Awesome led cube

Step 1: Materials and tools

To make this you will need:
A LED (preferably high power)
a 3 volt coin cell battery
a 100 ohm resistor (anything close to 100 will work)
a momentary or push button switch.
thin sheet metal
plexiglass

tools:
hot glue gun
metal shears
sharpie
saw
soldering iron

 I bought a large sheet of plexiglass and sheet metal at Hobby Lobby for $4. I got a resistor pack , switch x2, LED x4, and battery x2 at Radioshack for $24.

[cullen]

I was wondering if you could use color changing leds adn if the resitors would be the same.?

[wizzywoo]

 hi

[pichu1994]

how much were all of the materials? could you get them for under 40$?

[wazooda]

yeah you can get all the materials for about £10/$16. i'm not sure if rapid electronics ships to america. if it does get your stuff from there it's really good

[Beard of Zeus!]

I did mine for free so far: found a decent green LED @ my house, resistor I had (don't ask), took the button from a broken flashlight, and used a CD jewel case for the sides of the cube. I have yet to complete the outside, though

[Tommyhzy]

I would say the Plexiglas is about $1, the LED is $.02 online to $3 Radioshack, and the battery is about 0.19 online and $2 in stores. The hot glue is $1 for 300 sticks where I come from.

[dunnos]

OMG, could you send me some? ;P

[dunnos]

some of the glue i meant

[Tommyhzy]

Oops I forgot to put the 0 there... It's supposed to be $10 for 300 sticks.

[Kryptonite]

Mines $10 for 50. Sad.

[chosenangelx]

wtf plexiglass is $24 for a good sized sheet led is $2 if high voltage

[Tommyhzy]

Actually, the amount of plexiglas used in this project is surprisingly little, so I would say really, about $1 for what it's worth. The LED you're talking about is probably from Radioshack or any other electronics dealer. If you buy them online, you can get EXTREME discounts, especially if directly from the Hong Kong manufacturers.

[chosenangelx]

im in hk right now led is $2 hk which is very little . ( tri colour is $2 ) is about 1/7 of a canadian or us $

[chosenangelx]

but what thickness? i bought a 10x24 inch plexiglass Y_Y

[Tommyhzy]

Thinner is better, you don't want to cut THICK< CHUNKY plexiglas for hours and hours , do you? But don't get too thin, about 2 millimetres is awesome. (Yes, I'm Canadian, I'll include this so you'll be satisfied: Eh?!! ! :D

[chosenangelx]

did i ask if u were canadian ( i am too.) and thicker is better ( stronger) thinner is better (easier to cut)

[Tommyhzy]

Canadian pride! Anyways, I prefer thinner because what's the use of using THICK plexiglas? I mean, it's not going to be a safe... or a protective screen... Just an enclosing for a hot glue blob.

[chosenangelx]

im making a ball (sphere) looks cooler

[Tommyhzy]

I'd like to see how you make the plexiglas curved. WAIT A DARN MINUTE WHAT HAPPENED TO MY SPELL CHECK BUTTON?!

[chosenangelx]

u buy pre rounded plexiglass duh!!!

[Tommyhzy]

Really? I've never seen it in all the stores I shop in. Does it come in hemispheres or full spheres, ...? I think rounded Plexiglas could be used for something very cool in the near future... Note: I think Plexiglas is spelled with 1 "s".

[chosenangelx]

u could always just buy a hamster ball

[chosenangelx]

2 halves makes it easier to put led in

[chosenangelx]

buy 2 halves , look in electronics section of hardware, used to create firm light domes 4 lawns take them apart glue 2 haves tghr

[Tommyhzy]

^{HaHAHAHAHAmster ball! But you DO realize they're PERFECT with that door abut except for those air holes... That could make filling the ball with hot glue a pain.}

Thanks for the domes tip, I appreciate it.

[nomooremr.niceguy]

Hobby stores often sell plastic balls in two hemispheres. Sometimes they'll have various sizes. I got one that was 80mm. I'm not canadian, I'm Texan. (Canadians and Texans seem to be the most prideful about where they're from of anyone. I can't say who has more pride. Just thought I'd mention that.) But back to the point. I just thought I'd throw that out there for anyone that was wanting the pre made balls w/o holes.

[Sponzyparadox]

LOL never met a New Yorker then have ya? Another place to look would be at holiday ornaments they are round and you can put stuff in them. IDK just a random though

[nomooremr.niceguy]

I have met New Yorkers before. And as proud as they are, it's less common for them to be as proud as a Texan or a Canadian (No offense intended). But then again it may also depend on the area of New York they come from. And you're right, about ornaments. I have looked at them. They are affordable, and come in multiple sizes. You have to be careful about the glass ones, they will break, with or without stuff inside them. Their greatest downfall though, is their general inability to come apart and go back together. Getting the battery assembly in and positioning an LED inside them could be possible, but tricky. But I like how you think. Keep it up. Happy tweaking, Sinisterly, The Not So Nice Guy

[Tommyhzy]

Wow... It's so hard to believe that all this started with a simple mention if an idea... By the way I'm actually 13 years old (seriously) But hey, it's never too late to start being innovative! Oh and it's just me, normal 13 year old aren't this proud of being 13... :D

[chosenangelx]

im 12

[mideivalmenace]

Hay I'm 13 too I think the LED cube is so cool and I discovered that just a 9 volt battery works fine but I can't decide what color LED to use.

[kdude63]

I agree... I am 13 too and I am not really that proud of being 13, I would rather be 16 and have a car and job. :D But I wouldn't say that I am perfectly normal either. lol

[Sponzyparadox]

Never underestimate the power of a 13 year old. And being normal is so boring. YEAH odd geeks for the win!

[nomooremr.niceguy]

HAHA! Yeah. I suppose you're right about that. I have a 13 year old brother. He's smart, and resourceful, but he's not as into this type of stuff. So I know what you're saying. And yes, it's tough to believe that all this came from the mention of one idea. But it means that people are thinking. And that's good. That's what makes technological advances (and good conversation).

[Sponzyparadox]

True very true though the best way to design and build stuff is to talk about it and then take the best ideas. THough if you fill the bulb with silicone yu will make it harder to break. And there are bulbs made out of plexi for outdoor use try those. IDK And well you met the wanna be new yorkers. We don't know what to do with ourselfves if we can't argue with eachother. Yankees v Mets Jets v Giants the list goes on and on, Upstate v Downstate is the biggest though.

[nomooremr.niceguy]

I'm sure I did meet the wanna be's. I went to NYC, and their pride was more in what was in New York than New York itself (But it may have simply been living in the crowded city that dampened their pride of state). And the plexi bulbs are a good idea. Though I've already tried filling ornaments with silicone. It doesn't dry. It would take years. So try hot glue. Though my dilemma is fitting the battery through the small hole, and positioning the LED in the center. Positioning the LED isn't so tough if you simply fill the bulb half way before placing it. But let me know if you figure out a way to get a battery in the ornament without cutting a hole too large.

[Tommyhzy]

Now THAT'S what humans are meant to do, think, think, think, idea, idea, idea, conversation, innovation! I never had such a heated friendly conversation in a Lonnnnnnnnggg time. It's nice to have other people to talk to.

[nomooremr.niceguy]

I know what you mean. There is no one our age in this area, much less with our interests. Unfortunately our type is few and far between, and too often they are unsavory. But innovators are the builders of tomorrow. So Texans are known for their pride, I've met enough Canadians to know of their pride, and we now have a New Yorker testifying of their pride. Argentineans are also prideful. And we have smaller factions (innovators, Hams, cyclists, etc.) that are prideful. Is there really any practical, and ethical way to measure a persons pride?

[Tommyhzy]

For some reason, I just can't stop thinking about the Lion from The Wizard Of Oz. Or was that bravery?

[Evidenceremoved]

So many people have replied!

[Tommyhzy]

 You do realize that this comment chain continues for a LOT longer, right?   (:

[Evidenceremoved]

Look how squashed up the replies are!

[nomooremr.niceguy]

Yes. He had trouble with bravery. But close enough.

[Sponzyparadox]

how did the lion get into this discussion? lol

[Tommyhzy]

Well, once upon a time, in a faraway time, when all the little DIYers and Instructablers (?) were frolicking in the gleeful meadows of the LEDs, there was a ninj4boy00 who decided to state a very daring resolution. He was going to build a spherical LED "Cube"! So a Tommyhzy came and got curious, as this type of idea was seldom heard of. So they got into a very heated but polite conversation, exchanging knowledge all about the ridiculously complicated world. nomooremr.niceguy and Sponzyparadox soon joined the discussion and kind of morphed it into a philosophical, intellectual talk. So then began the "arguments" about pride, from Texans to Canadians, New Yorkers to 13 year olds, all the while still remaining on the firm ground of related conversation, never straying too far from the base topic, the topic pichu1994 started, which was the topic of how much the materials would cost . Soon, the discussion turned a bit, with idea-to-text-to-world-to-media-to-film connections. And then a curious little child named Sponzyparadox came and asked about how that idea-to-text-to-world-to-media-to-film connection was made. So the eternal storyteller came and started the tale. From then on, the knowledge of how the lion made its way into the conversation was known far and wide, to the North, South, East, and West. As the people gained this knowledge, the townsmen rejoiced, and they all lived happily ever after. (Wow that actually took me 21 minutes and I went through 3 drafts)

[Gmechanic]

Patent your cube, and slap that onto a packaging label, mass produce/market, and there ya go -instant billionaire. ;)

[Sponzyparadox]

Tommy that was epic haha. Yeah I suppose we must have our ADD moments. I mean who else would look at a cd case and see glowing sphere thingy?

[nomooremr.niceguy]

HAHA! Nice. So what should we throw into the mix next?

[Sponzyparadox]

Ohh cookie mix? lol Yeah man I love convos like this though

[nomooremr.niceguy]

Don't we all? What type of cookie mix? I say I like Blue Bell chocolate chip cookie dough ice cream (back to my Texas pride again :D ).

[Tommyhzy]

OH I still remember one of these comment pyramids on one of the duct tape instructables... That was the most epic comment pyramid ever, I had to scroll forever just to get to the reply button to make the comment pyramid more epic... Anyways, now the whole pyramid is deleted, and it's a bittersweet feeling because even though your email isn't filled with 50 comments a day from people adding to the pyramid, the whole collection is gone and I actually wrote about 3 of those types of "long fairy tale stories" into that pyramid... Ahhh good times, that was back in February though. )':

[nomooremr.niceguy]

I'm not so good at writing fairy tales unless they end in total disaster(whether it be the reader or the characters put in total disaster). I think that's for people with good dreams. Mine are always filled with people getting hurt, sick, or on their death bed, and I have to go get help. Inevitably I just happen to jump (and yes it's intentional)off a 50 story high rise building or a cliff or something trying to get to help faster, and I never get hurt (that part is pretty cool). But I never reach help. It's weird. Oh well.

[Sponzyparadox]

Comment pyrmids for the win! And umm Mr Nice guy wtf lol that is really off topic haha. But ADD for ever! Oh pretty birdy

[nomooremr.niceguy]

And the lion thing wasn't off topic?

[Tommyhzy]

O....k...

[nomooremr.niceguy]

Yeah. I'm A.D.D. oh well. I've had worse. I'll forgive myself later.

[Sponzyparadox]

After you play with the kitty? LOL my add just aced me a test so I am like SCORE!!!

[nomooremr.niceguy]

What happened to our pyramid anyway? I've been busy lately. But oh well. no excuses. Just results.

[nomooremr.niceguy]

HAHA! Nice. Yes after I play with the kitty. By play I mean attach the kitty to a Van De Graph generator until it's hair stands on end, let it loose and then stick it to the ceiling. J/K. Has anyone seen the video where the kitty gets stuck on the ball swinging from the fan and then flung into the wall? What test did you ace? That is pretty sweet. Don't you love A.D.D?

[Sponzyparadox]

I aced my History Exam because ADD like I remember stuff and stuff, haha. Yeah tesla kitty!!!!!!!!!!!!!!!!!!!!!! Does it bring down buildings to? ADD rocks haha It saves my life when I am driving. I am like oh pretty tree, pretty birdy CAR!!!!!!!!!!!! LMAO

[Tommyhzy]

Car you say? That reminds me of then the egg tart went into the speaker cable and it generated a binary calendar that only writes in rhyming headsets!

[Sponzyparadox]

Made of plasma speakers and funny stuff IDK haha

[Sponzyparadox]

Which only work if you are sitting on sheepskin seatcovers

[nomooremr.niceguy]

While eating jello on the eiffel tower falling into the moon.

[Sponzyparadox]

Nah how about edison edibles?

[nomooremr.niceguy]

Nice!

[Sponzyparadox]

And lag bolt bratwurst and potentiometer salad don't forget the lube oil martini

[nomooremr.niceguy]

I must say ya'll have me beat. But maybe if we put our minds together we could start a restaurant. Call it Tesla's Board and Fry.

[Evidenceremoved]

Where the chefs cook food on tesla coils, and instead of wearing chef's hats, they wear spartain helmets!

[Sponzyparadox]

Yeah sure sounds like fun lol at least then it will be easier to reply to comments haha. How do we start a group?

[nomooremr.niceguy]

I'm still working on that. If you figure something out, let me know. I have limited time for this today, so I won't be making much headway. Sorry. But if I coupled the acceleron generator to the wire coil, would that put humpty dumpty together again? Or would it just make the cow jump over the moon?

[Sponzyparadox]

Umm yeah or something haha that would be priceless yeah man boredgeek.com or something. iNSTRUCTABLESREVAMPED,com or yeah haha

[nomooremr.niceguy]

Come on dude! we can do it! We'll be rich in no time (Lofty goals are better than no goals, right?) ! Just kidding. But we cn create a group within Instructables if ya'll would like.

[Sponzyparadox]

Yeah dude that blonde is hot, but seriously I am wondering if the led cube will aid her IQ score if we put it behind her headlights. (Score back on topic ish! yeah) LOL prety girl in mind ADD go bye bye yeah . p.s. I could not see your pose to I replied ot this one yeah

[nomooremr.niceguy]

Really? You heard? Well I didn't. Just kidding. I'm actually a pineapple... I'm blonde on the inside. Which goes really well with my A.D.D. and color blindness/deficit.

[Tommyhzy]

And tickling a bar of Fermium that smells like the North Carolina Sewer Life Form when it melts crayons using its laser cutting yodel machine...

[nomooremr.niceguy]

If it cut's lasers with a yodel machine, would I be able to hyper sleep in a moon walk while dreaming of shnorkell blasts eating lima beans in Peru?

[Sponzyparadox]

MMM Jello does it have marshmallows in it? I think it own't work though the skin wants it's sheep back. DOGGY!!!!!!!!!!

[nomooremr.niceguy]

Haha! Still poking fun at the A.D.D. kid huh? Me too. Have you heard about the blonde that got into college?

[Tommyhzy]

I can't read teh comments anymore, They're breaking the white space! They're hiding behind the "Guides" window! Oh no! Run for the Hills! The mountains! The cliffs! Rub that butter on my man mounds! OMGeh! O_O Add reminds me of the time when I stuffed 4 elephants in a mini.

[nomooremr.niceguy]

We should start a group or a forum or something.

[Tommyhzy]

Group Forums make me hungry for some waffle-coated Printed Circuit Boards with a layer of foam board frosting...

[nomooremr.niceguy]

Pass the tinning flux!

[Tommyhzy]

I'd like mine with extra Plexiglas shards, please!

[nomooremr.niceguy]

I only take 22 gauge enameled wire noodles in my spaghetti de trouble. And I'd like a side of lug nut casserole with a touch of silver bearing solder.

[Tommyhzy]

Hey guys keep the comment pyramid alive! (: Don't worry I forgot about it too if not for my bookmark to this site (: Oh and make mine with extra rosin core solder, sprinkled right on top of the PCB cake.

[Tommyhzy]

Psshhhh, lug nut casserole is no match for wire burritos with silicone sealant sauce. That stuff's even better than sheet metal burgers <> LED slices! (Yes, I know what you're thinking, LED slices are OMG-worthy!)

[Phade]

This pyramid is stretching the screen xD

[kdude63]

lol! that is epic!

[Evidenceremoved]

hooray for the comment pyramid of eternal epicness!
Is epicness a word?

[CootaCoo]

Is there any way to change the battery when it dies, or do you have to make a new one?

[Jodex]

You could just crack open one side. And leave it little bit weaker when assembling. Or add an mini switch so you don't have to change the batteries quite soon.

[meso222]

 make it so the battery clips into place instead of soldering it

[TarzanJr]

WHAT METAL DID YOU USE?

[Kryptonite]

Looks like tin to me, it'd work.

[dash-attack]

about the Resistors would a 100 ohm 1/4 watt Resistor work? and is there a picture of what they look like?

[dash-attack]

and is a 10mm led good or what size?

[Kryptonite]

a 10mm is fine, it's just a larger version of your average LED. 100 ohm 1/4 watt resistor is exactly what you want, and they look like the picture below. Just go to an electronics store and ask the guy at the counter.

[jakesllama]

it doesnt really matter if you correct the size of the led with the battery and the resister

[cama900]

How much power is a "high powered" LED anyway?    and is the battery just a watch battery?

[Kryptonite]

About $2, yes the battery is a 3v watch battery, and the sheet metal can be bought at places like Herzog Steel, or Metal Mart. If you go to high school then ask your tech / metal teacher to give you some tin sheet metal.

[cama900]

Where do you get thin sheet metal?

[bmesch2k]

with the momentary switches, does it stay on and stay off when you press it like a normal push button, and if possible what exact kind is that switch in the pic

[skinnykidjr]

yess

[DesChamos]

A momentary switch would only be on when you are holding the button down (for the moment). Toggle switches (the kind that stay on and stay off) are just as common. Your choice really.

[LaxMonkey]

instead of using one 3 volt battery could you use two 1.5 volt batteries. I only have 1.5 volts.

[Beard of Zeus!]

yes, I did

[muse11]

I'm sorry but i'm not very smart with this kinda stuff, but what would be considered a high powered LED?

[thebeatjackson]

I assume he means an ultra bright LED or something, but I'm not sure.

[BabyFaceAssassin]

What is a sharpie? is it a Stanley Knife, or that brand of pen?

[chosenangelx]

black ( or not ) m,arker

[Cybot Rules]

The permanent pen he uses. They are great! Advice: When u dont know something google it! :P Jk

[tombuss2000]

It looks like pandora's box. I love it

[Majafero]

where do you get everything??? could someone reply fast (an actual list for EVERYTHING)

[bladebaka]

Ever heard of a store called EPO Electronics and Computers? perfect place. spend like 4 hours in there just looking at the lot-bought items, and about an hour looking at everything else! they seriously have everything. If you plan on making a "portable" game system using the instructable, its perfect for it.

[yogadude]

I want a blue one. Does anyone want to make one for me? I'll pay good. email me?[e-mail]

[smlkurby]

How much would you pay ?

=]

[rensje]

anything usable instead of plexiglass?? thanks in advance

[chosenangelx]

cd case

[S4mmy]

I found thick acetate sheets that work perfectly! Try them!

[S4mmy]

That's exactly what i want to know...

[Mongo Of Fire]

where do you get plexiglass?

[chosenangelx]

home depot if u live in us or canada

[Majafero]

where do you get everything if you live in austalia anybody??? pretty sure we dont have walmart or lowes here

[finnydog]

just go to a local hardware store like bunnings. i used to live in australia

[Warlrosity]

I know. We are getting CostCo though

[Tommyhzy]

Australia: I'm pretty sure plexiglass is called "Perspex" there, but call it "Acrylic sheet", that's the official name and acceptable worldwide.

[Majafero]

australia sorry

[Mongo Of Fire]

how should I know? Maybe you should have posted that in the "Add Comment" link. I'm actually searching for answers on where to get plexiglass. not questions about places that I've never been to before.

[IM INVISIBLE]

You can buy a pre-made box at the dollar store, it is about 2x2x2 inches with a removable lid. It comes with a metal brainteaser thing.

[Graveyard_Disciple]

so the higher the resistor the lower the light projected? i have two 3.2 forward voltage with 3000mcd brightness. and i want to hook it to a usb which produces 5v or so, what would be the way to hook up, i may make a 6x6 cube with more led any ideas tks

[TechNerd1012]

also, could you use 2 LEDs with one resistor, and make it extra bright?

[pyroten]

you'd have to wire it in parallel with a resistor to each of the LEDs

[TechNerd1012]

what do you consider to be high-voltage LEDs?

[skatesurfdelmar]

could u make this a usb memory stick? it could replace the battery and light up when u stuck it in a computer... culd sombody make an instructable on how to?

[ephrice]

U can make an usb stick but it take smaller measuments on the plexiglass. Are you could take the inside of the an USB stick and pour Resin into a a small box mold. Then place the USB into that while it set up. Be sure to use plastic wrap for a liner or it may stick to the box. This also gives the final project a more textured look.

[Lacurazz]

what exactly would be a 'high powered LED'?

[ducktapedude]

hey where do you get this stuff like a hardware store i want to make this so badly and impress my friends but have no idea how much it will cost or where to get this stuff

[rlindstrom]

the best place to get the led's the switch,battery ect. would be radioshack. i have no clue how much this stuff will cost. you would have to price it out.

[Lacurazz]

The most expensive thing would be the battery which should be about 5-6 dollars with the LED being about 2-3 dollars

[oldanvilyoungsmith]

Ebay!!

[strouslot]

Hardware store. They have it all.

[vodo]

can you use usb insted of a batt?

[get to da parakeet]

i used a motion sensor instead of the switch :|

[alzrc_13j]

hi everybody im new here.i really like doing things like this too and have a lot of questions... resistors are needed right?but will it be dependent upon the value of the LED?what would be the most ideal value of resistor shall i place for most Simple LED ckts...heheheheh sorry i have too many questions...tnx

[Dr.Bill]

First you take a meter that can measure voltage drop across a diode. Generally you will find about 1.2v drop. These are good for low voltages-ie; 1v., 3v, 6 may be pushing it. if you want to use more volts you should use a 47 ohm resistor soldered to one or the other diode leads. then your good. Yellow violet black on the color bands on the resistor.

[Herminator]

Im a noob in this electrical stuff but what's the circuit for this? any pics, diagram? thx

[Herminator]

oh yer and do i really need the resistor? reply fast please

[Tommyhzy]

Yes, you do need the resistor. Or you'll end up with a burnt out LED , a wasted sheet of plexiglass, glued-up switches, wires and batteries, and 2 hours of your life gone. A resistor costs about 2 cents if you buy bulk, I reccomend it because it's like super-cheap insurance.

[R0B0_Ninja]

You need it. period. he wouldn't write it of you didn't.

[-insertnamehere-]

all it is is just an LED touched to both sides of a 1.5volt battery. and no, you do not NEED the resistor.

[garrett10]

Lets say you WANTED to use the resistor. what would you do with it and would it make it work any better?

[geeklord]

Oooohh, speedy reply :D You would connect the resistor in series with the LED, and it would make it a lot dimmer...

[potato wings]

where do I get plexiglass thin metal push button switch resistor a high powered LED and does anyone Know how much a soldering Iron is????????? Thanks For The Help. Potato Wings

[pyrotecnick]

try maplins or radio shack

[ste5442]

Digi-key, Farnell, RS etc are good for components or if you can handle the delivery times you could use ebay - there are loads of cheap 'lucky bags' of components being sold on ebay and thee vast majority of them are full of small switches, LEDs and resistors.

PCBPolice

[balisticjoe]

very simple. 1. Lowes or home depot 2. you can easily use an aluminum project case from radio shack 3. push button switches are available in radio shack 4. resistors are also available there 5. again radio shack 6. at radio shack-a place you better be familiar with if you wish to do most thing on instructables since its very simple to get everything-one is available for under $10 7. (I left this out due to the "be nice policy")

[brandonssk]

Soldering Irons are About 5 or so Dollars at Walmar in the automotives Secion.

[ledmax]

what sort of LED do i need, there are all different color ones and is it OK to use any

[knexcthulu]

not realy some will work better then others but some will lower in brightness then others and some just whont work.

[timntek]

Pretty much. I personally think you don't need to have it too bright unless you want to be very outragiuos.

[knexxpro]

can i get a LED at a dollar store ?
please reply FAST

knexxpro

[airsoftjunkie132]

possibly but you would probably have to rip it out of something there

[ArvindTheNinja]

and if u choose to do that it wont be bright enough.

[PYROMANIA122]

Can you use crafting resin? or does it have to be hot glue? And if it does how much gue do u have to use?

[jackblack]

arsome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[knex maddo]

awesome you mean

[superquack11]

yeah... "arsome"

[pyromacer]

does the amp rating on the switch matter

[AlexTheGreat]

not with this low of amperage.

[SMStephMars1]

how long would the light last? is there a way to replace the battery if you have to?

[REA]

what you could do is make one side easy to pry off without messing the rest up.

[duck-lemon]

yes and it's simple; just pry off bottom, i've actually got a whole lot of improvements to answer peoples problems with this but i get so annoyed having to post over-and over AGAIN!

[cksmith411]

The package of resisters say 180 ohm, but you mention using 100. Is that what you used or did you just have these 180's laying around to include with the picture? What did you use to seal up the plexiglass sides with? i was thiniking of using Aquarium sealent. Since I want to make a design on the inside I think it would work better, but since you have already made them, what is your thoughts?

[AlexTheGreat]

I didn't even notice I was using 180 ohm resistors, thats why it's not as bright as it should be. I used hot glue

[xwx]

This is great I'm going to try to make one of these this weekend with my dad!

[Mr.Clodex]

Prity Nice, keep it up , i am going to try yo make and Weighted Companion Cube from Orange Box.
