Altitude

I dont know about the Rogan stuff, they look OK (and the mold quality is not that great, lots of flash, not nearly as clean as I would expect at the price) but how they attach is an absolute nightmare with that metal bushing. I am not even remotely comfortable with the amount of force it takes to get those on and even less comfortable with the prospect of trying to get them off. I've blown apart encoders trying to get Albs parts off and the Rogan stuff is 10x worse. I still vote Sifam for small diameter parts. The textured finish is great and having the end cap removable/replaceable makes it really easy to go from pointer-less to pointer and keep the same look for under a buck each. $4.77 a knob @ 500 pcs is for crazy people who believe the knob will make it sound better. Intellijel use Sifam knobs if you need an example What is the status of this bulk? I looked at the wiki and there are two people signed up

let me guess, you are using inkscape?

OSHpark PCBs have plated through holes, no need to solder on both sides.

what's layer 20? Those sort of errors shouldn't matter. What does the ERC say? I'd also get the DRC file from Lain, it will go beyond the stock DRC. Also: put your meter between +5 and GND, +12 and ground, -12 and ground an make sure you dont have continuity. I dont know the details of what the short circuit protection there is on the DAC but if there isnt any, a short on either of the 12V rails would cause that failure so poke around those traces

Hmm. Have you run the ERC and DRC for OSHpark on that? That isolation looks really tight and recipe for shorts. Also, I cant tell if this is an artifact from the screen capture or a short..

You could always use the Mutable Instruments SMR filter out of the ambika, great sounding LPF and you get a VCA as well

That's why I prefer the CEM part

sounds like you wired them incorrectly

The SIL header can go on either side, it's up to you really. I'm going for max flexibility here. I ordered some protos and those have pin 1 marked on the silk screen

fin!

out of curiosity, why the long length and the 90 deg angle?

One thing I have learned to loath building these projects is wiring up LCDs, It sucks and I hate doing it. A few years back I saw an adapter for going from a 16 pin SIL header to a 16 pin IDC connector but have not seen anything like that since and never bookmarked the link. Solution: DIY. these are $1.75 each at OSH park http://misw.us/sil2dil.zip

Yes. You can remove the 5V regulator in this case (i'd leave the caps)

I'll post the files once I have finished mine and checked everything out. There are some differences in assembly and parts (9mm standoffs instead of 10mm since the front panel is 2.5mm thick). It still was an expensive case ($225) but when you figure the panel and back from front panel express will run you ~$150 plus the pactec case and shipping will be another $50, it doesnt really end up being that much more.

I just got some 2mm and 3mm scratch resistant ones laser cut, shoot me a PM

That's not right, 0.5A current draw and the heat usually points to a short somewhere..

..

So I've been meaning to do this for a while but the costs were pretty ridiculous at front panel express but I now use CAM expert where the prices are much more reasonable, This is the type 2 profile, you lose some real estate on the back panel so the D connector and mix out have been removed

Paul, Might want to read through this: http://www.midibox.org/dokuwiki/doku.php?id=encoders&s There are different settings for different encoder types in MIOS

there are some debounce settings in the firmware that you can mess with

Jameco has them in stock (and cheaper) https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=2184333 And they will ship US Mail internationally

^ Disagree 100%, an "old school" linear supply will be 10x bigger, 5x more expensive, and will get much hotter than a modern decent switching one which will also be 5x more efficient, just search the forums and see how many people here are using Meanwell PSUs without any issues. There is a reason that no one uses big linear supplies any more. For a $40 Meanwell you get a 5A 5V rail with +/-12V. How much would just a linear transformer cost to do 5A? Buchla Music Easels use SMPS for a reason.

I guess it's a matter of taste, I have mine sitting almost flush with front panel (12mm spacer IIRC, but check that) using the stock x0xb0x style caps. I like how that looks and they work fine.

Electro and ceramic caps help. An on/off switch is the most useful imho.
