RE: MD: NiMH batteries in a NiCd charger?
There's only one reason why you need a different charger for NiMH ... peak detection. See, in an automatic fast charger, you need to know when the battery is full. The charging process is still the same ... DC straight into the battery. But the peak (otherwise known as Delta-V) characteristic is different between the 2 chemistries. So what does this mean? Throw a NiMH battery into an automatic NiCd fast charger and it won't know when to stop, and there go your batteries. So as a general rule, don't do it. The only exception to the rule is if you're using a non-automatic slow (i.e. 14-16hr/overnight) charger.

Can I charge NiMH AA/AAA batteries in a NiCd charger? I thinking of "upgrading" my NiCd's (which are getting old) to NiMH to power my MD players and a Handspring Visor. If I need a different charger, what are the recommendations for NiMH (and, preferably, NiCd) chargers capable of charging AA and AAA batteries? Thanx! __ Do You Yahoo!? Yahoo!

Re: MD: playback only in left ear (was MD question)
hey, thanks for your help, it seems that the cable i am recording with only has one of those black bands. my next question is... how do i get the music from the left ear phone to play in both earphones. thanks, WiLL - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
MD: Plug-in power explained...
Consumer MD recorders are designed to be used with electret capacitor microphones. This type of mic uses a small foil diaphram with an electret (permanently charged) backing. This, like all capacitor microphones, has a very high output impedance, so it cannot directly drive the connecting cable. Included in the microphone capsule is a Field Effect Transistor, and the high impedance gate of the FET is a perfect match for the microphone element. A small voltage, generally 1.5 to 10V must be supplied to operate the FET. The drain current of the FET is propertional to the gate voltage, and the FET is able to drive a much lower impedance, so the high-frequency roll-off caused by the cable capacitance is negligable for normal cable of up to 100 ft. or more. Plug-in powered microphones have an unbalanced 2-wire output; stereo mics have a 3-wire output, 2 hot wires and a ground. The recorder supplies a small voltage, generally 1.5 - 2 volts DC, between each hot wire and ground, through a 2k (approximately) resistor. Phantom powered microphones have a balanced 3-wire output; stereo mics have a 5-wire output with a common ground. The mixer or recorder supplies a higher voltage, often 48 volts DC but some mics will work with as low as 9 volts, between each signal wire and ground, through matched 6.8k resistor pairs. The differences between plug-in and phantom power are: 1) Plug-in is unbalanced (ground is used as the return of the audio circuit), phantom is balanced (has individual hot, return and ground). 2) Plug-in supplies the power voltage hot = +, return/ground = -. Phantom supplies the power voltage hot and return = +, ground = -. 3) Plug-in supplies low voltage, generally 1.5 - 2 volts, whereas phantom supplies a higher voltage, often 48 volts. Plug-in and phantom power are incompatible. Plug-in is unbalanced; phatom MUST be balanced, since not only the hot but the return must carry the power voltage. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
Re: MD: playback only in left ear
Will followed up, | hey, thanks for your help, You're welcome. |it seems that the cable i am recording with only has one of those black | bands. So it's a mono cable. Get a stereo cable to use instead. | my next question is... how do i get the music from the left ear phone | to play in both earphones. You normally wouldn't want to, since it's only half of the music, but you could do it with a bookcassette adaptor. It's a splitter that looks like a headphone cable Y-adaptor, but it routes the left channel of the plug to both channels of one jack and the right channel of the plug to both channels of the other jack (instead of doing left to both lefts and right to both rights like a headphone cable Y-adaptor). - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
RE: MD: Christmas Present Gloat: BO earphones
The model is A8 - I was lucky enough to get a pair of these from my wife for Christmas. They sound fantastic connected to my Aiwa AM-F70 on my walk to work each morning. :) Regards, Grant -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of tenebrion Sent: Friday, December 29, 2000 11:30 AM To: [EMAIL PROTECTED] Subject: MD: Christmas Present Gloat: BO earphones Someone recently was enquiring about high quality earbuds. Take a look at Bang Olufsen's latest offering - they don't actually have a model name or number, but as they seem to be the only model, they're quite easy to identify. As you might expect from BO, the design is extraordinary. Made from aluminium and hard rubber, they consist of an over the ear section, like part of a pair of spectacles, connected to an adjustable metal rod which sits in front of the ear. This holds the earbud itself, which in turn is articulated in such a way that it can press into the ear for maximum bass response. Hard to describe, but think Borg implants and you'll get the general impression. More importantly, they sound awesome, and have easily supplanted my old pair of Aiwa VX50's, which were the only earbuds which in their time merited comparison with over the ear models. Visit www.bang-olufsen.com and look under accessories for a closer look. The site is a masterpiece of design, but very flash intensive, so you need a fast connection. Having said that, I suppose to habitual BO purchasers, that's a given. I don't know how much the little beauties cost, but as they were the main present from my significant other - I hope it was a great deal!
