    Yes, I thought it was a really good thread to 'watch' but died off. Martin

    buy chipless rfid tags or something similar?

    Hi jjoll, I thought I recognized your name! Cudos to you for sticking with a project. I know nothing about RFID tags except the alarm sounds when I FORGET to pay!! Also a tag is necessary for every single item. I am only responding out of curiosity. The induction loop (metal detector) didn't...

    How to connect led light with mobile headphones

    I think the resistor you are using is 10,000Ω or 10k. You need one in the hundreds, not thousands. As for not needing a meter again!!!! The way you butcher things!! You need one right now!!! Martin

    How to connect led light with mobile headphones

    Your white 5mm led has about 3.3vf What resistor are you using? Can you not buy a cheap $5 continuity meter? Martin

    How to connect led light with mobile headphones

    What? the meter or the way you are using it? What led are you using? 5mm red? If you are you need a 130 to 200Ω resistor. Or you will damage it. The 5v or 4.3v will be more than enough..Depends on the led. It looks like the red and common, blue and common are the headphone speakers. The green...

    How to connect led light with mobile headphones

    I interpreted mobile headphones as 'wireless / cordless' headphones. Do you have a multimeter to check the wires? Can you take another picture of all 3 cut ends so I can see the colours too? Did you make a note of what colour went where? Was there a usb connector on the end? Just wondering...

    How to connect led light with mobile headphones

    Blimey... This is going to be hard work. Can I ask another question before I sit down with pen and paper to work this out.? Why did you butcher your headphones like this? At least I now understand the difference between mobile and cordless headphones. So I suppose the 5volt you mentioned is...

    How to connect led light with mobile headphones

    OK, let's start from the beginning and try to understand each other. First of all YOU need to know what all the wires are that you cut. And you also need to know what you want the led to do! Do you want it on? Or to flicker? I doubt a transistor is required, but probably just a resistor. Are...

    Ribbon Cable to Stranded?

    Hi Dannicus I don't think you will find an OEM 18 pin flexi cable to two pin wire anywhere!! Cutting it and scaping it to reveal the trace might be your only option. But wait and see what other people say. Different ideas etc. Martin

    How to connect led light with mobile headphones

    You have obviously been watching many youtube videos. Try Colin's suggestion. It's not confusing at all. The led has two legs A long and shorter leg. The short leg is negative (cathode) the long er leg is the positive (anode)' Connect the cathode to a ground (common) wire and the anode to any...

    738 paradox alarm system error #2 problem

    How does your alarm work? Do you have the code numbers and what they mean? I had a Yale cordless alarm and zone 2 would always falsely trigger. Drove us mad. Until I permanently evicted the spider living inside it!! Martin

    How to connect led light with mobile headphones

    Yes, sorry Colin. I had the post open and was checking my cordless headphone voltages. By the time I replied you had already posted. Martin

    How to connect led light with mobile headphones

    I think I would have prefered the LED to come on via the power switch before I started cutting wires!! I don't there is enough current from the audio wires to even power a LED. Martin

    How to make a circuit to test ringers in rotary telephones ?

    voice module help please

    Have you checked the batteries on the modules? These Chinese modules can be very power hungry. Not all. Might be a good idea to test again with fresh new batteries. Martin EDIT.. Back to square one.. How long did they work for?

    AC Diode

    Hi Farticus, I understand the principle of your circuit which is very crude to say the least! There have been some very good questions asked above that you have not yet answered.. I would like to add to those questions. Have you actually tested your DC circuit over 400 metres? V drop...

    AC Diode

    I would imagine close to the source so he can see whether the timer is activated or the switch! Surely a neon light would solve this whole dilemma?

    AC Diode

    Again, Exactly. The left hand one is supposedly the DC version which works as he intended. Including diodes to the lamps. The right hand one is the AC version, but he can't use DC diodes for the lamps. Hence ????AC DIODE???. I am probably very wrong, but that's about all I managed to understand...

    AC Diode

    Exactly... A timer on one side and a mechanical switch on the other.
