Blue Peter Badge!

It won't mean much (anything?) to non-UK readers, but #2 son's Instructable has earned him a Blue Peter Badge! On a whim, after he got so many favourable comments, I emailed Blue Peter and told them about it.He got the badge in the post today (it's the blue one ), which probably means he was mentioned on the programme, and the site may have been as well (have we had a spike in young UK members?) (I've emailed BP to ask).An absolute mystery to people outside the UK, but a major event in the life of any UK child.

Blue led photography...

I just took some new pictures for my BraceLED 2.0 I'ble. And look at the picture of the bracelet with the blue LED's! The reflection of the blue light on the white surface (=paper sheet) is highly overexposed! How does this happen? Is the cmos sensor in my Nikon D300s over-sensitive to this color of blue? A picture of a red-led-bracelet under (almost) the same conditions has no such effect. Picture red BraceLED: iso800, 35 mm prime, f/4, 1/20 Picture blue BraceLED: iso800, 35 mm prime lens, 1/15

How to fix blue screen? Answered

Hello I hope that all of you are fine. I recently bought a second hand HP Pavilion laptop from eBay… when I received it I came to know that there was a problem with the wifi reception… I intended it to repair myself… so I unscrewed the LCD and came to know that the connections for the wifi were broken, so I soldered them, while doing so small bead of molten soldering wore fell on the LCD, but only damaged the plastic protection and found no dead pixels when it was turned on after fixing it… the windows started up pretty good… got the wifi signals as well but after a minute or so… one or two pixel size dots appeared on the LCD and after that the blue screen appeared… I tried to restart the laptop again but the blue screen appeared every time restarted it. I tired to restore the laptop, fix the startup, also tried to run the safe mode, but everything was useless as I  got blue screen every time… the laptop manages to operate in safemode with command prompt only once and as I tried to restore the system the blue screen appeared again… further more it sometimes gets past the windows loading in the widows repair section but when it loads the resolution changes and I get a blue screen again… it also hanged while repairing setup for the windows was operating... So a lot of different hang ups… but 99% of the time I got blue screen on all the options available… I am attaching the blue screen that I usually get… it would be so nice of you if you could guide me and help me fix my computer. Please see the attached pic Kind Regards Raishikoh

The bluetooth is powered from USB which is 5 volts, correct?   Would the 6 volts from the AAA batteries damage the bluetooth receiver?  What about current?

Will I die if I eat "methyl blue?" (Or will my pee turn blue?)

Because who doesn't want to have blue urine? :PI can remember guzzling food coloring to get the effect, but then I found this. My question is: Will Methyl Blue give the same effect as Methylene Blue? The MSDS says that methyl blue "may be harmful if swallowed," but that pretty much goes for anything. Wikipedia makes a point to say that "Methyl blue should not be confused with methyl violet or methylene blue, two other stains," and so I know that they are different. How much different is the question here.Btw, methyl blue is available at your neighborhood pet store in the aquarium section as brown, granular crystals.

I managed to find a firmware update although this stopped part way through demanding administrator rights which I gave it but it still wouldn't work :L I'm using the new macbook pro with retina display if that helps with motherboard compatibility.

Why do yellow (amber) & lime green LEDs suck?

In my experience, I have dealt with many colors of LEDs, and from what it seems, red, neon green, and blue LEDs tend to be pretty good at producing light as well as surviving abuse. They also tend to require the least amount of current. However, I have found that almost all the the classic lime green and yellow LEDs are very different, and generally don't give much light output even with significant amounts of current! I have a couple of ultra bright red and blue LEDs at the moment that will glow bright enough to see them easily only a 100 microamps! That is something I simply cannot do with any of the yellow or green LEDs I've ever had! A bit of research shows that GaN and InGaN is commonly used for the blue and neon green LEDs, while GaAsP, AlGaInP, and GaP are typically used for the old-school red, amber, and lime green LEDs. I imagine brighter and more rugged yellow LEDs must exist, given their use in stop lights and road signs. Do they in fact exist? Or is our yellow LED technology still stuck in the 1980s due to little interest in them and little to no R&D;? The reason I ask is because I want to build a light source utilizing amber and blue LEDs to mimic white light, and I'm purposely trying to select colors which will give a white light w/ extremely low CRI. However I want yellow LEDs that are a closer match to blue LEDs in terms of intensity, and preferably, efficiency. I did some small scale experiments with some unknown LEDs salvaged from christmas lights, and I am impressed how poorly this light renders colors! (and how quickly my 15 ohm resistor went up in smoke driving all the yellow LEDs I had to use to equal the light from a couple of blue LEDs!) although the light hitting white paper appears purplish white, colored objects seem ghostly and take on either a deep blue, muddy grey, or yellow. Perfect for maybe a haunted house ambient lighting! Add a 50Hz capacitive driver to get some good flicker and presto, worst light quality EVER! :D
