Oozing Goo - The Lava Lamp Syndicate

 I was able to convert my heritage century into a LED color changing lamp for fairly cheap! roughly $25!!

This was the first part I purchased, its a 50w ceramic heater. It gets hot so a dimmer is a must use. You can see the size comparison with the standard bulb. It wont fit in the standard 32oz or 52oz "premier" bases, I tried. The century has a larger bulb opening allowing you to screw it fully in. Ebay Link

Next purchase was the LED rings. They are 70mm halo rings made for car custom headlights. Cost about $19 for a set of 4 rings that come with a remote 24 buttons and IR remote box and some adhesive pads. I did purchase new IR remote boxes with 44 button remotes that have more color phasing options and dyi options cost under $5.00.  Ebay Link

Here's how it looks with the globe off. The ring fits on the base inner rim perfectly. You can see the ceramic heater is showing its red hotness!  The one thing I was worried about is the LED ring wiring being so close to the heater so I took some tin foil and rolled it around heater so it keeps the heat down for the wiring and flowing upward toward the globe. Speaking of wiring, the only modification I made to the base was that I pulled off the cord plug and then feed the led wiring thru the hole. Then pulled out all the slack of the led wires and tied it off to keep the wiring away from the heater.

Here are a couple pics of the 3 main colors look and a couple videos of the color changing.

Finished product

Notice tight-fit cooling fan location which is a carefully designed position for airflow to cool the SCR dimmer and remaining components. Probably not necessary but better to be safe when it comes to heat and electrical components.

8 conductor cable exiting the back (4-color change-2 lamp-1 ground-1 shield)

This is the ideal way of creating a color change Lava Lamp when the room is limited in the base of the lamp and/or heat is an issue.

This particular one I built for my Mathmos Lunar conversion project.

Talk about a tight fitting component layout~!

barely room to wire it

I still have a variety of these smaller heating elements if anyone wants to try this for themselves

Thats fantastic work man..

How did you wire the leds to 120v

Im very interested in your heaters if still available. 

Text would be great

step down transformer from 120 VAC to 12 VDC then to a remote control for LEDs
