    Turntable Spinning Fast in Reverse

    Glad you sorted it. Don't forget to adjust the motor pots as you have already adjusted them!!:) Martin

    Turntable Spinning Fast in Reverse

    Hmm, not sure about that. Wouldn't the motor have a 'stator' built in for DC? The turntable power requirements are DC not AC.. Am I missing something here? Martin

    Turntable Spinning Fast in Reverse

    Great, the output of the adapter is 12v DC. So, you have 12v coming in and the motor spins backwards. The only possible cause it you have wired it backwards... IMHO. I would swap them around. Martin

    Turntable Spinning Fast in Reverse

    Great, while youre online, can you post a pic of the power supplies label? Have you soldered the wires in exactly the same place as the old wires were? My motor wires go to the small board top left corner.. Have you got a multimeter? Very unusual to have a blue as positive and red as negative...

    Turntable Spinning Fast in Reverse

    What would we do without Google? Incidently, could the OP clarify exactly where he connected his wires inside? My thoughts are that 'orange and blue' wires seem more like motor colours. Did you connect the 12v direct to the motor? Martin

    It looks like 'Q' has been working on your idea already....

    Remote Controlled Ski

    Hi Nathan, this sounds like a fascinating project.. But your images didn't load.:( Personally, I don't think the servo idea will work. It would have to be very large for the torque you are talking about. (I could be wrong). I think this is a job for 'Q'. You may be better off thinking about a...

    Can someone ID this Transistor ? Offer Equivalent part ?

    Nice find. I only referenced from the service manual.

    Linear Combination OP Amp Design

    I don't think you have been banging hard enough.... Have a little catch up here All jokes aside. I feel your pain. May be this should have been posted in the Homework section. Martin

    Can someone ID this Transistor ? Offer Equivalent part ?

    AH OK, sorry, I thought they might be equivalents but depended on whether NPN or PNP. Martin

    One Way Communication from Chip-to-Chip

    OK, thank you. Martin

    One Way Communication from Chip-to-Chip

    Yes, I get that. Is there any distance between the two IC's? The single wire between the two IC's is how long? Martin

    Can someone ID this Transistor ? Offer Equivalent part ?

    davenn might have posted the equivalent components for you.. Which is why I 'quoted' his post. But his quote is a NPN or PNP. Check here Martin

    One Way Communication from Chip-to-Chip

    I realize this is a very strange question but: First you wanted to control relays...... Now you show leds..... Is there a distance between these two IC's with one wire communication? Hmm Martin

    Akai plasma 60" picture looks like a lava lamp sound still good

    I very much doubt it. I think your rear panel is plastic. Can you give us the model number of the TV? Which board had the blown fuse? Can you upload a clear and close picture of the board? Have you got a multimeter? Martin

    Basic electronics

    Hi Anders Lund. The answer is YES. But safely NO. And I believe you would be foolish to try your idea!!

    Not getting the ideal 555 output

    So small then?:eek:
  20. Martaine2005

    Could use some experts insight into identifying connector type.

    Hi Adam, I know you don't like the 555, but c'mon. post #3 supercedes yours..:D
