    So getting real close to ordering everything.
    Im currently writing up a spreadsheet with a list of the LEDs required for the version of the front panel without the light pipes for the the LED rings.

    Sauraen just one thing I noticed about the FM widget,

    particularly the 4x BiColour Red/Green LEds for the operator nodes.

    I noticed you're not using light pipes for these in your video, and also they're not pushed through the front panel. It looks like theres a gap or a hole if you will.

    Is it possible to push these through the front panel?

    Edit: I see now you're using 2 single / separate Leds in yours, 1 green and 1 red with the anodes of each in common.

    I presume if I order the Mouser ones you linked I can easily push them through the front panel?

    How do I even use this?? I've downloaded it.....does it need to be compiled? Never ran a Java script this way. 

    It's not Java Script, it's a Java executable. 

    Just download and install Java on your machine and run the .jar file. 

    Make sure the midi in and midi out of the MIDIbox SID is connected properly otherwise you won't be able to open the patch editor interface.

    @Smithy, if you're thinking of a SEQ V4+ build, I'd hold off. Often the cheaper OLEDs are about 5mm taller, and I think we need that for the V4+. For colours, the best approach is to use a white one and put a plastic sheet (gel) in front of it.

    Do you know off hand what maximum height the oleds need to be?

     

    both the ones Peter and Johey linked are 9.3mm high.

    Totally forgot you suggested this at the meetup. Cheers!

    Right now I'm trying to figure out which LED colour scheme for the full LED Rings.

    Theres 4 options here, basically the encoders are turned all the way clockwise so all leds are illuminated.

    21014784_1277968158997465_544862855_o.pn

     

    The first option shown (ATK Rate) is how Sauraen has his configured, (except with Blue LEDS instead of green.)
    Technobreath prefers this option.
    I think the first and second from the left look good.

    The 3rd option has a yellow LED to indicate the midway point. 
    And the 4th is like how a dj mixer or mixing desk shows the volume on a channel, although looks a bit weird in a circle.

    Thoughts?

    Thanks a lot Sauraen!

    I didn't realise that you stacked the genesis modules on top of each other, I like the idea of using headers instead of cabling for the data lines and power lines.

    Actually it might be worth adding this information to the Wiki. I can do it if you like, and maybe embed the photo you sent.
    What length are the nylon spacers you used to stack the Genesis Modules?

    And also the male headers and female sockets for the headers?

    I see the 4th Module is using longer spacers but I presume you were just using up what you had to hand.

    @Sauraen - can you provide dimensions of the PCBs in the back mounted vertical? + how deep the CS PCB is from the back of the CS alu plate - basically the height of the standoffs + PCB - is it standard 1.6mm PCB? I'm fishing for if the PCB sandwitch (within the given dimensions) can be mounted horizontally.

    This is answered in the wiki me thinks:

    http://wiki.midibox.org/doku.php?id=mbqg_fp

     

    "The spacing between the underside of the front panel and the upper side of the PCB is about 0.27” (7 mm), which is originally defined by the encoders and the 3D printed buttons are made to match this. I used 1/4“ nylon spacers/standoffs from eBay plus a flat washer (4-40 or M3) to achieve this spacing. I used 0.75” 4-40 screws to put together the front panel, in which case the depth of the assembly was 0.75“ with the electrolytic capacitors and pin header / IDC connector sticking out past this. The panel and PCB can be fastened together with 4-40 or M3 screws. "

    Thanks a lot man!
    Technobreath has volunteered to design a wooden case.
    I wonder if its possible to get the dimensions of your own case when you get the time? Maybe the angle of the slope of the wedge shape also.
    And if its possible to make them even smaller if theres a lot of space.

    Looks like the missing parts of the puzzle are coming together with help of the community! :)

    For the power supply I'm thinking about going with this 5VDC 1.5A Switching Power supply.

    http://cpc.farnell.com/powerpax/ptd-05015b/ac-adaptor-5v-1-5a-regulated/dp/PW02343

    Would you recommend connecting 2 Voltage Regulators like the OKI-78SR-5 you suggested to it as well as the fuse holder?
    I want to keep it simple, so would just like it to run from a 5V power supply only.

    Also, I may be getting ahead of myself but where can I download the compiled firmware for MB Quad Genesis?

    I checked the MIOS SVN, especially trunk/apps/sytnhesizers, expecting it to be there.

    @Smithy: yes, you found a mistake. R14 is DNP. I updated the page, and also fixed another minor mistake I noticed.

    When you're talking about "enclosure for the Front Panel", do you mean an aluminum or plastic panel for the front panel PCB to mount under, or do you mean an enclosure for the synth?

    Sorry for the vagueness! I mean the enclosure for the synth!
    Do you by any chance know the model of the project boxes you found? I wonder if they can still be purchased as they're perfect!

    Edit: I see in your original MB FM video that its an electronics training kit. Id almost buy a kit just to use the enclosure!

    Hi Sauraen,
    I'm compiling my parts list on mouser and just wanted to confirm:

    Chip U3 - 74HC137 - 3-to-8 decoder with enable, for selecting board and sound chip

    Only one chip and one bypass capacitor is needed in total for a Quad Build right i.e. Genesis Module 1?
    Since I'll be using jumper wire to specify the number of the other 3 Genesis Module boards.

    Thanks.

    Its sad it came to this after 15 years of service and it won't be the same without you as the go to guy.

    But thanks for being such a huge contributor To MIDIbox over the years and for everything you've done for us.

    Wish you the best of luck in the future.

    What exactly is non-transparent here?

    Its not what is in this thread that is non-transparent, but the behind the scenes.
    I feel too strongly about MIDIbox and I think I'll just take a step back on this and let whatever happen and not get so invested anymore.
    People who don't know whats going on in the background won't understand it anyway so there's no point in discussing it further.
    I just think the whole mess that's been going on a few years now could have been handled better with more open communication.

    BTW, I'm all for alternative PCBs like lis0r's and Andy's to see the light of day. 
    All I want to see is people continuing to enjoy their MIDIboxes and be inspired and creative with them.

    Normally I would automatically defend MIDIbox and hiss at any mentions of board files going public.

    But honestly I can understand the frustrations of users on here.

    There has been a complete lack of transparency for a good while now. 

    Personally I think how its being handled is a mess, and could be handled a lot better considering the community is dying each week.

    TK to say that Smash wsa contacted by Lis0r with no reply and leave it at that is a bit unfair as you know there is a lot more going on behind the scenes. It just makes him look bad or ignorant.

    This lack of transparency has also lead to a lack of transparency on Smash's behalf also.

    I'm not going to go against your wishes and expand on any of this publicly, 

    I just think the community would benefit from knowing what the hell is going on since there has been a total lack of supply of boards, and its turning people away from MIDIbox.
