    GPS NMEA, Failover Circuit upgrade attempt.

    Read up on the SerIn command in the pdf. I think it will light some bulbs in both of your wonderfully fertile young minds. :)... This IS NOT an insult. ;) Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    Uh, that would be because b28 doesn't exist. M2 parts can provide "b" variables from b0 to b27. You can see this in the Variables Window incorporated in the editor. ;) Chris

    Designing a Time Delayed Relay

    Trevor, my Fairchild 2N3904 datasheet shows EBC for the TO-92 package only. The only other pin-outs shown apply to their SMD packages. When I'm declared King of the world EBC pin-out will be one of my first decrees. :D Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    Ash, I haven't done so myself but have you read any GPS NMEA posts on the Picaxe forum? While I like to keep things here at EP there is little doubt that the Picaxe forum will have pertinent data. Chris

    I thought VisualGps was freeware. I guess not. Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    I was thinking about this issue before you posted this. I'm referring to using a single 14M2 to receive two separate satellite signals. While Picaxe states that their chips can multitask it is not a true multi-threading capability. The chip is simply capable of making use of Pause commands to...

    GPS NMEA, Failover Circuit upgrade attempt.

    I doubt very much that 4800 baud is too fast for any Picaxe. If you have any doubts why not create another program to test it? I'm referring to simply receiving the GPS into the Picaxe and outputting that data to hyperterm? Chris

    That's not exactly what the manual states. This is.... Are you certain of the baud rate used by the GPS? Chris

    Constantine, are you aware that all versions of the Picaxe editor, including yours, incorporates a virtual serial terminal to use in Simulation Mode? Chris

    GPS NMEA, Failover Circuit upgrade attempt.

    I can't answer that right now but according to the official Picaxe forum it's enabled. I do have a question though. I notice that your last schematic does not show any connection to C.5 program download pin. Does it? This pin should always have the 10K, 22K resistor configuration connected to...

    GPS NMEA, Failover Circuit upgrade attempt.

    My version does not say Beta. BTW, while reading through some of the code posted I noticed that the comments on the Pause 1 lines states "Pause for 1uS". That's actually a 1 millisecond (1mS) pause. main: 'Start 'main' program. GPS1_Read: 'Read GPSA Sentence from GPS1...

    Have you downloaded the latest PE-6 version? The current version is no longer Beta. I'm running V 6.0.8.8 Chris

    12VDC to 3.3VDC LED Metered after resistor

    It's also possible that the LED has been fried and there's nothing left but resistive impurities but if true I would expect the same voltage drop with either polarity. On that note why guess? He should test the LED + limiting resistor with 9V battery and be done with it. Chris

    PC Audio Wiring Assitance Help.

    Hi Rich, before I commit myself to an answer that may be wrong could you please post the links to where you obtained the stock photo and the pin-outs? For that matter any links to this product would be helpful. I really don't want to give you erroneous advice. I did do my own search and found...

    Bare wire is usually indicative of a shield connection which is typically connected to chassis ground. Chris EDIT: Oops! I forgot to say ...Welcome To Electronics Point!

    12VDC to 3.3VDC LED Metered after resistor

    He also said that his supply is 12V but the LED is powered by a GPIO pin. This doesn't compute either. :confused: If the uC is being powered by 12V its left this world and is destined for the recycling pile. :) Chris

    12VDC to 3.3VDC LED Metered after resistor

    This thread is an exemplary example of never judging a book by its cover. In this case it would be never judge a topic by its first post. o_O When I read that post and viewed the schematic by Stevelin9 (welcome to EP Steve) I smiled and nearly clicked my mouse to move on to the next topic. Who...

    YIPPY! We finally have code tags and I'm sure you'll both agree it's much easier to read now. :) Chris

    Thinking about opening an Electronic store: still worth it ?

    I should add http://www.mpja.com/ that is only about 1 hour round trip from me but has majority sales via the internet. I'll also openly admit that I'm addicted to Ebay's China stores with Free Shipping. The prices are irresistible! Chris
