DIY pocket laser engraver

Photon printer, a 3D printable laser engraver build using DVD drives by Isolt:

This is an entry for the Light It Up contest on the grounds that a laser diode is a specialised form on light emitting diode.
The Photon Printer started out as a quick weekend project then quickly escalated when I saw that there was room for improvement in the current designs. The design turned out to be quite fun and I really enjoyed seeing it work at the end.

3dpBurner – A 3D printed laser cutter/engraver

p

by 3dpburner.blogspot.com.es:

It is created with the same concept as RepRap, using 3D printed parts and some easy to find “vitamins” (non printed hardware).

I tried to make it as cheap as possible, by using cheap electronics and a “low power” laser (a laser diode).
The X/Y working area is fully customisable and the max working object height is up to 50-60mm.

The cutter/engraver basically uses the 3D printed parts, M8 and M3 size hardware (rods, nuts,washers and bolts), some small bearings and GT2 pulleys and belts. I got most of the parts from my “old” RepRap printer.

The X/Y working area is fully customsable by changing the length of the 8mm rods.

The electronics uses an Arduino UNO with a cheap CNC shield and two Pololu based stepper drivers to drive two NEMA17 stepper motors.

Arduino Laser Trip Wire

FUQ36YAHVVKH6NM.MEDIUM

by ronnietucker @ instructables.com:

So, first thing I did was to get the LCD and keypad working together.

For this I pretended that it was some sort of arm/disarm (or entry/exit) thing.

My code for this part is at: http://pastebin.com/YndLneqm.

Getting the LCD wired up was tricky as most wiring diagrams for it don’t show the last two pins wired up and these are required for the back light. Check my snazzy Fritzing wiring diagram to see how I wired up my LCD screen, pot (for adjusting brightness) and keypad. The pins for them all are also mentioned in my code.

First germanium-tin semiconductor laser directly compatible with silicon chips

germanium-tin-laser-2

by Colin Jeffrey @ gizmag.com:

Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a silicon chip as it is manufactured. This presents new possibilities for transmitting data around computer chips using light, which could result in potential transfer speeds exponentially faster than possible with copper wire and using only a fraction of the energy of today’s integrated circuits.

Make high-quality double-sided PCBs – at home

Andrew Sarangan @ edn.com:

Why make your own printed circuit boards when you can get them commercially made for low cost? For one, it can take one to four weeks to receive the boards. For prototyping, this can be a major hurdle. Each design iteration will then take a month or more, and a project may need many months to get done. The DIYer can fab the board and assemble everything in one evening. That advantage is really hard to beat.

Besides time, there are other reasons to make your own board. Commercial services charge by board size, not complexity. Larger boards will cost more even if they are completely blank. I once had to make an oversized PCB because the parts had to be spaced far apart. It was a very sparse board, but getting it made from even the cheapest commercial source would have been expensive.

Modification of the Lexmark E260 for Direct Laser Printing of Printed Circuit Boards

FBS5OK4HZN0SSTG.MEDIUM

by mlerman @ instructables.com:

This is the second version of my E260 modification. It uses an ATtiny13 MCU to control the timing of the printer and make it possible to print double sided PCBs at home.

As an electronic hobbyist and inventor I often need to make printed circuit boards (PCBs) in single or small quantities. Usually these are relatively simple circuits, an MCU, some input conditioning circuitry, some output circuitry, and usually they are single sided or perhaps double sided, with just a few vias. And usually I want them right now!

Toner Transfer (TT) has become the method of choice for most hobbyists. A laser printer is used to print an image of the PCB on special “transfer paper

Engineers Build Ultrasmall Organic Laser

NewImage41

A group of engineers have developed the smallest organic laser [via] :

The 8-µm-long device, which looks like a suspended bridge riddled with holes, is carved into a silicon chip coated with an organic dye. Integrated into microprocessor chips, such tiny lasers could one day speed up computers by shuttling data using light rather than electrons. They also could be valuable for sensors and lab-on-a-chip devices.
