My first post here since 1999. Just rejoined the list after a small
digression into other fields. The world has changed in the meantime.
Does anyone know of any projects on using an iPhone as a simple datalogger?
eg a timer (simple break a light beam to start, break a light beam to stop)
- or even recording a lot of time intervals. Or a counter.
I'm assuming the OS inside is able to do this, I'm just not sure how easy it
is.
I did a quick search: but most references in the list were "Sent from my
iPhone"

finger against
(one of the ) lenses and point it towards the Sun, he said.
The app displayed my pulse rate - which is apparently helpful to folks
who want to
set their resting pulse rate down by graduated exercise.
A few days later I showed him the stunt app on my dedicated device: a
pulse oximeter:
%oxygen saturation and pulse rate. This is the device that goes for $25
on up, and has
an interesting operating principle: Two LEDS shine through the finger
nail: one is
red the other infra red:
the spectral sensitivity differs as between arterial and venous blood.
To sharpen
the match to O2 saturation,
readings are taken at the systole and diastole, and the diastolic
reading is subtracted
from the systolic reading to subtract common mode artifacts from the
systolic,
arterial oxygen rich reading.

If I remember correctly you were in Christchurch. If you are still
there, I hope you did not suffer anything nasty from the earthquake.

resultant acceleration from the sensors in the iPhone. If you want to
go a step further, get the Pasco Air-Link, plug in a PasPort sensor,
pair with your iPhone (bluetooth) and you can record data directly to
the iPhone. Not cheap but works well (and we already have a good
range of sensors). It works even better on my new iPad2!
Not quite what you were asking for but well worth looking at.
