How big would the electrical bill be?
Yeah, 5/6 amps at 12V, not sure how this would translate in 120/220V.
Probably best with using a foot pedal from a sewing machine or synth, PWM.

well, just approach a junkyard and start over.
: )
Car's replacements part shop will also have these, most probably, the one used in the video looks like it originated from there. it looks new or was never used.
but maybe the life could be extended using a 8 bit MCU with PWM, push button + timer and some power mosfet.
A better solution would also be a wood, metal or plastic chuck where it's fixed with the ability to adjust the height.
You need to dial it in anyway according to the recommended heat profile indicated in some datasheets.
I just found out: mouser sells solder paste
"SOLDER PASTE SAC305 CLASS4" from Olimex LTD
https://www.mouser.com/datasheet/2/306/Sn96_5Ag3_0Cu0_5-3223704.pdf (Chinese)
Shelf life: 180?
115€
Looks dangerous, be careful.

As a kid, I used to play in a junkyard. Not too many cars still have the lighter when they end up in the junkyard...
And if you buy from the carparts store, you might as well buy a hairdryer or paintstripper. About the same price. Less DIY, but hey, lasts a lot longer. I just bought a hairdryer from ALDI. Fairly solid, just 10€. Even has a ground sense switch for safety. I bet the lighter from the parts store costs more. At least, over here. We don't have stores like O'Reilly's in the US. Parts stores here are fairly expensive, unless you're a mechanic, than you get a 40% discount. Of course, Alibaba and Amazon also sell these. 5$ on Amazon. One in red with the text "Fire missiles" is a bit more expensive

As a little kid, i played in the rusty old past due car from my aunt, parked next to the house.
I found the cigarette lighter inside and pushed it in, after a while the button returned, i took it out and pressed my finger against the red hot metal.
resulting a painfull spiral print on my finger print.
: )
Do they have ALDI in the USA?

Aren't you supposed to have *air* flow for a hot air station?
Aren't you supposed to have *air* flow for a hot air station?
Yeah, I think technically that should be considered a homebrew IR rework device, not hot air.
If you search "hot air rework station" at Amazon you get an entire page full of choices, starting at $35. Seems like a more than reasonable price to me.
I can't speak to the quality of the $35 rework station, but can it really be worse than a surplus car cigarette lighter with some wires hanging off?

Soooo, the question was how much it would cost in the Electric bill? ? ( really? ;-)
lessee..... from Electric Shop (Junior High) seems like 5 amps @ 12 v= 60 watts. = .06 kilowatt hours.
(Even in California that's 2 cents an hour..... This thread has has used more juice than that.....

I peaked in the datasheet of a recent core intel i5 after hearing some guy on tube speak on fets.
It consumes 145 amps @ a voltage around 1.5 Volts at full power.
(pretty much impossible to run a thing like that on a breadboard and also having 2 x 64 address pins.)
What i meant to say was how 5 amps translates after being processed by a transformer.
If i did the calcs correct it would be like 0,27 amps @ 220V.

yes 5 amps at 12 volts (60 watts) is .27 at 220 volts. -and still 60 watts) -Transformers are very efficient, the loss thru transformer is negligible, -much like the 2 cents per hour that the 60 watts costs ;-)
