Tricorder from Moonblink
A simple tricorder for Android, using your phone's real sensors to detect magnetic fields, gravity, etc. Detect buried powerful magnets! See the passing gravity wave from a distant collapsar on your phone screen!† Be a mega-geek! Etc. Please click on this link for the full details on this amazing scientific instrument. Tricorder . Have your barcode reader ready and download this in style. You will find the full article and details there.

† Actual device sensitivity may be insufficient to detect gravity waves.
Tricorder is a Trekkie geek toy that turns your Android phone into a Tricorder. However, it's not totally a toy, as it uses real data from your phone's sensors -- you may be surprised at how many sensors your phone has. Currently it can display acceleration; the local magnetic field; an analysis of the local acoustic environment; your location from various providers; the availability and strength of cellular and WiFi signals; and the current state of the Sun and solar wind, including current pictures of the Sun.
Inspired by:
* Jeff Jetton's Tricorder for Palm Pilot
* And, of course, the work of Gene Roddenberry
Tricorder is an open project; see below if you'd like to join in.
Accuracy is limited to what the sensors can provide. In particular the magnetic field sensor on the G1 phone seems to be pretty erratic, though it sometimes works quite well; on the Droid, it seems to have some pretty serious issues. This will affect both the MAG tab and the compass in the GEO tab.
How to Use¶
Use the buttons on the left to select the mode:
* MAG: monitor the local magnetic field
* ACO: acoustic analysis; waveform, frequency and sound level analysis of the ambient sound
* GEO: display geographical information (enable GPS for full info)
* EMS: scan the electromagnetic spectrum for radio signals -- currently displays cellular and WiFi signals (you have to enable the WiFi to get the latter)
* SOL: display current solar activity data -- downloads current solar data in the background (may take a while) and displays it along with current images. The gravitational and magnetic field displays show the corresponding field information as a 3-D plot with X and Y on a cross-axis plot, with the Z value shown beside it. The elevation of the field above or below the X-Y plane is shown on a separate indicator. The absolute magnitude of the field value is plotted below, and the numeric data is shown below that. Much more detailed information is available in the help pages in the app itself.
