    Cordovox piano G keys dead

    Yes, what I was thinking was the circuit between the octaves and the keys, in the (sol) or G note circuit may be failed cause all the G is the only thing that really wrong, it has tuners to correct the intonation... Great idea!

    First remove 2 extreme corner screws to remove woodgrain cover. Boards are under keys accessed by removing two(2) screws on the bottom on the piano and lifting keys on hingesin front of the tone wiring harness... Holy moses.... Full implementation on each key, that's 68 circuits...

    Cordovox piano G keys dead

    Got this farfisa style electronic piano... It has an intonation problem in the c-c#d-d#-e section, and no g's will play. It is a pp23 unit, Italian piano, from the famous accordion maker. I bought the schematic and will attempt a fix... Does anyone know anything about these??

    I got a ricoh wide format duplicator that had a issue without starting, so I called the number on the machine. There were some Pakistani or something on the line whose accent so hard to understand I felt put out and they connected me to a manager who wasn't much better. I need you to know this...

    Speaker output ohmage without information.

    There is a gleaned 40 hz signal there (skuttlebutt gleaning tech info) Does that help? About 20ohm guess?

    Speaker output ohmage without information.

    What is the standard loudspeaker ohmage?

    Speaker output ohmage without information.

    That means the speaker terminals on the device do not amplify the signal, and it requires a set of speakers that maintain their own power, and amp. It would seem to me, that output, would be considered line voltage, and I don't know what the line voltage is on an output for a set of terminals...

    Vidikron Crystal One

    The user guide, I got from the guys shows a different input output also. I think one might attribute this to a second version, or a new style they made when the first generation sold successfully. I am looking for the original paperwork and a source of lamps for it!!

    Speaker output ohmage without information.

    Is there a meter test I can perform on the speaker output terminals of a device, to get the ohmage they are supposed to support??

    Vidikron crystal one ifr eye codes

    Is there a good way to breakout the remote control codes from a device that doesn't have the original remote? What kind of Arduino set would be required to make my own controller... I am imagining a conference projector built-in to a podium with the remote controls for the projector built into...

    Triggering a passive infrared sensor?

    Pardon... Duh, passive systems are usually triggered by the ground circuit,or fault. rather than the power circuit. That being said, all these sensors must be powered, for them to work, and usually they are not triggered at all but always on. That means you can't hack them. I always look for...

    Vidikron crystal one ifr eye codes

    This lens is big. Close to 5 " in diameter. Back in the days of the 90's there was one in every business for meetings to replace the chalk board. They were often built in to conference rooms as a podium. It projects a 4x3 , TV size image, from what I am gleaning... 200cm, but most had a...
