I am currently working on trying to build a LED spectrum analyzer. I hope it to be a 10x10 at the least and I don't want to use micro-controllers or PICs. I have seen the velleman 4300 design BUT the U2067 is not made anymore . Is there a way that I can multiplex the LM3916? Or should I just use 10 of them and build filters for each channel?
