    Activity Summary E-mails Started Late April, 2023

    I noticed that Laser Pointer Forums has started sending out activity summary e-mails as of April 27, 2023. I don't remember signing up for these. I appreciate that there is a link to stop the Activity Summary or (all e-mails). Could this be made opt-in rather than opt-out?

    MP3412 Boost Regulator Board

    lasersbee: I have not built a laser with this driver. I myself am not seeking high power output, hence the conditions I ran my testing under. I'm happy if others want to push the regulator to its limits (they only cost around $7 CAD per regulator). Note that there is no heatsink pad like on the...

    Benboost Mini Version 5.1 (KiCAD)

    Hello! I am an occasional reader of Laser Pointer Forums. I thought I could contribute by helping with some electronics development and testing, as I am using the Benboost Mini version 5.0 for my own projects. Due to licensing changes with EAGLE (after the acquisition by Autodesk), I've remade...
