Infrared Flashlight with Screen Uncovers What’s Hidden

by James Hobson August 01, 2016

Flashlights are handy around the house, but what if you want a stealthier approach to illuminating the night? Infrared LED flashlights can be acquired at relatively low cost, but where’s the fun in that? To that end [johnaldmilligan] spent a couple hours building an infrared flashlight-gun with an LED display to venture into the night.

[johnaldmilligan] disassembled a handheld spotlight to use as the housing, leaving the trigger assembly and 12V DC charge port in place. A miniature camera was used as the video source after removing its infrared filter. Note: if you do this, don’t forget that you will need to manually readjust the focus! The camera was mounted where LED Array Diagramthe flashlight bulb used to be instead of the LED array since the latter was impractically large for the small space — but attaching it to the top of the flashlight works just as effectively. The infrared LEDs were wired in eight groups of three LEDs in parallel to deliver 1.5V to each bank and preventing burnout. Here is an extremely detailed diagram if that sounds confusing.

Unusual 72-Bulb Display Mechanism Found in Vintage Clock

by Cameron Coward July 30, 2016

It’s hard to beat a vintage clock for something that you can hack, and that your significant other might actually let you display in your home. It’s practical and it’s art all at the same time! But, finding that perfect vintage clock for restoration can be a bit tricky. A crowd favorite is to choose something with intricate mechanisms and gears — the motion of a mechanical display is just so fascinating.

[Gavin] managed to find a clock that is every bit as interesting without any moving parts. The clock uses a unique system of bulbs and screen masks to …read more

A One LED Clock

by Jenny List July 29, 2016

Esoteric clocks are something of a staple among hardware hacker projects. If it can be made to tell the time correctly, even if only twice a day, the chances are someone’s made a clock from it. And if the only person who can read that clock is its creator, so much the better. Universal accessibility is not always a virtue in the world of unusual timepieces.

[Setvir] writes to us with details of his One LED Clock. It’s an Arduino Pro Micro with an RTC module and an LED. That’s all, time is communicated to the world through LED flashes. …read more
