How to Create Laser Art with A Digital Camera. Want to liven up your computer desktop or home page with catchy imagery? There are plenty of commercial images you can download, but a laser pointer and a digital camera will allow you to create original and spectacular desktop and home page background images that will make you the envy of the office--or at least cause your colleagues to ask where you found them. While this is not a traditional electronics project, it makes use of one of the most phenomenal success stories of modern electronics, the semiconductor laser diode. The first laser diodes were demonstrated in 1962, but they could be operated only in brief pulses and emitted only invisible near-infrared radiation. Decades were required before reasonably priced, continuously operating (CW) laser diodes became available.

While today's principle application for laser diodes is in laser read/write systems, they have many other important applications in sensing, intrusion alarms and both optical fiber and free-space communication. 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. I bought some basic materials and a project box from Radio Shack. I added some solid rods in the front just to add stability to the mount. You may also enjoy: Pocket laser engraver. For the Arduino I started out writing my own software. But while searching for a good way to control movement from the serial port I stumbled upon something called "Grbl ". This is a g-code interpreter with lots of nifty functions. As I already had everything connected to the Arduino I had to ether change my connections or change the software. Luckily it is easy to change control pins in the software. I have however changed the pin-out since then and here in the instructable I use the default pin-out of Grbl. Important: The current version of Grbl (0.6b) has a bug in the queue system. Any way you choose to do it you will end up with a .hex file that you must get into the Arduino. The Arduino needs to be set up for the job.

Grbl 0.6b '$' to dump current settings" If you enter $ followed by return you will get a list of options. You must change the steps/mm for X and Y axis to 53.333 on both. Now you are ready for the computer setup. 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) For the housing, I decided to go with a clear enclosure using ‘push on / push off’ clicky buttons. Important: This is a class 3B laser and should be used with care. Parts: I just went for the 7 color laser, not the spiro. The Build: I found out that this project is much more difficult than I had anticipated. Power Settings and Diodes: I stayed pretty close to the recommendations by rog8811 from the tutorial linked above. Red – Sony/Senkat – 92mA’s (measured 42mW’s with AixiZ acrylic back opened)Blu-ray – PHR – 118mA’s (measured 110mW’s with AixiZ acrylic back opened)O-like 10mW green – I picked the best one I had, which measured 9mW’s with a CR123.You lose a lot through the optics in the sled.

. * Turquoise – 24mW’s * Yellow – 30mW’s * Magenta – 46mW’s Notes: 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. This is a 405nm ‘blu-ray’ laser diode.

Important: This is a class 3B laser and should be used with care. I managed to get a FlexDrive inside there for an 803T blu-ray build! I found that the stock, ‘stacked’ button cell batteries were not enough to run a FlexDrive. With this in mind, I chose the highest efficiency PHR diode that I could find to keep the current as low as I could and still have good power! For the 10180 fit: I shortened the spring on the tail cap just a little, because the 10180 is just a little longer than the 3 stacked button cells that came with the host.

Considering run time (boost vs buck vs diode used), IgorT did some calculations that theoretically should allow using a higher current with a red diode build! DIY 1MW Pulse Laser Gun.
