manos,
sorry, I don’t have any new PCBs and I won’t do any new ones. But you can take the Eagle files and do it on your own.
Cheers,
Alex

Hello Alex, Great gadget you have there, Have you got any new PCB’s I need two of them and I don’t know if you can provide all the parts as a kit? Is that possible?
Thank you.

hi Alex,

Cool…. is a very interesting project. I might want to try it too..but izzit possible for me to get the PCB board?

thanks.

Funny… was looking over your stuff and noticed I had some 5 x 7 matrix displays laying around… and an arduino…

I might try to replicate this onto my own MCB as an Arduino Shield possibly… would make it quite unique…

Hi mariadele,
you can not connect the mic directly to the controller, the signal is too small. I used the LM386, an OP-AMP, to amplify the signal.
Here is the link, where you can see, how to assemble the mic, the LM386 and the controller.

Another mic with amplifier that I found lately looks very promissing. It’s made by the guys from Sparkfun.

Hi! Could you tell me how you connected the electret to the arduino board? Is it enough to connect the electret mike to the board to give arduino the input of the sounds detected by the mike?

I am going to use it to make leds light up, and the leds are doing ok, just I don’t know how to make it all work (hardware) with a mike.

Thanks really, I have been sweating on this a while

Hi Thanos,
looking at the Kingbright datasheet, it has a common kathode per row. The Everlight (ELM-2081SURWA/S530-A3) has a common anode per row. So try to get another dot matrix or invert the outputs of the controller.
Cheers,
Alex
