  4. MB-SID Matrix mit normalen LED´s

    in Deutsch

    Posted

    Anders herum habe ich mal gerechnet: 8x8=64 LED x 20mA = 1280mA Gut, mit einem 78S05 sollte das kein Problem sein. Ganze schöne Sromfresser die SID Synths *g

    Aber bisher habe ich auch nichts im Netz gefunden, wie man den Output verstärken könnte. Jeder Ausgang muss folglich 160mA max. (bei 20mA LED´s die es ja hauptsächlich sind) ab können.

    Falsch, es sind nicht immer alle LEDs an. Mit den Transis werden quasi die Reihen geschaltet oder so ähnlich. Die Reihen/Spalten sind aber nicht nur am Dout sondern auch an Din angeschlossen. Die LEDs gehen so schnell an und aus das du das gar nicht mitbekommst. ...  glaub ich mal ;)

    habe auch noch das stichwort "invertierte matrix" im kopf

  7. µDRIVE-uSD-G1, SD storage for MB???

    in Design Concepts

    Posted

    wohaa, i came around this ;)

    http://www.4dsystems.com.au/prod.php?id=15

    µVGA-PICASO-MD1 (available at sparkfun)

    I could imagine lots of boxes with a tft display ;) But that would be a lot of programming I think.

    Edit: After looking into the usermanual it seems that its "relativly easy" to send the basic commands for text and basic shapes, which are needed at first.

    wohaa

    but that SD is also great. Both have a serial interface. That works with the MB platform.

  10. Need dimensions of original C64 mainboard, Rev. A

    in MIDIbox SID

    As I already told "I can be totally wrong". Now I think/know I am wrong ^^. There are not much people out there which can handle all such things when they come here. But as a computer science student you'll surely have some knowledge already ;) Most people here aren't heavy electronics.

    I really didn't ever want to get in any offence against you. Even I am very happy, that people join the forum who perhaps could help US midiboxers instead of the other way because of their knowledge. ;) I hope you know what I mean. And pleeeeeaassssee share that layout with the community here when you have it ready.

    Why I wrote that about selling boxes:

    We had a little $%§!§"! here which used somebodys layout for his midiboxes and is selling them on ebay. Somebody saw that layout offered on ebay in a working mb sid. So it COULD (!!) be, that anybody wants to to the same, just that he uses selfmade pcb's which cant be directly seen as a midibox. But when I think about it, it wouldn't be a good idea to ask here for any dimensions ^^.

    nils: Nobody is allowed to sell midiboxes without tk's permission. It's not like offering several pcb's in our forums fleamarket.

  11. Need dimensions of original C64 mainboard, Rev. A

    First of all ... hi to the forum.

    I don't understand why you don't wait until wilbas 6582 is in smashs stock. you would only have to glue some pcb holders to the chassis. Then i see you are new here.... are you so familiar with pcb's that you can make such a big layout ?

    Why do you think it's better for you ? I don't suppose anybody who is not VERY familiar with electronics, pcbs and all the stuff can make such a big project running perfectly at once.

    Just if you hadnt read it! ITS NOT ALLOWED TO SELL MIDIBOXES !!!

    I just say this because I dont know any reason why you want to start in that way. Why dont you take the ready pcbs you can get? In a C64case nobody will see whats inside. But when lots of people should see this "one big" pcb for selling it, ..... see above.

    Surely i can be totally wrong, but I really wonder why you start like this.

  14. Verständnissfrage SID

    in Deutsch

    Posted

    Hiho Pascal und herzlich Willkommen ;)

    Wilba bitte nicht anschreiben, da dieser zur Zeit schon damit beschäftigt ist sein platinenlayout durch smash vertreiben zu lassen. Suche mal im Forum, da gibt ne Menge Lesestoff (und Bilder ;) ). Sobald es soweit ist wirst du das im Forum garantiert mitbekommen. Ansonsten kannst du dir ja mal für den Anfang was kleines bauen zum warmwerden ;)

    greetz

    PS: Preis für die platinen wird etwa 20$+ betragen. Also jeweils für main und control.

  15. x0xb0x rare parts

    in Miscellaneous

    Posted

    b-funk:

    I would take every part you have in the needed quantity to build my x0xb0x.

    What costs this set ? Could you make more such sets for others ? How much of these ? How can we pay you ?

    Who would be in with TheProfs offer ? I think its on the time to get the lists ready sooner or earlier.

    thaaaaaaank you for your support

  16. is the forum broke?

    in Miscellaneous

    Posted

    I have another issue, but perhaps its my laptop.

    I usually do autologin to the forum. but when i enter the mainpage i am not logged in. i have to click on a subforum to "activate" my account. now i can go to main again and i am logged in.

    Thank you Twin-x for your great support !

  17. Changing forum nickname

    in Miscellaneous

    Posted

    I have too agree Sasha, minor changes which can easily be seen, like his or mine (at least now ;) ) should be ok and recognizable by all who are affected by this person. Avatars are good to.

    If somebody is in a bulk order or has to be in contact with other people here, he should inform those about a changed nick you cant see directly.

    hmmm. thats what i think about it

    Hast du noch transparente ? Wär ja der Hammer, brauch nämlich auch noch welche. Wenn ja wie viele? bräuchte 32.

    Würde auch die roten nehmen falls von den transparenten nich genug da sind, von den roten aber schon.

  24. 1 button to rotate between bank sticks?

    in MIDIbox SID

    Posted

    I agree

    ....

    If the up button is pressed check if the number equals [numberOfBanksticks]. If so set it to 0 else add 1 to it.

    .....

    means: When you are in the last bank the "next bank" will be the same (=same number), because its the last bank already. If this happens ... goto bank 0. It's like a circle

    Hope that helped.
