So i will accept all flames since this is my first post. Got a little project me and my eight year old are working on. Wanting to build a circuit to take the line out voltage from a phone or ipod and through a splitter, play music to her radio while having 4 led ouputs, left and right channels whilst each channel is divided into two filtered outputs for bass and highs( these will drive seperate led strips) . We are going to preassemle on my breadboard so here is where i am at on this so far:
1. Wanting to utilize the 12 volt led strips that are premade (https://www.superbrightleds.com/mor...power-led-flexible-light-strip--nfls-x3/1465/)
2. I already have some 741's and some 386's as well as tip31 and 120's. ( this can be changed)
3. I was thinking that from the output we could run into dual 741's (left and right channel) to amplify the output to around 1.5 volts max then into a potentiometer to adjust sensitivity.
4. following the 741's i could run the output into dual tip31's then to dual the lm386'ssetup one for an RC high pass and RC low pass.
5. basically each channel (left and right stereo) would have one 741 to boost the output the the tips 31 that i can adjust the voltage prior to input to avoid the saturation point of the tip31 and into the 386's to meet the 12vdc requirement of the led stip while allowing me to create a simple RC filter for high/low.
I am not entirely sure of the output current draw of the led strips, have a feeling this is a limiting factor.
I am open to ( that is a ridiculous idea). I haven't been in this game so this is just using the Google FOO. If it pleases the audience i would appreciate any ideas to simplify this idea, Would really like to be able to run this off a 12vdc power source that i already have available.
