  I made a quick measurement to see how linear the iron's temperature sensor is. Since I don't have a thermocouple I used a Pt1000 strapped to the heating element like this:

  So I had one DMM measure the Pt1000's resistance and another one measure the resistance of the iron's sensor. Afterwards I calculated the temperature from the Pt1000's values and came up with this graph:

  just some notes, can probably be moved to components section once finalized

  I might be falling into a pattern...

  For now I just want to collect all the sources in one place. The list is somewhat sorted but hopefully I'll go over this list again and summarize all/most of them and maybe do some more sorting.

  A quick heads up: There are a lot of duplicate links but I wanted to document for myself how/where I found the projects.

  Hakko 907:

  • I already mentioned this one which was featured on the blog - I really like the option of driving two irons and the author makes a good point for the analog dial. He also proposes a mod for better heat conduction between the heating element and the tip.
  • Right now I'm thinking whatever I'll end up building is going to be very close to #Hakko 907 based Soldering Station because it's very straight forward.

  • #Soldering pen by @HP (@banjohat) - also based on the one by [Martin Kumm] linked above, very cool idea of integrating all the controls in the handle, made me think about applying this concept to the 907 iron/handle

  Weller WSP80:

  • http://www.eosystems.ro/index.php/projects/esol - uses MCU's internal PGA
  • #Yet another DIY soldering station by @SUF - expected to have 3 (!) soldering irons and a bunch of other useful features, especially like the ideas to reduce energy consumption
