Introduction: HACKED!: Flickering Light Bulb for Halloween

It is time to scare your friends. In this project I will show you how I "hacked" a normal led light bulb. This way it will flicker like the lights in every horror movie when something bad is about to happen. It is a pretty simple build if you have some experiences with electronics.

Step 1: Watch the Video!

The video already give you all the information to get this build right. But I will cover the most important ones once again.

Step 2: Order Your Parts!

Step 3: Build the Circuit!

Here are the two schematics that I created during this project. The first one is just a quick test with an Arduino Uno. The second one on the other hand is my final design which will later control the led bulb.

Step 4: Program the ΜC!

Here are the two Arduino sketches that I created. The first one is only the test code. The other one is made for the Attiny85.

Step 5: Success!

And there you go. Now you can scare your friends with your own flickering light bulb.

How can I modify this to work with a 120V north american LED bulb?

I think you only have to measure the voltage of the leds and buy the correct MOSFET

The ATTiny powers up with a voltage regulator, the 7805, so check that the led's voltage fits on the regulator voltage range

Where did you get the large plastic "cracked" bulb from?

That's very clever, I like you used a random function, it couldn't be any closer to a real flickering lamp. Be careful with the Chinese lightbulbs though, some of them are authentic death traps.

add that, some creepy music and you are good to scare everyone!

also, you can use a neon light transformer to do the same effect, if you arent a tech savy person!
