    Microcontroller controlled by pushbutton for LED flashlight

    20 hours... Sorry about that. I never expected anyone to dedicate that much time to this and am feeling very guilty asking for any more help. Perhaps it is best that we all not invest any more time into it. Thank you again for all the time spent.

    Microcontroller controlled by pushbutton for LED flashlight

    I am using MPLAB X IDE v2.30. I downloaded the datasheet long ago. I made several attempts to grasp the concept of operation. The furthest I got is understanding the pinouts. Anything beyond that gives me a headache. I'm sorry, but I honestly don't have the time or capacity to learn programming...

    I also noticed that in the pinout definition in the asm file that you have GP0 assigned to transistor on/off and GP2 not used. On my PIC/circuit board, GP0 is not used and GP2 is connected to the MOSFET gate.

    MPLAB 8.63 is for 32 bit OS. All my machines have 64 bit OS running.

    The build icon is the hammer. It is greyed out and does nothing. All of the icons are greyed out.

    Microcontroller controlled by pushbutton for LED flashlight

    Thanks, what do i do with this? Load the hex file in MPLAB IPE and hit program? Anything after that? Do I need to tell the pic to "run"? Unfortunately, the code is just gibberish to me. In this version, what is the time on/time off ratio? 100 to 1?

    Glad you figured it out. I love a happy ending.

    Finding the Right Caps for a Westinghouse Monitor

    It looks like the monitor is running outside of it's native resolution, which will cause the fuzzy look. Comparing the monitor vs the laptop pictures, I would say the aspect ratio is wrong also. Compare the box just to the left of the red exit box. On the laptop it's rectangle shaped. On the...

    The smallest end mill I have ever seen is 0.1mm, so that would be about the smallest gap. There may be a smaller tool out there, but I'm not aware of it. I would guess that the thinnest track would be about 0.3mm. I would bet that anything smaller than that would break from the stress of the...

    Sounds good. Just use a 330 ohm resistor for the load/power supply. That will be a good test.

    Microcontroller controlled by pushbutton for LED flashlight

    The board is finished and populated. I didn't see any polarity markings on the cap, so I assume there isn't any. I am able to communicate with the PIC. When the PIC is powered up with the PICKIT3, there is a stray +1.5v on the MOSFET gate. I assume that is because there is no I/O's or soft...

    Microcontroller controlled by pushbutton for LED flashlight

    It took approximately 20 minutes. My spindle can only do 5K rpm, which is way too slow for a .004" engraving bit. To run this bit properly, I would need a 80K rpm spindle. To compensate, I have to really slow down the feed rate. With the right spindle it would take 1-2 minutes. Yes, this mill is...

    OK, I scaled the drawing to get the circular pads on 0.1" centers. I also adjusted the pads for the switch and Schottkey diode. I also got rid of a few things i don't need right now to reduce cutting time. I'll cut this one tomorrow.

    Yes, the PIC is SOT-23-6. I tried soldering the PIC to these pads. If it is possible, it's way beyond my soldering skills. Here's a screenshot of AutoCAD 2007 displaying the dimensions.

    Microcontroller controlled by pushbutton for LED flashlight

    Steve, I went to populate the board, and there's some problems. The Switch pads are way too far apart. There are no pads big enough for the schottkey diode. The pads for the PIC are too close together (width and length). I just noticed that the cut board dimension is 30mm x 52mm. In post 84...
