    Microcontroller controlled by pushbutton for LED flashlight

    This would be just one of the drivers that would be used. As far as I know, there are no datasheets available for any of them. The switch would need to work with incandescent also, but that would be the simplest to build around. Dominant battery choices are single Li-Ion and IMR cells.

    You just may have a very simple elegant solution there...

    Microcontroller controlled by pushbutton for LED flashlight

    Most of these LED drivers perform mode changes during brief "off" periods. I have no idea how much off time is needed to change modes.

    Microcontroller controlled by pushbutton for LED flashlight

    I would have included that info if I had thought of it. The switch will be used in high powered LED flashlights, mounted in the tail end. The board can only be populated on one side. The other side will have a spring that will be the (-) battery contact. Several different LED drivers will be...

    Kris, do you ever sleep? Isn't it like 5am over there?

    Microcontroller controlled by pushbutton for LED flashlight

    Oh boy, you guys are going to hate me... I was just sitting here thinking that this switch was too simple to be true, and it is. One thing that I didn't think of (and you wouldn't have thought of either unless I fully explained it) is that the electronic switch will get all of it's power THROUGH...

    I still have to order the PIC's and MOSFET's. When everything arrives, I'll be back begging for help again on the programming side! Thanks again for all the help!

    Microcontroller controlled by pushbutton for LED flashlight

    I guess I do have a little luck after all... I managed to snag this just minutes after it was listed.

    I have no luck... I just tried to order from Microchip Direct and got the following error message when trying to checkout with PayPal: Paypal transaction failed. We are not able to accept your order with Paypal payment. Please contact customer service for more information. Guess I will call...

    Microcontroller controlled by pushbutton for LED flashlight

    I don't care if it works or not. I won't support counterfeiters. I have had my designs copied by Chinese manufacturers before. It might sound flattering, but it's financially devastating if you rely on it to make a living.

    I'll give that a try.

    Microcontroller controlled by pushbutton for LED flashlight

    I just found that out. I found the basic PICKIT3 programmer at Digikey for $48. I was placing an order with them anyway, so I figured I'll just get it from them. Nope, out of stock...

    Microcontroller controlled by pushbutton for LED flashlight

    Counterfeit is definitely the correct word for that programmer, for several reasons. Mostly the very similar appearance and the use of trademarked names. Normal examination by who? A person that has worn Rolex watches for most of their life could detect a counterfeit with normal examination...

    Microcontroller controlled by pushbutton for LED flashlight

    Looks like this project isn't going anywhere for a while... Getting one soon from China isn't going to happen. It's their New Year this month. Digikey seems to be the only place that can get me one soon. I just can't pay $70 for it though,,,

    Microcontroller controlled by pushbutton for LED flashlight

    Well shit, I wasn't aware that these were being counterfeited. It's too late to cancel through eBay, but I contacted him and asked for a refund before he ships. I'm sure he'll respond with the typical lie "it's too late, it already shipped". If so, I'll open a case with eBay when it arrives...

    Microcontroller controlled by pushbutton for LED flashlight

    My thought was to use a socket like that to program a few micros for prototypes, not mount it on the board. Not worth the price for that purpose though. Thanks for the link to the pins.

    This is nice, but I just can't justify the price: http://www.ebay.com/itm/261118244490

    Microcontroller controlled by pushbutton for LED flashlight

    Thank you very much! I ordered the programmer from here: http://www.ebay.com/itm/331395807656 I paid $3 more, but I'll have it in 3 days instead of 3 weeks as the seller is 150 miles from me. I downloaded the MPLAB software and users guide. For an SOT adapter, are you talking about something...

    Microcontroller controlled by pushbutton for LED flashlight

    I cannot find a better MOSFET than the 2 that you suggested, so I'll get a couple of each of those. Hopefully I'll have room for the larger one that will run cooler. I may be able to center it on the board and mount the switch on top of it. Does the PIC and the TINY use the same programming...

    Microcontroller controlled by pushbutton for LED flashlight

    Correct, if the output in on, pressing the switch for any duration would turn off. Thanks for the suggestions. I'm not very familiar with package sizes, so it takes me a while to narrow down suitable devices. Quick question: If voltage remains the same, does RDSon remain the same if the load is...
