Super cool project
Hahaha comenting on a 3years old post, anyways try Tip122 its 100v & 5to8 A ,
I have a serious question , actually I am trying to make this circuit, and by calculating the resistor watt I found its 144mW for 1k ohm and 14.4mW for 10k ohm, so what watt did you use or can I use 1/4watt for both, please answer. And also in the parts list there is a switch but in the circuit diagram its not there , where should I place it. Again Can I use TIP 122 instead of TIP31 as 122 collector current is 5A continous and 8A peak. And how can I send you PM. Thanks for reading such long post
Excelllent project, and details are easy to undersyand. Thanksa lot for sharing, I was searching for something to secure. This is it.
Why didnt u use any resistors
Excelent knowledge , thanks a lot
Need help,I haven' t use any resistors in my circuit, I used TIP31c & 5cm led cuted from a smd3528 strip red, as I thought that the led have resistors in them, supplu volt is 12v dc from ac to dc adaptor @1amp or from my psu in my pc.I have a few questions1. When I connect the circuit on psu nothing works more over my pc is conducting current.? Q2. What is the quantity of leds can I use as 5cm has 3 led and 1 resistor it drawing somewhere 0.24 watt and 0.02Amp (0.08*3) = 0.24/12v =0.02Amp.and the TIP31c can handel 3Amp ?Q3. Without using any resistor will I fry my audio device ( pc,Mobile)?.Q4. Can I connect additional 100ohm resistro per 1m strip and one 47k ohm resistor to the right prong of tip31c and another 4.7k Resistor at the left prong of the tip31c will it secure the curcuit? Sorry for such a long post plz reply I need help.
Hi Orestis , in you pcb photo there are three connectors , what are they plz reply. Your curcuit seems to be the best one until soo far
I have made with TIP31c , and cut the led strip (1 pice with 1R ,3led) , and connceted with12v dc , my question is how many led can I connect (wants to connect 1M strip )
Very cool n interesting project , I am planing to do it as I already installed led strips on wall and on my gaming desk (self made, self painted) , now I want sound activation on my all led strips but want to use different channels such as ( left audio controlls under desk led strip ,1mtr. Right audio coltrolls leds behind desk, and the woofer controlls the wall led.) But the problem is I am not getting the TIP31 anywhere , so want to know what are the alternatives of the same. There will be 3 separate circuits. Sorry for sush long post, I just want to share my idea.
Here are some pictures, soon I will change the blue leds with red
