A ceiling lamp based on a resting rowing shell from underwater.
Size
23" diameter circle-ish; that means 75.4" circumference, ie 1.9m
- also see #Power Supply size
Electronics
LEDs and Arduino ordered from adafruit, order 469886, justthis1please!
Arduino
- Arduino Micro w/o headers - $24.95
Arduino Size
0.7" x 1.9" x 0.4" (17.77mm x 49.52mm x 11.59mm)
LEDs
white
white colour backlight

- 3801-3981-0277-5296
- same chip, so if we assume same-ish current then 1800mA 60mA/each -> 30ish
won't work
- 25 LEDs mount flat - $39.95
- 25 @ 60mA each = 1.2A for whole chain
- also needs connector - $1.50
Power Supply
100W / 120V = 0.83A 10A * 120V= 1200W
- needed 5V 12V supply, Adafruit doesn't have, ordered
- 2A for each
- http://www.ebay.com/itm/12V-5V-AC-Adapter-Hard-Disk-Power-Supply-For-Hard-Disk-Drive-Black-T1K-/380647145774
- order # 4293-5514-3610-6371
Power Supply size
10.7 x 4 x 3cm
