Schematic for using the headset input by Osamu Higuchi.  He notes:

"At first, I was trying to connect the output to mic input through
decoupling capacitor, but iPhone did not detect the signal. Then, I
happened to realize that I should have connect without the capacitor,
and it worked. The point is that you should connect iPhone's mic input
to the resistor without a decoupling capacitor.
It seems that iPhone detects DC load to switch input to external mic.
Otherwise, it would pick up hum noise just by being touched on the mic
terminal on the earphone jack.
---
The points of this schematic are:
- Divide the output voltage (in this case, about 9Vp-p) down to about 0.1V
- Do not decouple the output and iPhone mic input. Let the DC bias on
iPhone mic input drop"



 
 
 
 
 
Version 1.3.4, 1.3.4a on an iPad 2, by Laurent Lieben

By routing a Monster earphone (as mic) from the Geiger counter's speaker through the iPad's headset in jack, the majority of noise and volume issues are eliminated with no soldering or electronics work.  A clever hybrid solution.




If you would like your setup to be featured here, please email me, I always think it's cool to see Geiger Bot in action.

Fukushima Imagery - Thermal Satellite Images

As a little side project of mine, here are three thermal images from the USGS' Landsat 7.  This is the "high gain" thermal IR band (62).

Note all images are consistently colored for temperature and can be directly compared.

 
 
 
 2011-02-23 2011-03-11 2011-03-27
Note the lukewarm discharge of cooling water from the plants.

Thermal cannot penetrate water.
Note how the coast has gone dark/wet.
Still some flooding present.  Plants remain dark.

 
 

In case you couldn't find them:

Bottom: spent fuel storage, 62 C
Top: reactor vessel, 108 C



Comparison -- False Color IR "Land-Water Boundary" (4-5-3)


These images are false-color infrared in order to better show areas of flooding which will appear dark.

The surprising thing here is how much of the flooding is still present.
