Juno Speaker

Juno is inspired by a song of the same name by British Progressive Metal band Tesseract on their 2018 album Sonder.

I wanted to focus my project on the physical form of a Progressive Metal song because of the ideas the genre represents and exhibits.

Forward thinking composition, modern electronics and expertly designed instruments.

The qualities contained within Tesseracts music holds ground in my personal beliefs as a designer.

I utilised these qualities in the conception, development and production of Juno.

Step 1: The Champ

Build 'The Champ' using the instructions provided in the kit.

Step 2: 3D Print Enclosure

3D print the enclosure!

Preferably using PVC water soluble supports for easy and clean removal.

Step 3: Install Potentiometer

Test fit the potentiometer in the enclosure, with the amplifier mounted close to the potentiometer, but with enough room to both have reasonable cable clearance and space to solder and mount. the other components

With the potentiometer knob facing away, trim the wires to size, and solder ground, wiper and positive terminals accordingly.

Step 4: Audio Input

Repeat the same test fit method as the potentiometer, and solder the pin closest to the input to 'INPUT' and the furthest one to 'GND'.

Step 5: Rocker Switch and Micro-USB

First, solder a jumper cable from the positive pin to pin 2 (indicated on the back panel of the switch)

Solder pin 2 to a 6-8cm long wire, which will be trimmed to size later on.

Repeat this with another wire on the - (ground) pin.

Solder a 3-4 cm wire from the VCC pin on the USB Micro board to pin 1 on the switch, and double up the - pin on the switch with a wire coming from the GND pin on the USB Micro board.

Step 6: Securing Components

Use included fixtures (Nuts,washers) to secure the Audio Input and the Potentiometer to the back panel.

Thread the USB board through the switch routing, Connect a micro usb cable through the back panel to the board to secure a position.

Use some high-strength epoxy to secure the board to the back panel from the inside, making sure not to get any epoxy in the port.

Leave to dry for 1-3 hours. Leave it to set overnight before extended use.

Secure the rocker switch with the included circular nut.

Step 7: Speaker

Solder speaker Positive (+) and Negative (-) pins to the SPKR + and - pins on the board.

Apply high strength epoxy around the around the circumference of the opening on the enclosure,

Leave vertically to dry for 30 minutes, then leave overnight with the speaker flat to firmly secure it.

Step 8: Complete!
