LED Matrix & POV PCBs up for grabs!
I've been working on an uber-clock project recently (it's going to be really really awesome!), and it entails a very interesting display -- a 5x16 array of SMD LEDs.
I tried making a homemade PCB, but it was impossible to use, so I'm sending my order out to a fabhouse for some real ones. While I'm at it, I'm offering you, instructablonians, the chance of a lifetime: Owning one of these awesome* boards!
For $18, you get the PCB and 100 red SMD LED's! (LEDs courtesy of T3hMuffinator) -- this price pretty much covers the cost of the board & shipping.
For an extra 5 bucks, I'll stuff the board with the LEDs for you.
(The 5 bucks is to cover the solder paste, and the labor involved :P)
It definantly needsto be stuffed with solder paste, the parts are very close together.
It is litterally just the LED matrix, there are spots for it to be connected to a controller board, where the resistors would lay.
EDIT: Heres the schematic, sch file, and the board.
EDIT2: New board design, much much more compact! 3.15" x 1.20"!
EDIT3: Just in case we get a flood of replies, I'll repeat 'Muff.
He's supplying the LEDs. They're avaliable in red, white, yellow, and 1 other color. They're from [www.select-technology Select Technology] (eBay UMO88)
EDIT4: I also have controller boards availible. They're basically an AtMega8, resistors, header pins, power, etc all on a board the same size as the array. (not an easy task!)
They're $18, PM me fore more details
I also have some POV boards availible. They are uber-compact, at only 0.8"x0.6"! They come with 10 SMD LEDs. They cost $5 a piece. Just add the Attiny13 & power!
For $15, you get the POV PCB, the LEDs, 11 Male & 5 Female header pins, a DB-25 connector, an Attiny13, and its socket. Its everything you need to use this PCB. (Note: you need a parallel port on the back of your computer in order to use this board to program the uC)
Its a very self-explaintory PCB, which makes it great. Its compact size is great for a few different things
An instructable is coming really soon on making/stuffing/using it, so don't dispair!
