Orange led strips
These were used for the Halo 4 launch UFO thing and we're donated to the space afterwards.
They take 24V and come in multiples of 6 leds (the strips can be cut up).
30 of the 6 led units takes 0.52A so roughly 0.02A per 6 led unit.
Each 6 led unit is 5cm long.
So roughly 0.33A per meter.
We've got 31 Strips left with an average length of roughly 1.5m so 43m in total.
For 9 14 segment displays we need roughly 33.3 meters of strips.
I've put the strips in a box with a do not hack label - if there is no progress on the 14 segment display project after a month or so they can go back to being general access.
