Got my pcb proto ready. This is a Audio Visualizer that will be available as open source. It has two display. The first display will show a stereo VU meter, the old fashion way: imitating a needle.. while the other display has several features one of those is a stereo 69 channel spectrum analyzer…and it’s really fast! so that’s 140 channels in total! ( L+R VU, L69 +R69)
The pcb will include hardware to implement line in, line out, mic in…input for potmeters and switches and two outputs for pixelled matrix or ledstrips………..So excited to get this out there!
The PCB was sponsored by @PCBWay
And the main sketch that I started with was created by DIYlab.de
Hi Mark,
I have done a little research on your dual screen audio analyzer and want to build something similar. I also saw a version on youtube done by clever3d that you commented on. On his version, he could switch either display. Is that your design with modifications or something different?
Are you still making boards, populated?
Best regards,
Bruce
Sorry, been a while..but yeah…clever3d used my design. I just released a newer version, board are available populated, no more need for the audio board as it is integrated in the pcb
