Mash Monitor - Page 11

**Yuri_Rage** · 07-09-2007, 06:18 AM

As some of you know, I recently made the switch to Linux (not dual boot, not Live CD...I dove right in with 100% Linux).

So, I decided to give my Mash Monitor software a try today. After a bit of gnashing and fiddling with Java libraries and defaults (not too terribly painful), I got a successful build. I only needed to change a single line of code (which could easily be done dynamically...and probably should be). My Ubuntu installation even automatically detected the Arduino board and set it up on /dev/ttyUSB0.

The single line of code that changed:
Old: private static final String PORT = "COM3";
New: private static final String PORT = "/dev/ttyUSB0";

Yep, linux is cool. I use debian at work and I'm waiting for all my stuff to arrive to be able to do a full backup of my laptop and reinstall my beloved desktop bsd.

I've been 100% Linux (servers and workstation) since RH 8 came out. I think that was 2002 ? I can't remember anymore, its been so long.

The great thing about Java is that its almost platform independent.

I know this is an old post but I was curious if anyone could offer some advice.

I want to build a board that can read temperatures in my wort during fermentation with a thermistor and possibly when I switch to AG read the mash temps. I am suppose to be learning java this summer for my computer science major so I also want to work on a program that reads the temp. for now it's just a learning project.

Does anyone have a schematic I could use for thermistor to a USB that I can then connect to a computer. I would like to build the board my self if it isn't too complicated. I do think that would be an awesome learning experience.

Any tips or help would be greatly appreciates

Look up the LM34 and LM35 datasheets for temperature sensing and how to wire them up. Check out the "DIY Submersible Temperature Probe" thread for how to make something okay to dip in your beer.
You can use an Aurdino in between the sensors and you computer. Or, even cheaper you can buy a SiliconLabs Toolstick with the F321 daughter card. Glom together some C code that is downloaded to the microprocessor to interpret commands from the USB or simply read the ADC, maybe scale it, and spew it to the USB.
