This is the second part of the music visualization series and in the video above i have shown how you can make a simple VU meter by using the ic called LM-3914 or LM-3915. The part 1 is basically about how you can make the simple and cool looking VU meter by using the arduino microcontroller link to that is given as and now we will see the step by step construction of the VU meter STEP 1: Watch the Video STEP 2: PARTS LIST To make this cool looking UV meter we need these following things 1.LM-3914 IC 2.Breadboard 3.Copper dot PCB 4.18 pin IC Holder 5.Resistor(1.2k & 4k ohm) 6.Potentiometer (1K ohm) & Knob 7.Audio jack 8.Dc jack 9.LED (6-Green & 2-Blue & 2-Red) 10.some connecting wires TOOLS REQUIRED 1.soldering iron 2.wire cutter 3.soldering wire etc... STEP 3: SPECIFICATION OF LM-3914 & DATASHEET When looking at the LM-3914 ic datasheet these are some important feat...
The simple ballon lamp is made from the ballons and the 12v led strip with the led driver Step 1: WATCH THE VIDEO After watching the video follow the steps as Step 2: THINGS NEEDED TO MAKE THE BALLON YOU NEED THE FOLLOWING THINGS 1.BALLON 2.GLUE 3.THREAD 4.12V LED STRIP 5.12V LED STRIP CONTROLLER 6.STICKING TAPE 7.POWER SUPPLY 12V Step 3: PROCEDURE OF MAKING making the glue ready to do this take the glue in a empty box and mix it with 1/3 part of water and them shake well and make sure the glue is mixed well in the water the if you want you can add some colour in the solution and make it colourfull after that is done you need to follow the instructions for winding the thread on the ballon as i have showen in the following video let it dry for some 12-15 hours then by using a sharp pin pinch in the ballon and after the ballon blsast ...
