I have always wanted to work with Arduino Microcontrollers and have decided to jump in Head-First and build a Weather Grapher.
This device will make Measurements of the following . . . Indoor Temp Indoor Humidity Outdoor Temp Outdoor Humidity Barometric Pressure Outdoor Light
It will make a measurement of all modes every minute, Every 12 minutes it will be averaged and stored, creating 5 averaged readings per hour. At midnight the whole day will be averaged for the Out Temp and Out Lite readings and stored to make some graphs that show 120 day Trends The display will be small OLED screen with a 128x64 display 8 buttons will cause a graph of information to be displayed . . . 1- In Temp 24hr 2- In Hum 24hr 3- Out Temp 24hr 4- Out Hum 24hr 5- Bar Pres 24hr 6- Out Lite 24hr 7- 120 Day Temp Averages 8- 120 Day Light Averages This project will involve . . . Arduino Uno 2 DHT22 Temp Humidity sensors Barometric Pressure sensor Small Solar panel Real Time Clock and some switches The Hardware part of the project appears to be simple. Have programed in BASIC before and have been spending the last week learning Arduino C++ Doesn't seem to be too much of a learning curve.
Anybody else messing around with these things ?

Not me, but it sounds like something my son in law would do. Right now, he's really into raspberry pi. He's doing lots with those.
Good luck and have fun- post a pic when you're done.

Yeah the Arduino can run a robot and make some graphics, but the Raspberry Pi can Log In to the internet and hook up to a real monitor.

Sounds like fun! I always wanted to play around with them but still haven’t gotten around to it yet. I would have to brush up on my programming since the last languages I did any real work in were BASIC and FORTRAN.

Have received 2 of these small Arduino Nano computers. Each one is about the size of your thumb. I quickly learned to do basic programming and wrote a program to graph Outdoor Light levels.
Here are some examples of a Sunrise and Sunset. The display is 2 hours wide and contains 120 samples of outdoor light, 1 minute per pixel .
Here I am talking to the Rock Crowd about computers, electronics, and programing , but I do everything and you get to hear about it . . .

What could I measure and graph for Rock Tumbling ?
Sound Power consumption

I’m tagging rrod because he has posted ( forum.rocktumblinghobby.com/post/1145116/thread) about measuring sound levels of his tumbles as well and may be interested in this thread.

Mainly I was trying to see if monitoring tumble loudness could let you know when grit has been broken down. Didn't get to anything conclusive before I upheaved my setup to make room for my 15lber. But, what I did find was that monitoring transient peaks can let you know how often stones are colliding, which is perhaps something useful for later stages and brittler stones.
