Finaly finished my LED Matrix board and 16F876 board after a little bit hard soldering job

Now that looks very familiar!

Takes a while soldering all those LED's doesn't it?.

Looking good though.

Thanks Nigel, Yes and i did the LED matrix board over 2 or 3 weeks, all the track cuts the first day, some wirelinks one day and some another day and so on, and finaly all the led's the last two days. I have also built the one mainboard, one IRboard, keypad board, LCD board, Switch board and LED board,so far.

Oh! - I designed and built the board in a single afternoon!

Mind you, I've been soldering for a LONGGGGG! time!.

Since you guys are playing with an 8x8 LED matrix, I've got quite a few demos on YouTube that might be interesting. Mind you, you can connect directly to the PIC without limiting resistors, taking full advantage of the self-limiting FET's in the PIC output. All the 8x8 demos connect directly to 2 full Ports.

Nice work, I used the same technique which you do by adding jumpers on top of the vero board other than making messy in the underneath of the board.

I do this when I don’t have money to buy matrixes. I like home built led matrixes other than ready made ones.

I just copied Nigel´s layout from his tutorial hardware page
