Thought I would share a bunch of pics from my 2 LPM projects. But first a word from our sponsers....
The cases are from 2 PL lasers from Sky.
Purchased the TEC based one from Awillis (he did a great job with it) and then modified it to run on parallel 9V instead of just one as I added a blue display to the top. With this unit, everything is switched on with a single switch. You will see on that I put some spacers on the front in case I want to tip the display so that the blue is facing me and the red display won't be supporting the unit. Added Screw down type connectors that can accept banana plugs for the sensor reading so you could use anything such as the Fluke 87 to read mv if you want (has a white back light).
The Ophir based one I built. Some of the build came from taking what I liked that others had done and implementing those things.
This box also has a red and blue display but on opposite sides. The Ophir is run off of (2) 9V batteries while the displays are powered by a (4) AA battery holder with eneloops (got this from Blords design) providing the 5V so power is completely separate. The Ophir has its own dpst switch and the displays are switched separately from each other with spst switches. Also added the same screw down banana plug connectors for using a Fluke 87V (white back light) or whatever you want. This unit can be used with any combination of red/blue/DVM you want. It has a USB connector going to the Ophir (got this from Awillis design).
Both units are pretty crowded inside their project boxes. The biggest reason for not shortening wires and making certain things are neat is because I may change/modify or redo them.
The TEC one is fairly neat although I didn't cut back the extra 9V wires for the added battery or the wires going to the top blue display as it makes it easier to remove the top and disconnect it. Has the added bonus of being able to put both displays next to each other if you wanted to.
The Ophir one has allot more wires. As I said above, I may change everything around or pull everything out and do something different. For now, it all works.
Have not yet done any testing on the difference between running/reading multiple displays with the same signal to see if there is any substantial signal loss but I will.
Could feed signals from one box to the other.
Anyways, the pics aren't so great when the units are lit and I had some glare plus the Flukes have screen protectors on them.
The signal screw down terminals can take banana plugs from the top or sides. Have Fluke adapters that I could have used instead of just sticking the probe ends so it wouldn't have looked kind of stupid having the leads sticking up
In the second to last pic you can see that the display reads 6mv while the Fluke reads .2mv. That is because you can hit the REL button on the Fluke to zero out the display
Once again, should have vacuumed first White cat leaves a path of destruction everywhere
