Picture of The Best Led Project Ever!
I find this project hard to categorize.
It's a combination of my ideas with ideas I got from Instructables and the internet. https://www.youtube.com/watch?v=1LaVV8uWhjg&feature=youtube_gdata_player

Step 1: Tools.

Picture of Tools.
A dremel or similar rotary tool with a good selection of accessories is money well spent. It isn't great at anything but is good enough for almost anything.
An electric drill of any kind with a good
selection of drill bits is also a great buy.
A "third hand" isn't necessary but will prove to be invaluable when soldering small components.
Buy a good soldering iron. A decent pencil tip "Weller" is under $30. and will do a good job.
Get a good quality set of wire strippers.
Get a pair of needle nose pliers and a couple pairs of mini wire cutters/nippers.
Get a solder sucker.
Get a good variety of screwdrivers
You also need a hot glue gun.
An inexpensive multi- meter is a good investment.
Get a few "olfa" style knives and a hobby knife set.

i have made this its great and thank you......... for the project. now i want to use 230v 5w color bulbs instead of the LED used here can you help me?

I realize this instructable is almost a year old at the time I'm writing this, but I think it would be great if you build some sort of case for this, maybe a wooden box that the light bulb tree was coming out of or that it looked like it was screwed into.

Not a bad idea, If I were to build another one, I would still want the Circuit board showing on top of the box. The enamel wire was meant to look like tree roots growing into an electronic circuit-board.

I did notice that after I made my comment, which I agree is an important part of the aesthetic. To change my original thought a bit, what if the bulb tree and roots penetrated a wooden layer with holes drilled into it for each of the root parts. I guess maybe I would be interested in seeing the look if some of the electronics were mysteriously hidden. Although I can certainly see the appeal of this electrical organic beast. Very cool project though!

On the schematic I see three resistors total. 1 4.7k and 2 1k's one 1k located after pot and the other 1k located on the ground for the leds. where is the third 1k?

Ahhhh, sorry. I made this instructable with my phone and had quite a bit of difficulty getting it to work. There are only 3 resistors and my B.O.M. contains a typo. In fact the instructable contains a few typos but I got frustrated when the upload failed 6 times. Sorry for the confusion.

Two questions. Are quarter watt resistors good as far as power dissipation? The BOM says to buy 3 1k resistors. Where is the third?
Homepwner (author)  terwin12 years ago
I used a 9v source and 1/4 watt resistors are fine for the minimal current draw. I used a circuit schematic I found online and it called for three. One goes inline with the pot. The other two were for the 555 timer charge and discharge rate of the timing capacitor. If this doesn't help, let me know....:)

It does. I was curious whether material made a difference and whether voltage was a factor. After more reading I figured it out. Thank you
Homepwner (author)  terwin12 years ago
No problem! Feel free to ask questions. If I don't know the answer (very likely) I'll do some searching...it helps me learn too.

Is there anyway that you would have a part number or more specific description of the caps. it would be much appreciated.
Homepwner (author)  terwin12 years ago
Hi, there are 3 capacitors in the circuit. One is an electrolytic capacitor 10 microfarad. 43 volts.the symbol is uf. The other 2 are ceramic disc style. Used mylar just because it's what I had. They are marked 104
10+ 4 zeros. 100000 pico farads.
Electrolytic capacitors have positive and negative leads. Ceramic disc can be connected either way.... I hope this helps.
Here's a similar thingy I built a few years ago. Mine was a "solar chime". I have parts to make another one, but haven't done it yet.

That is truly beautiful! And the "solar chime" concept is new to me.
If you have a video of the sounds it makes I'd love to see/hear it.
We seem to have had the same vision on the "look" of our projects.
Nice work!

Hi, here is my take on this project:
I didn't have a globe to use, so I used the dome from a cracked glass garden light. It would have been nice if it wasn't cracked, but it turned out okay.
I wrapped the white insulated wire with the silver un-insulated wire instead of using enameled wire.
I also used an Arduino pro mini to drive the LEDs.

Very cool. I'm sure the cracked glass adds a nice effect in the dark.
I have zero experience with arduino or any microcontrollers/programming. I am interested, but I wouldn't know where to start.
Any advice?

Here is mine led light bulb following the rhythm of music or speech picked-up by a small microphone,the projects is very cool.Check it:)

I uploaded a video of it in the dark and fixed the private link problem (I hope) cheers!
Your youtube link is private.
Sorry. I'll try to fix that.
