Here's a screenshot of the sample application. This application currently only does one channel (0-1W) and doesn't log. However, someone is working on a logging package.

It's a start.

I'm shipping out the first batch of kits tomorrow (Monday). *Those of you that ordered them, should receive them next week.

I included all the parts for the optional current measuring circuit and also the extra capacitor for the Thermal Sensor Amplifier circuit modification. *

I should have the sample application posted here for download by the time you receive the kits.

I updated the app. again last night. *It now does logging to a file which can be imported into Excel, etc. *It also remembers config parameters.

Anyone get their interface kit in the mail yet?

oh to hell with my request for the PCB itself. I want it all! i've orded the meter head via Ebay now. I just need the other parts. I would love to get my hands on both boards.

I want to make mine alittle different. and i'm sure someone else is already working on this =)
I want to make the LCD display something I can remove via plug and play and plug in the serial adapter, so I can just change where the output is going. if i'm at home I can use my PC but if I travel I can use the LCD.

Got my kit in the mail today. It is now built and have done some preliminary tests. Seems to be working just fine.
I have configured mine for the 'optional' config and have not tested that part. I did my preliminary tests using
hypertrm and just putting my thumb on the sensor. Numbers go up and down in a predictable manner. :-)
THis is just great!!!!!!!!!! Seems like a real winner.

Thanks for all your effort knimrod !!

I recieved my lpm thermopile (thanks r0ssc0) and boards for the amp (thanks knimrod) and I'm watching this thread. I need to find some time now to put this stuff together and I plan to use this as an opportunity to learn about the adc features of the atmel avr microcontrollers and my bro has offered to help write an app in vb to interpret data from the avr. I will post anything I come up with but keep in mind I'm a real newb with this stuff, its all just an excuse for me to learn thanks specially to knimrod for bringing this great project into existance.

The last of the first batch of interface kits just sold.. *There won't be any more unless there's enough interest to buy another nine PCBs and parts. *If you're interested, let me know and I'll organize a group buy for more kits.

In the meantime, I hope hope the ones who got the interface kits will post their experience, tips and pictures here. *I'll also be working on improving the software.

I uploaded the current version of the PC application software and it can be downloaded here.

You guys do know you can measure millivolts with your sound card, and there is free software out there to do this AND log the result?? d'oh.

It's like, uhh, maybe i should invent a tank that runs on egg yolk, so i can drive around, cos cars sure don't exist!
