Make an led light bulb - without soldering !!
What you need is - 4 leds, one 10k 1/2 watt resistor, one 0.22 uF 400 volt capacitor and one wire connector !! This runs on 230v AC. For 110v AC, cha...
Connect a positive leg of one led to a negative leg of another. This is one pair of 2 leds. Make as many pairs as you wish but limit it to 14 pairs...
See the finished product pics in daylight.
Looks much better in real life !! But see the pic ! Tip 1: U can use this simple wire connector concept even for ur 6V & 9V projects and avoid sold...

hi pandyaketan, i have 6v dc 8mm 24 white led board, can i connect this board this method.
Since you have DC circuit on the 24 LED board, you would require a diode bridge. So use the Part-2 version (see next instructable).
You can use upto 30 LEDs, so 24 will not be a problem or even 8 mm should not be a problem.
Make sure to get the diode bridge and circuit polarity right!
hi pandyaketan, thank you. can i use 8mm white led or not . how many 8mm led connect.
Hi pandyaketan, can i use 1 watt 22k ohm resistor and 224k 400VAC capacitor, and if i use 1 watt 22k ohm resistor and 224k 400VAC capacitor how many led connect.
1 watt rating resistors are better than half watts and i definitely recommend higher wattage resistors, since they can stand more heat and therefore, last longer.
However, 22 kilo ohm resistance is not required, since you are using 4 LEDs here...They may not light up, since they reduce all the required current.
So i have used only 10k resistor.
You can connect upto 30 LEDs (15 pairs) on a single 224k 400vAC capacitor.
So you would require only 1 kilo-ohm resistor, rated for one watt, if you plan to use 30 LEDs.
Hi pandyaketan, thanks for sharing such a great idea. i will surely do it for myself. For my curiosity, i just want to know that what if i use 10k 1W resistor? And what will be total power consumption if i runs it for an hours.
10k, 1 watt resistor provides lower current, so your leds may not light up.
Power depends on how many leds u plan to use.
