    No worries... Take your time.

    Microcontroller controlled by pushbutton for LED flashlight

    I have tried everything I have here, and I can't import those plt files with anything. I don't want to give up yet though. Can you convert to IGES?

    Microcontroller controlled by pushbutton for LED flashlight

    Here is the datasheet for the actual schottky I ordered: http://media.digikey.com/pdf/Data%20Sheets/Microsemi%20PDFs/LSM115J.pdf Could you explain (in a language that an idiot like me can understand) the effect that this reverse leakage will have on the circuit operation?

    Microcontroller controlled by pushbutton for LED flashlight

    Exactly, but I'm using a momentary push button switch, not a slider switch.

    Microcontroller controlled by pushbutton for LED flashlight

    Yes, his most recent one. It's version 3 in post #74. If the switch is pressed for less than 500 ms, the output follows the action of the switch and turns off when the switch is released (acting like a momentary switch). The output only latches on if the switch is pressed for longer than 500ms...

    Microcontroller controlled by pushbutton for LED flashlight

    Sounds good. I'll try cutting a board tomorrow. My wife makes me take the weekends off and gets really pissed if I don't. The data sheet for the switch is here: http://www.ck-components.com/14414/kmr2_8apr.pdf/. Your switch pads are correct...;)

    Microcontroller controlled by pushbutton for LED flashlight

    This electronic switch will be used in a flashlight and will be placed in series with the battery and the bulb (it is actually an LED driver, but I'll say bulb to simplify the understanding). The electronic switch will receive all of it's power "through" the bulb. When the MOSFET is turned on...

    Microcontroller controlled by pushbutton for LED flashlight

    Thank you. I have no idea what the difference would be being done in assembler or C. Take your time, no rush...

    Microcontroller controlled by pushbutton for LED flashlight

    Thanks for offering to help Adam! I have never done any kind of micro programming, so I want you to turn me into a programming guru. :) All kidding aside, it is still unknown if this circuit design will even work, so for now all I want is a bare bone program to test the design. The PIC needs to...

    Microcontroller controlled by pushbutton for LED flashlight

    Too late to edit. I meant the (+) and (-) pads.

    Microcontroller controlled by pushbutton for LED flashlight

    Just for the record: U1: SOT-23 Q1: SC59 CR: 1.6mm x 0.8mm DC: DO214BA (4.5mm x 3.3mm) DP: SOD32F (1.6mm x 1.2mm) Switch: 4.6mm x 2.8mm

    Microcontroller controlled by pushbutton for LED flashlight

    I figured out the connections. In my case, nothing will be connected to the (+) and (D-) pads.

    Microcontroller controlled by pushbutton for LED flashlight

    Thanks for the design. I'm confused about the power I/O. The board has 3 connection points. I will only have 2 to work with. There is no constant (+) available. I cannot open/import the files you attached with AutoCAD. I will try with my other CAD program when I get to the shop. A .004" cutter...

    Microcontroller controlled by pushbutton for LED flashlight

    Thanks for jumping in Steve. I was preparing to proto this with breakouts/breadboard. To answer your questions: 1) No, but I own a small machine shop and was going to cut the boards on my CNC mill. I have 1/16" FR4 here and engraving bits I believe will work. It may not work though as my spindle...

    How to interpret Mosfet RDS ON resistance?

    To convert milliohm to ohm, divide by 1000, or 3 decimal places left. Therefore, 180mΩ would be 0.18Ω

    Microcontroller controlled by pushbutton for LED flashlight

    I feared that something bad had happened to Kris and sadly found out today that he has passed away. Kris was a mentor to so many. I have all the components lined up on the bench with no clue what to do next. He was such a large part of this project that it feels wrong to continue without him. I...

    Rest in Peace, Kris

    I hadn't heard from him for quite a while and feared something like this might have happened. Very sad to hear it is true, He was a good man who was always willing to help others. I got to know him pretty well through private conversations and considered him a friend. I will miss picking his...
