SSl Blog Post 02 Hello again, Last time I wrote about the design process of my console. In this post I want to focus on the electronic part. In the last couple of weeks I searched for the right knobs, faders and pots for the project and I nearly found all I need. The pots were the simplest part. I opted for the Alpha 10k Lin https://www.musikding.de/Alpha-Potentiometer-16mm-10k-lin Each channel will have one motorized fader. Here I choose the PSM01-082A-103B2. https://www.mouser.de/ProductDetail/bourns/psm01-082a-103b2/?qs=MAZTpT1IVl8rvdecO07rRA==&countrycode=DE&currencycode=EUR 14,76€ when I buy more than 25 is a good deal I think. The ones from alps are very pretty, but with prices over 30€ per piece they are quite expensive especially because I need 33. For the bus channels I opted for simple 60mm faders. Also 10k lin, not very investing. https://www.reichelt.de/schiebepotentiometer-stereo-10-kohm-linear-rs60n12-lin10k-p73870.html?&trstct=pol_1&nbc=1 The knobs where a little harder to find. For the Solo Cut and Rec knobs I want to have knobs with Leds which I can connect to an DOUT module separately. So I could press Solo on the console but deactivate it inside my DAW and the LED would follow my actions. After quite a bit of searching and some phone calls with distributors I finally found these. https://de.farnell.com/nidec-copal-electronics/cfpb-1cc-4w9/drucktaster-spst-0-005a-5vdc-panel/dp/3498758 The knobs inside the channel strip are still to be found. The need to be snapaction knobs with a white cap with the measurements of 5mm per side. I couldn’t finde the right ones even after quite some hours of searching. Maybe I’m just searching without the right search terms? Maybe someone of you knows the answer to that problem I didn’t start the search for LEDs just yet. I think and hope these should be easy to find. For the modules I chose STM32F4 for the cores, AINSER 64 for the pots and faders, NG MF for the motorfaders, DIN for the knobs and DOUT for the LEDs. I especially need quite a lot of AINSER modules and I’m still figuring out a way to connect more than two to an STM32F4. I found some blogposts but could get the answer out of these. They suggested it should be even possible to connect more than three? I obviously want to use as less cores as possible. This build will be huge either way. I can connect the MF modules directly to a pc without a pc. Thats what is written on the website. But how do I connect these to the pc? Via midi? There is no USB port on these modules right? And I also should cascade them. I need 5 modules. I want to use 33 motorized faders and that’s quite unfortunate because every mf module only supports 8. How do I cascade these modules? Also via MIDI? The last problem I ran into is the meter bridge. This could be a whole blogpost of its own… My plan was, or partly still is to use 10 7“ displays connected to a 10 times HDMI splitter, which tells the PC there is only one REALLY big screen. But after buying quite some displays to test out I figured out 90% of the screens for sale online are totally crap! Ok, I searched for quite cheep ones, but I need 10 of them and if I had unlimited money I would buy the original ORIGIN console… But I don’t have access to unlimited amounts of cash so I need a cheap display which works. The first one I ordered was the perfect size and easy to operate. But I only could see the image looking from one specific angle. Moving my head just a little bit the whole display would turn blue. The second one was advertised to be 7“, but the one that were delivered to my was only 3,5“…are you kidding me? Out of anger I searched for analog VU meters. I really like the looks of these and figured out these work with voltage. Is it possible to drive VU meters with a midibox module? Maybe with an AOUT module? So many more questions but I already wrote a whole book here…sorry for that. If you still reading in this point thank you very much! Have a nice day! Frederik

Hi, I need help. I want to make a lighting midi controller. I need 15 motorized faders and 60 backlit buttons. I looked at many systems on how I could make this. I came across Midi Box and I like it so far. But I don't know what I'm doing. What Parts do I need to control 15 motorized faders and 60 buttons using this system and how would I connect it all. Thanks in advance

Wie bekomme ich es hin, dass das MF Modul mit dem LPC kommuniziert? Also z.B. Wenn Fader eins über 50% dann schalte eine LED ein und sende die aktuelle Faderstellung (hier 64). Danke für eure Hilfe
