High ceilings can make a residence feel open and airy, but they often come with difficult-to-reach light fittings. To better deal with that, [mattwach] built a motorized light bulb changer …read more Continue reading Motorized Device Helps Swap Out Hard-To-Reach Light Bulbs
If you work on old equipment, you know that there’s always that tense moment when you first plug it in and turn it on. No matter how careful you have …read more Continue reading Bright Lightbulb Saves Old Radios
Sure the box said they would last for years or even decades, but anyone who’s picked up some bargain LED bulbs knows the reality is a bit more complicated. Sometimes a …read more Continue reading Salvaging Working LEDs from “Dead” Light Bulbs
No one likes a flickering light source, but lighting is often dependent on the quality of a building’s main AC power. Light intensity has a close relation to the supply …read more Continue reading Measuring LED Flicker, With Phototransistor and Audio App
We’ve always enjoyed having a few indoor plants around the Hackaday dungeon because they just make the days more cheerful. Apparently there’s a big craze for them right now, which …read more Continue reading Light Bulb Plant Propagation Station is a Bright Idea
Normally, when we pick out something to carry the “Retrotechtacular” banner, it’s a film from the good old days when technology was young and fresh, and filmmakers were paid by …read more Continue reading Retrotechtacular: The Secret Life of the Electric Light
These days, we have LED light bulbs that will last a decade. But it wasn’t so long ago that incandescent lamps were all we had, and they burned out after several months. Thomas Edison’s early light bulbs used bamboo filaments that burned out very quickly. An inventor and draftsman named …read more

Security researchers have shared some details of vulnerabilities they have found in Philips Hue smart bulbs that could be exploited by hackers to compromise networks remotely.
Read more in my article on the Hot for Security blog.

With most of the apparatus and instruments we now take for granted yet to be developed, the early pioneers of the Electric Age had to bring a lot to the lab besides electrical skills. Machining, chemistry, and metallurgy were all basic skills that the inventor either had to have or hire in. Most of these skills still have currency of course, but one that was once crucial – glassblowing – has sadly fallen into relative obscurity.
There are still practitioners of course, like [2SC1815] who is learning how to make homemade incandescent light bulbs. The Instructable is in both English …read more

Some projects end up being more objet d’art than objet d’utile, and we’re fine with that — hacks can be beautiful too. Some hacks manage both, though, like this study in silicon and gallium under glass that serves as a bright and beautiful desk lamp.
There’s no accounting for taste, of course, but we really like the way [commanderkull]’s LED filament lamp turned out, and it’s obvious that a fair amount of work went into it. Five COB filament strips were suspended from a lacy frame made of wire, which also supports the custom boost converter needed to raise …read more
