    Microcontroller project for my pool pumps

    To update I found the PDF that includes the GE contactor I mentioned in my last post. Does anyone have a telephone number for the FBI, CIA, ASA or MI6? Perhaps one of those agencies can explain why the coil resistance of contactors are available on a "Need To Know" basis ONLY!? o_O...

    Microcontroller project for my pool pumps

    Shawn, I'll echo what eKretz said. I just happened to have a honking GE (CE353A) Contactor within arms reach of me. It's a 3 pole model with the following ratings... Coil Voltage: 24VAC Contacts VAC: 240V, 480V, 600V "FL" (Full Load Inductive Amps): 30A "LR" (Locked Rotor Amps): 180A, 150A...

    Microcontroller project for my pool pumps

    Personally I wouldn't suggest measuring current to a nube. It's a better suggestion to measure the coil resistance. Power disconnected of course. You can also measure the 24VAC voltage source while the contactors are being energized to see if it drops significantly. That said it's doubtful (with...

    Stepping down speaker input to line level

    Gee Bob, I think you could have complicated this just a tad. After all if they were all this easy we'd have nothing to do here!:) Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    More powerful? Nah, I don't think so. I stumbled upon this during a Google search. It takes you to a Picaxe docs section. It's worth reading. http://www.picaxe.com/docs/baudratetolerance.pdf Chris

    Constantine, I forgot to mention that I didn't see anything obviously wrong with your last schematic. Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    Many of the members here at EP use LT Spice. You can download it here.. http://www.linear.com/designtools/software/ Though I have a copy of LT Spice I use Tina by Designsoft. There is a free version of Tina called Tina TI which can be downloaded from the Texas Instruments website...

    GPS NMEA, Failover Circuit upgrade attempt.

    I'm happy to see that you guys seem to be working out the bugs but it really has me scratching my head. 4800 baud isn't exactly the Double A Fuel Dragster of baud rates so I can't quite grasp why the default 14M2 clock rate of 4MHz is causing a problem. Keep in mind that if the default clock...

    Designing a Time Delayed Relay

    This is not a recommendation nor a endorsement. That said Horror Freight sells em cheap! You can also get a Weller brand at reasonable prices on Fleabay. On that note a high wattage Soldering Gun is useful for just about anything that requires muchas heatas. It was always my choice of tools when...

    Designing a Time Delayed Relay

    Trevor, I was going to start a new topic ("Desoldering The Easy Way") in the Resources section but it says I have insufficient privileges to post there?o_O No biggy though because It really belongs in a Tips & Tricks section that we don't have. Anyway here it is, less some photos I was going to...

    GPS NMEA, Failover Circuit upgrade attempt.

    I know the question was directed at Constantine but I read through some of it too. Page 12 is really painful to read, as it's mostly commented code shown in light green on a white background. It's an example of how not using code tags makes eye strain! BTW, Ash is doing a fine job plugging...

    PC Audio Wiring Assitance Help.

    Rich, my reminiscing caused me to forget to tell you where to get heat shrink tubing. Though I will never be the King of Reminiscence here. Hop holds that undisputed "Super Heavyweight" title. :D Anyway, you can get some on Ebay or Radio Shack (if they still sell it) and you can use your wife's...

    PC Audio Wiring Assitance Help.

    Hop is being optimistic when he said "might not fit...". I'll be a tad bolder and say it won't fit. :p It brings back a memory that's nearly 50 years old. It was my first electronics position working at a civilian owned (3rd echelon and up) military repair & refurbish depot. Most of the stuff...

    PC Audio Wiring Assitance Help.

    Molto bene but I don't see why you need to graft a length of insulated wire to it. Your photo indicates more than enough length as it is. Judging from your photo I would cut all the other conductors to near the length of the bare (GND) wire.This assumes you haven't connected any of them to the...

    Rest in Peace, Kris

    Yes, we loved Kris. Not just for his knowledge but moreover for his gentile personality that managed to be apparent even through textual communication. Kris was a true salt of the earth and definitely representative of God's finest work. Chris

    Rich, my best educated guess is that the heaver black wire that you don't seem to have is the bare wire that's integral to shielded cables that are manufactured with a foil shield instead of the braided type. Foil type shielded cable utilize a bare wire that makes contact with the foil its...

    GPS NMEA, Failover Circuit upgrade attempt.

    Ash, Look in Manual 2 - (Basic Commands). I have a suspicion that the qualifier "$GPGSA," may have to be stored in a variable or constant and then reference the variable or constant. I'm deducing this because I didn't see anything in the SerIn description that even hinted that an ASCII or any...
