I would share the list, but RS does not have this feature. But with those prices there is no point really.
Don't worry. I have no intention to go with that. :)
But generally, it would be really great for the project to have a few links to shopping lists on various parts suppliers like farnell and a few others. Or have the part numbers in the excel sheet.
PS: SZ64 will actually sell me the complete list of parts. So I'm good.
PPS: I was a little surprised that I can not find the bare OLED anywhere. Seems a little excessive to buy a full kit including display driver and then rip the screen out.

Thanks also to JJAnderson. This list will help identify the right components. I can't buy with RS though. The minimal order quantity pushes the BOM price over 300 EUR. For that kind of money, I could go straight to JBC and buy the most expensive option. :)
Not that I expect to pay a whole lot than a professional solder station. Universal is the selling point here for sure.
SZ64 contacted me directly, he will sell me most of the semiconductors and inductors and shunt resistor. That will help a lot.
Does anyone have a board in EU? OSHPark is throwing a error 500 right now...

Ah well, Farnell in Germany is special. Very much not the element14 type hacker friendly establishment. They are stuck in their ways and actively and quite rudely get rid of non-commercial customers.
I was always a happy customer with Farnell UK and I think they were happy with the level of compulsive impulse buys. :)
Anyway, they don't want me and I don't want to beg. Fuck them. :)
I have to spread my BOM a little I suspect. I can for example not find a single coilcraft product ad digikey. Which is a little crazy TBH.
Here is my list so far. Only capacitors, inductors, diodes and a few transistors so far.

Perhaps somebody here in the forum will step forward with a public shopping cart that actually makes sense. :)

I guess it could be better with farnell, but they don't do business with end customers in Germany. :(
I wonder, has anyone built a complete BOM which he could share. At some kind of shop that sells in Europe.
Ideally, I would hope somebody would make a kit. I don't mind soldering this board, but some of the parts are surprisingly exotic and I'm no purchasing expert. (Inductors for example. I think only size and impedance matters, but I'm no expert)

MCU or EEPROM with temperature sensor in the handle is very interesting approach. The TC cold junction is in the iron's handle, so if you read it there, you will get some more accuracy on irons with TC sensor.

Oh dear. I hadn't even considered cold junction devices.
Yea, no kidding those would benefit greatly.
In fact Maxim has a nice 1-Wire thermocouple amp with cold junction compensation and all that jazz. ;)
PTC based devices would not benefit. And I suspect those are the majority of devices?
But I think you have greater goals. One board to rule them all.
And I absolutely love the idea. :)
In the end it's just software. Keep it open and stuff will happen... ;)
PS: Looks like thermocouples are quite common. I guess I jumped to conclusions.

One could even consider saving cal data on a EPROM in the iron.
But yea, its overkill nevertheless. :)

How does it detect each soldering iron? How are adapted?

I was wondering the same. But it turns out that is described on the first page in the feature list.
- resistive instrument identification (upto 625 different instruments can be identified by 2 resistors on the connector)
I had already suspected ID chips and the like. But honestly, resistors are so much more easy. :)
You have to change the plug adapter anyway to be fit. Might as well add two resistors in the process.

Is it Open Hardware? What about putting it at GitHub?[/quote]
Good suggestion. If real collaboration is actually going to happen.
I would love to build one for me. But I would prefer to buy a kit. Or at least the bord.
