The current-production stribe circuit is usually here: http://www.soundwidgets.com/stribe/circuits
The .pcb files can be opened in ExpressPCB, a downloadable circuit-design tool (http://www.expresspcb.com/
). It's basic, but it's free, and quick to learn. I would've had to buy the Pro version of Eagle to design a board this large, meanwhile ExpressPCB is free. Then you can download the latest prices and find out how much your design will cost in different quantities and options. Very convenient for prototyping.
*4 ways to help:
1 ) Add a new circuit to the proto area
- A MIDI interface (remember, 5V .5A USB power - not sure what I'm already using, but you might need to add external power cause something tells me I'm right at the limit already. But I'm just guessin'.
- 8 Control Voltage outputs to control an analog synth or other voltage controlled device (theremin x 8 )
- audio brain / audio out / audio in? - a teeny synthozoid device along with a preamp and stereo audio ins and outs, e.g. a thumb-sized audio brain
- dedicated logic circuit to replace Arduino stamps (USB and uC)
- Bluetooth? / wireless options (incl battery power, presumably)2 ) Re-design, improve, or otherwise modify the Stribe circuit boards
I am a novice, the Stribe boards are my first circuit board designs ever, and hopefully they will amuse and not anger or upset any actual engineers or circuit-designers among you. Please let me know if I'm unknowingly re-formatting hard-drives with it or breaking some cardinal rule of electronics or something. (On the other hand, I was told there was no way I could run 1024 LEDs off USB power, and those guys were all really smart.)
3 ) Design and/or build a case for the Stribe
I have lots of ideas from picture frames to routed wood custom designs. If someone who's good at drawing in the various CAD tools and wants to whip something up...
Basic specs are the window needs to be 7" wide by 6.5" tall, and the driver board is 7.5" wide x 8.5" tall. Future redesign may include reducing the size to a 7.5" x 7.5" square (once the logic circuit is integrated into the mainboard instead of removable Arduinos). There needs to be a hole for the USB port. I'd like a removable section at the proto area to allowed addition opf MIDI ports etc by user. I want it to look good next to a monome. Wood is nice, but I'm open to other (new/recycled/recyclable/DIY-able) materials, as well.4 ) Integrate the Stribe hardware into your own design
...or base it on a different controller entirely, such as midibox, and just use the 1024 led display capability and the 8 sensor inputs. Or maybe there''s a way to string multiple stribes together by adding external power, or a double USB cable, or...
So many ideas, so little time.
