Welcome from a fellow washingtonion! I have a daughter that lives up by you.

Well got a reply from Ophir about the sensor.... "This sensor is a very old model that interfaced with our DGX meter. It has been obsolete for several years. Unfortunately this sensor will only work with the DGX meter, not any of our currently offered meters. I have attached the DGX user...

Came upon this Ophir. Any idea just what it is?

Question for those who have built their own TEC based LPM's. I am getting ready to put everything together, and noticed that one of the leads attached to the TEC seems rather unstable and about to break. Is there a recommended way to "seal" or "protect" those connections? I was thinking of...

I'm going to do a write-up with pics. Publish the frizzle and Eagle schematics. I could always do a video of the lpm, although it will be on the breadboard. Once I've gotten it to work on the breadboard, I'll make a protoboard and come up with a good case. The last step will be a PCB layout.

Ok, wanted to let everyone know I'm still working on this project. I've decided to integrate the ISIS project also and change as much as I can from that project into Through Hole components to make it easier to breadboard and easier to assemble. There are a couple of components from that...

I'll look into that. I know that the DMM will require a separate vcc in, so I'm trying to find circuits that will take a wall wart of some voltage/amperage output and putting out +9v, -9v, +9v. Proving to be difficult, but will really make for a neat package that doesn't depend on batteries if...

makes sense. Next question. I finally have all the components, and am ready to breadboard while I wait for the pcb. Any way to use say a wall wart rather than two batteries?

My guess is that there is a filter on the laser that does this and should be able to be taken off.

Question about this new circuit. It's been quite a while since I've read them and there is one point that is confusing me trying to breadboard the circuit waiting for the pcb. I see several +9v and several -9v. I also see 9v1+, 9v2+, 9v1- and 9v2-. I'm thinking these last are the two separate...

Good news, it actually DID clear customs. The ebay tracker just never updated. It went from China, to Hong Kong, to New Jersey, to Ohio, to Nebraska and is slowly making it's way here.

I can do that too!

Once I get all the parts, I'll start a new thread to follow the construction.

It did ship with a battery, yes.

Thank you, I will just be more patient...Which is VERY difficult for me to do.

Greetings! I ordered a laser from a recommended ebayer dennyzhaogoods. Just had a question about Customs. I've ordered and received several lasers from China with no difficulty, but this one seems to be stuck in customs? I know it's just been a little over a week, just wondering if this is...

I sure will. Probably even do reviews

Thank you so much Rich! I appreciate it all!

Good to know, thank you! I thought perhaps it was defective, but so far everything I've gotten from him has been outstanding quality.
