This idea came from over at PCB heaven (pretty good site, lots of info
PCB Heaven
Its a Temp controlled soldering iron with temp feedback.
Am going to build as my wife won't buy me a $75+ soldering iron
The orginal schematic had some minor errors so I THINK I corrected most if not all.
Appreciate any corrections etc before I etch a PCboard.
Oh yea Maxium has FREE samples of the MAX6675 chip
Thermocouple from Ebay
hopefully build for under $20
The artical has hex etc files.

Already have iron, LCD =$6, PIC = $3 Max6675 FREE SAMPLE
case = old computer power supply
Have sockets, ribbon cable, Triac / opti coupler left over from computer xmas lights
Projected cost to complete (needed parts to purchase) $20 or so.
HOPEFULLY

Have you considered to get a job to pay your own expenses? In few months you could even afford as scope and maybe a frequency analyzer...

Am retired. All my woodworking tools and electronic "lab" are bought and paid for with side jobs over the years.
I never used household $$$ for my hobbies.

Sorry MrDeb

My text failed to convey a friendly attitude. Far from me to make fun of you or anyone else here!!! I wonder what I would do the day I retire (not too far myself, maybe this year).

In my case I had to count every $ quite carefully to buy anything.

For my first multimeter (Simpson with mirrored scale) it took me almost one year to collect the money.

Wish I win some lotto to buy few more things. (Like a Mercedes C 200 to come to my lab...)

If you want to buy some stock - look at FMETF
this is a mining stock that is going to actually start mining in 2011.
Mining for WHAT you ask? COLBALT
only other place COLBALT is mined is Africa.
WHAT is COLBALT used in = Batteries, electric cars etc.
stock is at .93 this morning
Most of the equiptment, machenery etc. are sitting in a wharhouse in Salmon waiting to be installed. The company is presently clearing land etc.
Samples show that the deposit is very rich in colbalt.
