how to get free electronics out this dead  "Compact fluorescent lamp" there is so many electronics in there 
there is transistors , resistors , audio transformer , capacitors , diodes ... etc.
  
    the target of this cool project is recycling dead  "Compact fluorescent lamp" to get a free electronics to use it in other projects
to make some thing cool out of  "Compact fluorescent lamp" .

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime.
Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.
CFLs radiate a spectral power distribution that is different from that of incandescent lamps. Improved phosphor formulations have improved the perceived colour of the light emitted by CFLs, such that some sources rate the best "soft white" CFLs as subjectively similar in colour to standard incandescent lamps.

My mother doesn't want me to do this because she is worried about the mercury in the lightbulbs. How safe is this to do and is there a any risk of mercury exposure?

as long as the glass doesn't break you should be ok.

If you glass breaks, don't breath in.

i don't think so , but it is safely to do , just open the plastic box and cut the wires ,Done! :D

or you can use a plasma ball to light it up:

cool, great idea and concept, except what do you do with the bulb part

Another quick tip for removing components is the use of a hot air gun, got mine from harbor freight for about $10 and use it all the time.

thanks for the tip

There's not a LOT of mercury in those bulbs, there's a MINISCULE amount of mercury in there, and it's not in metallic from, so clean up of a breakage isn't a major headache, the guidelines quoted say more about the originators desire to cover it's legal posterior than the actual hazard presented. That's not to say that the stuff isn't toxic, but some fairly basic common sense precautions should take care of it. After all people have been dealing with Fluorescent tubes for years without it becoming a major HazMat incident.

Could you rip it appart more quickly, possibly, but it's not inappropriate to take time and reinforce your skills. Keep up the good work, thanks for sharing.

The main question is "What are you going to do with the stuff now you've GOT it?" Keep us posted.

ok , first thanks for comment , second you can make Joule Thief with it and you can use the capacitors in a coil gun

For a small PCB & a few parts your methods are just fine,Mahmoud. You don't need a bunch of equipment & all that "hot air" to have fun & learn something. CHEERS!

OK , thanks for commenting

You need to be VERY careful doing this!!! There is allot of Mercury inside those bulbs, it can be very dangerous!
From the EPA's website:
"Before Cleanup

Have people and pets leave the room.
Air out the room for 5-10 minutes by opening a window or door to the outdoor environment.
Shut off the central forced air heating/air-conditioning system, if you have one.
Collect materials needed to clean up broken bulb:
stiff paper or cardboard;
sticky tape;
damp paper towels or disposable wet wipes (for hard surfaces); and
a glass jar with a metal lid or a sealable plastic bag.


During Cleanup

DO NOT VACUUM. Vacuuming is not recommended unless broken glass remains after all other cleanup steps have been taken. Vacuuming could spread mercury-containing powder or mercury vapor.
Be thorough in collecting broken glass and visible powder.
Place cleanup materials in a sealable container.


After Cleanup

Promptly place all bulb debris and cleanup materials, including vacuum cleaner bags, outdoors in a trash container or protected area until materials can be disposed of. Avoid leaving any bulb fragments or cleanup materials indoors.
Next, check with your local government about disposal requirements in your area, because some localities require fluorescent bulbs (broken or unbroken) be taken to a local recycling center. If there is no such requirement in your area, you can dispose of the materials with your household trash.
If practical, continue to air out the room where the bulb was broken and leave the heating/air conditioning system shut off for several hours."

As you can see, they're DANGEROUS!

OK , first thanks for adding your comment and for the information but we don't need the glass tube and we won't break it we will just hack it and take the PCB to get the electronics

Desoldering parts off printed circuit boards with a soldering iron is a waste of time compared to better methods. Personally I use a solder pot, but others successfully use blowtorches, and other means of heating more than a lead at a time. I'd have that whole board stripped before you got your first part off it.

Remember, parts salvage is not board rework! There are no bonus points awarded for saving the PCB. Getting it done, and removing parts in such a manner that they are still functional are the goals.

i didn't get it right please explain more

OK, this guy isn't very good, but he does it how I do it, so he isn't that bad.

You can rig up a molten solder pool on a barbeque with a dished piece of scrap sheet metal. I saw a video of a fellow in China doing similar. Or if you're not into the open flame effect there are articles on this site about how you can make your own solder pot.

The trick is to melt the solder on all leads at once, then parts pop right off. A soldering iron is great to put parts in, because you can attach one lead at a time, but that is no good for taking parts out!
