Fresh hacks every day
Like most of us, [Chris] has pined over the very, very inexpensive Chinese laser cutters available on eBay for a while now. When most of us disregarded these machines due to their inability to work with the file formats commonly used with laser cutters, [Chris] took the plunge. He was a might disappointed the included software didn’t allow him to … Read the rest
This is one of those ideas that’s so simple we can’t believe we haven’t heard of it before now. [Johan von Konow] is upping his holiday decorating game this year by designing his Gingerbread House in CAD and cutting it out on a laser cutter. If designed well this will easily allow you to increase the complexity of your … Read the rest
Here’s one of the best takes on a glowing display that we’ve ever seen. Currently [H] is using his creation as a fuzzy clock, but it is certainly capable of displaying just about any messages.
The project uses a wheel of luminous paper as the display surface. This has a glow-in-the-dark quality to it which can be charged up using … Read the rest
Drone technology is driving the aerospace industry as companies trip over each other trying to develop the next big thing. Here’s a good example of what we’re talking about. Lasers can no be used to keep a UAV in the air indefinitely. The trick is to add an array of photovoltaic cells specifically tuned to an IR laser’s wavelength. A … Read the rest
The Nintendo Light Gun makes a perfect burning laser. Of course it’s been gutted to make this happen. Nonetheless, the retro look can’t be beat, and the gun form factor is just what you need in a laser weapon.
This will literally burn your eye out of your head, so [Justin] and his buddies over a North Street Labs … Read the rest
Lasers normally emit only one color, or frequency of light. This is true for laser pointers or the laser diodes in a DVD player. [Kevin] caught wind of state-of-the-art research into making variable wavelength lasers using shaken grains of metal and decided to build his own.
When [Kevin] read a NewScientist blog post on building variable frequency lasers built … Read the rest
[Michiel] gave us a little shout-out by drawing the Hackaday logo with his recently completed 16×8 pixel laser projector. It uses a spinning set of mirrors mounted at slightly different angles to redirect the path of the red laser diode.
The projector is driven by an Arduino. To give it more than just a hard-coded existence [Michiel] included an … Read the rest
