    matched impedance question

    Update on the magnet test.... The dead lights in the freezers turned on!!!! Ok! I will test the volts tomorrow, but the alarm is still bonging!

    matched impedance question

    So what you are saying is that the proper impedance is likely to cause more problems than the clip is worth!! Got it! So if the signal is supposed to be 0(zero) when the door is closed the switch is maybe bad so check the switches. Now I have to take all four doors off... Where is your...

    matched impedance question

    If I have a board that has a pinout for a reed switch that diagnostics about 5 volts into/or stops from/ going into the circuit to make an alarm bell sound when its high... ipqr- a door switch that says when the doors open.... The board is getting a 4.88v reading and the doors are closed and...

    problem with the table saw motor. Please help!

    really great ideas..! Pull the cover off the end thats sparking and you will see there are plenty of little parts to lose in the dirt near your feet. All of them are important and necessary for the thing to work right. I just thought I might throw in, it will|is working other than the...

    I need a Maker

    The problem with recording is that the microphone has to be deep enough to resonate sound(you can cheat and math it to death). Thats a rough 6mm deep lie.. that means your mic will have to sit laterally in your 22mm hole. You can make a 2mm doped disk with the circuit on it, but I think after...

    battery pack question

    Thats why I hooked it up backwards!!! (didn't mean too.) OK = POLR (my friend answers in the crowd).... "unless its ground" I waited a second and quietly said... POLR only there is no bridge. They all claimed there was a such thing as POLAR... and I said "tap it and see if it is source or...

    8 and 6 ohm speakers

    Does anyone know what the R788 on the small speaker means?

    8 and 6 ohm speakers

    sometimes you are measured as impedance also...;)

    HEMCO USA SD3 201-10101

    You guys know me so don't take any of this seriously k?? I think what you have there is a 70's invention we called a super tweeter. It can be used for all kinds of stuff, from making a squeaky door noise to dumping high frequencys into bells so they don't reverberate.... anyway, it was our...

    battery pack question

    Back in the day,they always charged in stacks of multiple batteries, they always put a known bad one in as a "dud". I called that one my omega strain! Of course my Andromeda strain was the power I drove the micro circuit with.

    battery pack question

    Thanks for bringing it all back to me. I really appreciate that. The original rechargeables we're designed to be integrated. The actual material wasn't ni-cad, but the raw natural ingredients were the ideal solution mathematically. The ideal circuit failed horribly, so they (big money, no...

    8 and 6 ohm speakers

    The 12Axxxx set was in a console I stripped, there is a subwoofer from another pair that was 8 ohm. I strapped a few resistors to the lines to level the output by meter. The meter reads 8 ohms at the speakers connection to the amp. It was quite a chore getting it right, I had to use a 4 ohm...

    Samsung SmartKegger

    The system wiring diagram in the 40.00 service manual is similar too, but not exactly, as the wiring in the device. I finally found the reed switches the freezer doors use, and they are in the hinge compartment on the doors. You have to remove all the doors to access the 2 reed switches in the...

    Fridge compressor test....

    So assuming the PBA is bad...(main board error) there should be errors on the self diagnostics display. There are no errors displayed.

    Fridge compressor test....

    Problem again.... The board has pinouts to check voltages on, but the wiring is missing...the one it's missing on is ok. The other out is on, and should be off it's making the door alarm sound constantly.

    8 and 6 ohm speakers

    7 channel two pair sets of fronts, one pair of rear, one center, but I don't think you can use both fronts at the same time. So it's probably 440w/6 watt per channel. Multiple input tv, vcr 1 and 2, tape 1 and 2.. line input, tuner it's a pioneer, vsx-5700s No cd or dvd. .too old!

    8 and 6 ohm speakers

    I built the speakers using what ever I needed to make them 8 ohms from 6 ohms. Most of the speakers in the cabinet I made, were 6 ohms from an old 1950's console stereo.. What I was looking for was a good conversion formula to use for ohm/watt stereos. Watts Per channel or total watts, I...

    8 and 6 ohm speakers

    I have a really big 480w pioneer amp that has settings for 6 or 8 ohm speakers. So I got these speaker cabs and used some 6 ohm speakers from an old console to make a set. I used what ever I needed to, bringing the ohmage up to match my 8 ohm amp. Anyway they worked but were very quiet. Is...

    battery pack question

    The pic is the sub-C that are in the pack. They are Ni-Cd Liang Ye SC1300mah 1.2v. I took a 15 pack from a different device but the same configuration, that didn't charge. I tried it in my current but it didn't work either, so I have chopped the packs up into sets of 2. I am charging them in...
