I still think that the version 1 is really convenient, using the T12 tips: cheap, fast, powerful. It can be grounded and the standby feature can be easily done without any sensor:
I found this very interesting project, I read all the posts as well as the ones for the Unisolder 5.2. This last one is really amazing but too complex and expensive for me, so I would like to understand if it stills makes sense to do this small one today. I plan to use only T12 and maybe the JBC T245 tips. I would like also to get the gerber files (and BOM) of this one, because I don't have the Altium license. Can anyone help me for that?
