Arduino UNO R3 mini laser cutter:

A few years ago I saw an Instructable where Groover had used a pair of DVD-RW drives to make a pocket laser engraver. Inspired by the idea, driven by the recent purchase of a full-sized 50 watt CO2 laser cutter, and roused by the launch of the Microcontroller contest I took the decision to have a crack at making my own mini laser engraver.

Laser-Cutter

You can use this cutter to cut very accurate PCB stencils on your home:

Are you sick and tired of using a tooth pick to apply solder paste? Are you still using through hole components because you don’t want to deal with soldering surface mount devices (SMD)? If so, this post provides you with guidelines for building your very own laser cutter for cutting PCB stencils. With a total cost of approximately $200 (it can be significantly less if you already have parts laying around), this project can pay for itself very quickly. While you can get “low cost” stencils for your PCBs, they still can be quite expensive if you are only creating one or two boards.

Here is a short video of a CNC hot wire foam cutter that is being controlled with an AtMega32u4 breakout board. It was programmed using the Arduino IDE by pressing the reset button and clicking on “upload” a second later. I have to make a few more videos providing details. I was surprised at how much the little thing could do; thanks for making such a fun little board.

Bart from buildlog.net shares his latest DIY laser cutter design, the 2.X laser. [via]

The second generation open source laser cutter/engraver design from buildlog.net is complete. The new machine is called the Buildlog.net 2.x Laser. The name comes from the fact that this is the second generation machine and it is basically a 2 axis design. The third, vertical axis, is manually controlled with an optional upgrade to digital control. The 2.x Laser takes all the optimizations learned from the first laser and all the other lasers documented on buildlog.net forum.

The usable work envelope is 12” x 20” x 4”. The internal design has been optimized so the overall size of the machine is much smaller than the previous design and can easily fit on a small table. It is designed to work with 40W CO2 lasers sealed gas lasers. The frame is built from inexpensive 20mm aluminum T Slot extrusion and the skin is made from a painted aluminum and HDPE laminate.

This project shows how to build a Experimental laser cutter based on low power diode. This laser can successfully make cuts using 1W laser cutter with a Z-axis control. Z-axis control allows the laser diode itself to move up and down like a saw. That motion moves the beam’s focus and makes cut more effective.

Check out this nifty automated strip cutter for surface-mount components built by some Dutch students from printer parts (stepper motor and LCD display), an Atmel ATMega8 controller, and a servomotor.
