How To Build and Fit the Augmented Reality Projector of a PUMA Open Source 3D Printed Microscope

The AR projector overlays a programmable heads-up-display (HUD) onto the live optical view down the microscope so you can implement AR microscopy. Details of how to implement AR microscopy were given in a separate video (   • Augmented Reality Microscopy and the Trino...  ). This video shows you how to actually build the AR projector and fit it to the microscope. PUMA is a DIY open source portable 3D printed microscope with fluorescence, polarisation, dark ground, phase contrast, epi-illumination and other advanced features.

You can help support the project by: 1. Become a Patron:   / pumamicroscope   2. Donate via PayPal: https://www.paypal.com/donate/?hosted... 3. Simply subscribing to this YouTube channel, like, comment and share these videos. 4. Spread the word - post the news about PUMA and link to this YouTube channel on your social media sites and any other outreach method (tell your friends, colleagues, students or teachers and lecturers about PUMA, for example). 5. Consider purchasing your optics and related supplies from our affiliated online optics store, OptArc.co.uk ( https://www.optarc.co.uk/ ) --- PARTS AND TOOLS =============== For the latest details see the 'Bill_of_Materials' on the PUMA GitHub page ( https://github.com/TadPath/PUMA ). The following notes explain the changes made while preparing this video. These changes have been incorporated into the Bill of Materials on the GitHub page just prior to release of this video. 3D Printed Models Updated for this Video ------------------------------------------------------- AR_Module: TFT_Drawtube_F - modified to give more upwards adjustment to compensate for the image shift of the beam splitter for the transmitted stream. Slide_mount - new. A mount for a standard 25x75mm slide to use the AR projector as a general 0.8x objective. Cx_collar - modified to have a more reliable locking mechanism. Cx_Lens_holder - modified to work with the updated Cx_collar. Clip_lock - abolished (the new clip design incorporates it) Clip - modified to include the clip lock as one solid ring and printed on its side for extra strength. This uses the 'flats' Cura profile with normal supports 'touching baseplate only' Light_block_filter - new. This is an opaque disc 17.5 mm in diameter for use as a light blocking filter for use in the standard PUMA filter trays so you can easily block light from the main objective port when using the AR projector as a specimen projection objective. Monocular: Projector_cone - new. Ocular head projector cone for demonstrating primary objective image Aperture_46mm - new. Fits on top of projector cone and designed to take a tracing paper disc as a projection screen (glued in place). Aperture_20mm - new. Fits on top of projector cone and designed to show the 20 mm diam. FOV of an ocular with field number 20. Non-Printed Parts and Tools --------------------------- Changes of note that have been introduced with this video are that I now recommend a 14 mm long M4 screw (not 12 mm as before) to use in the front of the focus platform (to act as a post for the AR clip stay thumbwheel). I also introduce the use of the standard condenser gripper thumbwheel model modified to be used as a locknut for the AR stay mechanism so this will require an extra 3 mm long M4 nut.
