Expect slow miles, winter roads, way too many questions about how people stay warm up there, and what ideas we could use in the US.

James BuchanEver wonder what's inside a modern computer projector? Three main parts!
1. The colour wheel - with CMY colours and clear and what looks to be Red and Purple on this model.
2. The Lens with a primary objective lens for projecting the image and the 'combiner/secondary' for the colour which is projected onto the DLP Chip. The clear one is the objective lens that focuses the image on the screen, the colourful one is the one that reflects the colours to the DLP Chip.
3. The DLP (micro mirror) device that does the work of bouncing light out the primary (objective lens) or to the light sink that is 'wasted' and keeps light from escaping.
Each individual pixel on the screen is controlled by a very very small micro mirror that moves for each (providing an on or off pixel) which is combined with the colour wheel to create a full colour image (the micro mirrors move in sync with the colour wheel to show the correct colours as needed, all faster than we can perceive with our eyes.
Most modern cinema projectors use the same DLP technology, just on a much larger and higher quality scale.

Not pictured: the HID lamp or LED device that acts as the light source and all the cooling fans.

MetaFilterTwo great comments expertly examine the mechanics of some very different aged tech: verb on the WordPress ecosystem (https://www.metafilter.com/205678/The-WordPress-vs-WP-Engine-drama-explained#8635143) and trig on choosing a vintage sewing machine (https://ask.metafilter.com/382442/Buying-a-used-vintage-sewing-machine#5425611). You'll learn things!
