TK. Posted May 2, 2004 Report Share Posted May 2, 2004 Check out the creation of Doc! :)He wrote some interesting comments to his design, the english translation in bold font:Wie häufig im Forum erwähnt, habe ich (inspiriert von Axel) eine Midibox LC mit 16 Kanälen aufgebaut. Betrieben wird das Ganze unter Cubase, was mittlerweise mehr recht als schlecht auch funktioniert. Damit ich 16 Kanäle nutzen kann, habe ich die Assignement - Tasten, die Fader Channel & Bank tasten, sowie die Shift-Tasten mit Dioden verkoppelt, so das ein tastendruck stets beide Core Module bedient. In der Aux-Section sind aber die Taster der rechten 8 Kanäle noch mal ohne Diode auswählbar, damit ich mir immer schön die Kanäle 1-8 und 9-16 darstellen kann. Dies funktioniert zumeist recht passabel.Nun zu den Bildern:As mentioned earlier somewhere in the forum, I've build this 16 Channel midiboxLC (inspired by axel). The host application is Cubase. Because of the missing function in cubase to control an extended controller, I've chained the common switches of the two 8-channel sections (like Bank left/right, flip, shift, ...) with diodes together. Now I can control two LCs with one function button. In the AUX section there are all buttons for the right module seperately (without diodes). In this way I can make my desk ready for channel 1-8 on the left module and channel 9-16 on the right module. It's not perfect - just a workaround till further notice from Steinberg (Update).The pictures:zeigt das Mainboard des Mixers. Ich habe alle DINs und DOUTs auf extra Platinen gelayoutet, damit ich konsequent 20-polige Pfostensteckverbinder verwenden kann. Alle Verbindungen sind gesteckt, damit das Board oder einzelne Platinen zu Wartungszwecken entnommen werden können.shows the mainboard of the mixer. I've build a whole board for all DIN and a board for all DOUT modules so that I can consequenmtly use 20ch ribbon-connectors with ribbon cable. All connections of the mainboard have plugs. By doing this, I can unplug the whole mainboard or single boards for support reasons.zeigt die Gesamtansicht der verdrahteten Frontplatte. Ich habe mich diesmal dafür entschieden, sämtliche Bedienelemente (außer Motorfader) auf eigenen Platinen zu entwerfen. Die Kabel sind hier zwar gelötet, das Layout entspricht jedoch weitestgehend der Belegung auf meinen DINs und DOUTs, so das die Verkabelung rasch von der Hand geht.shows the total rear view of the wired frontpanel. This time I decided to build boards for all control elements except the motorfaders. At this end the wires are soldered, but the layout follows almost the connectors on the DIN an DOUT boards. This way the cabling is a bit easier ...zeigt eine Detailansicht der Encoderplatinen und der rec/mute/solo/select/vu-Meter - Platinen.shows a detail view of the encoder-board and the rec/mute/solo/select/vu-meter-board.zeigt eine Detailansicht weiterer Schalterplatinen, sowie die Jog-Wheel Platine und die LED Anzeige. Auf der Jog Wheel Platine ist außerdem noch ein ULN Treiber angebracht, der die 12V Birnchen für die Transportschalter antreibt (war ne Idee , die ich von Dir aus Deiner Relais-Steuerung entliehen habe...). shows a detail view of several "switch"-boards, the jogwheel-board and the MTC LED board. The jogwheel-board also hosts a special ULN driver for the 12V-lamps of the transport-buttons (this was an idea borrowed from Thorstens relais-option for the MIDIO128). You can use common switches then without soldering leds into them.zeigt eine Teilansicht des Mainboards mit den DOUTs und DINs für die rechte Seite. Hinten erkennt man auch das Netzteil und den Trafo. Beim Netzteil habe ich ein regelbares Dualnetzteil (mit 2xLM723, 5V, 12V) entwickelt, daß mit einem 2N3055 als Treiber (nicht auf dem Foto) mindestens satte 3A pro Spannung liefert. Die 12V verwende ich nur für die Transport Birnchen. Die Spannung für die Fader kommt aus einer eigenen Wicklung des Ringkerntrafos. Dieses etwas aufwendige Netzteil hat den Vorteil, dass es sehr genau abgeglichen werden kann und ausserdem die Spannungen stets konstant hält (auch wenn alle 16 Fader arbeiten.).shows a detail view of the mainboard with the DIN ond DOUT boards for the right half of the box. In the back you see the transformer an the power-supply. The power supply is a own cration. It's a regulated dual-power-supply controlled by two LM723 regulator ICs and powered by seperate 2N3055 transistors. The output is 3A per voltage (more than enough). You can adjust the voltages (5V and 12V) very exactly with this application. It's very stable, even when all 16 motorfaders are moved parallel. The 12V is only used for the transport-lamps. The power for the mf-modules is on a separate tapping current of winding on the toroidal core transformer.zeigt die beiden MF Platinen und das Netzteil.shows the two mf-boards and the power-supplyzeigt Detailansicht DINs und Douts linke Seite.shows a detail view of the left DIN and DOUT boardszeigt eine Totalansicht der Frontplatte. Die Platte kam übrigens von Schaefer. Der Aufdruck stammt von einer T-shirt Kopierfolie (aufgebügelt) und wurde anschliessend mit KFZ-Klarlack überzogen.shows the total view of the frontpanel. The frontpanel is from "Schaefer". The lettering was layoutet on the pc and the printed on a special transparency for an iron (german: T-shirt-Bügelfolie). After that it was coated with clear varnish (for cars).zeigt die rechte Seite der Frontplatte.shows the right half of the frontpanelzeigt die linke Seite der Frontplatte.shows the left half of the frontpanel Quote Link to comment Share on other sites More sharing options...

moebius Posted May 3, 2004 Report Share Posted May 3, 2004 That' s so pro, so pro, grrr.. working for Behringer?Sorry, liked original (2*40, as yours) "Axels" more, as a design (I'm on the blue phase, you know).Incredible!But did I see "new" (only) board layout for those LC buttons, maybe? MBHP? :)Bye, Moebius Quote Link to comment Share on other sites More sharing options...
doc Posted May 3, 2004 Report Share Posted May 3, 2004 Hi Moebius,You can be sure, I'm not working for Behringer...(I think the quality of TK's projekts are much better than B...) ;DI'm not quite sure what you mean with your last line.If you mean the printed boards on the back. Yes they are "new". If anybody is interested in the layouts: I'm gonna publish them the next days(weeks) for you.thanksDoc Quote Link to comment Share on other sites More sharing options...
pay_c Posted May 3, 2004 Report Share Posted May 3, 2004 Very very cool indeed! Muuuuch respect!!! :DAwesome work.Wasn´t it hellawork to layout all the PCBs again?I´m especially interested in the DIN/DOUT PCBs cauz´ u used those 20 pole ribbon-connectors. Are they compatible to all the other MIOS stuff? Will you publish them?Much respect again! Greetz! ;D Quote Link to comment Share on other sites More sharing options...
doc Posted May 3, 2004 Report Share Posted May 3, 2004 Hi pay_c,thank you.Yes it was hard to layout all this pcbs. But it was not so hard than cabling all this stuff on vectorboards.I'll publish all layouts in a few days (week). The problem is the format. I use a program called "SPRINT LAYOUT" for layouting the pcbs. I'll make pdf files of the layouts, so that everyone can use them as "idea". If anybody has sprint-layout, he can use the original files also, of course. But be warned: There are sometimes little errors in the layout I corrected on the boards but never on the layout. The DIN/DOUT Layouts are exactly those on the hardware pages. They are compatible.greetsDOC Quote Link to comment Share on other sites More sharing options...
MTE Posted February 17, 2008 Report Share Posted February 17, 2008 Wow last post 2004 :)Do you have some layout-files of the frontplate, or some better pictures ? I wanna see the scales in high resolution, cause they inspire me :)Really nice box you've made ! ! Quote Link to comment Share on other sites More sharing options...
doc Posted February 24, 2008 Report Share Posted February 24, 2008 Hey MTE,sorry for findung you're question so late ... Never thought somebody will find this old stuff again... ;DThe LC16 still is still alive. b.t.w.It's much bigger now (It's a LC40 now).I have the Schaeffer-File of the frontplate and a Corel-Draw file of the surface-printing.Write me your email Adress via PM and I'll send it to you.greetsDoc Quote Link to comment Share on other sites More sharing options...
MTE Posted February 24, 2008 Report Share Posted February 24, 2008 Done, thank you so much !! :D Quote Link to comment Share on other sites More sharing options...
seppoman Posted February 24, 2008 Report Share Posted February 24, 2008 LC40?? please upload some new pics :) :D Quote Link to comment Share on other sites More sharing options...
doc Posted February 24, 2008 Report Share Posted February 24, 2008 @seppomanSure. But this may take a little time. I moved to another town an all studio equipement (including the LC40) is safetly packed in cases & containers. When the new rooms are ready (I think in June) I'll make a photo session of it.I just made 8k "Expanders" (3 pieces), just like the Mackie ones with the same layout like the LC16, but without control section.greetsDoc Quote Link to comment Share on other sites More sharing options...
stryd_one Posted February 25, 2008 Report Share Posted February 25, 2008 I moved to another town an all studio equipement (including the LC40) is safetly packed in cases & containers. When the new rooms are ready (I think in June) I'll make a photo session of it.Ahh you're about to have to deal with this nightmare too... The pic doesn't capture it all, but that pile is as high as it is wide... They were neatly coiled when I put them in the box, honest!Worst thing is, there's another pile with the looms! ugh!help.JPG Quote Link to comment Share on other sites More sharing options...
doc Posted February 25, 2008 Report Share Posted February 25, 2008 Hey stryd_one,that comes close to the mess I live in at the moment. Someday, Someday ... everything is getting better!greetsDoc Quote Link to comment Share on other sites More sharing options...
Shorty Posted July 30, 2009 Report Share Posted July 30, 2009 Hey, Doc, I wanna see that 40, I am about to jump in to a 48 or 60Also, see my first post under Design Concepts, though it might get moved to HUIhttp://www.midibox.org/forum/index.php/topic,13843.0.htmlWhat are your worst limitations and workarounds?I'd like to know so I know what potential problems I'm facing.Thanx Quote Link to comment Share on other sites More sharing options...
