8×8 LED infinity mirror


[chromationsystems] put out a couple instructibles on building infinity mirrors. One with an 8×8 array of LEDs and one with a 32 LED ring. These are very well  documented covering the construction of the mirror enclosure as well as the circuit and code. The effect is quite nice. The 8×8 array is interesting, we haven’t seen that before. These would make a fine addition to any geek cave/electronics lab. While it looks like these were basically advertisements for a product he sells, you can definitely make your own from his instructions. We like this kind of advertising.

See-through LED display


[Ndsit] is having a party and wanted to liven up the place with some blinky lights. He’s a bit new when it comes to hobby electronics, and although we’d highly recommend inviting some resistors to participate, the LED matrix that he built is very nice. It’s 8×8, it’s big, and (as shown in the clip after the break) the lights seem to hover in midair. That’s because he didn’t use a substrate to make the display. A grid of enameled wire is strung between the four sides of the wooden frame. LEDs were gathered from a string of Christmas lights which means they’re in a holder and have insulated wires already connected. Each one was tied on at a junction point of the grid, then connected to a portion of the wire where enamel had been scraped off.
It works but there’s already one light that is out. We hope some current protection is added so that this can be used again and again.

Insane covert IR illumination


[Onironaut] over at lucidscience sent us a link to his latest project, some IR illumination panels. At first, we were mildly enticed by his usual high standard of photography and description. It was just an array of LEDs though. Still, we kept hitting the “next page” button because he goes into such great detail. Then we saw version two. Instead of simply being an array of IR LEDs mounted outside for his security camera, he has mounted 1536 IR LEDs inside an old flat panel monitor. That’s a fake monitor producing 180 watts of IR light, and we think that’s even at half power!  He replaced the screen of the display with one way mirror, so you would have no idea that it isn’t just a normal screen sitting on his desk.  Great job as usual [Onironaut].
