Pocket laser engraver.

Pocket laser engraver.
I have been trying to get my hands on a laser cutter for some time but they always seem out of reach. All the great things that can be done with a real laser cutter tickle the imagination. I feel it's time to share my latest project - a low cost laser engraver,. The workspace is a bit small but none the less it works and comes so cheap that most will be able to replicate the result. I did take a few shortcuts, as I feel I don't have the knowledge to do all the electronics I opted for readymade but low cost in favor of trying to make my own (and most likely fail). All parts used are however easy to find. I am pleased with the end result even if there is room for improvements. A word of warning is in place .

Cardboard Solar CNC test #3 above: 1 inch/minute, letters 7/16 inch tall, kerf < 0.024 inch First, this 3 axis CNC gantry system was built on a lark, out of cardboard and mostly salvaged parts. Building it kept me sane through late December - though how sane is it to build machine tools out of cardboard? It functions; which is something short of saying it works. It's fun as a pen plotter, but not well suited to the kind of precision positioning this Solar CNC project needs.

Desktop Helium Neon Laser Lamp Build Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY laser projects. I’d like to show off my new desk top laser lamp! It’s a fairly simple project and makes for a nice display piece. Basically, this is a 10 inch tube with a gorgeous laser inside. DIY Laser Engraver / Cutter If you ever wanted to do some laser engraving, this project might be of some interest to you. The circuit is basically a variable voltage regulator that is powering a high power laser. I would highly recommend laser goggles when experimenting with devices like this. Up To Date Parts List for Flack (Flying Hack) « Brooklyn Aerodrome by brooklynaerodrome Below is the current parts list as of Oct, 2012. Often parts are on back order so I have attempted to provide substitutes. Hobby King is officially in the dog house because several folks are reporting problems with getting orders.

PCB Milling PCB Milling Release status: Concept One obvious goal of making a RepRap replicatable is getting it to make it's own PCBs or other electronic circuitries. PCB Milling with the MakerBot CupCake (Almost) « Keith's Electronics Blog I crave a CNC mill for trace-isolation milling prototype PC boards and I haven’t managed to get my CupCake filament deposition machine calibrated so I can use it. (Build platform leveling and filament feed are my current showstoppers. I’ll get back to it.) I knew that someone had proposed mounting a Dremel in place of the CupCake’s extruder and that MaskedRetriever had modeled a mounting bracket; but curiously, I haven’t heard any more about using the CupCake for milling. Surely someone has done it; I just haven’t run across it.

Fantastic DIY 7 Color Laser Tutorial Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY Laser Projects. I finally finished my 7 color laser! For the guts of the project, I followed this great Laser tutorial on HacknMod. (by rog8811) EasyDriver Stepper Motor Driver Description: The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 20V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control!

Quadrocopter for 1 day for just $ 120 dollars - DIY I plan to create a quadrocopter as a platform for a flying robot for a very long time. I did my first calculations and ordered the parts a year ago. However, to create a copter just to fly, operating it with a remote control or even in FPV mode is not my ultimate goal. Therefore the copter should be as flexible as possible and less expensive. All required parts for the copter are available, but to build the copter is a simple thing only in theory. It requires variety of skills, such as a programming, engineering and so on.

PCB CNC aus Metalab, dem offenen Zentrum für meta-disziplinäre Magier und technisch-kreative Enthusiasten. Introduction CNCs can facilitate in the creation of PCBS: Manual etching and then using CNC to drill automatically. Cutting out the board , to have round PCBs, or similar.

Online » Arduino GRBL We’ve written about Grbl before, the G-code interpreter, that can be flashed onto Atmega328-based Arduinos. Our new project contributor, Riley Porter, has a project that he’s just shared with us. It’s an Arduino Shield that plugs into an Arduino and turns it into a 3-axis CNC controller. Powerful Blu-Ray Laser on a Keychain Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY laser projects. I picked up this little key chain light at Lowe’s. It is made from a solid piece of brass. It is very heavy duty, but very small. Beam shot – with smoke. Make Your Own DIY CNC This instructable outlines the assembly process of my 2nd generation CNC machine which I designed to be simple to build and quiet enough to be apartment friendly. I have included example projects that I have made in the first two weeks of using the machine to demonstrate its capabilities. This is the second CNC machine that I have designed and built. My first machine was based off of oomlout’s instructable “How to make a Three Axis CNC Machine (Cheaply and Easily)” (by far my favorite instructable and the one that got me hooked on the site). It was moderately successful, cutting a number of parts from foam (a summary of parts made can be found on my abandoned blog here along with some build photos). The lack of overall stiffness and play in the linear mechanisms meant that plywood and plastics could not be cut effectively.
