Whad'ya know, another soldering tool video ... in this one I am trying to decide which one will occupy the prestigious position of being my main soldering station. The most attractive candidates are Unisolder 5.2 which I would have to assemble from scratch and Pace ADS200 which I would have buy. What do you think? ... https://www.youtube.com/watch?v=erKCA71q7cg
This quadcopter crashed into a building during automatic return. The shell took the worst of it, but we go through all the electronics anyway.

In this episode of the laser series I am showing some updates and ideas for the constant current laser, that were inspired by you! One particularly interesting idea is to control the efficient DC-DC converter with an op-amp, eliminating inefficient linear regulation completely. But before the drivers can be tested I have to fix the termination of the optical fibers. Those were burnt and unusable. Even when tediously lapping the fibers manually, some special equipment was neccessary:
