Glad to see that they have a genuine 907 Iron Handle in the picture

Hee Hee Just The Handle Lol

Seems a bit overpriced... and I wouldn't be surprised if they just took one of the many open-source iron controllers around. Running the heater on DC shouldn't be a problem, but I think they should at least heatsink the power transistor (even the 936 clones, which cost less than this for the entire transformer, controller, iron, and stand, have a heatsinked triac).

Interesting concept like the 9936, I bet Hakko never thought their irons would be cloned and shanzhai'd so much. Then again, imitation is the sincerest form of flattery...

Fairly ok price for a digital one  But i've seen them around and they can't be trusted for continous use

Interesting. In US you can get one with the case and knob for 34.95, appears to even have the Hakko front panel. It's funny, with the one K blacked out it looks like "HAKD."

Don't they need a power transformer? This listing doesn't show one. Seems like by the time you buy a transformer and iron you might was well spend 80 bucks on an 888.

You need a 10-24V 3A power brick which probably is a modern laptop power brick (HP started it first!)
But i'll say 24V is the best, because the heaters are 24V native, might as well run them that way but it seems like it's a boost converter so i doubt a heatsink is needed.
Plus ya need to get a original type 936 DIN plug handle, it adds up but hey. If you have like a broken original 936 this could be somewhat useful especially if you have a 5mm brick with 24V lying around, and i have seen shitloads of exact clones of the 936 so that DIN connector is just ... nah, that iron is probably a clone in the picture
But heck! You can use it in your car. I won't dismiss the fact that it probably won't filter the output because DC can oxidise heaters in short order
A 24V 2A power brick is cheap as chips i'll tell ya, don't need a "24VAC" tranny like the 936s do and that's a good thing because the original 936s weigh 1.4kg

The schematic you posted is a clone's schematic right? The original hakko uses a TRIAC driver but if it opamps can do the job i'm not complaining

In the video the heatup time is extremely slow... but that might be because he used a 12V supply so the iron is being driven at 1/4 power (or less).

because DC can oxidise heaters in short order

What?

What makes you think its a boost converter? Obviously your browser does not support image or you have problem with the low rez image. A lot of well designed boost converters requires only thick copper tracks of the PCB to dissipate heat, heatsinks are not always required.
Tell me which boost converter work without magnetics except for charged pump based config.

Free hanging heaters that is ...

Didn't see the video so now i'm led to believe it's direct drive ... it's extremely slow the way i see from his video he probably used 12V, i make assumptions all the time looking at specs and silly me forgot there isn't a inductor :\ It took him 4+mins to do what my 936 does in 20secs! (Oddly i have the fast-heating variant too)
