yay
FWIW - even with the acrylic it’s pretty tough to get it all super-flat on that side (with regular wire).
I am also having some issues with it multitriggering columns when pressed hard/at an angle. Probably a hardware issue, something too tight or crooked alignment of pads?
thicker top panel seems to help. (for me)
how many 3mm grid layers are over the buttons? If you add one more you might see the press errors go away.
2x3mm top panels at the moment. 3 might not give the button enough clearing… Tricky. Does it help because it “stabilizes” the button presses?
Stabilizing… I think so?
3 layers gives you just enough clearance, but 1mm shorter feels better to me, to that’s why I have a 5mm spacer in there on mine instead of 2x3mm.
Also make sure your button rubber parts are properly lined up on the pcbs - there’s alignment nubs for that which could cause the buttons to be less in contact if the wrong way around.
Still an issue with multitriggs after adding another layer. This has to be due to too much preasure being applied to the buttons, right? The pads seems to be aligned perfectly. Might just help to do some sanding/filing of the grid layers. The laser cutter used had a wonky laser tube. So the cutting is alot less precise than on the Fates case.
noob question… @okyeron im thinking of making a diy pcb that holds both the adafruit usb breakout and the teensy.
I assume i can load firmware to the teensy from the adafruit usb port? Or do both ports need to be exposed?
Also i need to cut the teensy external power pad right?
Cheers
Wait one moment. You have well aligned the pads on the pcb boards. There are holes in the pcb where the pads fit nicely. Without the extra layer all is fine here. Also to much solder between the frontside of the pcbs raise the pads. On the back use something like resistor legs to avoid too much solder. Pictures?
No solder on the front. I used pins to solder the backs together(-INT since that is not used). pads align nicely and everything seems flush.
Well i soldered it all: front pads and all the 5 back pads. Maybe worth a try?
For the rest looks all good IMHO…
I think the issue is due to wonky laser cutting. I’ll do some sanding and try again.
This is where I am at. See my Instagram for some work in progress. I am going to try a couple options - a very thing (0.4mm) regular pcb and then a “flexi pcb”. I hope to have a new design variation worked up tonight.
With the usb breakout you don’t need to have the teensy usb exposed and no, you don’t need to cut the power trace. But - only use one of the usb jacks - not both (unless you’re doing something different like splitting power/data)
Does this happen reliably on the same neotrellis board each time or all over the place?
Could be a “bad” board (wonky diode or something)?
Fwiw - I’ve NOT soldered across the big pads on the led side of my boards
Hiya! @okyeron on i finished my build and is working good on my mac. What fix do i need to do to use it with fates? I cant seem to find the mentioned fix. Cheers!
I set up a shell script for this.
cd ~/fates git pull cd install/norns/scripts/ ./diy_device_fix.sh
Then restart norns (SYSTEM>RESET) or reboot.
(Usual disclaimers - this will void your warranty, etc. - you’ll need to do this again after updates)
Thanks for the help, unfortunately its not working.
I think i need to update my norns, but i was holding off since i had read there had been problems with the lates norns update.
So update and then re run the shell scrip?
Update probably doesn’t matter, but sure why not.
You will want to reboot with the grid disconnected. Then it may take a couple plug/unplugs to get the grid to recognize. Also - the grid takes about 4-5 seconds to “boot” so be patient.
Sanding helped the multitrigging issue. Seems to be working fine now.
@okyeron is there a reason why you have the rainbow boot commented out in the project? I really like the idea.
Couldn’t make it work properly. Something to do with the callbacks not initializing when the rainbow was there. Got frustrated and commented it out.
Corner led blinks on startup/init tho.
Ok so im in!
First of all thanks so much to @okyeron and everyone involved in making this possible!
I had been quite disappointed with my untz experience and not being able to get it working as a monome… but really glad i managed to reuse it by changing the pcbs and doing some mods.
I put the adafruit usb and the teensy on a pcb inside the case, and made the connections with wires.
