Please help me find a component photocell (photoconductor) that works well in the IR range. I'm trying to find a photocell that works in the micrometer wavelength range. The market is full of Cadmium Sulfide (CdS), but those peak at a little less than 1 micrometer wavelengths.

According to
this post, electronics rule violations on planes won't really put my safety in jeopardy (by bringing the plan down or anything) but am I supposed to ignore blatant electronics usage during take-off and landing?

So I'm visiting my wife's family in Portland and just discovered that the electronics surplus wonderland known as "Wacky Willy's" went out of business several years ago. It was sort of like Archie McPhee's for Maker types. Are there other similar places that I can take my budding geek 12-year-old that are similar to Wacky Willy's?

I bought a few strands of cheap LED Xmas lights this year. They include a circuit box with several settings to make the lights flash in different patterns. The circuit box resets itself (to a new annoying setting) each time the lights are unplugged or when it shorts out in the rain, and I also suspect the box is the product's "built-in expectancy" (since otherwise LEDs might last too long to be profitable. Can I bypass the box?

What type of electronic position sensor (aka tracker) should I use to track the position of an object in three dimensions? I want to watch the position through software; I don't care about velocity, relative movement, or orientation. Also, I'm on a low budget for this. Either wired or wireless sensors would be fine.

I'm about to teach a soldering class to kids, and it occurs to me that I may blow a fuse in the room that I'm doing the event in if I plug too many in at once... Any idea of how to gauge how many I can plug in simultaneously? This is the soldering iron I have.

It is affiliated with a non-profit and reasonably high profile, I have a PR kit ready but am having trouble finding the right contacts (at Samsung, Sony, or Panasonic for example). I need a monthlong loan of a flatscreen LED display and in exchange can offer PR opportunities, exposure to a sophisticated arts audience, and VIP performance tickets - a lot to offer!

I want to put together a list of every iOS app I've ever purchased. And I've purchased a LOT. I know I can go into my account information on Itunes and pull purchase history, but it only displays in small 'batches' at a time and I can't cut & paste from there. Next thought is to pull it from Itunes receipts in Gmail, but I don't want to have to go into each email & cut/paste into another document. Is there any way to concatenate all the emails automagically? Is there another solution for this I'm not thinking of?
