I've been wanting to use clear casting resin ever since I saw it used in this brilliant Instructable by Koogar. Before I took on something as big as Koogar’s project, I wanted to start small so I came-up with “LED Resin Cubes”.
The idea behind the LED Resin Cube was inspired by a mercury switch that I found at my local electronic store. I love the simplicity and look of this switch and wanted to incorporate it a project so you could see the switch in motion. As the switch is made of glass and fragile, it’s pretty important to encase it in something strong – hence the clear resin.
Check out the video below to see the LED Resin Cube in action.
This is a really easy project to do and the end result looks pretty cool.
Step 1: Things to Gather
1. LED lights.
I used these lights from eBay but it is up to you what type of LED light you want encased. The LED's I used change colour everytime you push the swich, and for the last change the lights flash!
I used these batteries from eBay. They are small button batteries that can re-charge and throw out 3.7v which is plenty to power an LED/s
I used this charger from eBay.
4. Mercury Switch
5. Female 3.5mm power jack
6. Male 3.5mm plug
7. Copper wire.

8. Clear casting resin.
This can be purchased from your local hardware store or eBay. I used "Diggers Casting Resin" which I purchased from my local hardware store.
10. Casting mould.
I used a small, square, plastic container which held chicken stock cubes - see below
1. Soldering iron
3. Wire cutters
