Yes, mine does the same. Looks like there's a capacitor on the input. The good thing is that it is very slow to drift back down which suggests a high input impedance.

Well Knimrod, you asked for pictures, so I thought i would post a couple. *My meter is working very well. *My x-100 which is rated by Nova at 122 mW avg, is floating ~117-128 on my DIY meter. One of my DIY red burners measured ~150 mW, which makes sense for the current i'm giving it. * I used the RS box you suggested, which was on the small side, and i thought about getting a larger box to make everything, sensor included, but I decided to make it with a detachabe sensor head, and I am starting to like this idea even more. *So here is mine.

And here is the back view, showing the bracket holding the sensor head to the rat-box. A single philips head screw makes the sensor head detach and allows you to position it anywhere you want with the length of the original cable.

That's a very cool idea! The best of both worlds.

My personal preference is a detached sensor on a stand/tripod but that's just what I'm used to from years of using a Coherent 210 power meter...

BTW: Are there any other usefull components on the PCB, except for the thermopile and the IC?
Since it's very big, i asked roSSco to take these two off the board and send only this. The smaller the package, the lower the possibility of our customs opening it up.

Is there anything else in there, that might come in handy?

The thermopile is 50 wide (+23 for bnc connector) x 50 tall x 40 deep.

I would also have him remove the cable and connector from the factory PCB. There may be some other small components on there but It's probably not worth sending..

I was thinking that, since I have a camera tripod that I could use that. *Although i am leary of drilling and tapping a hole in the sensor head. *How did you get yours to mount on the tripod?

BTW, as someone mentioned, with the sensor on the same face as the LPM, what you can do is set your digital camera to movie mode (12 second clip is fine) in front of the DPM, so it sees the DPM, turn it on zero it out, aim your laser at the sensor. then you can start your movie clip, and fire your laser while looking away. then you can view the movie clip of your meter readings. (My DMM has a max/avg feature, but I sure like having htis all one unit and the look of the blue DPM is nice)

There is already a 1/4-20 tapped hole in the bottom of the sensor head. That's exactly what you need for a tripod.

I decided to go for a top mount for my sensor. *I don't think everything would have fit in the case (esp w/ the 9V batteries in there). *I have the sensor pointed to the side so it will be easier to see the DPM when the laser is on the target. I used the existing screw holes in the bottom of the un-anodized part of the sink.

Since my DPM is backlit, I have decided to omit the pilot LED

The mailman has not delivered my blank boards yet, so this unit is still non-functional, however, I used a PCB-sized cutout to assist part placement and layout.

I think I will add a couple of external connectors off the amp output so I will be able to connect it to my DMM and log results on the computer.

Here's how I integrated my Interface module in the enclosure. I tie-wrapped the two PCBs together with a rubber sheet insulator sandwiched between the boards, bottom-to-bottom. After that it was just routing the wires.. It's a tight fit but it works.. The PC application and the DPM read within 1mW of each other when measuring my 270mW open-can.

There was a very limited supply from the start.. Luckily roSSco ordered mine in time. (i hope.. there were some delays, i hope it's unrelated)
