Alarm on IPhone 4 + timechange (Summer -> Winter) = alarm goes off 1 hour to late

An alarm for 6am on weekdays was set and used before time change from summer till winter. On the first weekday after time change it went off at 7am.

A new alarm was made for 8:30am and it went off at 8:30am.

It sounds like a summer/winter time problem.

Does the alarms go by USA's time change? We will see monday.

Or how is it set? Doesn't look like it is set independent of summer/winter time.

HamGadgets

After some savings I had little to go spend on electronics. My choice fell on HamGadgets again.
I needed another picokeyer+, Since our 7 year girl has become very interested in learning morse code.

The package was shipped in the 22. I got it today. Only 4 days later.

I got enough 2N7000's so there is plenty for me to return some to Colin g6avk.

I'm up for trading, I have many other components in big quantities so just ask.
So just ask if there is something your looking for.

Another weekend..

The lawn has been mowed, the hedges has been trimmed..

Tomorrow i'll have a pair of sore arms tuesday or so!

..

Tomorrow is it monday and a new work week begins.

Both our 7 year old girl and our 2 year old girl has helped me over time picking up the grass and the leftovers from the hedge.

It feels good though to be done with it.

Just got my order from NKC electronics

It is not the last time i look to buy at NKC electronics

I got:

SOIC to DIP Adapter 28-pin (10-pack)
Item#: soic-to-dip-adapter-28pin-10
$19.99

For "regular" "old" sized SMD component like NE602's

TSSOP to DIP adapter 28-pin 0.65mm pitch (5-pack)
Item#: SMD-0028
$9.99

These I got to play with AD9834's and similar.

Might have to talk to one of the soldering ladies at work to solder them.. not that i can't but it would take way longer and be uglier.

HTC Desire & FreeBSD

Well all went fine till I tried to mount the SD-card from my FreeBSD based laptop ..
Well off to Google for a solution and found Mount Android phone in FreeBSD [Solution]

dd if=/dev/null of=/dev/da1 count=0


It seems not to write anything, though it fices "something" down the trail so that /dev/daXs1 is being recognized as an msdosfs formatted partition and it can now be mounted and used (8

Now off to see how to get BT obex ftp to work. Or some other form for filetransfer.. scp or sftp maybe?

ISO 8601 is a good date notation form

Today i stumbled upon the ISO 8601 date notation format. I have for a while been using the form YYYYMMDD, though the ISO 8601 says YYYY-MM-DD.

This is unifies the notation used in USA (MM/DD/YYYY) and in the rest of the world (DD/MM/YYYY).

Another nice feature is that if the ISO 8601 date notation is used in filenames they are easy to sort chronologic order.
