    555 monostable on power delay

    Also.... Simulation or not it is good engineering practice. (pin 5 )put a 0.01 microfarad capacitor to prevent fluctuation of your RC network. Monostable or also called one shot. The capacitor on pin 5 will guarantee your output current pulse when you press the button manually or as you put...

    is it possible to build wireless tags

    Welcome to Maker Pro. Not should we Maker Pro. Maybe Maker Pro. We should "Make Her Pro" So on and so forth. And yes sometimes we must nudge gently as to what the TS is actually thinking about. Gently is a relative term I'm rather heavy-handed.

    Everyone's entitled to their opinion. You sure you got the right thread? "You see the red circles" Blah blah blah blah blah. They all look pretty bad The TS tested zener. It is labeled on the PCB silk screen as ZD1. I'll give you a hint at this location it's circled in red! Where's Waldo?

    How can I make a switch actuated by a signal

    Also.... You can maybe use your power locks,I don't know you're set up, type of vehicle, modification, you may or may not have made. The photos below show fuse taps you figure out which fuse belongs to your vehicle's power locks or (anything else for that matter) install these fuse taps so when...

    How can I make a switch actuated by a signal

    This is only an idea but a remote operated trunk release switch so only you can open the trunk a couple feet from your vehicle or meters. I'm sure you can find something similar for your particular vehicle. if you have a trunk light that could be used as a power source and you can have your own...

    Parkside PLG 20 A1 4.5A Battery Charger fix

    The schematic below is switch mode power supply from another thread. Because of your responses I believe this paints a picture for you that needs no explanation. But notice on the secondary side the 12 volt 2 amp output and scroll down to that led That is your opto coupler or could be, if we're...

    Fire alarm using a PTC as a sensor.

    Poppycock I got flames shooting out of my head. Heat alarms (detectors) respond to high temperatures of 135°F (57°C), not smoke or fire, and are ideal . They are another useful part of any fire safety plan. Smoke alarms are not designed for use, in most areas & depends on application. Many heat...
