ARGraph datalogging add on - Open Source

Open Source schematic/firmware/PCB available here:

I made a little Arduino attachment for easy & accurate LPM data logging. It's designed such that it's compatible with the newest version of Trevor's Open LPM firmware here:
OpenLPM - The free, open-source LPM project!
and it uses Trevor's data logger here:
http://laserpointerforums.com/f70/peregrine-free-lpm-interface-80589.html

The Arduino Uno & the attachment on it will run you under 50$ for the whole set up.

I've tried to make it so it's very easy to use, just flash Open LPM onto the Arduino, and attach the red wire to 6-15V+, the black to ground and the white to the signal coming off the LPM. Plug it into your computer with a standard USB cable and start data logging!

New version!

Example of it being integrated into a DIY LPM

Thanks for looking!

Re: Add datalogging to any LPM

Very interested , adding it into my ophir head would be my goal!

I have a special one for vanilla Ophir heads in the works as well, it outputs +9V and -9V from one battery so that two wont have to be used.

Re: Add datalogging to any LPM

Nice small PCB...
We tried selling a Data Logging Option for all the other LPMs
that did not have Data Logging back in Mar 2011. It even
included an on board MCU to keep it very small and not need
a 2nd PCB.

Here is one installed in an Alpha...

There was not enough interest from the LPM community
so we stopped selling them and just use them in some of
our own projects. Hopefully you will have better luck giving
them away...

Re: Add datalogging to any LPM

@ ARG let me know when you have the finished product. I have 3x 9V so no problem there. I sure want this in my LPM. Not that i will use it very often but i like the option :tinfoil:

greetings,,

@ Jerry
Thanks! The reasoning behind using the arduino is because it's an Open platform and Trevor has already made Open Firmware for it. This way people can modify it and expand it if they want to.

@Offroad
The final products are about a month away still, I'm still working on the latest revision and then I have to send it to the fabricator and get it back before I release them.

Re: Add datalogging to any LPM

Looks great, can't wait to have this on my LPM

Re: Add datalogging to any LPM

This is fantastic. It's really nice to see hardware start to be developed around OpenLPM.

+1 when the system lets me!

Add datalogging to any LPM
easy & accurate

I have a coherent lasercheck and an analog scientech meter. What do

send them to me i will install the arduino as a courtesy to my fellow member :eg::eg:

Psh, easy. Rip out the insides, install an Arduino. Write a library for the LCD then make it so the power outputs to the LCD as well.

Re: Add datalogging to any LPM

I want data logging for my Ophir LPM too. It is great to make a output graph for the laser.
I prefer a complete kit because Arduino isn't my best knowledge of electronics.

Re: Add datalogging to any LPM

:drool: like everyone else this would be a great addon to my Ophir LPM. Very untested as well.

Re: Add datalogging to any LPM

Glad to see there's interest in this I have sent the V2 boards to the fabricator. Both the regular ones and ones for Ophir heads that will provide +9V, -9V and GND from one 9V battery to power them. Of course the regular one can be used for Ophir heads if you already have powering it sorted out.

Once I test them out I will be selling these for those who do not want to solder the 0603 caps and SOT-23 packages or those who just want to have one already set up & tested.

Re: Add datalogging to any LPM

Very nice.

Re: Add datalogging to any LPM

The boards are about 3 weeks away, the Ophir ones have a mistake on them, so those wont be available. :banghead:

The regular boards can still be used with an Ophir though, it just wont have the +9V/-9V from one battery feature.
