How to add and power a Bluetooth receiver to battery powered speakers? Answered

I have a iHome speaker that is powered off 4 AAA batteries. I want to add this bluetooth receiver to the speaker. The bluetooth receiver is powered off USB, but I want to keep the system battery powered.  Can I take apart the bluetooth receiver and solder the power connections to the power connections on the speaker?   The speaker is powered off 4 AAA batteries, so 6 volts.  (How many amps??) 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?

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.

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

How much power can these LEDs handle?

I'm working on a project and I would like to connect two green LEDs two ultra bright Red LEDs and 2 blue LEDs. I got the green leds from radio shack so i know they need 2.1v dc, 25ma but the red ones and blue ones I got from some old toys so I don't know what they need. Any Ideas how much power I would need if I connected them in series? I have a bunch of old wall warts of varying sizes (9v 350ma, 9v 210ma, 5v 1a, 12v 750ma 12v 150ma) but only a few LEDs so I don't want to fry them and I don't need to push them to the limts. Here's some pics of my LEDs the small one is the blue one and the other clear one is Red.

Adjustable Signal...radio, bluetooth, etc.

I am trying to figure out how to control a device that will be "off" while in the range of a transmitter (short range...under 10ft) and then turn on when it goes beyond the range of the signal. I would also like it to be an adjustable range. I was thinking the device would be "on" constantly as the transmitter tells it not to activate, but once it leaves the signal range it would activate.  Any thoughts? Thank you in advance.
