Awesome led cube

Step 3 Lighting

Solder together the switch, resistor, and the led.
Duct tape the two wires that remain to the battery.
Hot glue the assembly to the inside of the cube with the button in the hole.

this may help, its from a different led cube instructable

[elga]

thank

[TCInc]

has anyone actually passed this step. Can someone tell me which order you solder the LED, resistor, and switch without only showing a diagram?

[absolutekold]

it dosen't really matter. a diode is uni directional... as long is it, the switch, the resistor and the battery make a big loop if laid flat (series circuit) you should be good. if when you close the switch (turn it on) the led don't light up (provided the led and battery are good) switch what wire goes to the positive and negative plates on the battery. the resistor sets the current limit through the whole circuit the diode having virtually no resistance would over current (blow up) in absence of something limiting it. in fact if you didn't care about turning it off you could leave off the switch altogether.

first the switch , then the resistor and last the LED.

[toxicwolf]

hay whats that guys name in your pic i know he is from code geasse
isnt his geasse mind reading he got his geasse from C2 right

[TCInc]

Yeah he can listen to peoples' thoughts and C.C (or C2) gave him his geass at a young age. His name's Mao

[toxicwolf]

ya he is my second favorite character
no offense to u
my favorite is C2
my girl friend dresses like C2 or some times even Misamisa from deathnote (you know Light's girl friend)
my favorite character from deathnote is Ryuke

[TCInc]

Yeah, C.C is pretty cool. I havent seen DeathNote in a while so i forgot who's my fave

[toxicwolf]

well that sucks

an advanced concept for the switch is to glue several pieces of plexiglass together slightly larger than a chosen shape. then drill or cut a shape into them (sometimes easier if cut before glue depending on shape like just a round hole would be better glued than drilled) and attach a switch to the bottom so that the button sticks into the cavity (one of the press close press open kind). wrap the "extension" in wire to make it an electromagnet and connect the wire in line between the switch and the resistor. now use a steel blank in the aforementioned shape that is the size of the whole to trip the switch. this if done properly gives a neat effect the cube lights up if you insert the metal "key" but it does not fall out when lit. pressing on it again (turning off the switch) turns the light off and releases the "key". putting a capacitor (the size will vary the amount of fade) across the leads of the led would give a fade effect when turning on and off. the pdf is a pic the site was giving me crap about uploading a open office drawing.

 Can you please give a diagram of where to solder what?

[idlehands987]

do i have to use a watch battery? can i use ordinary battery or camera battery?

[kevinster]

for the plexiglass i just got the guy at ace or lowes or home depot to cut it for me

[jermspool]

theres an easier way to put the LED in the box. look up the led throwies instructable. no resistor or pushbutton

[jakesllama]

i thnk a reed switch would be a good idea you just need it near a magnet

[the_don125]

While that method is indeed easier, it will severely hurt the battery life, first because it prevents the LED from ever turning off, and second because a high current is going to be flowing through the LED for its entire lifespan, draining the battery (which cannot be changed) very rapidly.

[utahskiboy33]

what does the resistor do?

[dumle29]

it reduces the power going to the LED so it doesn't burn out

[clinky]

im new to the eletricle stuff can u plz be more spasific i have evry theng i need pppppppppllllllllllllllllllllllzzzzzzzzzzzzzzzz

[dash-attack]

hey what do you need help with i think i can help

[Spiderdog3000]

How do you solder the resistor, the led, and the button together?

[dunnos]

uhm.... battery+>resistor>led>battery- did that help?

[Spiderdog3000]

A little bit. So the led attaches to the resistor. What about the button?

[Fridge Gnome]

/\ <the light
| | <wire
switch > ^{| <wire}
| |
0 <power

[h29zf]

where rester go?

[Spiderdog3000]

k thanks. I got it.

[Falconer13]

If you get really creative, you could build a gravity switch and use that instead of a button. Granted, it will only work in one orientation but you could have a completely sealed box. I might put an instructable up for the switch once I figure out how to build one.

[JavaNut13]

you could use a mercury switch..

[dumle29]

or a reed switch

[Spiderdog3000]

Nevermind. I got it. It's working now.

[M4industries]

You can put the button anywhere in the circuit, just make sure that the actual moving part is outside the box.

[Spiderdog3000]

Is it absolutely necessary to solder them together? is there any other way?

[Davidnipp]

just an idea, but it would be really cool to use a reed switch so it would be really easy and cool to light it up. You could pass it around and only you could light it up because you have a magnet somewhere closing the reed switch. *try to give some credit for this idea*

[zeroemission]

you could also diffuse the light by sanding the plexiglass inside & out, before assembly obviously, or lining it with paper or even cotton wadding. you could also just use translucent white plexiglass like they use to make light tables.

[grifmaster93]

umm is there anyway to make it solar powered....so i wouldnt waste on batteries

[TXTCLA55]

Check out my Solar engine ible here...

hey just buy a solor paneled garden light, it already has the switch and LED, you could swap em out. then just stick the solor panel on one of the sides, prolly the top. you will want to drill a second hole.

[TimTheScarecrow]

wow. i think i could take your little instructable and put my own spin on it and try to remake the hellraiser cube. think i could?

[Trottar]

With the wiring of the led, battery and on/off switch, can you put a picture, or diagram on how you made it. Just not 100% sure on the construction, and don't want to waste money in case i overpower the LED. Thanks
