When a project ends, I'm always deeply moved. Especially, when it's successful. This one was. Enjoy the final Photo and the video for soldering. The controls in the vid were made by hand, but the video playback is 8x original speed for entertainment reasons. It shows the soldering of 29 holes. I planned a more interesting soldering, but I ran out of time. There will be a following project, I guess.

Have fun!

Annex:

some source code of the controller, for your amusement:

/*
 * commands:
 * -> move head to the right (X)
 * <-    .. left
 * ^     .. back (Y)
 * v     .. front
 * PgUp  .. lift (Z)
 * PgDwn .. drop
 * +     .. feed solder 
 * -     .. remove solder
 * s     .. enable stepmode (=auto stop after 1/25 sec.)
 * c     .. continuous mode (=permanent drive)
 * esc   .. stop all commands immedeately
 * l     .. enable low speed
 * h     .. enable high speed
 * Y axis has high speed only, because it's slow
