I would like to share one of my favorite projects how to make a bottle lamp. You do have to invest about $15  for a diamond bit, but the bottle lamps can be made for less than $10 and they make amazing gifts or sold for a profit at craft shows and Etsy shops.
Before we start i made this instructables to thank my first 100 subscribers i got featured twice and won a contest i couldn't have done it with out you guys thanks so much now enjoy your instructable

Step 1: Overview

Theres lots of ways to make that special lamp of yours. heres a few ideas of what can be accomplished with a little creativity and a well explained instructables like this one ;)
<p>Excellent ible!!! At what speed should you run the drill press?</p>
I put the drill press on the highest speed but I would check the chart I posted below <br><br><br>http://www.diamondsure.com/Techniques.shtml
<p>Thanks for your response! , and your instructable !! Looking forward to this one.</p>
Strange question but what liquid are you using in the 3 example, garage door lube doesn't say me too much...
<p>I've got a Chateau Petrus 1952 bottle which will make a great lamp. THX</p>
<p>I would like to make lamp style number three but I cant find the LED base. Can you tell me where you got it at or how you made that part? </p>
Thanks! This really helps. + it is super cool. I have been looking into night lights for a while.
<p>This is definitely really cool but I think a short strand of Christmas lights and some glass beads will work instead of the LEDs and soldering. Wish I was on your level though! </p>
<p>Looking at this again for the socket where the lightbulb goes into is that just resting ontop or did you glue it to stay straight?</p>
<p>It looks like it might be above my pay grade, but it looks really cool! I voted for you on both items. Good Luck! :)</p>
<p>thank you so much!</p>
<p>thanks! don't forget to vote for me :)</p>
<p>You don't need 4 batteries to run one LED in the base of the bottle. Use a simple Joule thief circuit to run one or 2 3 volt bright LED's</p><p><a href="http://www.ebay.com/itm/131115025121?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2648#ht_272wt_922" rel="nofollow">http://www.ebay.com/itm/131115025121?ssPageName=ST...</a></p><p>The chip can use up to 5 volts and double the voltage to the LED's</p><p>To calculate LED's with wall wart supplies, divide 3 volts into the DC voltage and run that many in series. Each LED should pull about 20 ma current and you may not need any resistors.</p>
<p>You should never run an LED without resistors - you *need* to limit current - setting the voltage can't do that.</p>
I used resistors I will check my post again but almost positive I said I used resistors if not then I apologies but I completely agree with you
<p>Yes, you put them in the circuit diagram. Good practice. Some LED's have an internal resistor but unless you know this for sure, you need to limit the current.</p>
<p>Go here: <a href="http://www.hebeiltd.com.cn/?p=zz.led.resistor.calculator" rel="nofollow">http://www.hebeiltd.com.cn/?p=zz.led.resistor.calc...</a></p><p>In the series LED section enter 6 power supply volts , 3 LED volts and 20 ma current. Zero resistance! This is a page from a manufacturing site. The other calculator site always adds at least a one ohm resistor, which could be a real wattage headache if you are using a lot of power. It is wrong.</p>
<p>So where's the other 3 volts being dropped?<br><br>From the site you list: &quot;Voltage drop is usually 1.9~2.1V&quot; - the change in &quot;resistance&quot; for the 0.2V band can be huge, and nothing like the the same as would be expected for a purely resistive load. LED's are semi-conductors, current needs to be restricted.</p>
<p>Series means more than one LED in sequence in a circuit. Put 2 in and the second one drops the other 3 volts. Put in more and you get negative resistances because you are cutting current more. Eventually the LED's will not conduct at all. Next closest resistor = 1 ohm, but that's just a technicality as there are no negative resistors.</p><p>Using V = IR a resistor or an LED must drop the rest of the voltage in excess of the voltage of the first LED. Since the second LED can drop all 3 volts there is no need for a resistor..</p>
<p>Ah, you didn't mention a second LED. However, you still have the problem of not knowing the exact voltage drop across the LED, especially with white and blue LED's where the voltage is typically 3.0-3.5V - so two LED's in series may not work on a 6V PSU and if you used a 7V PSU you may have 1V too much.</p><p>Some reading for you:</p><p></p><p><a href="https://forum.allaboutcircuits.com/showthread.php?t=61168" rel="nofollow">https://forum.allaboutcircuits.com/showthread.php?...</a></p><p><a href="http://forum.allaboutcircuits.com/blog.php?b=378" rel="nofollow">http://forum.allaboutcircuits.com/blog.php?b=378</a></p><p>However, as you seem against resistors in series with LED's, I won't comment further on this subject.</p>
<p>yep and thanks</p>
<p>Where's the resistor on your computer plug? Light bulb?</p><p>The voltage drop of the LED given by the manufacturer is the current setting. You can run 40 3 volt LED's in series on 120 volts just like light bulbs. Add a rectifier in series to block reverse voltage.</p><p>Watch out for red, green and yellow plain old LED's as they run on less voltage than a bright LED. Usually 1.5 to 2 volts.</p><p>I've been running four 10mm 3 volt bright LED's in series on 12 volts DC for years now. </p>
<p>Yeah, what ever...</p>
Yes thanks for the idea but I prefer the simplicity of mine
<p>I understand, your forte is making the lamps. But there are a lot of people who might like to use less batteries later on. Send them to me if you can!</p><p> Also you can run a few LED's off of line voltage through a high voltage rated capacitor too. Did you ever see those lamps with top and bottom lights? Could be some ideas there. Let me know if you are interested. Nice Instructable! </p>
Thanks and ya I will send them your way good luck
<p>I have 2 Absolut Vodka bottles, and I would like to make them into a pair of lamps, but do you think it would be possible to put LED in the bottom with a lamp shade on top and use a three way switch ? </p>
sounds like it would work when you make it post a picture sounds awesome good luck and dont forget to vote for me!
<p>I Voted for ya, I will have to get the Diamond Drill bit so I can get started, thank you for the ideal. </p>
<p>no problem and thank you so much for the vote send me a picture when your done i would love to see it!</p>
<p>You do know you can buy the guts of a lamp separately in case you don't have a lamp your not using right?</p>
<p>i know i get them from homdepot thanks for the comment don't forget to vote for me :)</p>
<p>Are you serious? You advocate destroying <br>a good working lamp to make an LED lamp that will be out of style next year!</p>
<p>Why not? If you have something you don't like, you either give it away, throw it away or hide it away - so why not convert it into something you *do* like?</p>
No it's just one way of making it you can buy pieces from home depot to but some people don't have that luxury to do so
<p>Do you use any insulation for the LED wires to keep them from shorting out? </p>
I use electrical glue or tape or heat shrink tubbing the majority of the time
<p>Very awesome idea! I've made alcohol bottle lamps with just LEDs. Haven't thought about adding the lamp/lamp shade on top though! Nice addition. Here's my lamps http://cookingcircuits.com/home/2013/8/29/alcohol-bottle-lamp</p>
Nice lamps! And thanks
<p>Great instructable! Really liked it! The only big problem will be make this just after empty the bottle! (JK)</p>
Hahhaha thank you
<p>Pour water on the glass while drilling. if it heats up the glass will crack.</p><p>Keep water away from electrics if using electric drill.</p>
Yes I forgot to say that thank you it helps a lot to prevent cracking I usually use a wet rag or something
