Les’ Lab reviews Mini Gerbil 3 controller

Les’ Lab is a technical YouTube channel that frequently covers laser equipment. He’s clearly an expert and adds a lot of value to the community. So when he mentioned he was looking for a laser controller for his old K40 style laser, I thought I’ll say thanks from the community and send him a unit.

Watch his installation of the Mini Gerbil 3 into an old laser which needed some TLC. His idea of a front window that enables visibility of the controller LEDs is genius. I am genuinely scratching my head as to why I didn’t think of that!
