    Wiring in Recaro seats, need guidance from experts

    Thank you I'm in the process of executing that at this very moment. Good luck, Chris

    Ed, you never cease to amaze me! Micheal, I'm going to leave you in good hands? Cheers, Chris

    Transformers In Parallel

    Damn! I love your "Git er done" hammer and hole in the finger attitude! Yes you can parallel transformers but they must be in phase with each other. The other issue is if the output voltage of each transformer are not exactly the same the higher voltage transformer will back feed into the lower...

    LCD power supply board

    The schematics you posted are only partial. So from what you posted I would venture a wild guess and say those Zener Diodes. Chris

    Wiring in Recaro seats, need guidance from experts

    Hello Michael, I sent Ed an alert. With any luck he's as photo sharp as he always is. BTW, I always welcome nubes to EP but I now see I was remiss. Soooo..... Welcome To Electronics Point! Chris

    Wiring in Recaro seats, need guidance from experts

    This is my personal opinion but I think our premier photo decipher guy is ED. He's a retired (I think) NASA engineer. Let's see if I can drag him over here. If he responds you can't miss him. His avatar is a photo of him in his white NASA smock. His avatar says "NASA", so you can't miss him. I...

    Connector and Cable advice

    Mil spec is definitely robust but what is your application? That said, solder terminals (if your proficient) is the best way to go. Chris

    How to control the field current of an alternator by using PWM?

    Good luck with your project but as an avid cyclist I pray to God that I never reach a point that I can appreciate, or even comprehend a bike that goes absolutely nowhere. I absolutely despise those lame Peleton commercials! Chris

    Turn on device when car speaker signal detected

    Thanks, that's what i wanted to know. . Chris

    Turn on device when car speaker signal detected

    If you exclude the cap and diode the output will be switching ON - OFF in sync with the audio. D1, C1 form a rectifier and filter. Though the output of the bridged amp never goes negative (with respect to GND) it will provide a discharge path for C1 if D1 is excluded. If your OFF delay is too...

    Correct name for push button switch

    You're describing a DPDT (PB) switch. Like this..... Chris

    Over-voltage protection for op amp

    Adam, if every request on EP could be resolved with a single resistor there wouldn't be much point in keeping EP up and running. There must be some scrap electronics you could cannibalize for a single common Diode? Chris

    Circuit that sends 1 pulse when input goes high, 2 pulses when input goes low

    Been there. Done that. Didn't like ASM. I'm a VB6 programmer and Great Cow Basic's syntax and structure was easy for me to transition to. There is no Bootloader involved with GCB. It programs blank PICs. The GCB editor can mix and match Basic and ASM seamlessly. I'm happy as a clam with it! Chris

    Trigger a relay when plug is present in outlet.

    Like I said I always return from the watering hole a whole lot smarter. What I was going to propose was a 12V low current sensing circuit that would conduct when an appliance was plugged into the receptacle. This current was going to control a Changeover relay that would disconnect the sensing...

    Trigger a relay when plug is present in outlet.

    I do have another idea that would be more elegant but definitely more complex. I'm heading out to my watering hole where I'll mull this over and sketch circuits on bar napkins. When I return home I'm usually much smarter!:D Cheers! Chris

    Circuit that sends 1 pulse when input goes high, 2 pulses when input goes low

    Hop, after reading your reply in post 20 can I assume that while the output will be OR'd to a single node the input is not being sensed at a single input node? I interpreted the first post as single pin input, single pin output. Chris

    Circuit that sends 1 pulse when input goes high, 2 pulses when input goes low

    Hop, I hope you do because I can't bring myself to mess with multiple 555's and or a 4017 when I know I can do it with a single uC and a 12V output level interface. Besides that, he's worked with 555's before. So I'm sure he'd like to design it himself, with just guidance in the right direction...

    Could defeating LIDAR speed detection be THIS easy ?

    The only thing (and this is really unlikely) that resonating the tag could possibly do is slightly modulate the LIDAR carrier. BTW....Since you're so certain that it must target the tags please explain how they're doing that when we don't have front tags in Florida. maybe my Grandson knows. He's...

    Circuit that sends 1 pulse when input goes high, 2 pulses when input goes low

    Thanks for the details but we still need an answer to #2. Chris

    Good question. Maybe this is why? Chris
