How to make a soldering iron from pic related?
24V 2A DC output, and also has a voltage adjuster
>>972141
step 1: take apart toaster
step 2: put heating element from positive to negative
>>972143
>take apart
The supply has screw terminals right there already
>>972146
... yes, but you need to take the heating element out of the toaster
>>972152
it may have short circuit protection
it also has a green LED, when I plug in the psu, the led turns on, if i reduce the voltage output, it starts blinking, slower, as the adjuster is lowered.
When it's shorted, the led goes off.

I have no spare toaster. Buying nichrome wire might help? (shame on me, recently threw away a hair dryer)

According to ebay it has
Protection: Shortage Protection, Overload Protection, Over Voltage Protection
>>972141
You buy a soldering iron for $5 off ebay, or you just heat up a nail on the end of a stick.

>Shortage Protection
would prevent exactly what you're trying to do

...(probably)

they look like pretty unsafe and have no money for the $100+ stations

24v 2a is barely anything. Max is 48 watts. Even if you could get it working it'd be a little disappointing for soldering. You should also try using pencil lead instead of toaster filament.
This is 5v 30a 150 watts.

Look for a 936 soldering station.
Around 30 bux or 20 quid
Also grab a thermocouple to calibrate the station.

>unsafe
It's a hot pointy thing, of course it's unsafe.

>24v 2a is barely anything
That is the power usage of these. Been using one for over 20 years.

> 24v 2a is barely anything. Max is 48 watts.
A 15W iron is adequate for soldering most components to a PCB.
Although a proper iron will probably be a bit more efficient than a DIY one.

Remove shortage protection.
OP here
>>972436
Bit scared to mess with the circuit as it may fuck up the psu

I did my youtube research earlier, and found the pencil lead method aswell, but abandoned it as soon as my fresly bought pencil had less than 1/3 pencil lead size of the pencil and shattered easily. So today I bought 0.7mm pencil leads and a thick pencil which had pretty thick and long graphite.
The positive side of the 0.7mm kept shatterring and emitted bright light on contact. Using the thicker lead helped the shatterring and both glow red. As it started fully glowing red hot, it shorted and stopped, and started the process all over again.
Still need isolation to make it usable for daily usage

I've never had luck with DIY low watt irons that were not using graphite. And, it is really nice to use a foot pedal with the graphite ones since you don't need to wait for them to heat up. Instant on and instant off. No problems with burning things when you do something stupid, or someone else does something stupid around your iron.

You need a heating wire which has at the length you require a bit more than 12Ohm resistance.
Calculate what you need, buy wire.
