Re: Soma - LYRA-8 DIY Kit
Ladies and Gentlemen.... I have begun my teardown of a factory Lyra-8. Surprise, motherfucker! It's not really the same as the DIY kits. Control and IO boards are V 3.3, and main board is V 3.4 Much of it seems to be for simplifying production...the switches and pots are NOT mounted to the backplane...

Re: 4U / LW format questions (possible new modules)
My solution has been to provide encrypted, watermarked schematics to those people that request them. I do it in such a way that a leaked schematic can be traced to a given individual. So far, no leaks! Because people who do clandestine stuff like stealing schematics of circuits that are not advertis...

Re: Soma - LYRA-8 DIY Kit
Yep. There are pads marked for power and headphone jack. I'm still stuck north of the border, but I decided (since I have a lot of time while waiting for things to happen) to buy a factory Lyra-8, and it arrived today. I'm going to pull it apart and see what the differences are between factory units...

Re: Lyra-8 DIY expansion and panels
You're not wrong, if you are working from Vlad's original "tweaks" document.
The mods I made were based off a board the same as you are building. I'm pretty sure I covered that in the build guide, but if you don't see it, send me an edit!

OMW! You're right. I never noticed that they were 90 deg PCB mount, as I used them on a 5u panel, so the mounting direction was immaterial. A quick look through my Alpha, Taiwan Alpha, MEC, B-E, and Daier catalogs shows no standard part numbers for a vertical concentric pot. I know you coukd have th...

Watch out, though... it's a slippery slope from these synths to contact microphones and the wild n' wacky world of acoustic droning. :foul: Tru dat!

Re: Soma - LYRA-8 DIY Kit
CONTACT pads. Any bare metal will work...even a bolt!
The DIN 653 screws are getting scarce. Try computer mod shops, as they often stock thumbscrews in M3.
I have some standard panels on the way that eliminate the DIN screws in favor of gold circuit touchpads.

Re: Lyra-8 DIY expansion and panels
Yes. Where a resistor or cap would be "tweaked," those leads go to a switch or potentiometer on the wings. There are switches on the wings that use the original values, so you can still play a "stock" Lyra-8 DIY. On the voice switches, there are electrolytic caps, so make sure you have the grounded ...

Re: Experience with cheap panel manufacturer in china?
Instead of searching for a panel manufacturer, i suggest working with a company that does enclosures and extrusions. They offer all of the processes needed (anodize, machine etch, laser etch, drag etch, silkscreen, direct print, finish, inlay) and are usually happy to work on flat panels. Setup cost...

Re: Kikad pcb layout to front panel
You can "plot" a layer to dxf. Results vary. If you have a way of converting a gerber to dxf, KiCad saves the drill locations in the .drl file, gerber format. I have had some luck using fusion to import the drl and export to any one of a number of other formats, but again, results vary. KiCad is pre...

Interesting! That sounds very similar to what I was working on before I had to shelve the project to work on some music commissions. I wouldn't think that an indicator for the gate would add a lot of complexity but I was trying to implement the idea with either optocouplers or buffers to keep the s...

Re: Lyra-8 DIY expansion and panels
Not positive, but there are basically 4 quad opamps on board...3 TL074 and one TDA2822. There are some summed voices there, and I think they go to the pins marked FMxx, and then to mixdry1 and mixdry2. Then it goes through the filter circuit, and then to final out. The mixing balance seems to be at ...

Re: Vias on pads at JLC assembly
I just spoke to my JLC rep.

In other news, they agreed to fold and fix a set of pc...

Re: Great table lamps - give me your ideas!
I like Ikea Jansjo lamps. I rip the bases off and drill a shallow hole to set them in, so it's just a hard mounted gooseneck.
Super durable, go where they are told, not too bright, warm light, and cheap as nails.
Don't use the USB ones...the bending of the lights destroys PCB connections.

Re: Vias on pads at JLC assembly
Yes, but it works anyway. I would not do it normally, just because I like to see where the vias are. But there is no reason not to on a modular synth, as long as you aren't assembling with a relatively small-ball solder paste. If you're using hard solder, it should be fine. Having said that, if JLC ...

Re: revisiting noise/drone machines
DIY drones are fun to build, and far easier on the pocketbook than tweaking existing synths past their resale value. I think my favorite genre is self-resonating philtres, followed by granular samples turned to audio rate. Over the years, I have found that too many knobs to turn is less inspiring th...
