Hi Guys
I was browsing the web, as you do, when I cam upon this 'light organ' circuit. Now I have a particular use for this and with that in mind I have chopped the circuit up a bit. I only require one driver section.
Now as I only need 2 parts of an LM324 I could simply substitute another op-amp couldn't I? So long as it is OK on 12VDC.
The mosfet shown was a single but in another circuit I have it has 2 in parallel so I will do the same and use the IRF540 which I have plenty of rather than the one suggested. The Bulbs will be 2off 12V/24W wired in parallel.
The input will be from an LM358 pre-amp and electret mic to drive this light organ. Other than what I have asked it looks fairly straight forward. My only other question is -
Where does the human voice fit as far as frequency range goes when looking at high pass, low pass, and Bandpass. Which one would best serve the vocal input?
Thanks in advance
regards
