The boys over at North Street Labs built a handheld burning laser and made it look super simple. Well it’s not. We don’t think it’s hard either, but the only reason it looks so easy is because they really know what they’re doing. The first step was to source the best parts for the application. [...]

It’s not too often that we cover food here on Hackaday, but when we saw how a laser cutter was being used to help enhance the look of sushi, we decided to share. Even if you don’t enjoy sushi, it’s hard not to argue that it can often be more like edible art than simply [...]

Readers of Hackaday may have noticed the weekly posts featuring whatever [Dino Segovis] of Hack A Week has cooked up in the last seven days. For [Dino]‘s one-year anniversary, he’s pulled out all the stops and put together one of his coolest hacks to date. It’s a laser oscillograph that projects waveforms on a screen just like an [...]

[Marco] has had some fun with OpenCV in the area of face tracking. Using an older laser project, he has cobbled together a system that will track a face and put a laser on it. While he is just using this as a proof of concept, it goes without saying that you probably shouldn’t mount [...]

This is the gauntlet; a place where things are tortured in ways that only an engineer could appreciate. Today’s victim is a 1.0W green laser module, manufactured by Suzhou Daheng under the brand name “DHOM”. As far as Chinese laser manufacturers go, Suzhou Daheng is about one rung lower than CNI in terms of quality. Although US companies [...]

[Brian] really liked his Samsung color laser printer right up until it was time to replace the toner cartridges. A full set of toner cartridges sell for about the same price as the printer itself, so [Brian] figured he could simply refill the toner in the cartridges he already has. The printer sends out the [...]

[Valentin] wanted to experiment with 3D scanning some objects he had around the house, but says he didn’t want to buy a line laser for the project since they are pretty expensive.

[Bill Porter] continues finding ways to help out at the local museum. This time he’s plying his skills to fix a twenty-year-old exhibit that has been broken for some time. It’s a laser spirograph which had some parts way past their life expectancy. He started by removing all of the electronics from the cabinet for [...]

[Bradley Gawthrop's] biggest gripe about his laser cutter is the lack of Mac support. We don’t think we’d have any gripes if we owned one of these (yeah, that’s a lie…) but we can understand his second biggest issue which is the inability to see the work piece once it’s inside the machine. He figured [...]

Here’s another project that reminds us of the shooting games at a carnival.

Back in 2001, [Helmar] made an awesome monochrome video display out of a red laser pointer and a spinning 18-sided mirror.

Here’s a laser cutting technique that makes thin plywood bendable. By cutting away elongated diamond shapes from the material, a lattice of strips connected minimally by alternating tabs is left over. The wood is then bendable, and it must be somewhat durable since the idea came from a product that uses the technique as a [...]

With the introduction of the Kinect, obtaining a 3D representation of a room or object became a much easier task than it had been in the past.

3D display technology is fairly limited. Most 3D displays out there rely on either prisms refracting light from a normal flat-panel display, or shooting lasers into some sort of space-filling device.

[Rich] was having quite a bit of fun with his newly-acquired laser cutter, but was not impressed by the stock aiming laser that came with it.

This laser display is persistent thanks to a glow-in-the-dark screen. [Daniel] built it using a Blu-ray laser diode.

Here’s a simple and interesting idea that increases the visual persistence of a laser scanner image. Using glow-in-the-dark paint, [Daito Manabe] prepares a surface so that the intense light of a laser leaves a trace that fades slowly over time. He’s using the idea to print monochromatic images onto the treated surface, starting with the [...]

Without a doubt, Laser Projectors are a great way to project large, bright images on any surface you can imagine. With a high enough quality projector and software package, excellent images and visualizations can be displayed in real time. [marcan], of the openkinect project, decided that there were not any open source laser projection packages [...]

Tired of breathing all the noxious fumes your laser cutter puts out? Yeah… we don’t have a laser cutter either. But [Jeri Ellsworth] does and she needed a way to evacuate off-gases generated during cutting so that they don’t damage the laser cutter, or her lungs. What she came up with is a containment box [...]

[Drake Anthony] makes building a cutting laser from a PC look easy, and it seems like it actually is. Almost everything you need can be found in a dead desktop unit. The diode is pulled from a DVD writer (16x or faster), with the power supply unit, and heat sinks from the processor and GPU being [...]

Here’s a surprisly simple way to build yourself a laser-based listening device. It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red for aiming, and the other is infrared for measuring the vibration of a surface. Point the transmitter at the window of the [...]

[Shay] and his friend built some battling robots for a school project. Instead of destroying each other’s robots with saws or torches, they are playing laser tag. Each robot sports an eeePC, a laser pointer on a movable arm, and some photoresistors. The goal is to get your laser to hit the other robot’s photoresistor [...]

This laser message scroller is built with inexpensive parts. The heart of [Raul's] system is a spinning pill-box with eight mirrors on it. Each redirects the laser to a different vertical portion of the projection surface. There are eight small arms on the apparatus that each break the beam of an optical sensors as it [...]

This laser engraver was built using printer parts, a CD-ROM carriage, and some homebrew electronic boards. The laser diode is a 1-Watt model similar to what we saw used as a weak laser cutter back in August. When the width of the material changes the focus of the laser is affected so the diode was [...]

[Nyle] was interested in building lasers at home but felt that the exotic parts list was just too daunting. That was, until he discovered T.E.A. lasers. T.E.A. lasers can be constructed from a few bits of aluminum and some high voltage. They emit UV light, as you can see in his examples where he shoots [...]

[Owen] contacted us to show us his site dedicated to his CO2 laser cutter build. He spent about 2 years and roughly $15,000 putting it together, so this is not small build.

We covet laser cutters and this diy model with a 1 Watt IR diode may be well within our price range. Most commercially available laser cutters, and some homemade ones, work in the 20-100 Watt ranges, using a CO2 laser. They have more than enough power to cut right through a lot of materials so [...]

[Jarrod] sent us a link to this home-built laser projector after seeing a different projector that we featured yesterday. This system is fundamentally different.

Two of these are controlled by an ATmega64 to [...]

Ok, we’ll start this off by saying, looking at lasers can damage your eyes. Be careful.

Once locked-on, it’s death to the filthy blood-suckers.
