@magorwilly1 The datasheet for the LM3915 has information on adding more LEDs. A quick google.com search should be able to help you find it "lm3915 datasheet"
I think so, but I am not sure, maybe I tweeked something here or there... it's bread boarded in the video, I believe the one built as the schematic may be less sensitive than the one in the video, since it was designed to be attached to a bike wheel.
EDIT: You could use the dual LM339 8 LED VU Meter circuit, thats what im doing. I have the LM 3914 circuit, much simpler, but i think the LM339 is next in line...
Couldnt u use a circuit mic for the signal instead of a speaker input?
Hi. good job. How many led can you use? is that the maximum?

Is that a Peak Detector on there?
Can I use a transistord peak detector instead?

Hi
Can you give my the manual construction and the circuit for the microfone led vu meter.
Thanks

one half of those 3 months has passed :)
there is no chematic of vu-meter with mic on net, i try to find it every once in a while, but no can do...
i dont mean to annoy you, but hurry up!!
haha, sorry...
all the best,

Heeeyyyy man, message me for the schematic URL or just check out the battery powered VU meter instruct able comments.
(or just check the video description)
Peace

thats it man!!! Thanks
i'll make it with 10x10cm clear plexiglass squares stacked vertically with little gap between them, and a blue diode in every piece...
i can begin now...
thanks
