He just wanted to share what he's been working on, doesn't mean he's obligated to give you everything. Don't expect others to do the work for you.
Yep. This sections' description is "Show off your projects or other stuff you are working on." I think some people are confusing the EEVBlog forum with an open-source repository doubled with a free design service.
Some people also don't seem to realize that some of us may not be allowed to completely share a design depending on a number of factors. Just realize that unless we have decided to open-source a design, or put it in the public domain, sharing it without any kind of license is an issue that we don't necessarily want to deal with.
Sorry but if you don't give the firmware the entire post is useless in my opinion.
The schematic for a soldering iron is very simple, anybody can design it in 10 minutes. The difficult part is the PID tuning.
Having actually worked on that as shown, instead of just talking about it randomly, I do think the opposite. PID controllers are textbook stuff. You can find them anywhere. Tuning can be a bit lenghty but it's not hard, and obviously it entirely depends not only on the iron (/cartridges) itself, but also on all the driving electronics, so it's completely linked to the schematic as well.
The schematic is the "hard" part IMO, not that it is really hard per se, but just because we are dealing here with basically undocumented stuff. A few other people have reverse-engineered those JBC cartridges, not all with complete exactness though - so getting it right is the tricky part. Thermocouple sensing is also not trivial, especially here where you have to deal with the heater that is basically in series with the thermocouple.
Its ok if you don't give your schematic or firmware but at last you should give some useful infos, but nothing ... "
I thought you just said above that without the firmware it was useless. Looks like your are already changing your mind a couple sentences later.
I gave minimal info so far, but I think enough to get people who'd be interested to look for more info by themselves (talked about the TBH algorithm, you can find a handful of links about it online, talked about the main ICs I used...)
ps. Even the link that you provided don't work properly (the images are not displayed).
Those are all forum-attached pictures, no reason they wouldn't work. Sometimes they are a bit slow to appear when you want to see the full size though - depends on the server and your connection obviously.
Anyway, parentheses closed. If anyone has specific questions, I'll gladly answer them. I can also post parts of the design that I think would help the most without disclosing the full thing (like how the handle is wired exactly, how the thermocouple sensing is implemented, and the regulation algorithm as pseudocode.
