  1. There are a lot of different techniques you can find by googling. This situation happened to me once, and I succeded using a technique that surprisingly I cant' find anywhere:

    I put a very small amount of loctite on the top of a flat barrel of a diameter slightly smaller that the tap, and carefully introduce it into the hole until it makes contact with the broken tap. Then I wait 2 min while maintaining the pressure to make sure the two are glued. Then I unscrew gently...voilĂ .

    Problem is you can glue everything together, and then you are screwed, but if you are careful enough, and have a steady hand, it should work.

  2. Boards received! Can't wait to see it in action

    Thanks Kerry!

    By the way, have you thought about creating a relay based input/output selector board that matches the dimensions of the digital attenuator? That would allow to stack them up in order to minimize space and signal path. It would simplify metal work as well (less drilling).

    It could also nicely benefit all the hassle of the attenuator implementation: using same power supply, and same encoding method (arduino).

  3. It shouldn't rotate freely. As Hakko and Aoyue tips are normally interchangeable, my guess would be your tip is defective or fake.

    I already had an experience wih a fake Aoyue tip (Different body geometry, and the tip wouldn't work after 4-5 solder joints), which is quite amazing when you consider Aoyue is already a copy of Hakko. You can't even have genuine counterfeits these days.
