Since I intend to do more SMD soldering in the future, and I also want to offer my kids some insights into the microcosm, I decided to buy a microscope with a rather big screen plus HDMI output.

I chose the Andonstar AD407 with a 7 inch creen, SD card picture and video recording. Up to 270x at 2160p resolution, 4megapixel sensor.
Fine for electronics, and up to dust/hair size discovery, not enough for biological stuff.
