Facebook og e-post passord

noreply@blogger.com (Gaute Lykkenborg) — Wed, 09 May 2007 11:00:00 +0000

Datatilsynet advarer mot Facebook. Skåra (2007) fremhever at det kan være uklokt med tanke på personvern, og kanskje også i strid med avtalevilkårene til enkelte leverandører av e-postkontoer, å gi fra seg passordet til e-postkontoen.

Facebook ber faktisk brukeren om passordet til brukerens e-post, Register and Start Using Facebook, under registrering, slik at Facebook kan sjekke hvem av brukerne som kjenner hverandre fra før. Samtidig får Facebook full tilgang til hele e-postkontoen til brukeren, og kan i teorien lese alle meldingene som ligger der. Det er heller ingen ting som vil hindre Facebook i å logge seg inn på e-postkontoen på et senere tidspunkt også.

Men det er fullt mulig å bruke Facebook med et nytt passord. En liste med e-mail adresser kan senere lages ved hjelp av for eksempel Thunderbird, og la Facebook lese denne listen i stedet. Da er det selvfølgelig en forutsetning at det ikke legges inn personlige opplysninger på kortene i lista. For å lage en e-mail liste i Thunderbird: Klikk Adressebok > Verktøy > Eksporter ... Tast inn et filnavn og klikk lagre. I Facebook: Klikk Friends > Search your address book » > og oppgi e-post fila (Contacts File).

How to change a battery on a Casio Pro Trek PRG-50

noreply@blogger.com (Gaute Lykkenborg) — Fri, 04 May 2007 18:22:00 +0000

Introduction

About a year ago, my "Casio Pro Trek PRG-50" suddenly failed — after only a few years of operation, despite the "Tough Solar" power system.

The Tough Solar Power System

Casio gives the impression that you will never need to worry about replacing batteries (Tough Solar Power), or ever worry about the life of the solar cell and rechargeable battery (Tough Solar FAQ) that "should be able to last as long as the watch". Amazon claims that "[...] Tough Solar power (uses ctl1616 battery you will never need to change)[...]" (Amazon 2007). However, my watch clearly failed to recharge.

The Panasonic CTL1616 battery

Opening the watch, it was easy to spot the problem. The "Casio Pro Trek PRG-50" uses a "Panasonic CTL1616 2.3V" rechargeable battery, and the battery was clearly eroded. It turns out that I'm not the only one that have had this problem (Another Tough Solar with a Panasonic CTL1616 fails.). The front of this old battery says "+, Panasonic, CTL1616, JAPAN", and the back says "27".
I ordered a new CTL1616 battery, $8.50 each, from American Perfit (http://www.ctl1616.com/). Sunday, 29. April 2007 — and received it in Norway, after only 6 days, Friday 04. May 2007. Notice that "JAPAN 2" is printed on the new battery. "The original battery has the letters JAPAN without number 2 engraving." (asuoab 2006).

Opening the watch

Do not open the watch! There is a lot of small parts that you will most certainly lose. If you still insist on opening your watch, knowing full well that you are going to totally destroy it, please work with your watch inside an empty plastic box or similar, so that when you drop all the small parts, you may perhaps find them again if you are lucky.

The back can be opened after unscrewing 4 irreplaceable screws. Put them somewhere safe, and be carefull not to drop them.
Be very careful when opening the watch — and under no circumstances try to turn the watch around — because 4 tiny irreplaceable springs may disapear (asuoab 2006, Sjors 2006). asuoab (2006) indicates that loosing the springs will cause the watch not to charge the battery - following by all sorts of problems.

Replacing the battery

A clasp holds the battery down in place — use a needle to unlock the clasp (Sjors 2006). A plastic tweezer should be used when handling the battery, avoiding the battery to short circuit.

Charging the Battery

Oh, and of course you should wait for a while before using the watch until the new battery is fully charged!

Conclusion

Does the watch still work? Yes, every function on the watch seems to work OK. As far as I can tell, the watch has run perfectly since Friday 4 May 2007 — and I'm going to tell you right here when it stops working correctly (still no problems, 22 May 2012). The watch was not reset as described by asuoab (2006) and Sjors (2006), but worked anyway. The watch was not cleansed, and no silicone lubricate was used, which may cause the watch to be less watertight. asuoab (2006) and Sjors (2006) describe how to perform these steps.

Yamaha QY70 Power Supply

noreply@blogger.com (Gaute Lykkenborg) — Fri, 22 Dec 2006 23:16:00 +0000

Yamaha recommends the Yamaha PA-3B AC Adaptor for the Yamaha QY70 power supply.

The Yamaha PA-3B AC Adaptor has a rated voltage of DC 10-12V, and a rated current of 700mA (zZounds Music 2006).

Living in Norway, I have been using the following adaptor for years — still working like a charm:

Nordic Power AB
AC Adaptor
Model A31260G
Output: 12VDC 600mA
Input: 230VAC ~ 50Hz

Yamaha QY70 Backup Battery

noreply@blogger.com (Gaute Lykkenborg) — Wed, 20 Dec 2006 22:06:00 +0000

Replacing the 3V SONY CR2032 lithium backup battery on the Yamaha QY70 is easy. I replaced mine with a VARTA CR2032 lithium battery. I just removed the back cover, removed the battery from the socket and replaced it.

Press the battery towards the visible springs and lift up the battery. Very little force is needed. Avoid short-circuiting the new battery with your fingers, preferably use tweezers made of plastic. Whatever you do, do not attempt to move, remove or open the black plastic ring! Leave the black plastic ring alone!

Luckily, the battery had not leaked before I replaced it..., and the new one should probably be good for another 4 years.
