Hello everyone. Could anyone clear me up about the type of rechargeable battery being used with the D-Box? I can't find specific info in the parts list.

Thank you very much in advance!

P.S.: Obviously i missed the D-Box kickstarter and now would like to attempt to build something similar myself.
The parts list only mentions a rechargeable battery, but no detailed specifications/technical data/manufacturer...

We use a USB rechargeable power bank from RS Components, 2200mAh:

That said, many phone charger batteries of this sort will work just fine. You have probably already found the build manual on GitHub, but in case not, it's here: https://github.com/BelaPlatform/d-box

The manual makes reference to a few cable assemblies we put together, but most of these can be reconstructed fairly easily, e.g. 2 piezos connected together on a 3-pin connector to the Bela audio input. The main thing that will be hard to get separately is the touch sensors on the top. They're a custom design, though at some point I hope we can offer them for sale separately because they're useful for things besides just the D-Box.

    Thank you for the hint, Andrew.
    Those touch sensors on the top seem the main input source right away, i find performances such as the one right at the beginning of your Youtube D-Box presentation most fascinating, as this guy goes into exploring new hand-played musical territory right away (no correlation to club music anymore) https://www.youtube.com/watch?v=JOAO-EUtrGQ using mostly the top sensors it seems.
    Maybe could you indicate, how they are constructed?
    Or a broader question, could there be more detailed specs or a Mouser / rs-online part list for
    the capacitive touch sensors (even just what you custom-built them from?)
    the force-sensing resistors (0.5" round, with long leads pre-soldered) and
    the potentiometers
    used?
    Bela cape arrived today. I am very excited and have time until end of Feb to create a hacked instrument suitable to fit to needs for contemporary dance... Thanx again.

      so @andrew ... i assume those touch sensors are something like linear soft pods glued on top of FSRs?

      Andrew is actually away at the moment and may not be able to reply, so I will throw out there what I know: the sensors on the D-Box are custom-built capacitative touch sensors which can sense X-Y position and pressure. They are not currently available anywhere I'm afraid, though this may hopefully change in the future.

      Thank you @LiamDonovan - that is good info! Would be nice to see those controllers for sale, however, there is a ton of info on custom building those i find. I guess i will have to attempt to do this myself, or is there a timeline for an eventual release?

        jayrope you're not wrong, it would be nice! There's no timeline currently in place though, sorry.

          andrew I'll let @andrew reply about the touch sensors, but for the FSRs, potentiometers, and a bunch of other components which are useful to have with Bela, take a look at our experimenter's kit parts list.

          How long will Bela run from a 2200mAh battery (with ordinary cpu usage)?

            When not using a passive speaker connected to the Bela cape, it is probably going to be around 4 hours (BBB power consumption is about 470mA, plus the cape).

              9 days later

              jayrope Yes I do intend to eventually release the touch sensors, along with Bela and Arduino examples for reading them. Too many other things on right now though! I'd say early spring 2017 would be a realistic timeframe of when these might be available to buy. In the meantime, a chip like the MPR121 will give you some of this capability, and you might be able to use conductive paint in the right pattern to get slider-like functionality.

                  Thank you for the hint about the MPR121, andrew . Unfortunately i have no background in mini pc programming other than touching the BELA now (and the Hoxton Owl before). I am quite glad, that PD works with libpd on Bela, otherwise i would have to start from scratch.
                  Looking at Adafruit's and Sparkfun's versions of the MPR121. Seems, that Adafruit provides more of an explanation, how to approach this. Adafruit's version seems to live with 5V, but yet i have no idea, how to incorporate this functionality into a PD patch...
                  Argh.
                  Shame Berlin hasn't anything near something like the London Music Hackspace, but maybe i can visit you guys end of January...
