@3dsmo I have a couple of the 3mm version of those panels myself. They're quite nice, including shift registers and row drivers on the back so all you need to do is connect power and a handful of signal wires. And actually, the panels aren't all that expensive either as they're made in china.

[3dsmo]

how did you wire up all those leds

[zawzero]

@3dsmo he didnt, sure electronics did it for him ;)

[Robin4friends]

@3dsmo i hope a giant perfboard

[ketsubansama]

@3dsmo those are led matrixes

[mrfu2]

@3dsmo You can buy it from Sure Electronics with LED cubes plugged into a custom made board. There are multiple LED driver IC's on the Sure board and you can actually connect multiple boards to create a larger LED surface. In the end there is not a single LED you have to hook up yourself, it's all controlled by and connected to LED driver IC's.

not very cheap :s but nice project (the table, not the price ^^)

$22 for a cup of coffee??

[HenryTomasino1]

@HeIsCoolMG The dollar sign is after, which is common to use if you mean cents. 22$ = 22cents

[AgentDexter47]

@HenryTomasino1 no $22 would be 22 cents, 22$ is 22 dollars

I mean maybe it is different where you live

but e.g. 1k ressistor means 1000 ohms, 1k5 means 1500 ohms, and k5 resistor is 500ohm

anything left of the mark is bigger, anything right is smaller

[FrozenHaxor2]

@AgentDexter47 Wrong. The "22$" is totally incorrect. The only correct form is "$22". Also about resistors - 1k as 1000Ω is right, 1k5 as 1500Ω too, but k5 as 500Ω is not. It would be 500R.
