JBC-mini - a low cost T245 handle controller

<< < (9/12) > >>

I have no idea to be honest. My best guess is that connections between the cartridge and the handpiece have low ohmic resistance,  but rather small cross section and therefore thermal coupling is not very good.

On the other hand JBC really knows metallurgy. On one occasion by a mistake in the software I got the tip to white-hot-and-glowing state,  and after it has cooled down it still worked ok...

I looked a little more at the handpiece anatomy and noticed that it's the metal ring at the end of the piece (which is not supposed to get hot) that acts as a contact for the sleep mode. The cartridge changing tool is wired to another pin, but doesn't get hot because the tip isn't heated anymore.

Didgitalpunk:
Very cool project! can't wait to see it finished.
Btw, when you have time, would you mind sharing the PCB layout files and parts list? schematics? I'm quite interested to do one myself and I think quite a couple folks here are as well :)

timofonic:
Any news about it? JBC are nice, buy their stations are very expensive.

They are from my country, Spain. I'm happy there's something good here...

poorchava:
Heh,  still no time to finish the project. I'm working on it hour or two a week, but unfortunately I can't devote more time to it.

But no fear,  the project is definitely not dead.
