Etch a Sketch

Here's the (revised) circuit board for the Garduino Mini.

I had considered wrapping the whole thing in a ground plane, and trying to limit the amount of etchant that is required, but since this is the first time I've done a circuit board I went simple.

Here's how it turned out:

Das Blinkenlights

After much agonizing I got the Arduino Pro Mini [Clone] programmed.  The key was to choose the correct device from the Arduino programmer.

The current prototype has a bluetooth serial to beam data back, plus collectors for temperature, air and soil humidity and ambient light.

The host server will have a PostGreSQL database that stores the data, and some sort of web interface that draws some charts.

We're be going with chart.js for the charting engine and most likely some sort of PHP -> JSON quick hack to spool out data.

Arduino for Everyone

I got a bunch of Arduino stuff from dx.com (aka dealextreme).  They will be used for a Garduino project, so that we can monitor the soil moisture, light, etc for the vegetable gardens.

Tonight I assembled a temp and light sensor on the proto board.

I need to source a 3.3V voltage regulator to drive the bluetooth module, then these can start moving outside.
