I just bought a lot of seven IV-16 numitron tubes on ebay. Looks like they were the very last available...


(Image from Tubehobby.)

They will serve as displays in my future streamline-styled (or so) weather station.

purchased an NXP LPC1768 controller, it has the IDE in the cloud - see also www.mbed.org -

No particular project in mind, maybe port some of the Arduino libraries I posted on the playground when it is raining

NXP doesn't sample.  Why not stick with the good guys (Atmel).  Samples, and very nice desktop development software.

I've gotten more samples/freebies out of NXP than I've gotten out of Atmel...
(usually as a result of special promotions or tradeshow seminars, but Atmel never struck me as one of the friendlier sites WRT sampling, either.)

Reminds me of this story http://www.arunjain.com/jokes/Shit_-_A_Bird_Story.htm
copied for conveniance

A little bird was flying south for the winter.  It was so cold; the bird froze up and fell to the ground in a large field. While it was lying there, a cow came by and dropped some dung on it.  As the frozen bird lay there in the pile of cow dung, it began to realize how warm it was.  The dung was actually thawing him out!  He lay there all warm and happy, and soon began to sing for joy.

 

A passing cat heard the bird singing and came to investigate. Following the sound, the cat discovered the bird under the pile of cow dung, and promptly dug him out and ate him!

 

The morals of this story are:

 

    Not everyone who drops shit on you is your enemy.
    Not everyone who gets you out of shit is your friend.
    And when you're in deep shit, keep your mouth shut!

Just so happens, I asked for 6 ICs yesterday and they went out 2-day UPS about 2 hours after I requested them.  I think they are perfectly friendly.  Can't see how to get a sample out of NXP at all.  You search that on their site, it takes you to a page that says if you are not already a direct customer of theirs with a purchase agreement, no samples for you.

You guys are having a lot more trouble than I am.  I am not sure when this "stopped giving stuff away" happened.  I just ordered from TI too.  TI samples.  You can find parts on their site that DigiKey sells for $100 in qty 1 that they will sample.  I am trying out some motor drivers.  I did a L298 by itself (bad idea, it does not limit current - good thing my power supply does!  ) and just did a L297/L298 and wanted to try out some more modern solutions.  I got 3 each of DRV8432 and DRV8412 from TI and 5 each of AMIS30421C4211RG and AMIS30512C5122RG from ON.  All it took was asking.  On does add a $11 processing charge so it's best to fill the order, you can go as much as 7 items of 5 each without complaint.

10 IR receivers.

A lot of gizmoes are going to be controlled by the TV-remote and a really ugly remote from a BRIO toy train.

I simply have to make something outrageous that is controlled by the BRIO remote.
