Handy ring light for extra hands

This is probably one of the most used tools in my workshop, the "extra hands".
It is the ultimate tool for soldering and prying in the very small range. But over time I found that I do not have enough light on my work when using this tool. Actually all the benefits you would expect from having a magnifying glass for easy reach are over shadowed by the shadow cast by the rim.
And honestly I haven't managed to position my desk lamp in such a way that I was able to conveniently light my tiny work.
So I decided it is time for some upgrades.

As usual you will find all G-code and other  files included so you can reproduce this easy on your own CNC machine

Step 1: Materials & equipment

Materials
PCB prototype board unstructured (rs-components)
Resin cored solder
PCB LED's warm white 40pcs (old LED tube light)
Old 12V DC transformer (anything with more then 3W will do fine)
E-wire (some scraps)
Glue sticks
Double sided tape (carpet tape)
Some Acrylic sheet scraps

Equipment
CNC mill + computer
45deg engraving too or 0.5mm flat end mill
2mm centercutting flat end mill
Soldering iron
Tweezers (forceps)
Some crocodile clamps
Hot melt gun

There are "angel eye" LED boards available on eBay and Deal Extreme that are basically a round PCB with LEDs on it if you dont have the equipment to make a PCB. However getting decent size information from the sellers can be a bit of a hassle sometimes.

that does take all the tinker fun out but fair enough, thanks for the tip

If those are anything like the surface mount LEDs I've been using, they are a huge score. I paid like $2 a piece for mine.

Wauw, well maybe I cheat a little bit because im import/develop tube lights. On average I pay about 40 euro's for 500pcs smd led of this type, maybe a bit less even. As a private person you should not pay more then double that I guess (local sellers need to eat too). So 20 cents each sounds fair to me.

On top of that I used high efficiency LED's with a light output of more then 100lumen/Watt giving this tiny ring I build here about the same light output as a good 50W halogen spot.

I used google sketchup to make the PCB design.

sorry im new in that~is that normal sketchup or google sketchup Pro?
i already download it but dunno how to use = =

[cold_steel]

Sketch up pro in my case. I think normal sketch up does allow for exports in 2D.
Just check file>export>2D. For PCBs this would do, for sure you need pro for 3d exports.
Hope this helps

may i know what is the PCB drawing software tat u used?
