I liked this idea. Instead of messing on the insides of the hair dryer, I just made an enclosure to focus the entire air to a much smaller point and I added an extra intake fan so that the hair dryer itself does not overheat and now I can desolder using the same hair dryer as heat gun
2:47 Wait if its just because of resistance, why not just leave it how it was & then figure out the math for the resistance you need, & then resodder the wires to the corresponding voltage, or is the only way they use the resistors is through the heat springs?
This is all kinds of wrong! Using less of the heating element does, yes, mean less resistance, but that is not what you want. Less resistance means it will draw more current. Most larger hair dryers like that are already at the limit of how much you can safely draw from a wall outlet. Heck, it's even in the model number of the hair dryer "1875" likely meaning 1875 watts, which would be 15.6 amps at 120 volts. The outlet itself is rated 15 amps unless it's a special 20 amp outlet which would ve denoted by a "t" shaped slot for the neutral contact. Another negative effect of lowering the resistance is it speeds up the fan, which is counter productive to making more heat. Pulling more air faster through the coil cools it more. Real heat guns don't have anywhere near the blowing force of a hair dryer. The REAL way to make a hair dryer a defacto heat gun would ideally be to modify or replace the thermal cut-out (safety thermostat) so as to allow it to reach a higher temperature before it shuts off the heating element, and also, slow the blower with additional resistors, or simply resitrict the airflow into the back of the hair dryer to reduce the amount of air passing through. You could also just bypass the thermal cut-out alltogether, but then you'd have to keep a keen eye out to make sure you don't let the thing get hot enough to melt itself to the point of allowing components to touch that could cause a short-circuit and really become dangerous. Real heat guns have safety features, so just make sure you keep the ones built into your hair dryer and only modify it enough to get the job done without risking serious injury or burning down your house. And remember you're working with enough electrical power to easily kill you; don't attempt this at all if you don't understand electricity, basic physics, and eletrical concepts like Watt's Law and Ohm's law. And before anyone gripes, "If you already know how to do this then why tf are you watching": I was looking to see if someone has a good source for getting ahold of higher rated thermal cut-outs, how to change the thermal cut-out to a higher temp setting, and an elegant, consistent way of slowing the blower or restricting airflow. What I ended up finding was this safety nightmare of a video with a guy who obviusly knows next to NOTHING about how the thing he's trying to modify actually operates, yet has no qualms about becoming a RUclips professor of something he knows very little about, potentially encouraging others to engage in this highly risky "activity". Be safe out there!
The hairdryer intermittently blowing into the microphone at the end was funny. Could you explain it like you would explain it to a slow child. How did you bypass the... fusible link?
I think the hairdryer is giving enough heat. Just funnel the hot air through a smaller nozzle that you can hold. Maybe get better heat/temperature/airflow regulator switches
Hey. Brother. I wasted out 11.46. minutes of my life, to see NOTHING. Next video. Plan it better, focuses on main things. Improve ir camera to SHOW HOW NOT TO SAY HOW. CORDINATE UR IDEAS. BETTER.

take it out? and join the wires together
So powerful! It's blowing the camera everywhere. Yes, how do you make a heat gun from a hair dryer. Still don't know.
this is exactly what I'm looking for,if modification of hair blower would work to convert it as heat gun

Auto heat detect will stop the fan
