Arduino Soundlab

thingiverse

A DIY sound lab kit featuring an Arduino Nano as its core component, designed by rgco from Instructables. The project showcases a custom box and printed circuit board (PCB) specifically created for this purpose. Video: https://youtu.be/RxOWTbz_H9Q Notes: The initial PCB version included the LM386 amplifier, but it was later removed in favor of a 5V regulator to accommodate a 12V power brick. This modification allowed the unit to operate on a single power source without needing an external amplifier. Printing/Assembly: Eagle files for both the schematic and PCB layout are provided. The creator opted for the toner method when producing their board. The 3D printed box is straightforward, requiring no support during printing. To assemble it, users need to drill out the PCB mounting holes using a 2.5mm drill bit and create threads with a 3mm tap. M3 screws are then used to secure the PCB in place. Parts required: 1. Arduino Nano 2. LM1117-5 (5V SMD regulator) 3. 0.1uF Monolithic capacitors (3 pieces) 4. 100uF 16V Low Profile capacitors (2 pieces) 5. Tactile switches (24 pieces, each measuring 13mm x 6x6mm) 6. Black button tops (10 pieces) 7. White button tops (14 pieces) 8. Panel Mount Jack Socket (1 piece) 9. Panel Mount DC Power Socket (1 piece) 10. Linear Slider Pots (9 pieces, 26mm travel each) 11. M3 screws (4 pieces) Software: Due to a design error on the board, pins D8 and D11 were swapped. To resolve this issue, an updated sketch was created, which is now included in the project files.
