Hi My encoders have arrived and im now ready to hook them up with the DIN module. Im not entirely sure whats what on these encoders. Compared to the specifications on smashTVs website: http://www.avishowtech.com/mbhp/images/encspecs18.gif of A, B and C on the encoder, which is D0, D1 and VS on the din. Thanks Carsten

Uploading all parts needed for designing Core, Ain, Din, SID (needs renaming). Zip folder contains 1. adobe illustrator file. Note that the bridges and component pins can be stredged without affecting the circles in the end. This is because they have been made as brushes. If it looks funny, maybe its because you dont have the brushes i´ve made. I dont know. Please report back! /carsten parts.zip

Thats me. I dont know how to make an image link. Do you? [EDIT]: fixed it. but its still ugly :)

hmmm. I can see the DINx4, try again. Updated dinx1and dinx4 with upright resistors For some reason the larger images cannot be opened completely in the first post. I have to click the image and say reload. Maybe its just the Opera browser [EDIT]: works in firefox AINx4:

Check out the new DINx1 AND DINx4. Is this a good and easily viewable layout? Feedback please Also, could someone upload an image of Dinx1, where the 100nF caps have been placed. Because i have my doubts about this. Carsten

;D

thats neat. I think i will use those for myself in the future. But i would like to make this collection as close to TKs quickviews as possible. /carsten

Im afraid i dont understand what you are writing. Are you describing a 1-pin resistor? Could you possibly show me a picture? hmmm. maybe up to several megabytes. But, i didnt know eagle could do stripboards. Maybe this will solve the problem of to few components. Pay_c: do you have your old designs laying around on your computer. Anyone standard modules? Please post them here. thanks /carsten

Made 2 updated versions of DINx1 and DINx4. I am planning to put them in the first post. But only when someone with a greater experience than i have, has said that it should work... or i have build it, and seen it working. But that wont be untill i am making a scan matrix. Maybe tomorrow i will make the DOUT, if i have the time. /carsten [EDIT]: I redecided. I am putting the none tested stripboards in the first post anyway, because pretty soon this thread will be in 2 or more pages, and will be really confusing.

Thanks :D Btw, some of these modules i am planning to do in something like illustrator/photoshop/gimp or something equal. How can i upload these - rather large - files. Or whats the best, and most durable, way of hosting them on a "third party" website? (hmmm, do you understand it?) /carsten

UPDATED 28. oct DINx4: Phew, thats a lot of wires and cuts. Same remarks as for DINx1. Use this for DINx2 and x3.

Thanks. Yep thats where i got DIY layout creator from. The dinx1 is made in that program. Unfortunately its very basic, has very few components and no possibility to import components. I would like another program. But for the Din and dout modules it will do fine. I think that the resulting image from diy layout creator is pretty nice and easy to overview. The demo should have a timelimit for saving. so that it takes 15 minutes to save. Unfortunatly it takes 60000 minutes - thats a bit more time than i have /carsten

UPDATED 28. oct DINX1: (not tested, only theory ;D) This new version is very close to the quickview (of dinx2), so i think it works, and it has gotten less wires. The board has not got the 100nF capacitors, you should put them on yourself. This was custom made in Illustrator /Carsten

Found a core in the forum: http://www.angelfire.com/electronic2/etko/photos/index.album?i=0&s=1 /carsten

This first board is damn ugly, but i want to post it because i have seen other beginners who had troubles with the documentation of the c64 psu circuit. And my layout might help to understand whats going on. Together with the layout in the bottom of my older thread: http://www.midibox.org/forum/index.php?topic=7631.30 And Altitudes quickview of a PCB: http://www.midibox.org/forum/index.php?action=dlattach;topic=7626.0;attach=348;image My board does not contain power switches, and the LED part. But that part can be easily intergrated since the 220 resistor is in place. I have made the drawing from my own working psu. Notice that the 7809 has the middle pin in the third row. Instead of using a row to go from the + of the bridge rectifier to 7809, i have just used an isolated wire. I will probably create a much more efficiant layout once i have my mbsid completely up and running. /carsten

collection of stripboard designs. UPDATED 01.11.06 Updated the optimized psu layout. Anyone who has got one laying around on there computer, please post them here! ======================================================== Components: Adobe Illustrator file, containing components. Includes components for core, din, ain, and sid modules.

Just a small remark: You dont have to push the PIC all down into the socket, as long as all pins connect. It will make it easier to uninstall from the socket, if you just place it lightly - atleast as long as you´re troubleshooting. I really hope you will have some succes soon, im glad its not me havent your problems. /carsten

First of i have to intergrate rotary encoders in my mbsid, they havent arrived yet, so there will probably be a few weeks till im ready to make the keyboard part. So if you think you will have the documentation in the wiki within a few weeks, you shouldnt bother to mail me. Otherwise i would very much like to see your project. Thanks for the tip. I also think i wont go with 37 keys, after i have seen the Korg MicroX which has only 25 keys like your project, and it seems like plenty. /carsten PS: have you hooked a scan matrix to the DIN, and do you have velocity control?

Interesting points. I have some further questions. 1. Isnt wavetables possible with the SID, or is it only some kind off semi-feature? 2. Does the SID break in live situations? 3. With continues edit of a sample, wouldnt granular synthesis be possible. I was actually only kidding about this in my first remark. I would guess it would use to much RAM.? I have a remark too. "Cheater" asks about the difference between the NES and SNES chips. Well, one advantage for the SNES (atleast where i live) is that it is far easier to get hold off, and far cheaper in the fleemarkets than the NES. Other than that, i dont know anything about the difference in the technology. /carsten

;DI´ll start by atleast trying to figure it out myself. I thought you had made one yourself. I think the matrix will do polyphoni just fine, according to: http://www.dribin.org/dave/keyboard/html/ Anyway. that solution sounds very simple. 37 keys would be just what i want. /Carsten

Hey Stryd. Thanks for the .zip But keep in mind that i havent even finished the SID yet. So could you please explain what it is. How can i use it. Just in short, thanks :) I build a matrix, and then i upload one of these files together with fx. the basic application file (sorry, i cant find it now, but you know what i mean. You upload MIOS, then this app to make it all running). Or, should i implement what you have sent me in the whatever i upload into MIOS. Thanks Carsten

I guess the above links would provide info enough to create the same as the c64 input, with a toy keyboard. Question: Will my midi input on the CORE be confused if a make a midi input comming from DIN? /carsten

Thanks. Didnt know the speakjet was in the wiki, never heard about the project till now.

Though i got my hands full with the MidiBox SID, i would still like to here the sound clips. I cant find it on youtube and the links are dead. Can anyone post them here or somewhere ells. Thanks /Carsten

What would you gain from using the NES chip instead of the SID? If you use midiNES or program the NES yourself, you only have 2 osc, 1 sample and 1 noise channel. Same goes for the C64 (which, as far as i know, only offers 3 channels). But when the SID is freed from its 4 bit restrain of the c64, it can sounds like something completely else. Dont, get me wrong, this is a question, not a shoot down: If you do the same with the NES chip. what have you gained, will it sound different from the SID, considering that it basically can do the same? /carsten PS: it would be really cool if you could use the sample part of the NES and create granular synthesis. ::)
