Let There Be Automated Blinds!

Posted on by

More than once a maker has wanted a thing, only to find it more economical to build it themselves. When your domicile has massive windows, closing what can feel like a mile of blinds becomes a trial every afternoon — or every time you sit down for a movie. [Kyle Stewart-Frantz] had enough of that and automated his blinds.

After taking down and dismantling his existing roller blinds, he rebuilt it using 1-1/4 in EMT conduit for the blinds’ roll to mount a  12V electric shade kit within — the key part: the motor is remote controlled. Fitting it inside …read more

Super simple controller for Motorcycle LED lights

Posted on by

For automobiles, especially motorcycles, auxiliary lighting that augments the headlights can be quite useful, particularly when you need to drive/ride through foggy conditions and poorly lit or unlit roads and dirt tracks. Most primary lighting on vehicles still relies on tungsten filament lamps which have very poor efficiency. The availability of cheap, high-efficiency LED modules helps add additional lighting to the vehicle without adding a lot of burden on the electrical supply. If you want to add brightness control, you need to either buy a dimmer module, or roll your own. [PatH] from WhiskeyTangoHotel choose the latter route, and built  …read more

Talking To A Lamp

Posted on by

Barking commands at furniture seems a bit odd but with voice controlled home automation platforms becoming the norm, you may be spending more time talking to your light fixtures than your kids. In one such project, [Becky Stern] used an Alexa Dot and an ESP8266 respond to voice commands.

The design uses the Alexa Dot to interpret voice commands such as ‘Alexa turn the light ON’. The ESP8266 with a relay feather wing is used to switch the actual lamp ON and OFF. The glue between the two is the fauxmoESP library that allows the ESP8266 to receive commands from …read more

A Magic Light Bulb For All Your Bright Ideas

Posted on by

[Uri Shaked]’s lamentation over the breaking of his smart bulb was brief as it was inspiring — now he had a perfectly valid excuse to hack it into a magic light bulb.

The first step was disassembling the bulb and converting it to run on a tiny, 130mAh battery. Inside the bulb’s base, the power supply board, Bluetooth and radio circuits, as well as the LED board didn’t leave much room, but he was able to fit in 3.3V and 12V step-up voltage regulators for the LiPo battery.

[Shaked]’s self-imposed bonus round was to also wedge a charging circuit — …read more

Shapes Made From Light, Smoke, and A Lot of Mirrors

Posted on by

Part lightshow, part art piece, part exploratory technology, Light Barrier (third edition) by South Korean duo [Kimchi and Chips] crafts a visual and aural experience of ephemeral light structures using projectors, mirrors, and a light fog.

Presently installed at the ACT Center of Asia Culture Complex in Gwangju, South Korea, Light Barrier co-ordinates eight projectors, directing their light onto a concave cluster of 630 mirrors. As a result, an astounding 16 million ‘pixel beams’ of refocused light simulate shapes above the array.  The array itself was designed in simulation using an algorithm which — with subtle adjustments to each mirror …read more

Brake Light Blinker Does It with Three Fives

Posted on by

Sometimes you use a Raspberry Pi when you really could have gotten by with an Arudino. Sometimes you use an Arduino when maybe an ATtiny45 would have been better. And sometimes, like [Bill]’s motorcycle tail light project, you use exactly the right tool for the job: a 555 timer.

One of the keys of motorcycle safety is visibility. People are often looking for other cars and often “miss” seeing motorcyclists for this reason. Headlight and tail light modulators (circuits that flash your lights continuously) are popular for this reason. Bill decided to roll out his own rather than buy a …read more

Retrotechtacular: The Aerolux Light Corporation

Posted on by

The humble incandescent lightbulb is an invention just about anyone born in the 20th Century is more than familiar with. But it’s not the be all and end all of lighting technology – there are neon lights, compact fluorescent bulbs, and even LEDs are finally being adopted for interior lighting. But with the endless march forward, there are vintage throwbacks to the past – how many hipster cafes have you been to lately with great big industrial-looking filament bulbs hanging from the ceiling?

However, that’s not all history has to give us. These gas discharge bulbs from yesteryear are absolute …read more

Sunrise Alarm Clock with Organic Twist

Posted on by

Most hardware hackers have a clock project or two under their belt. A pretty common modification to a generic clock is to add lights to it, and if the clock has an alarm feature, it’s not too big of a stretch to try to get those lights to simulate a sunrise for a natural, peaceful morning alarm. The problem that a lot of us run across, though, is wiring up enough LEDs with enough diffusion to make the effect work properly and actually get us out of bed without an annoying buzzer.

Luckily for all of us, [jarek319] came up …read more

Slow Dance Appears to Make Time Run In Slow Motion

Posted on by

Rendering something in slow-motion is an often-used technique that attempts to add some ‘wow’ or ‘cool’ factor. Seeing something out in the world move in slow motion is marginally rarer — rarer still if it’s in your own home. But do it right and that kind of novelty turns a lot of heads. Enough to go 8x on a Kickstarter goal.

Slow Dance, a picture frame ringed with strobe lights, generates the surreal effect of turning small, everyday objects into languid kinetic sculptures. It’s an intriguing example of kinetic art done in a novel way.

[Jeff Lieberman], a veteran of …read more
