Projecting into the Past

The least expensive video projection system with a laser light source is from Epson.

The most expensive digital projection systems with a laser light source are, of course, in movie theaters. I lost track of this link to a story that I meant to post ages ago. When the Covid pandemic hit, Sony decided to abandon the market, rather than pursue lasers as a light source.

Sony’s home projectors were also affected by the problem of UV light damaging imaging devices. The technology is called LCoS. It’s an LCD variant where light doesn’t pass through the panel, it’s reflected.

UV comes with the visible light from the UHP lamps found in every video projector before LED’s and lasers. When first reading about this problem I panicked, because my JVC projector uses LCoS. JVC issued a statement that their proprietary LCoS panels are not affected. Whew!

After ten years, my JVC DLA-HD750 is halfway through the lifespan of its third 2,000-hour UHP lamp, and I continue to be impressed with the image quality.

Exterior Decorating

This is how the patio turned out. Not too big or fancy, but not too small or plain.

We bought those resin chairs for our first house, so they must be at least thirty years old. A resin table we had was damaged in the move, making the metal table less than 25 years old. The umbrella was purchased the day the picture was taken.

To hide the view from under the deck and porch I ordered some curtains that are intended for outdoor installation.

Looking for a way to keep the curtains from sliding back and forth in the wind, I came across these table cloth clamps.

Hidden behind the folds of the curtains, they’re perfect for positioning the panels and holding them in place.
