    Phase shift

    Here you go. Waveform 120 degrees apart. Thanks Adam

    Phase shift

    Yes but do you want the new wave to be in front or behind the input? Google lead and lag phase shift for examples of what I mean. Adam

    Phase shift

    Which way do you want the phase shift lead or lag? Adam

    Trying to solve exercise in art of electronics involving transistors and diodes

    LOL Yeah I had to turn my head 90 degrees, if anyone had seen me they would have said "look at that poor chap with his head on his side, I suspect he was born like it". Adam

    Request RFID module name

    Hello. Your best bet really is to search Google, this is a research thread IMO so we would have to do the same as you. Why no try and search for RFID chip or RFID IC? Thanks Adam

    Protection circuit for Li-ion batteries

    Yes I would go along with that. I think what we should do is warn the OP of this, dont you think? Adam

    Protection circuit for Li-ion batteries

    For higher voltage packs I would agree. Anything larger than 24 Volts it would be best to balance or increase cut off voltage level. But two cells are going to be within 2.5% of each other as far as capacity goes. Making sure the batteries are from the same batch and manufacture is paramount. Or...

    Adjustable Schmitt Trigger Circuit Help

    It's probably a stupid question but the waveform the OP supplied appears to be showing a +/- swing. Is this correct, or is he using a half supply common? Adam

    Protection circuit for Li-ion batteries

    What regulator are you using BTW, this could also be playing a part in this? Adam

    Protection circuit for Li-ion batteries

    Run what at a lower voltage? If you mean the load then yes it should help because the load should draw less current. Adam

    Protection circuit for Li-ion batteries

    Just a lucky guess ;)

    Giant newbie, needs help regarding transmitter

    You have to remember that if this all goes wrong because of the advice we gave you due to lack of information on your part. Who are you going to blame? Why don't you Google small RF transmitters. Adam

    Protection circuit for Li-ion batteries

    Give that a go across the supply. Close to the load. Adam

    Protection circuit for Li-ion batteries

    Exactly, I was just going so mention that. You may need to add some large capacitors to support the supply rail. Do you have any? Another option would be to use a logic level MOSFET. Adam

    Protection circuit for Li-ion batteries

    What do you mean around the charge? -1.5 Volts? you don't have a negative supply, how are you getting this? Where are you measuring? With a suitable heat sink the current transistor can provide 800 mA with the correct base current. Adam
