jerash Posted February 28, 2003 Report Share Posted February 28, 2003 hey :Djust wondered what minimal setup can make the LCD work ?is power>core>LCD enough ? - MB64 firmware is in the chip - when i plug power, LCD baclight lits - then nothing elsei'm thinking about contrast ans luminance pots, but here's the problem : the mini-pots i mounted on the PCB are hidden behind other components, so i'm unable to turn them in another position...too bad, i'll have to remove them and put big solid ones :(RAF Quote Link to comment Share on other sites More sharing options...
TK. Posted March 2, 2003 Report Share Posted March 2, 2003 Hi RAF,yes, it must be the contrast pot. Your minimal setup will work. You could also try the LCD checker under Concepts->MBHP->Test programs...Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
jerash Posted March 3, 2003 Author Report Share Posted March 3, 2003 hi thorsten, thanks for the reply :)I mounted the JDM inside the box next to the Core, can i leave the inside connector in place to program the chip and then to test it, or do i need to put back the jumpers to test the burned code ?RAFpictures of the box :http://perso.club-internet.fr/raphael.mouneyres/Chamie/ Quote Link to comment Share on other sites More sharing options...
TK. Posted March 3, 2003 Report Share Posted March 3, 2003 Wow, you made a very clean design, I'm impressed! :)Especially about the nice show effect with the Plexiglas panel (you *must* integrate a blue neonlight into the case! ;-))Yes, jumpers are required, otherwise the PIC supply lines, the reset and D6/D7 are not connected with the rest of the core module.Best Regards, Thorsten.

rogic Posted March 3, 2003 Report Share Posted March 3, 2003 Hi and cheers to RAF!I have the *SAME* idea of laying out interface elements (pots, faders & buttons) on the Plexiglas (in my case some other plastic material, dunno name in english). My idea is to lay down all elements on this surface and metal case should go above. This way no screws will be visible on the top - faders also because they will be mounted on the plastic surface.Another idea: because I'm making mbox for Djing with Traktor, I am not sure where to put all buttons. So my idea is to make a precise matrix (2cm distance) of holes on the plastic and mount buttons on small veroboards with screw slots in a way they can fit to these holes (either horizontally or vertically). This way I can change positions easily.I think this idea leads to VERY modular midibox design :) Quote Link to comment Share on other sites More sharing options...
jerash Posted March 4, 2003 Author Report Share Posted March 4, 2003 (you *must* integrate a blue neonlight into the case! ) Hey , great tip 8) Thanks ThorstenI'm just wondering if i wont make a new case all in PLexiglass !I'm happy to know we have the same vision here ;pin fact this plexiglass surface is just a first try to connect everything and validate good working of the system ;D (so the 01 number upper right) Now i'll make a second surface withe small "modules" of plexiglass (3x12cm) that i can dispose on the surface as i wich (a kind of legos with pots, faders and buttons arrangements on the top) wich is the modular concept.By the way, i used Microsoft Publisher to lay down the layout and printed it with an ikjet printer. With the transparency of the Plexiglass i could easily use a permanant marker and draw the holes.peace, RAF Quote Link to comment Share on other sites More sharing options...
jerash Posted March 4, 2003 Author Report Share Posted March 4, 2003 just updated the web page with an 3D animation showing the modular concept :http://perso.club-internet.fr/raphael.mouneyres/Chamie/any comments welcome.. Quote Link to comment Share on other sites More sharing options...
