Pogo pins + laser cutter = test fixture

Eric Gunnerson made this DIY pogo-pin test jig: I decided to build a pogo-pin test jig, and since the approach I came up with was different than the other approaches I’ve seen I thought it would be worth sharing. I’m going to be targeting my laser cutter for fabrication, though I could have chosen to […]

Getting control over a 50 watt CO2 laser cutter from China

Unboxing laser cutter Co2 50 watt from China: There are people around me who think I’m crazy. And they are probably right. Who else would buy a machine from someone he does not know. I have to pay upfront. It is not clear how things will get delivered, what gets delivered, or if it gets delivered […]

Continuous Autofocus laser cutter hack

Continuous Autofocus of a laser cutter using a wiimote controller from Martin Raynsford, he writes: We were inspired by the Glowforge laser cutters ability to continuously autofocus it’s z axis. A camera mounted in the head of the laser detects a laser dot being shone onto the surface of the material and from there it can […]

40 Watt Chinese CO2 laser upgrade with RAMPS & Arudino

Dan Beaven has written up documentation on his Chinese K40 Laser upgrade: I’ve wanted to start playing with Laser Cutter/Engravers for quite a while. I finally happened across a great deal on a Chinese made 40 watt Laser Engraver with the Moshidraw software and control hardware. Wanting something I can modify and that is of better […]

40W handheld laser cutter

Martin Raynsford has written an article detailing his 40W handheld laser cutter: To generate the high voltage required to start lasing within the tube, I connected 200x 9V ‘dead’ batteries together, this generates nearly 2000V across the laser tube. I’ve been collecting these batteries for months, you can use old batteries for this because they only […]

PCBs made using a laser cutter

Joebell wrote this Instructable detailing the process of making a double-sided PCBs with a laser cutter: With a little practice, you can make excellent double-sided PCBs by combining a laser cutter with chemical etching. The basic idea is: the laser cutter blasts away spray painted etch resist, then chemicals eat away the exposed copper. Once the copper […]

Arduino based ‘Etch A Sketch’ laser cutter

Martin Raynsford writes about his latest Arduino based project: We switched out the standard controller with an Arduino (just in time for Arduino day) and connected two rotary dials to directly manipulate the X and Y axis. As long as the laser only cuts while the axis are moving then we should avoid fires. We’ll […]

LaserOrigami: Laser-cutting 3D objects

Researchers at Germany’s Hasso Plattner Institute have developed an amazing new Laser cutting 3D objects, the LaserOrigami: LaserOrigami is a rapid prototyping system that produces 3D objects using a laser cutter. LaserOrigami is substantially faster than traditional 3D fabrication techniques such as 3D printing and unlike traditional laser cutting the resulting 3D objects require no […]
