I thought the first thread was hilarious, so here goes another post.  Some more background information on what has happened to my poor batteries.    One year, I left the batteries in the garage.  The garage is Unheated.   They were left in their places that they needed to be.  One in the riding lawnmower (what a lux) and one in each motorcycle.  The battery in the  riding lawnmower was about 3-4 years old, and one of the cycle batteries  was new, and one was around 5 years old.  Upon spring time, I discovered that all of the batteries were dead, and needed to be recharged.  They all worked properly, except for the older ones, and they had to be replaced  about halfway through the summer.  (they had originally been stored in the garage, and I think I remember my dad charging them in spring)   Last year, I decided to bring them in to the basement, which has two parts. one is dirt and brick, and the other is concrete.  I brought in all three, and discovered in the spring, (about 15 days ago) that not only were the batteries dead, but when I put the charger on them, the charger said "HMMMMMMMM" and  the amp-meter read around 1,000,000,000  (In other words, it was pinned) the internal circut tripped, and I went on to the other batteries.  They were the same.      Realizing that we still had 2 GIGANTIC sailboat batteries, also lead acid, I decided to put the charger on them.  (these had been sitting for around 1 and a half years, on the brick and dirt part) and noticed that they only needed a small charge, around 2 hours or so on trickle.  I tested them by using them at the local gas station for giving jump starts, and they worked fine for around 25 of 'em.    This leads me to believe one of several things.      1) I bought really #$%tty batteries last year. (sorta true)      2) the concrete has something to do with the discharge of the         batteries.      3) There was enough moisture to short out the terminals in the            room where the concrete is,       4) The dirt room was able to absorb the moisture in the air          better than concrete.  (BTW, I can almost waterski in the dirt room)

With relays alone, you will always get a transient when you abruptly turn ON or OFF any channel.  If you don't want to hear the transient, use some other device (a photoresistor-output optoisolator is the usual sort of thing) to gently MUTE the signal, then switch, THEN remove the power from the lamp in the optoisolator.  	It used to be standard practice to employ photoresistors in switching audio, because the photoresistor time delay (a few thousandths of a second) kept any noise in the digital side (which drives the lamp) from contaminating the audio.  And, the devices are cheaper than relays.

Uh, Bob, why is the battery warmer than ground temperature?  On the time scales in question, and with the considerably reduced temperature swings several feet underground, there isn't going to be any major temperature difference between the battery and what it's sitting on.  >... Question - why does a concrete floor feel cooler than the  >surrounding dirt when you place your hand on it?  Because the temperature of your hand, *unlike that of the battery*, is determined by the balance between internal heat production and external heat loss.  You're feeling the greater rate of heat loss from an object (your hand) which is kept much warmer than its surroundings.  In the case of an object with no significant internal heat production, this will affect how quickly it comes into equilibrium with its surroundings (if it started out not in equilibrium with them) but won't affect the final temperature.  For the same reason, windchill affects whether you will freeze but not whether water will freeze.
I'm looking for a circuit that will flash an led on in response  to the output from a walkman cassette player. How could I do this? I don't want it just to turn on, I want it to 'strobe' once so to speak, per every beep I put on a cassette tape.        Would it be better to use a circuit based on the volume of the beeps on the cassette, or better for the leds to respond to a tone of a certain frequency? Is there any easy way to do either of these? I'm looking for  the simplest circuit possible. I guess what I'm asking for is some sort of color organ, but not quite. Let me trt to explain again...        I'm going to have a pattern of beats (or beeps) on a cassette tape. So on the tape you'd hear:   beep! (pause) beep! (pause) beep! (pause)..etc.  , with speed increasing as time goes on. I want to synchronize an LED ( probably two of them) with the beeps on the cassette tape. So the LED, with each beep, would go on and off real quick, generating a strobe light sort of effect. The rapidity of the beeps on the tape would in turn effect the rapidity of the blinking of the LEDS. And if there was no sound on the tape (except for background his), the LEDs would remain off. Please help!     Thanks,

If the set is direct line powered, try checking the [likely to be there] hybrid regulator module down stream from the 170 volt supply.  Several sets I've looked at use a 135 volt regulator.  The regulators have a tendency to short out, making the safety circuits shut down the EHT supply section.  Try putting the set on a Variac or adjustable transformer and lower the AC input voltage to the set to about 90 volts.  If the set operates nromally, then you know you've got a shorted regulator.  There are myriad other areas for problems, but I've seen the one above several times.  Also, if the set uses one, the trippler module may be shot; that's fairly common.

The ground is supposed to be a protective ground, and though what you suggest looks good on paper, it's dangerous to rely on the same wire for power and protection.

I've seen several references to split- or separate-beam radars, which I claimed didn't exist.  Gotta eat some crow here - I wasn't aware of them. All I really knew was that it can be done with one beam.  I believe the rest of what I said is accurate, though.

My impression -- it's not an area I've played with much -- is that the much-beloved NE567 is basically obsolete.  If you want to detect a 1kHz tone, set a switched-capacitor filter chip to that frequency, feed your input to it, and see if anything comes out the other end.  The NE567 was what you used when good clean bandpass filters were hard to do; nowadays they're easy, and the results are better.

What frequency is used for >the land-based beacons?  >Thanks in advance,  >Charlie Thompson >.  Here's a rough sketch of how the system works.  A reference station with a very exactly known position computes the errors in the incoming GPS signals.  These errors are due to several factors including atmospheric distortion, SA (Selective Availability) time dithering, etc.  The reference unit contains complex computational  equipment to "back out" the errors in its position (since it knows where it is already).  It then transmits these corrections on a  broadcast which is available to any number of relatively local receivers.  If the receivers are nearby (<300km) and are using the same satellites as the reference unit, the errors should be very similar for the reference unit and the receiver unit.  Thus, the receiver unit may apply the corrections calculated by the reference unit.  The US Coast Guard is currently (as far as I know) installing a series of coastline transmitters for differential GPS.  These stations will use existing radio towers.  I believe the frequency is to be approximately 305 kHz.  There are many other private corporations offering DGPS signals on different frequencies.  For example, PinPoint ((310)-618-7076) offers correction signals and receiver units using an FM broadcast system which has stations all across the US.  The correction codes are usually transmitted using the RTCM 104 format. Advertised accuracies espouse 1 to 5 meter errors.   ------------------------------------------------------------------------- John P. Baker                   | My opinions are my own.
