Beautiful device and complete project combining multiple disciplines - very nice. The 16 neopixel is a particularly nice-looking addition. As a musician, I'm surprised you went with capacitive sensors, since piezoelectric sensors would allow you to do velocity-sensitive pads, and might be cheaper. (Although piezoelectric might have "bleed" between pads without shock insulation.) Fantastic project overall though.
This is a very cool project and an excellent video. Thank you! *And* as if that wasn't enough, as the cherry on top, your pronunciation of "solder" was perfectly correct :)
I totally love your video, I am building one as soon as I get the parts from Adafruit, purchasing NOW!!! I have a 3d printer so I will print the bits, however, I ABSOLUTELY love the aluminum so would it be possible for you to provide me with 6 pads at a cost?
May I know how to add more touch pads to the MPR121 sensor? It seems that there are only 12 points in it to solder. Correct me if I'm wrong. Great build. Keep up the good work.
I’ve hacked your midi sequencer and turned into an electronic plunger mute. I’ve added transducer microphones, as I’m using a patch on Max/MSP to use the vibrations to trigger samples and events as the trombone plays into the mute. Three of these mics are used conventionally and plugged into an audio interface. But I’ve added a piezo mic to A1 of the feather and a home made force resistive sensor (FRS for sake of Arduino IDE) to control velocity or other parameters. However I’m having some problems combining sketches for the FRS and Piezo mic, A0 and A1 respectively, with the midi sequencer. Would you be able to help? I want both to send midi data - FRS for velocity (or to control various Ableton knobs/potentiometers). On the last attempt things would work for a while but eventually, the sequencer seemed to crash. Also when trying to connect Bluetooth all was fine, but the Apple midi studio could not see it. I’d appreciate any help or advice.
What's the point of the copper tape? Couldn't you have just soldered the cables to the aluminum? And could you also use aluminum tape wrapped around blocks to achieve the same effect?
The problem with soldering directly to aluminium is that aluminium is VERY good at wicking away heat to the point that it would dissipate it before you could ever get it hot enough to solder to; hence the copper tape. Even then, I was surprised he was able to solder to the tape.
I mean, it's a cool project, but you are giving us hints where to get a 3D print which is like 100 bucks to buy yourself but not where I can get Aluminum CNCed?
From Adafruit site: To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
So just to clarify, if I were to use actual buttons instead of touch pads, I could skip having the capacitive touch sensor, and just solder the buttons directly to the feather, is that correct?
Because the Bt is not a "real" standard... There is too many BT ans too many restriction. I bought an HC5 ( 3$ on amazon ) and it work great on arduino, it work great to pair on my android app but you can't transform an hc5 / 6 to a regular HID device. So you need to buy a more expensive chip like the hid bt chip on adafruit who include a rn42 chip. And in fact, on HC5 / HC6 if you flash the firmwire you can unlock it to use the rn42 ( the price deal is for the software not hardware ). And you want to pair a PS3 / Xbox pad you need another thing, a simple RN42 dont work, cause it use the HCI interface... to resume, you can't buy a 10$ bt pad and use it on a regular arduino, exept if you get a usb shield host and use a BT dongle ( 5$ on amazon ). Its not a big deal but its too big for some project... I actually working on a tiny rc car and i need to create my own pad to use it :/ And of course with thoses software limitations, i can't pair my homemade pad on my computer / phone without "hacks". So yeah, bt is a pure scam, and the price you pay is not for the hardware, but for the software. im gonna try to hack a bt dongle, maibe it work, but there is no real help on the internet, its actually like a week im searching on that :/
Nobock well, i know i'm pretty late but definetly check out the nrf24, its a great transciever and works on 2.4gig. i mean you barely have latency if you do it right and people (to be exact, "iforce2d") have achieved a 29km range with those. they're cheap and small too... sooo good luck with all your projects then! :)
@@nobocks Yes, you are paying for software on HID device. But if you are skilled enough you can try to convert 3$ or 5$ chip to HID device, there are few videos on UA-cam about that.
really awesome dude! this is such a clean, well accomplished project! love it! the machined aluminium really takes it up a notch.

very good demo

You make awesome projects!!!!👍👍👌👏👏
Great project. Thanks for the video and I'm looking forward to trying it, especially the *soddering*! Thumbs up!
this is really very awesome! ❤❤❤❤
you are so expert..
Best project I've seen yet!
Amazing!! I was wondering how to remove the sequencer in the code? I basically want the pads to operate just as simple triggers. Thanks!
Hi did you find the solution? i'm doing the same
Is it velocity sensitive? big question iguess.
I totally love your video, I am building one as soon as I get the parts from Adafruit, purchasing NOW!!!

Awesome!! #StaySUCCESSFUL

what's receiving the ble packet stream? thanks, project is great BTW.
this is awsome
What if you put in a speaker and add the right software and have a portable drum kit or what ever instrument
Neat

can adafruit arduino change with arduino uno+bluetooth, cause that adafruit feather is expensive in here...
is there a how-to for the 16 arcade button version shown at the end of the video? that looks exactly like what i´d like to build.
how to do this with the adafruit esp32 feather?

Where do I find the code? Can't seem to find it on the link mentioned under full tutorial
How do you charge that battery? Do I need to worry about charging circuits/low voltage protection?
From Adafruit site:
To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge.

We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
Do you have an estimate for material costs?
Ignoring the printing filament, aluminium, heat shrink, and wire, $77.20 pre-tax and pre-shipping,
could i use a teensy 3.6 instead of an adafruit feather
From where this beats are coming???
Please i want to put together and octapad that can work with Android midi drum apps, any advice or direction would help
How to get soce code
hi! I was just wondering, is the Adafruit MPR121 12 touch sensor capable of detecting velocity? like piezo sensors?
sadly I dont think so :(
awesome!
So just to clarify, if I were to use actual buttons instead of touch pads, I could skip having the capacitive touch sensor, and just solder the buttons directly to the feather, is that correct?
The Arduino code is written around the touch sensor so it will take some modifications
Is this product open source or have fair use?
Hi! Can it work with mobile ver. GarageBand ?
yes, anything with bluetooth midi support
make this on arduino pls
five? dontcha mean six?
where are speakers?
There aren´t its a MIDI machine meaning sounds are produced in the computer with the data given by the sequencer (:
You forgot there are 6 pads instead of 5
Memes included
The bluetooth is the biggest scam ever :(
Nobock why?
