LM3915 IC VU Meter Tower

Audio was removed due to copyright. I will leave this video up for the comments and answers to any questions that were asked at that time. Be sure to view a 2nd video in the link below showing more details of this build and also includes audio. https://www.youtube.com/watch?v=afNoje0KEFI This was based on an LM 3915 IC and also worked well with an LM 3916 IC. These were bought through eBay Built using 10 - 10mm thick plexiglass sheets purchased precut to size (5" x 6"), 20 - 5mm LED's (9 colors) wired in parallel for the plexiglass sheets and the arrays also wired in parallel and a 6V DC 1A adapter to power the project. Base of the project was just a wooden frame with some plexiglass added for a top and front panel. Here's the basic circuit I used. http://www.eleccircuit.com/electronic-vu-meter-by-lm3914-and-lm3915/ Some values of the capacitors MAY have been changed to produce a better project to my liking. Try different values to see what works for you. I wired an LM386 Audio Amp before the input of the above circuit. Pin 6 of the Audio Amp was wired to V+ in the top link and pin 5 was wired to the "input from amp" side in the top link. The plexiglass was purchased from http://www.tapplastics.com in the US at a cost of about US $40 plus shipping. UPDATE 7/14/16...The video shows the lowest LEDS in the tower remain dimly lit in dot mode. A fix for this was posted by TheVarooj. Adding a 10k resistor across pin 1 of the IC and V+ will correct this.
