This version is using PIC16F877 and there is only one device. Use MPASM for code composition and is direct instruction set. Did not use compiler. Code is very compact and fast.
Parts cost is about $100.00 each when parts are purchased in bulk. You can get the kit for $165.00 on ebay which is much less than if buying parts to build one unit. Type in "VU meter kit" on ebay.
Hi, ive just starting working with lm3915 and lm3916, could anyone please tell me a simple way to split the different frequencies up, so the vu meter only responds to the frequencies selected?
If you want to split frequencies ti different areas, you need to use filters (RC filter or CR filter ...). Each filter is use for different type of frequencies. RC filter is mostly used for LOW frequencies, while CR filter is used for HIGH frequencies.
Internet search "multiple feedback bandpass filter" or MFBP op amp filter. Plenty of schematics out there. Send me your email will email you schematic for 10 X 10 unit.
Nice effect. Is this from Circuit Solutions I saw on Ebay? I was thinking of ordering the kit, love that kind of thing. You aren't by any chance the designer?
Do you have to use 16 external bandpass filter circuits for each band, or is the frequency-amplitude calculation being done with the internal software? How are most audio spectrum Analyzer, like this one seen in you tube here, done? by hardware band filter or software frequency-amplitude calculation?
Please I need to know that integrate circuit you used to make the vumeter and that integrated circuit usastes for the filters bandpass and of that oreden are the filters 1º 2º o 3º And the size of the box of leds
All you need is a band pass filter for each band you want. Then you can feed that to a LED Bar display driver, or do it the hard way and use discrete comparators
I am around the strange section of Youtube once more.

yo how are the bins separated? are you doing an FFT somewhere? or are these all VU meters for a bandpass on the audio?
please send schematic :droooool: so sexy when you zoomed out man haha

Yes, the very same from Circuit Solutions.
This video is the result of the early design that was copied from existing analyzers. Then built it better.
Always wanted one of these ever since I was in high school.
So being an engineer by book, craftsman in heart. It is indeed my design. :)

You could have probably achieve the same with at least 100 times less electronics, and a little bit more programming. :-)
_One_ PIC (or some uC) with _one_ ADC and a programmed FFT should suffice..
FelisSilvestrisCatus 4 years ago
Perhaps. :)
This is a true realtime audio conversion analyzer.
Please show me the souless FFT solution that will keep up with true analog conversion.
The FFT software bogs the entire process down.
