[Announce] utility to display tablet's internal temperature
 
I wrote a utility to display N810's internal temperature. I think it should also work for N800 and N770. When idle, tablets generate almost no heat, so this sensor can also measure the ambient temperature in your room.

[user@nokia ~]$ internal-temp
23.25C

Enjoy!

Haha, your tools are great! :D

Thanks a lot!

BTW: N710's a new one :P

Oh yeah, is it me or does your website address keep changing :P?

you don't know N710 is the successor of N700 with WiMax ;-)

Nice, but..
How do you know that treatment it's necessary to give to temp1_input number?

Question: Are you certain there is only one temperature sensor in the Itablets? The Newton used two sensors, one for external temperature and one for battery temperature, for its charge-monitoring thingie.

ag2, thanks a lot for yet another app.

Is it possible to have the same or similar option like in the battery-status for monitoring over time? (i.e. switched on with the -d N flag) as well as the date/time included?

For the moment, I will wrap it to a simple script with a sleep interleaved. :)

It turns out that the last site (maemostuff) was infringing on the maemo trademark. Nokia asked me to take it down (very nicely) and I did.

Yeah, shouldn't be difficult to add. Stay tuned.

I'm not at all certain, but I doubt there's one for that purpose. Charging NiCd, Ni-MH, and, I think, Alkaline batteries* is best done by watching the temperature. But I beleive Li-ion are generally charged on their current/voltage characteristics only.

*Yes, recharging Alkaline batteries may be done, but you only get practically something like 20 cycles out of them with reasonable capacity. And they can't be charged at any decent speed, so it's not really useful enough for the charger to be marketable.**

**Actually, as I wrote that, I remembered there was a company producing "Renewal" batteries -- they couldn't be recharged, being alkaline, but they could be "renewed" in a special battery charger "renewing station". Wonder if they were just selling an alkaline charger, and plain alkaline cells (with a "Renewal" label) for higher $$.

Yeah.. I remember those rechargables.. Pure Energy sold them. I also saw an infomercial on TV from another company.

you have charger's like http://the-gadgeteer.com/review/batt...tery_recharger who you can buy.

Or you can simply charge them using a current limited source and a timer... 50mA for about 16hours for a AA one

23.25C Enjoy!
Any way to get Fahrenheit out of that? Or a script to convert the output? I don't know how much math can be supported in OS2008's scripting.

Re: [Announce] utility to display tablet's internal temperature
 
Here's an updated version that outputs both F and C:

Code:
#!/bin/sh

t=`cat /sys/devices/platform/i2c_omap.1/i2c-1/1-0048/temp1_input 2>/dev/null`
if [ "$t" = "" ]
then
  echo "No temperature sensor detected" > /dev/stderr
  exit 1
else
  c=`echo $t | sed -e 's/\(.*\)\(..\).$/\1\.\2C/'`
  f=`expr $t \* 9 / 5 + 32000 | sed -e 's/\(.*\)\(..\).$/\1\.\2F/'`
  echo $c $f
fi

Has anyone archived or reposted internal-temp? the nitapps site is offline pending renewal. I had to flash my n810 and Backup doesn't seem to keep this file. Thanks...

Re: [Announce] utility to display tablet's internal temperature
 
omweather in the Maemo Extras repository can show the internal temperature in either degrees Celcius or degrees Fahrenheit. I'm not sure this simple tool would be needed when omweather can show the temperature on the home screen, along with the weather.

When did that happen I'm sure I will be getting an email about maemobox.org soon then.

yes, what did happen to nitapps?
