    I use 11 Leds connected parallel. If you want to connect the Leds i series this is the formula -> adapter output voltage / LED voltage = Total LED's

    You will need audio split adapter (http://www.amazon.com/Spliter-Adapter-Supports-Microphone-Function/dp/B00812V25Q/ref=sr_sp-btf_title_1_12?ie=UTF8&qid=1378719396&sr=8-12&keywords=audio+split+adapter )

    Nice!, so you had a lot of wires soldered to the middle pin of the tip31 transistor, and to the positive end of the battery? and with 11 LEDS you didnt need any resistors for each parallel led circuit?

    Yes there are a lot of wires soldered to the middle pin of the tip31 transistor and to the positive end of the battery.

    very cool! do you have one LED in each pexiglass, which you have 11 of them, and is just connected in series, but just in each separate pexiglass?

    You can try it but I don't know if it works. –źnalogue of Tip31 is 2N6123.

    What he has done is re-created/re-designed motadacruz's project: https://www.instructables.com/id/Music-LED-Light-Box/
    Although, the circuit is missing the resistor for the LED's.
    Could go a step further and make it stereo in the re-designed circuit by Ovrlrd: https://www.instructables.com/id/LED-Light-Box-Modified-Circuit-Diagram/
    Although, the circuit is still missing the resistors for the LED's.

    This might have been a better concept if he had integrated dmallen's VU meter project into this one: https://www.instructables.com/id/VU-Meter/
