ilmenator Posted December 3, 2008 Report Share Posted December 3, 2008 Hi all,I mentioned it elsewhere: I needed a GM5 that does not have all the MIDI connectors next to each other, because that just eats away too much valuable space for me. Also, I wanted status LEDs for each input and output - I find this quite handy for troubleshooting, and during the last ten years my old Thru box (which has a MIDI indicator LED) was the one tool I would take with me all the time - just because of the LEDs.Attached you can find some pictures of what I have come up with. All the easy-to-lay tracks have been done on grid-style board, with the more challenging connections done using a wire-wrap pen. The LEDs are low-current ones (and yes, one is still missing... have to order some more). The original GM5 board sits piggyback on this one and can be removed easily. The whole thing is USB-powered and has a 5m USB cable fixed to the chassis.The MIDI connectors have solder lugs, such that any mechanical stress on the PCB is avoided. They just snap into a rectangular hole in the chassis. The five inputs and outputs sit on separate and different headers to make servicing easy and confusion impossible. ilmenator_GM5_01.JPGilmenator_GM5_02.JPGilmenator_GM5_03.JPGilmenator_GM5_04.JPGilmenator_GM5_01.JPGilmenator_GM5_02.JPGilmenator_GM5_03.JPGilmenator_GM5_04.JPG Quote Link to comment Share on other sites More sharing options...
ilmenator Posted December 3, 2008 Author Report Share Posted December 3, 2008 One more picture and the schematic as attachments in this post.In the schematic, K1 connects to the GM5 board.Best regards, ilmenatorilmenator_GM5_05.JPGilmenator_GM5.pdfilmenator_GM5_05.JPGilmenator_GM5.pdf Quote Link to comment Share on other sites More sharing options...

Sasha Posted December 4, 2008 Report Share Posted December 4, 2008 Nice casing. What is it? Did you machined that openings for sockets or you did it by hand? It looks is it is cut accurately.I see you was short on green LEDs so you used black one instead. Interesting. :) Quote Link to comment Share on other sites More sharing options...

Sasha Posted December 4, 2008 Report Share Posted December 4, 2008 More Midiports than you'll ever need :) I don`t agree with this one. 5 ports is not THAT much if you don`t wanna chain MIDI devices. Quote Link to comment Share on other sites More sharing options...
sphere42 Posted December 4, 2008 Report Share Posted December 4, 2008 I'm sorry, I'm new to this whole Midi hardware stuff. I've always been working with midi notes inside DAW (Ableton to be specific) so posibilities of chaining devices together via midi is kind a new to me.

ilmenator Posted December 4, 2008 Author Report Share Posted December 4, 2008 Nice casing. What is it? Did you machined that openings for sockets or you did it by hand? It looks is it is cut accurately.I see you was short on green LEDs so you used black one instead. Interesting. :)The case is from Reichelt, very cheap (9,80 EUR) but designed very well: it has like rails on the sides so a 100mm wide board slides in nicely.The LED holes were drilled by hand using a Dremel (well, a handheld Proxxon Minimot). The rectangular openings were done drilling holes in the corners and using a jigsaw. This is rather unprecise, but the MIDI sockets nicely cover that.And for the LEDs... well, I guess you are right - haven't thought of actually making that a feature 8).The unit (or its twin) is probably going to sit in the back of a rack, which means that when I move the rack, I only have to unplug the USB connector instead of many MIDI cables.Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...
nILS Posted December 4, 2008 Report Share Posted December 4, 2008 Nice work illy!Out of curiosity - what did you use to buffer the signal for the LEDs?Conrad has really nice cases like those, too. Euro-card sized with removable front/top/bottom aluminium panels: http://www1.conrad.de/scripts/wgate/zcop_b2c/?~template=pcat_product_details_document&object_guid=91BC783B8D15EA56E10000000A010221&master_guid=&master_typ=&no_brotkrumennavi=&ownrow=19&p_load_area=0203051&p_artikelbilder_mode=Ein&p_sortopt=object_description&page=1&p_catalog_max_results=20&cachedetail=# Quote Link to comment Share on other sites More sharing options...
ilmenator Posted December 4, 2008 Author Report Share Posted December 4, 2008 Out of curiosity - what did you use to buffer the signal for the LEDs?74HC04 - the complete schematic is attached to my second post. You may want to change the values of R16-R20 and R21-R25 accordingly if you use different (=standard 20mA) LED types.Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...

Sasha Posted December 4, 2008 Report Share Posted December 4, 2008 That is very nice scheibenenteiser. Been looking for it for a looong time. I`m gonna order it right now. Thanks SLP ;) Quote Link to comment Share on other sites More sharing options...
ilmenator Posted December 4, 2008 Author Report Share Posted December 4, 2008 That's just perfect for de-icing a frozen MIDIbox! :DCome to think of it: does it work on a frozen Windows too? It should, as it is Scheibenenteiser... :D :D Quote Link to comment Share on other sites More sharing options...
