Hi
anyone out there who can wire up a MIDI xylophone for me?
I have the unit and the arduino mega 2560 and PCB board
just need to find somebody in UK who will do it for me, just needs some soldering and wiring and some resistors, sadly the guy that did my last one is unavailable now
Thanks
Can I suggest that you post some more details and perhaps 'photos of your last one so that we can have a better idea of what is required
Hello andyroo66
Take some time and look in the WWW for a local Maker Space or a local HAM radio group.
Have a nice day and enjoy programming in C++ and learning.
Thanks here is the inside of the working unit. Just making another one on the same principal
here's a link to where i got the original project idea
please see below thanks!
That looks quite large and would be expensive and awkward to send to someone, so finding someone local to you sounds like a good idea. I am in East Anglia or I would offer to help
As an alternative, you could teach yourself to solder which would be a better idea in the long run
HI UKHeliBob
Thanks.
I'm not up for the soldering as I have more than enough on my plate with other projects and for the moment this is the only soldering project I have
The unit in question is H=11cm, L=77cm, Depth=31cm so not that big, weighs 2.7Kg
I looked on Evri (The new Hermes) and can send it signed for for £7.75
Would you still be interested in doing it if I cover the postage both ways and the cost for the job ? If we can find a figure that works
Thanks!
I would gladly do it for free but I foresee problems as I would want to test it before sending it back and have no MIDI equipment to do that, but let's start with the basics. For instance, have you got a schematic of the project ?
yeh completely understand that
the only thing I have is the original instructions off instructables
The code in that link looks quite suspect and I don't honestly see how it could ever work
For instance, the pinAssignments array is defined to be of type char and has 6 elements. A char can only hold a single character but the code assigns 2 character values to 12 elements of the 6 element array, thus writing to memory beyond that allocated to the array
Is that the code that you used ?
hi
i have made a different code that works on the first xylophone I built, I dont remember the modifications I made now but it works
thanks anyhow for looking
Thank goodness for that. If you post it here I will see what I can do about testing it without a MIDI device. From the little I know about MIDI the messages should be visible in Hairless MIDI
It is a shame that the circuit is shown only as a Fritzing diagram but fundamentally it is a simple circuit
Have you got all the hardware required including the cable and what looks like a stripboard laid out in the shape of a breadboard ?
I note that in the original the piezo buzzers were opened up. Does that need to be done or have you already opened them ?
Hi
Have everything apart from the "wires" as follows:
Arduino Mega 2560 & USB
breadboard
1mOhm resistors
the piezos are all opened up and attached to the xylophone
all is needed is wiring it up as per the circuit (photo of "other unit" is hopefully helpful)
Yes Hairless MIDI plus LoopMIDI (Tobias Erichsen) can show the midi messages are working
I can load the arduino code to the board myself
I wouldn't let you do it gratis
Hello you two
This is not my construction site.
But isn't it easier to solder cables to the piezo elements and distribute them to the Arduino via Wago terminals without shipping all the hardware. You can take simple dupont cables to do this.
Have a nice day and enjoy programming in C++ and learning.
Im gonna be away for a couple of weeks now, Will make contact again when i'm back. No idea what a Wago terminal is
It might be easier if I find someone local
thanks all
Enjoy your break and make contact again if you still want to follow up on this
I really think that finding someone local to you would be the best option as doing anything remotely is going to be difficult and you can see the level of detail needed
I agree with @paulpaulson that there may be easier ways to construct this project than using the breadboard PCB, hence my questions
