Hi everyone. Today i will show you how to make cheap attractive musical purple night lamp[mini audio system+music activated light+purple night lamp]
Step 1: Things You Will Need to Make This Night Lamp
Lets start making this musical night lamp. things you requried to make it are:-
1.a cardboard box of medium size
2.plain pcb(4)(with each holes seprated)
3.one speaker(4 ohms)(3watts)(this are not critical measures of speaker it can be little more or little less than this values)
4.one switch with three modes and three pinouts(one can easily get from handmixture or regular two way switch will also work)
6.8 leg ic holder(if you want)
7.3300uF electrolytic capacitor but is voltage should be 10V only.
9.two to three high bright 5 watt leds
10.some connecting wires
11.one three voltage led(any colour)(it must be of 3v only)
12.power supply of 12v 1A (this arrangments of all this parts and this night lamp circuit will only works on exact 12v 1A of power supply)(one can get this adaptar from setup box power supply adaptar or it is also available from decorative led adaptar)
13.aux wire for audio signal in.
14. Purple colored tape
Step 2: The Circuit.
Make all the arrangement according to the above pictures of this musical night lamp circuit.
only changes from the images of circuit is to replace 100nF capacitor with 3300nF capacitor of 10V it work best for this circuit.
Step 3: Finishing It.
Now when all the circuit is ready which is shown in before steps then place all the circuitary parts and ic in the box.
place the two pcb on the top of the box with placing 5 watts of leds in it (2 to 3 leds.each 5watt) by making the triangle shape by pcb on the roof(YOU CAN USE SOME OTHER ITEMS LIKE PHOTOS, CARDBOARD SHEETS WITH HOLES IN IT ETC).
place the arrangment of speakeron side walls of box and 3v led light on speaker to make the spraker attractive.
if you want to keep potentiometer of brightness adjustement then you can around 50k to 100k volume knob type potentiometer in series connection between any two 5watt led.
now make all the connection according to the before steps shown in picture and fit all inside the box.
At last after fitting all connections in box apply all around purple colored tape on the box to make it look attractive.
Step 4: Testing It.
HOPE YOU LIKE AND ENJOYED MY PROJECT
THANKS FOR WATCHING IT.
