Ghani Lawal- Some resistors are giving values that giver by over 50% of ideal values when measured by oscilloscope after being soldered
- Documented the soldered
resistors that are and aren't defective
- 7 were defective
- -----R1, R2, R20, R21, R58, R39, R40
- 43 were not defective
- -----R13, R18, R31, R36, R51, R41, R50, R22, R35, R53, R23, R24, R28, R29, R30, R34, R48, R4, R11, R65, R43, R45, R47, R54, R61, R66, R67, R68, R69, R70, R71, R72, R73, R74, R75, R76, R77, R78, R79, R80, R81, R8, R82
- Interesting, the resistors that appear to be defective are at the first stage of their respective spectrum filters and connect either directly to Vsig or via one resistor
- ***Figured out the issue, this resisters are not defective, this is a design mistake, need input buffers will go into more detail tomorrow
- Analyzed measured capacitor values, will go into more detail tomorrow
Troubleshooting!!!!!!
A project log for Music Spectrum and dB Visualizer
Receive input from a 3.5mm jack, divides the music into 7 frequency bands, shows the loudness of each frequency band in DB using LEDS.
