Laser Scanning Microscope from Blu-ray Player #3: Increasing the Resolution

This is part 3 of my series on building a laser scanning microscope from an optical pickup unit I salvaged from a defective Blu-ray player. This version fixes some issues I had with the prototype shown in part 2. In this project, I used 3D prints from PCBWay. Get 10 PCBs for only $5 and 3D Printing starting from $4.98 at https://www.pcbway.com/?from=Doctor Volt 3D files, schematics, source code, etc: https://github.com/michalin/Blu-ray-Laser-Scanning-Microscope Special Parts: Joy-It SBC-NodeMCU ESP32: https://amzn.to/3VXhOwF OPU BDP10G: https://amzn.to/3PrssJq FFC/FPB adapter board 40 pin, 0.5mm: https://amzn.to/3PrssJq Custom 3D prints with UTR8360 standard white resin: https://www.pcbway.com/?from=Doctor Volt Tools: Camera: https://amzn.to/3kDp1BJ Blu-Ray player: Samsung BD-J5900 (No more made) Tools: Camera: https://amzn.to/3kDp1BJ Blu-Ray player: Samsung BD-J5900 (No more made) Consider supporting this channel on Patreon or become a channel member and get updates about ongoing projects and preview videos! https://www.patreon.com/docvolt Paypal: https://www.paypal.com/paypalme/docvolt 00:00 - Introduction and retrospect 01:03 - Making the construction 02:31 - Assembly of the mechanics 04:10 - The Electronics 05:40 - The web interface 06:19 - Adjustments 07:47 - Performance tests 12:34 - Conclusion
