Google Drive for Documentation - Restricting Search Folders? - Page 1

content: I'm attempting to use Google Drive for both production documentation, engineering documentation, and knowledge/customer briefs.The search function is fantastic, that's why I like to use it. However, the product number that's tied to a design is carried over to production. So if a technician were to look up the mechanical assembly number, firmware number, etc it'll bring up both the engineering documents and the production documents.For knowledge briefing, I'm also trying to restrict that to make locating the specific documents much easier.When clicking on the drop-down menu on Google Search it has an option for location but this seems to be global. It's either "Anywhere", "My Files", or "Visible on Drive"Does anyone know of a setting somewhere, or an appropriate Google Labs, App or something to do this?

Clever ways of detecting screws behind stickers? - Page 1

You don't want to tear those rubber pads or stickers unless absolutely necessary.Is there a clever way to detect "hidden" screws?The simpler the method (that is, without requiring expensive specialist tools), the better, but I'd like to hear about any.

If it's a branded product there's likely information on the web from places like ifixit, youtube or even service manuals and forums such as this one. Gently rubbing your finger over a warranty sticker should not affect your rights to return - only a damaged sticker should.

content: Well, with the OP the pink lamp is a typical mercury absorption failure, or it was seriously underdosed in manufacture with mercury, probably with less than 0.5mg of mercury in there as they would contain. Likely the little droplet of amalgam dropped in during evacuation was more or less bare, not wetted with mercury like the rest of the copper shavings are. That then has just enough mercury so that for the first few hours of running there is a mercury vapour in the neon/argon fill when it strikes, but with time and heat the mercury bonds with the element wires, the phosphor coat and thus is removed from the gas column. leaving only the neon as the conductor with it's characteristic red light, filtered to pink with the phosphor and the tiny amount of white light from the argon fill.

You could certainly swap in an E6750 (2.67 GHz) or E6850 (3 GHz), as they are the same socket LGA775 and TDP.I would suspect that the quad core 95W chips might indeed be a problem. They're also on 2.4 and 2.67 GHz. For most things that don't take advantage of a lot of cores you'd notice no difference, especially with the Q6600.The only change that might be worth doing is the E6850.There are some later Core 2 Quads with decent GHz and 65W TDP: Q9595S 2.83 GHz, Q9550S 2.83 GHz. Both of those have non-S versions with 95W TDP and otherwise identical-looking specs. I'm not sure how they manage that. Aggressive throttling?

There is more of a risk of shock if your hand touched the metal of the USB socket. The schematic shows no high impedance arrangements to make the USB port safe to touch. They would probably need a proper barrier in a real product design, as its not trivial to create a high impedance path for the current ranges.

You would normally want to use higher values like 15uF or 22uF if you go with ceramic, or at least 2 x 10uF in parallel.
