    Need Some Help Finding the Right MOSFET

    Hi Dan Why could you only find a battery without protection? Batteries with protection have been qualified to be safe under most conditions. Please reconsider. What battery spec do you need. Cheers Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Update. I have the software responding to the switch presses i.e on and off. Just need to add the interupt for off in the cap charge routine. My parrents are visiting tommorow, so wont have much time this weekend. Dear Santa Can I please have a bubble with mplabx, a pizza machine, cider...

    Yes I noted that but he did say he had not set the values yet, just the layout. Thanks Adam

    Why do you need a bleed resistor? If you need a bleed resistor then place it across C2. Adam

    How can I trigger a camera from an android phone

    You maybe be better off using a comparator and rectify the audio using a Schottky diode. You will need a small capacitor after the diode, you could configure the comparator as a Schmitt trigger so there is a bit of a dead band so more defined switching can be achieved. Adam

    Hey John What's the second transformer for? The top one looks good, the only thing I can see is R2 is shorted out. Cheers Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Hop post 143 zip file is my latest code . It doesnt have any sleep function, just normal operation. I am working on some simpler code for the 302 which uses sleep mode. I can use the watchdog timer as the delay functions and change them on the fly if I want to. I am also trying to make it as...

    Creating a latch circuit with logic gates

    If they have pressed some correct switches I assume you want these reset when they press a wrong one? Adam

    Thanks Bob, good job I got 5 spares I think I just stuffed one. It thinks the port is always low, btfss PORTA, 1 doesn't work any more. :( Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Ok I assume the modes are taken care of by the LED light? In normal operation when the LED lamp turns off briefly to charge the capacitor will this not confuse the LED light and change it's mode? It was planned to be turned of every 100 ms so as far as the LED lamp is concerned it's only on for...

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Bob I don't want the PIC to reset I want to use the sleep command from the start because the way Jeff wants the button to work is the light follows the button position up until 500 ms, if I don't use sleep we would need a capacitor large enough to allow 500 ms of runtime. Then we need to...

    Duhh that's why I couldn't get it to work LOL. I must have missed it. Not used to such a basic PIC, sorry. I got the other PICs today and guess what they work :) Adam

    How a BJT Transistor works (base current version)

    All the electrons in the emitter feel an extra attractive force on them from the base region now having electrons removed from it. These have to be replaced to obey the conservation of charge. But some of the electrons from the emitter will defiantly fill these holes, they have no choice. But...

    Microcontroller controlled by pushbutton for LED flashlight

    Update: I am having a right nightmare trying to get this PIC to go to sleep and wake-up on the watch dog. With the watch dog enabled I am in a tight software loop trying to go to sleep but the watch dog keeps resetting the PIC instead of resuming the program from where it left off. I have spent...
