This is a cool little LED lamp that is surprisingly bright and looks cool in any room. The frosted glass of the vodka bottle makes the glowing effect all the more smooth. This is quite a tricky make and will take a lot of patience.
What you will need:
- Vodka bottle ( Mine is Russian Standard Vodka because of the frosted glass but also because it is very tasty :D )
- AC/DC adapter (I bought a 9V one from eBay for £3.50)
- A Switch unit (pretty easy to find in hardware shops)
- 6 LEDs (4 Ultra white and 2 ultra blue... The smaller the better)
- 3 resistors (150 Ohm but it depends on the voltage drop of your LEDs... I will explain later)
- Small piece of protoboard
- Small hand held rotary multi-tool
- small diamond burr attachment (normally used for engraving glass but will work for drilling a small hole)
- Soldering iron (and solder)
- Wire strippers/cutters
- Glue (a strong glue the can stick things to glass)
- A chopstick with some blue-tack on the end (optional but useful)
Step 1: Drill the Bottle
First we will drill a hole in the vodka bottle. The frosted glass makes drilling a little safer and easier but still be aware that this is glass and can break if not treated with respect. It is a good idea to wear safety goggles when going this as the last thing you want is a small piece of glass to fly into your eye! I also put the bottle on a sheet of card in case it broke and I could just pick the lot up and dispose of it without leaving glass everywhere.
As you can see, I'm using oil to aid the drilling. This is optional It gives a nicer finish and helps the glass cut a little safer but makes the process a little slower. To drill the hole you must be patient and not put too much pressure onto the glass. It is a good idea to start with a tool that has a pointed end to progress through the glass and then move on to the wider tools to widen the hole. It took me about 45 minutes to drill all the way through and make the hole nice and neat. Diamond burr tools are used for engraving but can work well for home glass drilling. Silicon carbide tools work too but nowhere near as well as diamond burrs.
