SOLD This is a spare Coherent 210 Laser Power Meter unit I've had around for a bit. I only have one 210 sensor head but the Coherent sensor heads from the surplus meter assemblies work just as good if not better. This one includes the sensor head from the surplus meter assembly, stand...

KD 150mW Baton style DPSS laser doing its thing... Not too shabby for $136. :D

This is kind of interesting. My wife bought this Fisher Price "Light Sketcher" for my grand kids at Toys-R-Us and after playing with it a few minute using the included LED light pen, I thought I'd try it with my Blu-Ray Laser. It works great! The image stays dark for a couple minutes before...

KD 150mW Baton Style Green Laser I received this laser 28 days after ordering. It arrived in a nice vinyl covered cardboard presentation/storage case. The battery cap and safety interlock plug/lanyard were included but not assembled onto the laser. It also came with a 18650, 3.7V rechargeable...

This is a companion thread to the DIY Laser Power Meter thread. I've completed an initial design for a DIY Laser Power Meter RS-232 Interface Module and am attaching the schematic here.  This module uses a PIC12F683 microcontroller.  I'm using two of its 10-bit A/D inputs for two separate...

A few weeks ago I ordered the Romisen 30mW from DX and another 50mW CR2 from KD.  They both arrived yesterday.  The KD was DOA.  The Romisen was a very nice surprise in contrast to the huge disappointment from KD.   There was no battery included but I had a freshly charged 3V RCR123 ready...

Often forgotten..  Here's a video of some old-school laser lumia effects.   This was done with a DIY lumia wheel spinning at 1 RPM.  The wheel is a 3" diameter Plexiglas plate and was "creatively" smeared and dabbed with Duco Cement (glue).  These effects are simple and cheap.  I made this...

As promised, here is the DIY Thermal Energy Meter build thread. This is no way intended to be the end-all and be-all of laser power meters.  It's a simplified design intended for the amateur hobbyist.  It can be expanded upon but as presented here, it is intended to be an interface between a...

I built this thermal energy meter for less than $50.00.  It has a range of 0-1999mW and sensitive enough to register a cheap 5mW red pointer.  The thermopile head is capable of much higher power. The 1999mW limit is imposed by the digital panel meter display. It's powered by two 9 volt...

Nothing real special... This is the laser engraver we use to mark the enclosure lids for a product of the company I work for. It's a Laservall 20W, air-cooled, DPSS Nd:YVO4 laser.

I received my GB Blu-Ray diode in the mail yesterday (Thanks Daedal!) so I set out to build a Blu-Ray laser pointer. I started out with the idea of borrowing the torch/pointer modification that Catdog did but that the torch that I wound up with was a little different than Catdog's and didn't...

I've been running my DIY flashlight laser with a Senkat LD at just under 250mA for about 15 minutes of total run time..  Never more than 2 or 3 minutes at a time. A line has appeared through the projected spot recently and it seems to fade in and fade out randomly. It's not the lens as the line...

It's nothing special other than the pictures are interesting and that this was amazingly easy.. (Thanks to the information gleaned here) Picture with flash Picture with no flash, long exposure Another Picture with no flash, long exposure Without the flash, the color saturation is...
