sonicwarrior Posted June 15, 2008 Report Share Posted June 15, 2008 suital from the sequencer.de forum was so kind to create a single PCB for the MIDIbox CV project.The thread (in german) for this was:http://www.sequencer.de/synthesizer/viewtopic.php?t=18474More information in english can be found here:http://www.midibox.org/forum/index.php/topic,11656.0.htmlPlease ask questions about the PCB there.I'm taking over the bulk order of the PCB in bundle with the necessary MAX525BCPP+.One set includes 1 PCB and 2 MAX525BCPP+.As I have no PIC burner the necessary PIC is not included.Instead of the difficult-to-get MAX6007B you can use a LM385-2,5. You'll only need to re-calculate some resistor values.Costs per set: 35,20 Euro (old info)(Without shipping/package costs)The whole thing works only if I can sell exactly 50 sets! (Because of packaging units)If someone wants to take part in this buld order please let me know here how many sets you will take.Deadline is the 30.06.2008 at 20 o'clock (CEST).List (29.6.2008):sonicwarrior: 3 setsamp1ron: 3 setsDoug Wellington: 4 setsJaicen: 1 setMadox: 2 setsStormB: 1 setsnykehd: 2 setsxarolium: 3 setsLeft: 0 setsEdit: I'm located in Germany!Edit2: Here is the requested pic of the PCB (3D model):Edit3: Page (currently only in germany):http://www.sdiy.de/de/projects/midiboxcv.html Quote Link to comment Share on other sites More sharing options...
asafnetzer Posted June 15, 2008 Report Share Posted June 15, 2008 Hi sonicwarrior,Can you please give more info on this project, I guess people would be interested if they would know what to expect.Best regards,Asaf Quote Link to comment Share on other sites More sharing options...
ilmenator Posted June 15, 2008 Report Share Posted June 15, 2008 Yes, more info (jpg of layout or Target file) would be fine. I have some 525 - what about the PCB only?Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...
sonicwarrior Posted June 15, 2008 Author Report Share Posted June 15, 2008 It is basically CORE & AOUT on one PCB.I can post a picture maybe in two days (previously I won't have the time).what about the PCB only?No, because of the packaging units I mentioned.

Jaicen Posted June 16, 2008 Report Share Posted June 16, 2008 I'm in for one kit, saves me ordering everything seperately! Quote Link to comment Share on other sites More sharing options...
sonicwarrior Posted June 17, 2008 Author Report Share Posted June 17, 2008 I've added a picture.TK has made a suggestion to include the PIC in the kit (he would then burn the PICs and send them to me).I have to think about that because I don't have enough "IC sticks" (I hope this is the correct translation of "IC-Stangen").Anyway I think a Safeshield box (from Warmbier) would be best. Would only add ca. 0,6 Euro to the costs of each PIC butyou can re-use it at home or use it to store the PIC.Here is a picture of the safeshield boxes I mean:But I have to investigate deeper at home.

ilmenator Posted June 17, 2008 Report Share Posted June 17, 2008 Hi,I notice that you did not include the bipolar option into your board design. For the sake of a wider range of possible applications (eg think filters), it would be a good idea to include that.Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...
sonicwarrior Posted June 17, 2008 Author Report Share Posted June 17, 2008 It is not my board design:suital from the sequencer.de forum was so kind to create a single PCB for the MIDIbox CV project.As prototype PCBs already have been made any further change would require a new prototype PCB and someone who is willing and has the the time to re-design the PCB +new stuffing and testing of the prototype. And 32 new resistors and 8 new trimmers will have to be placed somewhere which means a bigger PCBwhich is more expensive + I have to charge the costs of the prototype PCB (prototypes are expensive).In my eyes an external solution or modification would therefore be better if you need negative CV values.Personally I currently won't need that and I would not be happy with a further delay of this project because I need theMIDIbox CV soon.

sonicwarrior Posted June 17, 2008 Author Report Share Posted June 17, 2008 I've made a new thread for discussion & information:http://www.midibox.org/forum/index.php/topic,11656.0.htmlNow I didn't had the time to investigate on the PICs. :(From now on please only post orders here.

sonicwarrior Posted June 20, 2008 Author Report Share Posted June 20, 2008 34 sets left and 10 days to go. Let's see if this groupbuy will happen. Quote Link to comment Share on other sites More sharing options...

madox Posted June 22, 2008 Report Share Posted June 22, 2008 34 sets left and 10 days to go. Let's see if this groupbuy will happen.Any chance the deadline can be extended? I would have thought more people would be interested in getting their hands on the Max525's. They're not so easy to find, if one doesn't have access to samples.

sonicwarrior Posted June 22, 2008 Author Report Share Posted June 22, 2008 Well there is no cheaper way to get a MIDIbox CV with AOUT anyway but maybe not so many people need a MIDIbox CV.I don't want want to run this as a never-ending story and I need a MIDIbox CV soon for myself so there is no way to extend the deadline.

madox Posted June 22, 2008 Report Share Posted June 22, 2008 Well there is no cheaper way to get a MIDIbox CV with AOUT...That was my impression. It's a great chip, great MIDIBox project. Come on people, sign on, sign on! A pro quality MIDI-CV box is something which just creates so many opportunities and options in a studio.

snykehd Posted June 24, 2008 Report Share Posted June 24, 2008 I'm very low on money, but this group buy is the cheapest way toget a midibox cv - and I need at least one :)Count me in for 2 ! Quote Link to comment Share on other sites More sharing options...

I just assumed that postage would be OK, at the appropriate price. Postage from Germany to Australia is not the cheapest, though I have had no difficulty with this before.I also have had little luck purchasing these in Aus. I did manage to wrangle a couple of samples, but the local distributer was really not too pleased that they were not linked to a bulk manufactured product.
