My Hot Air Pencil in Rs 300 for smd




ARM9 soldering problem is solved.. i made the hot air pencil.
See pics and details are ...
Parts needed :
1 cheap soldering pipe shaped ,coil heater type:140/- like this http://www.hvwtech.com/products/206/44100_PV.jpg
1acqurium pump + air pipe :130/-
6 inch pneumatic tubing :30/- like this http://ecx.images-amazon.com/images/...500_AA280_.jpg
(my innovation
it withstands approx 100deg, at the coupling end the temp does not go v high).
Super glue , paper etc..
How to :
1.rip apart soldering iron, remove metal tip.
2.Leaving the front hole (where metal tip was there) cover the other holes with 2 layer of paper
put duct tape to make the paper hold.This is to prevent air leak.
3. connect air pipe to the 6" pneumatic tubing
seal the joint with superglue,put the other end of the tubing to soldering iron metal pipe. with paper as insulator.

4. Close the soldering handle with pipe and wires
mine is taped to hold together."Be careful not to short mains wires".My iron had fully insulated mains wires.
5. Plug in the pump and iron together.
wait 20 -30 seconds... check the temperature by burning some paper. Then try on solder.
