LED Wine Charms

Light up your holiday parties with these festive LED wine charms!

Step 1 Materials

The LEDs were from an assortment I bought from American Science & Surplus - your basic 1.7V to 3V red, orange, green, white/clear LED.

The 100 & 200 ohm resistors were from Radio Shack.

The 25mm Beading Hoops were from a local bead store and cost $4 for 10.

The only critical component are the batteries, which need to have leads pre-soldered to them at the factory.  The 3V lithium-ion batteries were from Mouser (Mouser part #658- BR2032-1GU,mfr part #BR2032-1GU @ $2.32 ea).

This is perfect especially when, theoretically, you've hit that point in the night where things start to go a bit hazy and you, theoretically, start misplacing your glass...

Great idea!

I've handed these out at two parties now and they seem to be a hit!

They should be very handy at New Year's parties.

Now if I could only figure out how to make them blink...

to make them blink with your circuit you just buy the leds that already blink or change color etc. I have fast flash rainbow and slow flash rainbow that would be cool to try. I take my blinky leds with me to parties all the time. people seem to like blinky

This is very cool and I have a LOT of LEDs lying around. :-)

I did come up with a thought though - couldn't your use the smaller 3v (1cm) coin batteries and a surface mount LED and tape them to the underside of the base?  That would put them shining directly up the center of the glass.

I agree. It would be like using the LED throwies but including them in this project. And with the wire u can simply use the invisible electric tape to make sure it doesnt fall off.

[billr]

What a cool idea!  I don't know anything about surface mount leds, though.

They're a little tricky to work with initially but there's a good kit that teaches SMT soldering and is pretty cheap:

The nice thing is that they're small AND bright for the most part. :-)

using SMD components without a circuit bord (dead bug style) is pretty easy, just use some small needle-nosed pliers, tin the ends, and solder it to whatever u want :D

u should, however order 2 or 3 leds/resistors if ur making 1 (dont count up like that, if ur making 10, order 15) since ul lose them very quick, even with a clean floor/workingspace...

and btw, leds always need resistors, even the green ones! u just need to calculate the right resistor, some only need 50ohm, while others can go to 300ohm
just google it, there are plenty of online calculators to use, instead of manually doing it urself ;)

and maybe add a tactile switch faced down, so the led will light up when the wine glass stands on the table, and goes off the second u pick it up :)

il try to make one of these when i get the chance, make some pictures and upload them

nice idea, nice projec!

[jenjenbug]

These are AWESOME!  And it appears that anyone can make them.  Great ible and idea!

[billr]

Thanks, jenjenbug!

I like your attention to detail + rated ! 4 !

[billr]

Thanks!

i realize the ease at which those batteries with the pre-soldered ends give this project

but i was wondering if you had tried it without the pre-soldered leads and if u had if a 1.5V button cell battery will light up the LEDs well enough or if you have to go with a 3V battery

[billr]

I didn't think a 1.5v battery would put out enough power.  I was going by the info provided by:
http://www.evilmadscientist.com/article.php/throw
, which says red & yellow leds require 1.7v and green & white leds require 3.5v.

I didn't try the 1.5v batteries, though.  I'm sure that 1.5v batteries are available with pre-soldered leads. 

Another option would be to use a battery holder and solder to that.  I would appreciate a link to where I could purchase battery holders for a CR2032 3V lithium coin cell battery.

Could you also use heat shrink? Like these guys have? http://www.heatshrinktubingdirect.com/

Andrew,

Heat shrink was the first thing I tried but I didn't like the way it looked.
