The Best Led Project Ever!

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.

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.

Step 2: Major Supplies

Picture of  Major Supplies
1) experimenters board.
2) fine solder
3) enameled wire. (I recycled mine from an old t.v.)
4) jumper wire. ( I bought a breadboarding wire kit ) you can make custom lengths from solid core bell wire.
5) a project box. large enough to accommodate a 9v battery/clip and 2-3 switches.
random stranded wire.

Step 3: Specific B.O.M.

Picture of Specific B.O.M.
Parts and components.
1) 9v battery clip
2) 2x spst mini toggle switches
3) 1x Large dome clear 40watt incandescent bulb.
4) 1x 5mm dome U.V. led
5) 10x smd ultrabright leds
6) 1x 555 timer chip
7) 1x 4017 decade counter chip
8) 3 x1K 1/4 watt resistors
9) 2x 104 ceramic disc capacitors
10) 1x 10 microfarad electrolytic capacitor.o
11) 1x100k linear taper potentiometer
12) 1x 9 volt alkaline battery.
13) 1x 4.7K 1/4 watt resistor
14) Tonnes of patience and the ability to read a schematic .

Step 4: Cut The Bottom Off Of The Lightbulb

Picture of Cut The Bottom Off Of The Lightbulb
Use an abrasive cut off disc to remove the metal bottom of the lightbulb.
Then very gently use the cut off wheel to cut through the part where the bulb sticks out.

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)  terwin18 months 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)  terwin18 months ago
No problem! Feel free to ask questions. If I don't know the answer (very likely) I'll do some 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)  terwin18 months 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.
Homepwner (author)  frankendaddy9 months ago
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:)
Look my youtube video:
very nice work! turned out great

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.
