Human: Perspex LED light and sound activated bar Completed Assembly in operation: https://youtu.be/d8P9hhyOXbk and another sample https://youtu.be/7bf3BYers34 I apologize for the low video quality. My tablet cam did not do justice to how it looks and sounds. Material: 1 IKEA Moslanda 115cm picture shelf (black) 1 Arduino Uno 1 Transformer 2 1M 30 Pixel/M WS2812 LED strips (total of 52 LEDs required) 26 3/4" Thick Perspex Cast Acrylic Blocks 5" x 3" 1 MAX9814 Microphone Amplifier Module AGC Auto Gain Control for Arduino 1 470 ohm resistor 1 100 uf capacitor 1 0.1 uf capacitor 1 Rocker Switch Package (L x W x H) 5.0 x 2.8 x 0.8 in. 1 Pushbutton Switch Package (L x W x H) 2.4 x 1.4 x 1.2 in. 1 48 in. x 3/4 in. x 1/16 in. Aluminum Square Tube 10 #8 Pan Head Sheet Metal Screws Printables: 26 Perspex Mount* 8 Led Strip Retainer 2 Center Support 1 Left Angular End 1 Right Angular End 1 Center Connection Junction 1 Arduino Screwless Hobby Top 1 Arduino Uno Mountable Bottom All pieces are designed to print without support. The design includes fine details to enhance FDM bridging abilities. *Perspex is cast clear acrylic and may vary slightly in thickness. Three mount widths are provided for a snug fit. Constructing this project requires some effort, but the maker community's willingness to create complex and wonderful things should not be underestimated. I posted the circuit diagram and sketch on Autodesk Circuit, but it appears to have vanished during the move to Tinkercad. If there is enough interest, I will recreate it on Tinkercad and discuss the assembly process. You need an accurate means to saw finely cut slots in the IKEA shelf for mounting and aligning the block retainers. A few skills are involved, but nothing insurmountable. Other than cuts and soldering, everything else snaps, slides, or screws together. Update: I found my design post on Autodesk Circuits with an early version of the sketch after searching for it. For some reason, Autodesk assigned it to a fictitious author during the migration attempt. The signal generator shown is only used for simulation purposes and not required in reality. Note that the revised sketch and light bar design use 13 WS2812 per strip versus the 12 shown in the circuit diagram. https://circuits.io/circuits/4038568-arduino-neopixels Attribution to Robert on Youtube who provided the design inspiration and original sketch, resulting in this 3d printed version of it and the modified sketch.
