    PIC diode tester

    I am looking to build the PIC diode tester described on the site. I would like to expand the project to test more than one diode at once.  Looking at the schematic it looks like it uses 4 outputs and 1 input from the 16F84.  Looking at the datasheet for this PIC, I could expand it to test 2...

    Radio controlled clock

    Would anyone know how to go about designing a circuit to decode the MSF signal from Rugby (UK) to create a radio controlled clock? I would like to create a project displaying date and time using the signal transmitted from Rugby. Thanks in advance

    'Op Amps for everyone'

    I thought I would post this .pdf as I think it's quite good and explains op amps really well.  It explains them right from the beginning through to complicated stuff like active filters etc... Let me know what you think! [attachment deleted by admin]

    Pb-free soldering

    I don't think that anyone has started a topic on this as far as I can see ... I was just wondering whether anyone had any experience with using lead-free solder yet? There have been various directives put forward by the European parliament, such as the RoHS (Restriction of certain Hazardous...

    Flickering dimmer switch

    I have recently installed a dimmer switch to control a circuit of 6 lights (spots) running off the mains (not low voltage lights), but when the dimmer is switched on the lights continuously flicker. It's as if the switch isn't sensitive enough. Is there anyway of adjusting the switch so that...
