I have 4 of these as well, I got them from the same source as sprite.

They are old bus station displays, that’s why they’re so cheap.
If you watch closely in the video’s you can see the burnt-in leds from the bus-numbers etc…

actually he didn’t buy ten 32×16 led matrices but 8×8 and combined the 8 of them into a 32×16 display…Just thought to mention that :)

@ Wwhat:

Considering that part of the project started out as funded by his job and them paying him to do what he enjoys, as well as the “I built it my goddamn self” bragging rights. Add that he probably had the discretes and the AVR’s already, so just had to buy the (Used and discounted) led displays (5€ each, so 10 * €5 = 50€) it more then balances out. (Comes out to about 12 USD per LED Display + AVR). Worthwhile I would say.

It’s interesting as a hack and he (and we) learned some stuff and he showed prowess, but really, by the end he must have put more cash in the project than the cost of a 22″ LCD, that’s the kind of thing that would hold me back, basically it’s done already (LCD=dotmatrix too) and available at shops, and I don’t really see a need for it.

@ Adam, I figured that out during the whole CAPSLOCKS day thing. Even posted about it. All you need to override it is a user css and adding a
* { text-transform: none !important;}

line to it. Poof, no more forced lowercase or caps on any site.

Also, Sprite’s the man.

Very awesome. It’s amazing how you can still make out what pretty much everything is on such a low res display. Very cool.

Wow… just realized that HAD doesn’t actually upper->lower case the stored input. It is handled with a style of text-transform: lowercase;
