  1. MIDIbox 64 questions

    in MIDIbox HUIs

    Posted · Edited by SLP

    Hey ANdrw,

    You asked something about potentiometers/encoders. I think i want potentiometers. They are able to send MIDI data, right? I dont know what encoders are... could you please explain?

    everything you connect to your midibox will send midi data. buttons, encoders, pots/faders.

    You could even connect a methane detector to it, so that it will send midi data when someone in the room farts.

    pots/encoders:

  2. Ponoko - Kreditkarte

    in Deutsch

    Posted

    Hallo,

    Ich bin gerade im Begriff, mir bei Ponoko eine Frontplatte für meine Nixie-Uhr machen zu lassen.

    Nun musste ich leider feststellen, dass es die Ponoko-Leute immer noch nicht auf die Reihe bekommen haben, endlich mal Paypal zu implementieren.

    Ich bin nämlich leider nicht im Besitz einer Kreditkarte (hab noch nie eine gebraucht).

    Jetzt habe ich also folgende Bitte:

    Könnte vielleicht jemand, der im Besitz einer Kreditkarte und eines Ponoko-Accounts ist, die angehängte Ponoko-svg-Grafik für mich fertigen lassen und bezahlen*?

    *Die Kosten belaufen sich auf ~25$ (~20€, P1, 3mm schwarzes Plexiglas, inkl. Versand innerhalb Dtl.) und werden selbstverständlich über PayPal bzw. Banküberweisung beglichen.

    Wäre super, wenn mir jemand den Gefallen tun könnte.

    Gruß,

    Matthias

    p.s. ich musste die datei zippen. anscheinend akzeptiert der uploader keine svg dateien...

  3. Faders for MidiBox 64

    in MIDIbox HUIs

    Posted

    @SLP: What did you pay for the Mono-Faders?

    IIRC, it was somewhere between 1 and 2€. But they were the cheapest ones I could find, and they feel terrible.

    If I were you, I'd accept Roger's offer and buy him a beer (or two) ;)

  4. Faders for MidiBox 64

    in MIDIbox HUIs

    Posted

    Hi Stefan,

    the faders will work, but they are stereo faders. This means, that they're basically two faders in one housing with one common knob.

    I did a quick search, but I wasn't able to find some mono faders at reichelt. This is weird, because I've bought some cheap "radiohm" faders (10k, mono) some months ago.

    Try searching Conrad or eBay.

  8. Few questions about midibox plus 8

    in Parts Questions

    Posted

    I was building a MBplus 16 3 years ago. It's cheap and simple.

    And you want a display. at least during the act of building for troubleshooting.

    You can remove it afterwards.

    Question 1. If midimerger turned off by default - how to turn it on without a display? (Type two times "left", once "menu" or something)

    Don't be silly. leave it on or leave it off. - or use a display

    Question 2. If configuration is sent into controller - how to make sure that it is saved there and not have to send again at the next power on?

    No idea. it should work if everything's set up properly.

  13. Are these LEDs suitable for the sammichSID?

    in MIDIbox SID

    Posted

    alright, let's have a look at the specs:

    Forward Voltage : 4.0V

    Forward Current : 20mA

    the sammichSID design feeds the LEDs with 5V. That is one Volt too much.

    Kirchhoff's circuit laws (google/wikipedia that) say that the current flowing through the resistor is as high as the current flowing through the LED (IF=20mA)

    R=U/I

    R=1V/20mA

    R= 1V/0.02A

    R=(1/0.02)Ω

    R=50Ω

    So 50Ω should be the minimum resistance you should put in series with the LED. You can experiment with some different values to reach the light intensity you want.

    You can always go above 50Ω, but you should never go below. Decreasing the resistor value will increase the current which will in turn heat up the LED and kill it.

    edit by nILS: Nope, that's wrong. Try again. Also note the 220Ohm resistors on the CS PCB.

  14. Sammich SID

    in MIDIbox SID

    Posted · Edited by SLP

    So can i program anything through midi on the Sammich?..like using a BCR-2000 or something and assign knobs to parameters and such or is that too advanced for this little fellow?..just fun to know..and if not..without such a thing how do i program it?..cant find a manual anywhere on the nets to help explain how much i can do with the little one..would be fun reading until i get further on the waiting-list.^^

    welcome aboard, Ender!

    the CC implementation chart can be found here:

    I forgot to mention the SID V2 Editor:

    Using the editor, you can use your PC to control your SID, save patches, etc.

  16. Will someone build me a midi controller?

    in Design Concepts

    Posted

    calm down please.

    Midibox is a non-profit, DIY-community.

    This means, that it's forbidden to sell complete midiboxes (and make a profit with that).

    If you find someone who will build you a midibox "for free", that's fine then.

    TK has put a LOT of work into this project and he shares it with us.

    It's neither right nor allowed to make profit that way.

    If you don't want to get into midiboxing, you can just go out and buy some commercial midi-controller.

    Midiboxing is a lot of work, but in the end you've got your own midi-controller that is designed by you and that fits all your needs.

    And I think that's worth it.

  21. Stereo SID wie anschließen?

    in Deutsch

    Posted

    Was hat der grüne Draht J14 für eine Bedeutung nur so interessehalber.

    J14 war eigentlich als "Strobe"-Leitung gedacht. damit ist es möglich, einfache metallflächen als taster zu benutzen. wie genau das funktioniert, weiß ich nicht. Wahrscheinlich wird die platte mit einem kurzen stromimpuls geladen, und dann über deinen finger entladen.... also so in der art.

    In deinem Fall wird J14 irgendeine "enable" leitung steuern. Damit kann der Core eben mit einer Datenleitung den SID-modulen sagen, wer von den beiden jetzt gemeint ist.

    weil ich sowieso nur 2 SIDs rumliegen habe :tongue:

    schonmal den "sammichSID" angeschaut?

    gibts komplett als Bausätze mit Gehäuse und Platinen.

    Ich weiß jetzt nicht genau, welchen J1 du meinst.

    es gibt auf der Core-Platine einen Stromversorgungseingang, an den du praktisch alles über ~7V anschließen kannst. Das wird dann eh erst gleichgerichtet, runtergeregelt und stabilisiert.

    die SID-Module haben einen eigenen Stromanschluss für 9 oder 12V.Das ist abhängig von den SID-chips, die du verwendest.

  23. Magnetic Encoders

    in Tips & Tricks

    Posted

    the mainly question is where to get the magnet for that...

    and whats the priceing for that....5$ are a bit to much for peace of silicium :o , if this would be cheaper then a mechanical encoder  ;) - i would start to thinking of cnc designes for axis, shafts and so on... but with 5$ i dont start to think about that...

  24. Advice On starting midibox sid V2.0

    in MIDIbox SID

    Posted

    Welcome aboard Guido!

    I don't have experience in building pcbs or other electronic apparel but i know how to soldier and use a tester... I want to bild a Midibox with 8 sids and 4 cores do you think i will be able to handle the construction even without a lot of experience? and where do you suggest me to buy parts ?

    check this out: http://www.midibox.org/dokuwiki/wilba_mb_6582

    I will need lot of help during this operation but i hope to make it..

    If there are any problems, just read through ucapps, the wiki and the forum (search!). If your problems aren't solved afterwards, just ask your questions in the chat.

    regards
