Daily Prompt: World’s Best Widget


Today’s WordPress Daily Prompt is

You’ve been granted magical engineering skills, but you can only use them to build one gadget or machine. What do you build?

Photographers, artists, poets: show us MACHINES.

Okay: here’s my invention. I’d like to see a video projector built with thousands of tiny lasers on a chip. Since the technology to make dirt cheap laser diodes in red, green, and blue is already out there (you can get retail laser pointers in various colors for $10-20), it shouldn’t be too hard to put together a 1024×768, or higher, (times 3 for the RGB pixels) on a single chip.
The advantage, here, is that you don’t need a different light source and you don’t need a screen: any flat, white surface (wall, ceiling, bed sheet on a clothesline) will do. The response time can be faster than an LCD because there’s no need for the pixels to chemically relax. And it could potentially be made small enough to fit into a smartphone, or big & powerful enough to drive 3D movie projection without too much dimming from the glasses. Heck, since laser light is polarized anyway, run two of them side by side and wear the 3D glasses.

Right now, I’m sure some electrical engineers are developing such a thing. After all, if I can dream it up on the spur of the moment like this, then somebody who gets paid to think up stuff like this is already working on it.

If not, well- Patent trolls: Spoiler alert, you saw it here first.


Update: UberGizmo in 2006 wrote of something like these ring invented by a Korean company, and said they’d be in cellphones by 2010. Rather miffed that my 2013 iPhone 5 hasn’t got one…

  1. No, no! Put the diodes on the walls and ceiling, and you’ve got the total surround video envisioned by Ray Bradbury in (?) Martian Chronicles? (?) Something Wicked This Way Comes? And then modulate brightness to match alpha waves, and you’ve got compulsory-relaxation environments (As envisioned by Tom Blackburn in “Assisted Living.”)

  2. But, the portable pocket gadget is important too. I like the changeable wallpaper (like in the Schwarzenegger “Total Recall”), but this is the pocket projector where the biggest element might be the lens and power supply.
