You're done, just plug it in the phone line and enjoy! (also works with DSL lines)

It's not like a 100W light bulb, but it's perfect for when the lights are out!





Adjustments.

These settings will give you a very bright light, but in some cases you might get busy line on your phone.

To fix that you can change the R1 and R2 resistors.



The higher is the R1 and the lower is the R2, the brighter is the light. But it's more likely to get busy line.

If thats your case, you can put a higher R2 resistor (330ohm).

If you still get busy line, put a lower R1 resistor (3.3K ohm or 1K ohm)





If you don't want to test a bunch of different resistors, just stick with R1 = 1Kohm and R2 = 270ohm. This will work for sure, but you will lose a little amount of brightness!





Any question, just leave a comment

Thanks



PS: -I don't know if this is legal or not in your country, you should check it out yourself, please don't flood the comment page saying that this is illegal as if the World were ruled by your country's laws, because it's not!!

-I've built this and it works perfectly. I receive and make calls at any time when this is plugged to my phone line, no interference at all.

-Also, if your phone line is equivalent to mine, you don't have to change anything. If you really think any component is not necessary, give it a try and post the instructable so we can learn from it!



PS2: I am not incentivizing anyone to "steal" energy from the phone company. Use it with intelligence! If you keep it plugged for the whole day and 1000 people from your city do the same thing, the phone company will start charging for this energy and everyone loses.
