RE: TST 507 REPEATER REGUIREMENT

TireMinder Manual Some info on TireMinder. I think most pressure monitors work about the same way. The monitor does not read the tire pressure all the time. Each wheel transmitter send information to the monitor at some update time. TireMinder is about 20 min.(?) between sending information. The updates from each wheel are random. If they were updating all the time the batteries would not last long. The monitor keeps track of the updates. If for some reason it does not get an update it will wait for 2 or 3 cycles before it notifies you of a lost signal. This reduces false warnings. It also means that you will not know that you lost signal for that time. Seems like all brands do the same thing. If there is a sudden change in tire pressure the monitor will send information as soon as that happens. If I remove a transmitter I will get a tire lost pressure warning at that time. It does not wait for the 20 min update time if that happens.

RE: Maxxis Load D To E - Bouncy Ride

Maxxis tire chart: clicky Ran Maxxis ST205/75R15 at 50 lbs (1820 lbs per tire) for many years. Had several tread separations but just replaced with the same type tire. Gave up on Maxxis and tried Green Ball from Direct Tire. After about one year one of them blew out and another had a large bubble. I'm sure my trailer is over weight but have not measured it. Called Maxxis engineer to talk about updating tires. He suggested going to ST225/75R15 at 55 lbs (2270lbs per tire), a 25% increase in capacity and should ride about the same. Could go to 65 lbs (2540 lbs per tire) if I want to. Had to make sure there was enough clearance for the 1.2 inch diameter larger tire and get new rims. Have not towed enough to see if these tires are more reliable. I asked about truck tires. The only thing he said was that after all the problems with car tires several years ago that they now have a much larger built in safety factor than they had back then.

RE: Solar panels for less than ideal conditions - bypass diodes?

smkettner wrote: "Example: Two 24v panels with 60 cells each (120 total cells)for a total of about 60 volts. There are 6 groups with 20 cells each. Each group produces 10 volts. (each cell produces about 1/2 volt and maybe 8 amps) If all groups are producing power you get 60 volts 8 amps 480 watts. One group is shaded you get 50 volts 8 amps 400 watts. Two groups shaded 40 volts 8 amps 320 watts. Actually it is a little less as each diode will lose 1/2 volt. So with two groups shaded it is really 39 volts 8 amps 312 watts." I agree. But, I note, as smkettner states that the total current is the current of the higher current, not the shaded cells! Also the voltage across the bypass diode of the shaded cell is about -.5V not +.5V. This could still charge if there is enough head room for the controller to work. Salvo wrote: "Taking this logic further, in a series configuration, the shaded panel t shat has 400W/m^2 irradiation will not conduct its bypass diodes. This string will have a total current about 2A, severely limiting production." Not sure that is correct. The other cells are still producing their max current. Seems that the currents will add at the junction of the shaded cells and the not shaded cells. The current from the not shaded cells will forward bias the bypass diode so the short circuit current will be that of the higher current cells.?

RE: Win 8.1 Wake-up screen

"All went well until I got to Password Policy. I have never used a password and it required me to log in with a password. If I do, does that mean I will have to log in with a password whenever I want to use the PC, or do other things with the PC?" I use a password. Every time I shut down the computer and start it up I have to enter the password. If the computer is in sleep mode when I wake it up I don't have to enter a password. It goes to the screen I was last using. I never used it without a password so don't know how to stop lock screen.

RE: Small AC motors and Inverters

BFL wrote: “I don't understand ampacity amounts for different gauge wires since they don't say (or I missed that) how long the wire is. AFAIK if the wire is shorter it can do more amps at the same gauge. “ “Thanks. I still don't understand when they say #4 is good for 100 amps if that means 3 feet of #4 or 30 feet of #4. “ I'll try to confuse you even more! Ampacity is a rating to do with heat (power). A current flowing in a wire will heat it up. The amount of heat is determined by the current squared times the resistance of the wire per unit length. If the wire is 1 foot long and has 1 Amp flowing it will reach a set temperature. (Temperature will vary depending if it is in free air or in an enclosure like conduit.) If the same size wire is 10 feet long and has the same 1 Amp flowing in it the wire will reach the same temperature along the length of the wire as the 1 foot long wire. The amount of power dissipated (heat) is the same for every unit length of wire so the length of the wire has nothing to do with how hot it gets. The total power dissipated in 10 feet will be 10 time that of 1 foot but the power per unit length is the same. The ampacity it a rating of how hot the wire is allowed to get. This is completely different than voltage drop across the wire which is a function of length and current.

RE: Win 8.1 Wake-up screen

This will affect all accounts on this PC. Must be administrator to do this. Bring up charms Select settings At bottom of screen select change pc settings On left select accounts On left select sign-in options Last item on right side "Password policy" click Change Should change to "password is not required when waking this pc from sleep" Exit screen - this should now wake up to the last screen that you used.

RE: Satellite Question

Try a new cable. Make sure connections are clean.
