Step 6: Assembly

Once everything else is done, the assembly is fairly straightforward...

Insert the LEDs into one end of the plastic holder you made and the card into the other end. 

Put the leads from the LED around a battery and slide the battery up so that it is nearly touching the LED itself.  I snipped the ends off the leads of my LEDs with scissors to make them a bit shorter because they were a bit long and I didn't want them touching an of the other metal in there. 

If you are worried about the life of your LED, make a pull tab to keep the light from turning on until you're ready.

I bought a couple of those old plastic covers you could get for a school report from Office Depot.  It's a thin clear plastic and it's nice a smooth so it slides out easily.  When you're ready to insert your LED into the clip you simply place this tab between one of the leads and the battery, leaving some of the tab sticking out so that you can pull it out when you want to turn it on.  I use a piece of paper in the picture here instead of the plastic, but you get the idea.

When you close the clip it should be right at the top of the battery where it meets the LED.  The LED should light up without flickering unless you have a tab in.  If you use the tabs make sure you pull a few out after assembly just to make sure you're inserting them properly.

That's all there is to it.  Best of luck on your DIY wedding!

Hey I wanted to reach out to you and thank you for all your help, I know it's months later but I actually did this for my wedding and it came out amazing. I did a few things differently and made some mods. I went through a lot of prototypes in order to try and build on your concept. (the pull tabs weren't working out well for me it made the connection for the LED too loose when I pulled the tabs out and the light would flicker and sometimes go out completely) I added switches so I could make them all ahead of time and not worry about batteries dying or the pull tabs ruining the whole thing. Then I made mods to that idea and just used cr2032 cell battery holders and then all I had to do was slide a battery into each one the day of, I had the catering hall do this when they set up the card table instead of wasting my own time. It was real simple and worked amazing. I soldered the LED directly to the battery holder and krazy glued the battery holder to the inside of the binder clip and just bent the LED up into place. I cut the polypropylene rod out completely because I think my LEDs had a wider angle of light distribution so it actually lit the acrylic up perfectly without the rod and all I did was use the binder clip to hold the card in place. I still have prototypes with the switches, they're really cool, and I have some of the actual seating cards I used for the wedding still. Im not sure how I could show you pics if you're interested in seeing it. I'm happy I came across your instructable it gave me my own touch on our wedding day, and I wanted to say thanks. Oh and btw I suck at dremel engraving so I used a KNK Zing machine for engraving it came out so professional looking that way. You gotta see the sample I did of me dremel engraving vs the actual finished product.
Can you send me a picture of your modifications? robertbischoff2562@gmail.com
I know nothing about electronics but can you put an rgb led in there and it'll still change colors or do you need other things to make it change colors
you need another circuit to make it change color. Most simply, a microcontroller and a single resistor are all you need. In total, $0.86 for the microcontroller and a penny for the resistor. The other thing worth mentioning is that you would need some soldering. If you are more interested I could send you a schematic and the if you really want, the program to make it run. Cool idea :)
Hey what microcontrollers are you using that would be so cheap? I am very interested in doing that for my wedding.
I would use an attiny13 like this one http://www.mouser.com/ProductDetail/Atmel/ATTINY13A-SH/?qs=sGAEpiMZZMsgSGrx0WqTbM6D4zKh2wZJ <br> <br>I have bought them for as little as $0.25 each for a 100. Buying in bulk saves a lot. Other chips would work too but this is the easiest to work with in my opinion. It is also very low profile and can be hidden inside the clip still. It looks small, but it is totally easy to solder still. <br>As for the RGB LED, I would order those in bulk too. Instead of paying outrageously high prices for RGB ones, you can bring them down to a few cents each.
how have you placed LED ports on battery?????
Hi I'm just curious to know. What other materials could i get to replace the Polypropylene Rods
hi i need the schematic for controlling rgb led through microcontoller can you send it to vignesh220ece@gmail.com
Hey I know my post is about a year or two off but I came across your instructable while searching for an LED cube instructable and coincidentally I just got engaged to my gf back in February. I am looking to use this idea for both my engagement party this summer and wedding for next summer however I already purchased the acrylic from rid out (after a serious amount of looking around no one was as professional and cheap). My problem is the website listed for the LEDs doesn't work anymore apparently, and I found some other websites but I don't trust the sources because the websites look real shady. Do you happen to know of anywhere else cheap to order the LEDs from? I'm probably using white (cold light not warm light) if this doesn't look good I'm probably going with Blue, so I don't want to take my chances because I'll probably be making several purchases. Any help would be greatly appreciated, and by the way this was a really clever idea.
This is probably too late, but for anyone else wondering this I buy most of my LEDs from either <a href="http://www.mouser.com/Optoelectronics/LED-Indication/Standard-LED-Through-Hole/_/N-75pv5?Keyword=LED&FS=True" rel="nofollow">mouser </a>or<a href="http://www.taydaelectronics.com/leds/round-leds.html" rel="nofollow"> tayda electronics</a>. They are both very legit, cheap, fast shipping, and high-quality.
I honestly haven't purchased any LEDs in a while so I can't give any advice beyond the calculator I mentioned in the post. You might want to try asking the question on the general forums or looking at some of the other LED 'ibles for a recommendation though. Obviously there are a ton of projects with LEDs on here so I'm sure someone can recommend a good vendor.<br><br>Sorry I couldn't help, but best of luck with the project!
Hey, thanks for the quick response... I found a spot pretty good prices but the LEDs aren't water clear is that an issue? they are 55 degree viewing angle and 4,000mcd .
I made a few of these today but found that either the light doesn't diffuse enough or I had the engrave a lot deeper than expected. Did you have this problem too? Yours looks much prettier...
Awwwsome! Unique idea. We had some friends marry recently and it seems as though they are mind-readers because they used our song choice, game choice and other ideas we had already discussed for our possible, future wedding. Now we are on the hunt for differnet ideas so not to be known as the copying couple. Lol. This is a GREAT idea we will add to our new selections. Thank you!
Alright, first I want to say this is a FANTASTIC idea and your parts list and instructions are VERY helpful. That being said, I'm kinda stuck on this step. Well, sort of. I have it all assembled and it lights fine. But when trying to do the pull tab setup, there's just too much grip where the clip holds onto the leads and battery, and it moves the battery along with the tab. I tried paper and plastic with the same results. Any suggestions? I'm testing my LEDs tonight to see how long they will last, but I'd kinda rather have the pull tabs so that they can be brought to the reception venue before the day of if necessary.
Awesome idea! We're currently in the process of planning our wedding and when we were trying to figure out how to decorate the tables this Instructable popped into my head. I remembered reading it when it was first posted and thinking how neat it was but never thought I'd be able to make them.<br><br>I can't wait to get started on this project.
these are definitely a great way to put them together. I have made some similar before. however to save time on this step ... my husband &amp; I have a laser engraving business ... where we can laser engrave all your cards for you, and laser cut them to the size and shape you prefer. it's always an option and may even cost the same amount that you may pay for just the acrylic cut alone. just wanted to let you know that there are more options out there, that may make it easier for the newlyweds and still be able to do DIY projects all in one.
Don't bother with LazersEdgeEngraving, poor communication if they ever get back to you
JerseyJ, thanks again for this instructable. I just got married on June17th, and these place cards were a huge hit. It was a Friday evening wedding in a modern space and it fit in perfectly. I will upload some photos once I receive them. It was well worth the effort as many guests took them home as wedding favors. The lights I tested stay lit for over a week (although they get dim after a few days). I pulled out tabs inbetween the battery and light about 6 hours before the wedding started and they were just as bright at the space. If your event space is very bright, you wont get the same effect as a darker room. I saw several photos on facebook the next day of just the place cards. Thanks again, Paul
Awesome! Definitely would like to see some pics when you get the chance.
Has anyone tried to do this with Acid Etching ? Just had the idea and it might be much much easier and quicker with a similar effect.
good-thank you <br>
im doin this project for physics :)
Thinking about doing this for my wedding, really cool idea. Would love to see some photos of them being used on the day.
simple, practical, very cool.<br>thanks for sharing.
Rediculously kewl 'Ible! Thanks for sharing!
The most clever ideas are the simple ones. Now, I can't wait for some one I know to get married so I can jump in to assist with this idea. It would normally be impossible to convice a guy to assist on a wedding but this is proof that with the right mix of techology, you can get a guy to do anything.
This project looks fantastic, and I tried making one myself using blue LED lighting. Looks great! My fiancee liked the way my prototype one looked, and I am most likely going to make these for our wedding reception coming up next year. <br><br>The only modification I made was using a &quot;rectangular LED&quot; and just cutting a notch in the acrylic glass. I lined the bottom edge (covering the sides of the LED) with black electrical tape before putting the name plate in the clip/holder. The rectangular LEDs have really wide viewing angle and with a brightness of ~2500 mcd, they look great. This also eliminates the need for the plastic tubing to hold to card and LED. Thanks for the Instructable, and great job!
We need to talk. How do I sell this idea to my lady. She won't let me make anything for our wedding and I have the itch to do something on my own.
make one and show her how nice they look? When she sees them for real she may change her mind lol
Simple, but very nice.
Thanks for all the positive feedback everyone. If anyone actually decides to undertake this for their own wedding or special event feel free to ask questions.
This was a great idea. This is one of the ideas I proposed to my fiancee that she was ok with. I might be interested in seeing photos of your event space. I was worried that if too bright, the LEDs might take over all the photos. I hope you didn't feel this was true.
They're definitely not bright enough to overpower the event space. The LEDs will light up the cards nicely but the light is dispersed enough that it won't turn your tables into huge glowing masses of light.
Once I got some fully assembled, I noticed the polypropylene tubing dimmed the LEDs from most viewing angles, but kept the place card very bright. I had put together a few by etching a place for the card directly onto the LED. I felt it held the card well enough, but the light was overpowering.
I just wanted to say that these instructions are great. I can tell that you put a lot of thought into it and tried a lot of different options. I tried modifying things here or there and when it came down to it, your original ideas ended up being the best option. <br><br>The only things I found to save time or money was using a roll of foam mounting tape and buying polypropylene tubing from Ace Hardware or possibly Lowes. I got the 3/16&quot; ID and 5/16 OD tube. It is rigid and holds the card well. In addition, it holds the LED very tight (although you cant push it up all the way up the tube). This tube has the same cloudy color that keeps the light from shining off to the sides.<br><br>I have spent about $85 on this project ($8/100 leds (ebay), $13/100 batteries (ebay), $59/155 name cards (ridout plastics - best prices), $5/2 rolls of foam tape (Walmart), and $1/5 feet of tubing (ACE). I was able to borrow the other equipment like the dremel. I believe I could make about 85 finished products ($1 per card), but I will probably only need to make 70. <br><br>Thanks again. Ill let you know if I need any more help, but your instructions are stellar.<br><br>
Glad to hear it's working out! Make sure you post some pics of your event, I'd like to see them in action. <br> <br>I did check out some LEDs on eBay. My only word of caution is that I found some were not as bright as advertised. Make sure you test your cards out in normal and dim lighting prior to the event to make sure you're getting the brightness you need out of them. And remember to use the lumens calculator for your LEDs. Something may be listed at 10,000 MCD but have a very small viewing angle and thus not sufficient to really light up the card, while an LED listed at 2,000 MCD with a very wide angle will put out alot more light.
I agree with you on this. I think mine were rated at 5,000 to 10,000 MCD at 160&deg; angle, but I don't think they are as bright as advertised. I think they are great, but I would not want them to be any dimmer. I tested a few batteries and LEDs that stayed bright from 4-7 days. I still plan to use the pull-tabs so I can fully assemble them a week before the event (June 2011).
How about a blob of hot melt glue to attach the card to the LED? Quicker &amp; easier than the polypro rod, and would probably look at least as good.
I was trying to avoid things like glue. As I said in my 'ible, I'm not the most artistic guy in the world and when glue got involved in some of my prototypes things started to get pretty messy :) <br> <br>But if you can do it and make it look good, go for it.
Or just saw a slot in the LED itself. Drop of superglue, and voila. Should be ok with a 5 mm led and 2mm card.
Amazing, amazing idea!! I'm not even close to being married (I'm not even dating anyone) but I like LEDs and I'm going to have to ask my future husband if I can do this--cause it's just too cool to pass up 8D <br> <br>Just one question, and I might have missed something (it is late and I'm pretty tired) but what did you do with the silver handles on the binder clips? Did you cut them off or take them out? <br> <br>Sorry if this is really obvious...
You just kinda squeeze them together and pull them out. Next time you're holding a binder clip you'll probably do it and say &quot;duh, I knew that&quot; ;)
...duh, I knew that! I just grabbed a binder clip and figured that out. Just wondering--are these pretty stable? I know a binder clip is stable on it's own but with the card and everying does it get top-heavy or anything? <br> <br>Thanks for answering so quickly!
Well they're the biggest clips they make so it does provide a fairly wide base. The battery is in the base and the acrylic doesn't weight all that much so it isn't too top heavy but I'm not going to say it's the most stable thing in the world either. The only time I had any issues really was when I was transporting them to the venue in a box and they all had a habit of &quot;dominoing&quot; and falling over. <br> <br>Believe me when I say I considered a large variety of options for bases and styles of card. The main problem is that you are making a lot of these things and they have to look GOOD. You don't want to stick something out there at your wedding with globs of glue in spots, or cardstock with jagged cuts, or have some huge thing concealing the battery.
wish i had seen it before our reception I could have done this but in a lighter purple for our theme colors you got my vote :)<br>keep me in mind when voting i built the 3 tier fruit wedding cake
