A Compact Star Tracking Tripod

The next giant leap for mankind is to the stars. While we are mostly earthbound — for now — that shouldn’t stop us from gazing upwards to marvel at the night sky. In saying that, if you’re an amateur astrophotographer looking to take long-exposure photos of the Milky Way and other stellar scenes, [Anthony Urbano] has devised a portable tracking setup to keep your photos on point.

When taking pictures of the night sky, the earth’s rotation will cause light trails during long exposures. Designed for ultra-portability, [Urbano’s] rig uses an Arduino UNO controlled Sanryusha P43G geared stepper motor coupled to a camera mounting plate on a small tripod. The setup isn’t designed for anything larger than a DSLR, but is still capable of taking some stellar pictures.

LED Bulb-shade Cityscapes

Cost-effective LED lighting for your home has opened up many doors for more efficient living, but also some more creative illumination for your living space. If you want to bring the dazzle of city lights right into your home, [David Grass] has two projects to sate this desire in perhaps the most literal way possible: Huddle and Stalaclights.

These clever, 3D printed bulbshades are possible since LEDs emit very little heat, and can be printed in a variety of designs. Huddle is named for — and illustrates — humanity’s coalescing into cities as the centre of modern life from which most of our information and technology emits. Stalaclights offers an inverted perspective on the straining heights of skyscrapers and is inspired by the Art Deco era and the expansion of cities like New York and Chicago.

3D Print Your Garden

How would you go about sculpting a garden in the 21st century? One answer, perhaps predictably, is with a 3D printer. Gone are the days of the Chia pet. Thanks to a team of students out of University of Maribor in Slovenia, today we can 3D print living sculptures of our own design.

PrintGREEN traces its roots to an art project undertaken by Maja Petek, Tina Zidanšek, Urška Skaza, Danica Rženičnik, and Simon Tržan — an engineering student who worked on the project’s 3D printer — all mentored by professor Dušan Zidar. It uses a modified CNC machine to print layers of clay soil, water, and grass seeds that germinate and sprout in short order.

The goal of the project was to meld art, technology, and nature. Hard to argue with the results. With the rising necessity of  environmentally-conscious technologies in all areas, even gardening it seems, is not lacking for innovation.

Home-Made Metal Brake

Sometimes, the appropriate application of force is the necessary action to solve a problem. Inelegant, perhaps, but bending a piece of metal with precision is difficult without a tool for it. That said, where a maker faces a problem, building a solution swiftly follows; and — if you lack a metal brake like YouTuber [makjosher] — building one of your own can be accomplished in short order.

Drawing from numerous online sources, [makjosher]’s brake is built from 1/8″ steel bar, as well as 1/8″ steel angle. The angle is secured to a 3/4″ wood mounting plate. Displaying tenacity in cutting all this metal with only a hacksaw, [makjosher] carved slots out of the steel to mount the hinges, which were originally flush with the wood. He belatedly realized that they needed to be flush with the bending surface. This resulted in some backtracking and re-cutting. [Makjosher] then screwed the pivoting parts to the wood mount. A Box tube serves as a handle. A coat of paint  finished the project, and adding another tool to this maker’s kit.

3D Printing A Stop Motion Animation

How much access do you have to a 3D printer? What would you do if you had weeks of time on your hands and a couple spools of filament lying around? Perhaps you would make a two second stop-motion animation called Bears on Stairs.

An in-house development by London’s DBLG — a creative design studio — shows a smooth animation of a bear — well — climbing stairs, which at first glance appears animated. In reality, 50 printed sculptures each show an instance of the bear’s looping ascent. The entire process took four weeks of printing, sculpture trimming, and the special diligence that comes with making a stop-motion film.

Pressure Plate LED Coasters!

Looking to use up some more of his flexible LED strip, Hackaday alum and Tindie writer [Jeremy Cook] tried for a funky accent to his dinner or coffee table: light up coasters.

Using his CNC router to carve out two pieces of translucent plastic to house four 3V CR2032 batteries, four pieces of LED strip, and some wire, [Cook] had created a pressure plate circuit that activated once a drink is set on it. The original layout of the circuit, however, didn’t work, and the space for the LED strips proved to be too small. A quick redesign and some more time with his router resulted in an almost working product. Initially intending to use screws to secure the coaster, hot glue provided the perfect amount of spring once he had thinned out the coaster top to allow it to more easily flex and complete the circuit.

Artificial Skylight Brings Sunlight To Any Room

Humans aren’t supposed to be cooped up indoors all day, but who wants to be bothered by UV rays, insects, allergens, traffic, physical activity, and other people? On the other hand, a gloomy living space generally inhibits productivity — if not making it difficult to find what you’re looking for. So, if you’re looking to illuminate any room in your place, and you have the cash and the patience to wait for its widespread release, CoeLux is a skylight that needs no sky or sun — not that you’ll be able to tell the difference.

The Italian developers [CoeLux Srl] are perhaps wisely remaining tight-lipped on how the effect is achieved, but confirm that nanoparticles in the skylight mimic the effect of atmospheric fluctuations, compressing that vast deep blue into a few milimetres while maintaining the perception of infinite depth.
