Hack an LED screw globe and make it portable.

I recently got my hands on an LED globe which came with a remote.  After a lot of use in the kid’s room it finally stopped working.  I think the reason why is that they have a dimmer in their room and the LED globe didn’t seem to like it too much when it was dimmed. 

Instead of just throwing it away I decided to see what was inside, and if there was any way that I could hack it to make it portable.  Well there was a way and here’s how to do it.

So if you ever have a need to turn a room blue, or like the look of the red light district – then this project is for you!

Enjoy

Step 1: Parts to Gather

Parts:

1. LED Globe – Ebay
2. 9v battery
3. 9v battery terminal - These can be purchased at any electronics store (or scavenged from a broken toy)
4. Wires
5. Toggle Switch – Ebay
6. Box.  This could be anything that the battery can fit into.
7. Heat-sink.  I used a video card one from an old PC - Ebay
8. Screws


Tools:

1. Soldering iron
2. Pliers
3. Wire cutters
4. Sharp scissors
5. Screw driver
6. Phillips head
7. Drill
8. Hot glue

Step 2: Pulling Apart the Globe

This is the fun part!

Steps:

1. Un-screw the bottom of the globe.  You can see that I tried to cut mine off first before I realised that you can just un-screw it!

2. Carefully pull out the insides.  Most of this is capacitors so be careful as they could still contain a charge.  Cut the red and black wires.

3. Ply off the plastic diffuser with a screwdriver

4.  Unscrew the circuit board from the heat-shield and lift up.

How long does the standard 9V last? I'm thinking of modifying the use rechargeable AA's instead.

what i mean to say is when i turn on the switch on the side it just starts flashing through colors. what should i do?
Try making sure the battery in the remote is not dead, or the paper is not separating the connection if you have not used it before. Also, distance matters; too far away and it won't send the signal.

Would love to see another method of control other than the Commercial remote. Overall I like this conversion.

I do wonder about the need for a heat sink. It would be interesting to measure the temperature inside the box both with and without the heat sink. I also wonder if some larger, ni-cads or Li-ion batteries wouldn't be a better choice. Those 9V batteries are expensive.

I did hook-up the led's without the heat sink and those puppies do get hot. You could probably get away without having one but i think it looks pretty cool with it.

Re-chargeable batteries would be a good idea - you could add a plug into the back of the box to charge them.

the 9v battery I used was about $5 so not too expensive really.

I'm confused.. i got mine to work but the remote simply will not work. it just started on its cycle and won't change to the color i want... did i just rip out something i wasn't supposed to?

Hey there,
Not too sure why that would be happening. Have you tried to remove the battery and attach it again? Make sure its a new 9v battery. There isn't much you can rip out as the circuit board is one complete part with just a couple of wires sticking out the back.
Are you using the same light as I did? If not, maybe you need 2 9v batteries to get it running right. Check your wiring again and make sure that nothing is short circuiting.
Hope you can get it to work!
This is super awesome! I had an idea just like this but it uses LEDs powered by an Arduino.

Thanks.
Nicely done, I am adding this to my list of my next 'fun projects' !!

Cool.
Cool Idea, was it the same LED bulb that you won in the Lamps & Lighting contest :)
Yeah is was! Good memory Tarun.
I won a couple of them so I think I might hack that one as well.
Awesome :). I remember things I admire, I just loved your PIR airplane hack.
