<\/a><\/figure><\/li><\/ul><\/figure>\n\n\n\nWhile I didn’t get my main materials in time for the maquette, I still wanted to make a to-scale model of it , so I made a terrible cardboard mock up just to see how I liked the size of it. In general, I like the scale, though I wish I could make the base of it less thick front to back. I might be able to shave off a half inch or so to depending on how I mount the pump. There’s also a chance I make it slightly wider to accommodate an extra channel in the acrylic, though it wouldn’t add more than an inch or so to the width.<\/p>\n\n\n\n
Supply List<\/h2>\n\n\n\n
- ESP32<\/a><\/li>
- 12V 4.8W DC Water Pump (3m head)<\/a><\/li>
- Tubing (5\/16″ ID x 7\/16″ OD to match pump)<\/a><\/li>
- 12V 2.5A DC power supply<\/a><\/li>
- 12V to 5V buck converter<\/a> (need 5V to power the ESP32 and LEDs)<\/li>
- MOSFET<\/a> (to control the 12V water pump power with a 3.3V signal from the ESP32)<\/li>
- Waterproof 144\/m addressable LED strip<\/a><\/li>
- 1\/4″ acrylic
- Each of the 3 layers is 5.5″ x 13″ so a nice 18″ x 24″ sheet should be good, with some extra room for mistakes.<\/li><\/ul><\/li>
- Something to glue the acrylic layers together (will likely use Weldon #4<\/a>)
- Useful resource: http:\/\/www.daniellewethington.com\/gluingacrylic\/<\/li><\/ul><\/li>
- 3D printing will be done at the makerspace most likely<\/li>
- On\/off switch<\/li>
- Maybe a button or two (could use for different modes or something)<\/li>
- Maybe an encoder or potentiometer (brightness control?)<\/li><\/ul>\n\n\n\n

I was hoping to get some of my materials in time to have something more physical for the maquette, but they only just arrived about 20 minutes before class. Instead, the bulk of my maquette is in the form of a more detailed CAD model. I plan to 3D print and laser cut the pieces… <\/p>\n
