Altitude, I have recently started to put together the pieces for a seqv4. I know i have missed the boat in a way. however i keep running into your posts and i have to say they are great! the pcbs you are designing are very useful and beautiful. It seems you are a few steps ahead of me in this process and i was wondering if you would share your pcb designs with me? this is my third midibox project. the first 2 were based on the pic18f core. I have been building a modular eurorack for almost a year now and i am very excited about sequencing it without a computer. I don't want to come off like a leech. I wish that i could contribute more but it seems like you know what you are doing. :smile: Which core are you using? My stm32f pcbs just arrived from smash TV. I bought have a couple of original aout pcbs from mikes midi shop which use the MAX25. i dont think that i need a level shifter for my eurorack but it would be nce to have 11 volt gates for other analog gear (hence your awesome all in one solution). Have you acquired a pcb for the control panel (wilba)? I am waiting patiently for them to appear on smash TV. This should probably be a private message...oh well Again, great work! Cheers, K-rAd

Which core are you working with? I've started a stm32f. my first 2 MB builds are based on the original pic18f core.

Also very nice! Very clean designs. You seem to really know your stuff and you are working hard. I am waiting for a wilba pcb to be produced so that i can continue forward with my seq v4 and i keep running into your posts containing exactly what i'm looking for. It seems we are on the same path and you are about a year ahead of me any chance you will share your pcb designs? Thank you.

I have been using Kicad to design boards so i dont have eagle. maybe the gerber files would be usefull. sorry for questioning the design. i was just trying to help. :) Any chance for an oshpark share. i have some boards up there too.

Awesome Altitude! Thanks for clearing that up.

Also there may be a problem with this transformer. The min input voltage fora 7812 or 7912 is usually a few volts more than 12v. Voltage regulators like the 7812 usually call for 14v min input. So i would imagine that the transformer should be slightly larger 14v or even 18v per side. I'm using a 36v center tapped transformer for my modular and it works nicely. Have you tested this supply with a load?

looks nice man. maybe you could just make the board shared and searchable on oshpark? then we could order it.

julianf - I would love to buy a front panel from you. That red one is a beauty! Any color will do though. Please let me know how i can order one. Nice work!

Ok I'll be patient. Thanks for the response.

Thanks for the add. :smile: Let me know when it's time to pay.

I am building a SEQV4. This will be my third MB project. Very interested in being added to the Batch3 list! Please add me. I cannot edit the wiki. K-rAd Christopher Grabowski Chicago, USA
