[DIY Perks] has long been a fan of lights that accurately mimic real daylight. Often choosing high-quality LEDs for his projects, lately he’s taken a different tack – using broken televisions to produce attractive home lighting solutions. The hack involves removing the backlight from the damaged television or monitor. These have a powerful white light […]
Who would have thought that some day we’d need programming jigs for our light bulbs? But progress marches on, and as there’s currently a number of affordable Internet-controlled bulbs powered by the ESP8266 on the market, we’re at the point where a tool to help update the firmware on the light over your kitchen sink […]
The lightsaber is an iconic weapon from the Star Wars franchise, designed in all sorts of shapes and colors. Several fan-made versions have been built as well, quite a few of which use the almost ubiquitous neopixel. [Tirenoth] decided to build his first lightsaber using a series of neopixels, but decided on a unique build […]
A browse through his collected works will tell you that [El Kentaro] loves to build electronics into interesting enclosures, so when he realized there’s enough room inside a 150 ml plastic syringe to mount an ESP8266, a battery, and a copious amount of RGB LEDs, the “Packet Injector” was the inescapable result. Granted, the current […]
You’ve probably seen multicolored flashing LEDs embedded into clear plastic cups or coasters before, they’re quite commonly used in fancy restaurants that also feature animatronic characters and a gift shop on the way out. But have you ever wondered about the logistics of maintaining such devices? When the anthropomorphic rodent shuts down for the night, […]
In this day and age, production values are everything. Even bottom-rung content creators are packing 4K smartphones and DSLRs these days, so if you want to compete, you’re gonna need the hardware. Lighting is the key to creating good video, so you might find a set of flexible panel lights handy. Thankfully, [DIY Perks] is […]
Building displays out of LEDs can be fun, but quickly becomes tedious as the pixel count increases. At this point, it’s worthwhile investing in off-the-shelf panels that have everything pre-soldered and ready to go. [Tom Hammond] wanted to run a P5 panel, and put a Raspberry Pi to work to get it going. P5 panels […]
Building giant LED walls comes with a serious set of challenges. Whether they lie in power, cable routing, or just finding a way to clock out data fast enough for all the pixels, it takes some doing to build a decent sized display. [Phill] wanted a statement piece for the office, so rolled up his […]
When [Patrick Hickey] spent a tidy sum on eBay to purchase a pair of seven-segment displays used in the Launch Control Center at Kennedy Space Center during the Apollo program, he could have just put them up on a shelf. It’s certainly what most people would have done. Instead, he’s decided to study and document […]
Senior college projects are the culmination of years of theoretical learning finally put into practice. For many students they are their first experience of doing some proper, real world engineering. [Melangeaddict] chose to take on a persistence of vision display for his final project, and learned plenty along the way. The display consists of a […]
