Liven up Record Players with stereo LED VU meters
The practice of listening to records seems to ebb and flow, falling and rising in popularity - however it can still be a lot of fun and a great way to enjoy music from the past.
And to make this even more enjoyable, you an add a pair of VU meters to the turntable as demonstrated by Michaël Duerinckx.
VU meters are useful in that they not only add a visual representation of the music, but also indicate the signal level of the music being played.
For his turntable modification, Michaël uses the equally-classic LM3915 logarithmic LED display driver IC and builds a pair of the reference circuits into the base of the turntable - with the LEDs spread around a part of the circumference:
Having a turntable with a wood surface makes life easier however the LED placement is up to your imagination. Check out the video below for a demonstration of the VU meters in action:
