...designing a little case to go around the stick.

I was working on something similar while I wait for my stick to arrive, can't wait!

Maybe a custom USB hub with enough distance between ports to allow for the height of the optical transmitter... Maybe there is some crypto-mining hubs from when USB stick miners was a thing that has some extra clearance...

Once I get mine I’ll try and design a low profile case for 3D printing, it would be difficult to design a case that works for both types of fiber optic transmitters though. It would be cool to make it look like any other usb stick!

Awesome ideas :)
I have started working on a small case which would allow them to fit side by side back when I started the project, but never finished it.

The width of the stick should be small enough to fit side by side on most usb hubs, so a case that gets glued on from the top and bottom would solve the issue, but that would then mean gluing something on which I usually try to avoid.
I haven't really looked into printing clips like those used in cheap enclosures, but since they seem to be maybe a few mm wide, they might still fit.
But the biggest issue I guess will be keeping the pins, and aux connector accessible.

Looking forward to more ideas :D

Just another small update:

I have gotten some of the old openmoko usb pids, so the thing is now properly usb compatible (though I think I have to pay fees if I actually want to be allowed to put the logo on).
Apart from that I have also been continuously working on bugfixes with VMS, but don't really get to release anything because I have found another bug to fix by the time I have drafted the release text :P

There are now also more circ parameters that can be used for circular modulation curves (no low pass on that yet though) and the drum map is taking shape; the effects of non-acoustic percussion instruments, that can be modeled with white noise are pretty much perfect and the drums are starting to sound decent as well with the help of multiple voices per effect. Bummer that I can only test my coil in my basement right now :P

Hello all!

I just received my midi stick in the mail and wanted to give it a quick test. I have it all setup and the blue signal light lights up for each note played but I am not getting any output on the transmitter LED. I tested the E96E transmitter before hand and it worked fine. I also removed the HFBR Resistor as I thought this might have been the problem. Any bell would be much appreciated, from what I can tell so far this is a amazing little stick!

Did you follow the quick start guide and create&select the configuration for your coil?
Without that it won't do anything to prevent damaging the coil it is connected to :D

I have it set to the default setting for the coil (100us max on time, 10% duty cycle, 30us note hold off) and LED3 which I have set to output on blinks blue with notes but still no output on the transmitter. For E96E types the LED Connects to the middle top pins right?
