Tiny and smart designs always showcase great solutions of how to find space for everything.
Solved:
The drivers have to be place as far as possible from the pickups
If inside The drivers , have to be pointing into an hole
Insulate your speakers with proper insulated cables
A rubber support
7Wx2 amplifier to a speaker of 4 Ohm 10W

Solved:
Noise is elimanated not only by using the bela preamp shield but:
Each humbucker has to be wired alone (not in series) to avoid a noise sounding like it needs to ground
Use proper isolated wires for it!
The wifi dongle can be an interference for the pickup noise
Unfortunately, It seems the Sensitive buttons placed closed to the pickups gives noise too, I do think the wires are not properly isolated and therefore, gives a not of noise. The problem could also extend to the isolation of the buttons, which are placed into TPU recycled rubber platforms I might have to make them thicker or more filled
New issues:
Pick up position isn't acessible
I am using batteries with to much amperage (2A), that gives an extreme noise to the sound!
The analogue pins of this shield seems to have a connection problem in the pin 1and 0. At this moment I am using pin 2 and 3 for the pot meters.
Future considerations:
To make more acessible the mantainance of the humbucker without having to reassemble the instrument completely.
To find a solution to acess easier the IDE

zoom32: input was to loud
zoom33: some beap low, the bela was connected to te computer
zoom 34: the bela was
zoom37: I discover the pickup is getting noise from the wifi dongle
zoom38: BELA CONNECTED TO THE BATTERY!
ZOOM39: TRYING WITH A BATTERY OF 8000AM CONNECTED TO BELA, THE sound SOUNDS GREAT!
ZOOM40: Bela connected to a 800A 5V battery with the wifi dongle. The wifi dongle seems to provoke a soft low beat.
Conclusion: It seems the cause of the loud was using 2A in the minibela

was the preamp the problem?
21-07-2020Noise control is a nightmare. Therefore, I spend 6 months delaying a big problem: noise hum. I tried to prioritize problems by delaying this one for later. In the summer the bela platform team has sent me a product to try from them. Time to solve completely this problem!
