TheBlackBox: Release v2.0 - Propeller HSS FX/Sequencer with Digital Audio SPDIF output.

This is to announce v2.0.
Major changes, are use of a single eeprom and crystal.
Improved programming / commenting.
More videos of TWO black boxes operating together using the clock sync feature(new in 2.0)
-future input of accelerometer, theremin, and piano interface. Plus other input methods.
-uses VIEWPORT as a tool to do diagnostic and virtual interfacing.
-each prop communicates at 250Kbps using the "fullduplexserial" object.

Description: Propeller BlackBox Audio Sequencer V2.0
This device is an audio waveform creation and 32 step sequencer.
(for musicians, mostly electronica dj's) (aka... bassline sequencer, drum machine, 303, 909, etc.)
This device creates audio, it does NOT accept audio INPUT. (yet)

Features:
-Live fx mode to allow direct output of the current waveform set by 12 different potentiometers.
-The sequencer allows the fx to be loaded into any one of 32 steps in the sequencer.
- SPDIF audio output or analog output via a switch (not both at the same time)
- analog output to a monitor(at the same time as spdif/analog output above (headphones or studio speakers) to allow auditioning before outputting live.
- 3 encoders that allow - BPM, main volume, and BPM jumps(1/3, 1/2, 1/4, 3/4, 2/3) and a switch for jump direction. (main volume and bpm jump programming not complete yet)
- BlackBox to BlackBox CLOCK sync, input rca, output rca.(serial @ 150Kbps, works over 1 foot rca cable) (this is so many of these devices can be connected to one main BEAT CLOCK MASTER.)
- 32 LEDS are used as sequencer step indication, ALONG with using the 32 LEDS as buttons to load waveform
- 2 leds that start/stop the sequencer and live fx waveform.
- fully open source that uses the HSS code to generate the audio.

Schematic: See attachment BlackBoxV2.pdf

Block Diagram See attachment BBv2Block.pdf
- AudioSequencer(U1) prop uses all 8 cogs and has 18 I/O free.
- PotReader(U2) prop uses all 8 cogs and has 6 I/O free.
- LedReader16(U3) prop uses 5 cogs and has 8 I/O free.
- LeadReader32(U4) prop uses 5 cogs and has 4 I/O free.

    Watch the videos that are at the beginning of this thread.

    If you still don't get it, look up something called a drum machine, a synthesizer, and a sequencer.

    Clock Loop.. awesome its a good demonstration on how to use multiple props as well , very nice
    Thanks, Yea, my method of prop communications isn't the greatest, but it works.

    I basically just blast the values over the serial, and on the receiving prop I have it look for the start number "say 113" and then after it sees that number, it starts to capture all the data after it for a certain number of bytes. Its pretty simple and allows me to transmit at 115200 baud. Although I use 2 pins for the serial I/O, it could be done with a single pin. This is because I do not use 2 cogs to transmit and receive the data, I do the TX and RX sequentially.


    Overall this design could improve:
    (use a single eeprom, and clock all props from a single master prop.)
    Re-use the TX and RX lines between props as a way to upload the boot program from the master prop, plus do the serial communications on the same lines, after the boot program has been uploaded.

    I am sure the code could use major enhancements also...

    This first revision is the hard and dirty working v1.0

    This is the result of an EE who is out of work due to the financial terrorism that the federal reserve and federal government have chosen to inflict on the hard working class.
    I.E. my job canned me due to cut backs. (insult to injury, the state refused my unemployment claim over a technicality) (combine that with the housing market prices....which resulted in my foreclosure, etc...) Its a horrible time to have lost a job, and owned a house. Wheres my bailout?

    This post is to announce v2.0

    See first post in this thread.

    The file attached is the viewport output.

    Nothing special yet.

    I don't understand viewport very well yet.
    But I hope I can include a virtual interface to the black box using viewport.

    The image attached is the second box that was also made by freehand wiring.
    This would have been done with a pcb if funds were not limited.

    Awesome project!

    I'm even more impressed by your use of solid core twisted pair to wire your project.
    As a computer technician, I have quite a bit of RG58 here which I've tried to use and
    have had it break internally making it a pain to locate a faulty connection.

    You appear to have had much better luck with it than I have. [noparse]:)[/noparse]

    You have to pull all the wires out of the plastic at once. DO NOT USE THE STRING.
    Then separate them carefully. The bundle of wires along with the string tears the plastic.
    But the string alone will kink wires and pull them, possibly causing internal breaking.
    It depends on how old and abused it is. My stuff is from an office, about 10 yearold cat5.

    Looks like someone has more time (junk and parts) on their hands than me.

    Nice links, but the items you linked are not really anything new.

    One was a led spiral wired without a pcb.

    Another was a bunch of guitar effects all stuffed into a single box (something that was done with the prop already "open stomp" http://www.parallax.com/tabid/699/Default.aspx

    The last was a tube amp of some sort. Perhaps someone could make a tube amp with the prop, but not me.

    I just focus on using the prop projects with a minimal amount of other parts.

    The fact that I don't use circuit boards in my design is due to cost, not due to a lack of skill or capability. I would like to use circuit boards, it would sure save me many many many hours of wiring.

    But I am getting better at making the wiring neat and organic looking.

    Haven't made any songs .. i did a mix with the video of "jason nevins its like that".. i played two of the "blackbox", clock synced, live..
    Its challenging and fun, what I would really like to try is like 10 of them all linked up.

    Most of what you saw on hackaday was what i have.. on you tube.
    It was mostly improv on what dials and sounds I played at times, once you play an instrument enough you can do stuff..


    No one joined my band so i stopped playing. :0







    I should make this into a pcb... yet another project...
