Pelt curing: how to preserve the ears and feet of a hare or rabbit? Answered

Yesterday got a hare from roadkill. (It is stewing right now). I want to try to do an attempt at taxidermy. I got the pelt off intact, except the lower part of the legs, and I still have to do the head. I was thinking of just letting the legs dry: Quite tedious to take the skin off, and hardly any meat on it. Can I do this, and can I just let the ears dry?

Why do the L and R speakers of headphones sound different depending on which ear they are placed in?

If I take the right headphone speaker and play it in each of my ears, the sound doesn't sound the same in each ear.

How to get In-ear headphones from slipping out.? Answered

I have a pair of Skullcandy headphones. They used to stay in my ears when pulled on, and just when wearing them. Now they always fall out. When I'm sitting or standing up, All the time. When I Absolutely needed to use them I would wear some kind of stretchy, over the ears hat. But I don't like wearing the hats all the time. Is there a way I can fix this without getting some new tips?

Where would I find ear peices similar to the ones on the provided link?

At my church, we use hearing devices to help some older people hear better. A lot of the ear pieces have broken because the little piece of plastic that holds it to the ear has broken off. The ones we have are the same as the ones in the link, but I can't find any for a cheap price. The dealer I have talked to says he can get them for me for $9, but I was wondering if there were any cheaper ones out there. It is just a standard 8th inch plug. Thanks.

Best sub $20 in ear headphones with GREAT bass? Answered

Looking for some headphones to replace my Skullcandy buds that broke... I want something with great bass- something that really punches. Preferably with inline volume control- I am using an ipod touch (really love the volume control). I have a pretty small budget, around $20 is my goal, but as I am not an audiophile, they don't need to be perfect :) Just in ear headphones with great bass.

Any ideas on an in-ear white noise device to help stutterers/stammerers?

Hi, This is my first post. I don't know much about this kind of tech but am eager to learn.  I want to build a hidden/discrete wireless earpiece which can play a short burst of white noise (1-2 seconds) when a button is pressed (see below for an explanation of why on earth I want to do this). The button would need to be able to trigger the white noise from a range of around 1 metre so that the controller can be kept in my trouser pocket. There are earpieces around which play white noise (to help people sleep in noisy environments) but I want to be able to control whether or not the white noise is playing. I thought about using a wireless earpiece (e.g.) with bluetooth, however it seems like the maximum range for this would be around 40cm. Anyone know of alternatives?  WHY WOULD I WANT TO?! Individuals who stutter/stammer often experience blocks. It's not that you'll hear them repeating sounds or anything - their speech just totally freezes up. For reasons which aren't entirely clear, listening to white noise can help stutters who block to start talking. White noise can be played before trying to speak, disrupting our auditory feedback - resulting in less blocks. Some devices have made use of this, e.g. Edinburgh Masker (, but were ugly, bulky and didn't allow you to manually control when the white noise was playing. Other devices, like SpeechEasy make use of Delayed Auditory Feedback ( - which can help some people but is of no use if you aren't already making some kind of noise. Is this impossible?  Many thanks for anyone with ideas on this! Cheers Oli

240V Power Socket with USB outlets leaks current/not grounded ?

I just got a 3 pin wall power socket (240volts/EU style) that comes 2 built in USB charging ports. I replaced my wall power socket with it and both the USB charging ports works fine and so does the power socket (when I connected my 240volt desk lamp to it). However, when I happened to make a call on my iPhone whilst it was charging (from one of the usb ports), there was a "tingling" sensation when I held the phone to my ear.  This is a repeatable process... turn the switch off/disconnect from the USB port and the "tingling" goes away, turn it on/connect the phone to the USB port and the "tingling" is back again. There is obviously a grounding/current leakeage problem from this "Socket".  I can't feel the "tingling" when the connected phone is being held in my hand. It is very apparent when the phone is held next to my ear.   I have ascertained that the connection to the power socket is correct ie.  Live, Neutral and Earth are all correctly wired. QUESTIONS: 1.  Is there a way to detect this leakage other than only using my ear ?  ( I need to show the manufacturer that this is a real problem either with a video or be able to measure this leakage objectively).  Is there a electrical device /detector for this ? 2.  How dangerous is this situation ... Could it have electrocuted my family ? 3.  What is the cause of this ?  Is it because of poor earthing/grounding in my house wiring ?

Credit card crystal radio

What do you think about the feasibility of a credit card sized crystal radio? (Fits inside a wallet) Some possible i though so far are... A simple pcb with a diode, and a capacitor and a coil wrapped(protected by duct tape) around it. The antenna has to be tied to a hole on a corner. Or it is coiled to the card, ready to be unwrapped. The ear piece can either be external... Or can be glued to the card itself, but you must put the card near you ear... Instead of a winded coil, maybe it can be part of the pcb design itself... and to tune it, you unhook a beady wire and place it in the holes placed in a interval. What do you think? Any more ideas? In fact. a competition can be made for this idea.

how do you get from Ampere to Ampere hours? Answered

I know, basically it's not too diffy. I checked wikipedia and in the end i get to Coulomb, but the information i need is: i wanna build these cat-ears: and as material one needs a LiPo battery - the guy says "anything that will be able to supply 3A worth of current" and links to a 800mAh-battery at hobbyking. I first bought a battery with 4000mAh, say a battery that gives 4A per hour, but the one i got is quite heavy and i doubt that it's a good idea to use it in this light-weighted project - so how the hell did that guy get from a 800mAH-battery to the 3A worth of current? How do i calculate this way?

Mag-safe type Audio Connector for Headphones?

Would it be possible to make a Magsafe-like cable for headphones? I'm always either editing video or listening to music while on the desktop in my family's living room. In order to not disturb everyone, I use headphones. But getting up time after time is very much a pain when I have to pull my headphones off, set them down, then head off to wherever in the house I need to go. (Kitchen, toilet, etc...) I think I've come up with a solution that would make things a lot easier. The end of the heaphone cable is normal. Standard 3.5mm. But the other end, which is usually hidden away in the left ear cup all stripped and leading to different speakers, is seperated from the ear cup, and connects and stays on with magnets! The only problem is that I'm not quite sure what to do to make this...anyone have any ideas?
