would like to buy a complete
and finished module, ready to send rhythms in space.
Add us to the list.
Thank you.

If so I'm definitely up for one

I'd like to be able to switch each of the 6 triggers on and off. Is anyone aware of a small module that I could use to do this?
all you need is a 2hp panel with 6 toggle switches or locking push buttons, then wire the 6 channels through these switches and back to the main board

something like this:

if you mount that on the left side, the switches won't interfere with the patch cables even.

How wide are the pulse outputs on this?

Asking because some possible destinations are fussy about pulse width. Eg, the pulses from Pamela's Workout in euclidean mode are too wide for it to be useable with a Nord Drum because it triggers on both rise and fall (pulses in standard mode are much shorter and work fine).

pulses are as wide as the incoming clock signal, they follow the original clock edges up to audio rates. I'll look into adding a setting that produces short pulses for any clock rate.

what would be a good pulse width to trigger drum machines?

Would it be possible to add something where the user can set the pulse width? Per channel even? I've run into the problem where different modules need different pulses (re-triggering, gating, etc), like the Blue Lantern bass drum seems to need really short triggers, but then playing samples on the Bastl grandPA they'll only play the width of the pulse in some modes.

This.

It was the same deal with Drum Dokta Mk1 which needed between 6 and 10 ms pulse width to give "standard" drum sounds.

It's hard to suggest an ideal pulse width as there is so much variation in what drum sound sources look for. As a general principle its probably simpler to extend a trigger if its too short than it is to shorten one that's too long so maybe something around 8 ms might be a good default.

If I get time I'll check what Pamela's Workout delivers in normal mode as thats seemed to work well with different kit here.

thanks. I'll go for 8-10ms for a start.

CD4538 could be used to give individual pulse width control
or you could just build 3 of yusynths pulse delays and have delay as well
as control over pulse width- probably a better option for most
It probably wont happen today but if it does it definitely wont go smoothly.

ok, I added a setting for a fixed pulse width per channel (channels 4,5,6 follow 1,2,3). the actual pulse width is a global setting same for all channels, 1ms or 10ms

if the incoming clock is faster than the pulse width it will override that and produce shorter pulses.
