I really like that!

Google just does not return anything from Jameco, the only supplier that has them. Here are the 7805's at Mouser: http://www.mouser.com/Semiconductors/Power-Management-ICs/Linear-Regulators-Standard/_/N-5cg9g?P=1z0z73r&Keyword=7805&FS=True And from DigiKey (this link shows more package opti...

"The other side of the world" link that SETEC put up is really cool. And, hackles, you were right. I would wind up drowning in the Indian Ocean

I knew you could do it manually but I am lazy Besides, a cool UI linked directly to a map would be cool. Too bad I don't do web programming (and don't really want to). I will check out those links.

Last night I was talking to my son and we got on the subject of digging a hole all the way to the other side to see where we would end up - don't ask how we got on the subject - I don't remember. Obviously digging a hole all the way through the earth would require more time and shovels than we have ...

Got 'em! http://search.digikey.com/scripts/DkSea ... -3138-6-ND

I looked before but I didn't realize what the "Alternate Packaging" meant. Instead of buying 4000 at a time, you can get them in lower quantities!

Thanks for the help!
Kevin

I will check that one out. the data sheet says "Capacitor must be low series resistance (< 3 ohms)"

Thanks!

I need to find a SMT cap - somewhere that has them in stock and where you don't have to buy 4000 at a crack. It MUST be a low esr cap. Preferably in an 0805 package but I may be able to use other packages. Ceramic type. X5R temp. coeff... Between 4.7 and 10uF and at LEAST 6.3wv. I designed a circuit...

No problem - I am married so I am used to being ignored

ISR = Interrupt Service Routine. You setup the timer to trigger an Interrupt. Every time the timer reaches 0, the processor will fire an interrupt (provided that interrupts are enabled). When the interrupt is fired, the processor will switch control to an ISR (which you have to write). Note that the...

If the button(s) is(are) debounced, you would want to get the first button press. Note the "time" when it was pressed (i.e. have a 1ms timer running in an ISR and producing a "ticks" variable to count the milliseconds). Then, if the button is released and pressed again in a given...

Why not just a really simple circuit that uses a phototransistor over the boardmounted LED (factory) that will in turn switch on a really loud buzzer and additional (brighter) "alert" lights in time with the blinking LED. Self contained and doesn't detract at all from the original (semi)f...

// begin ramblings Thanks! And, btw, I finally got a Pickit3 (my wife "got it for me for xmas"). It seems OK so far. Why did I get it, you ask? Because the debugging support on the Pickit2 for PIC32's is pretty much non-existant and I am working on a PIC32 project. From what I have read, t...

If all else fails (as far as tinkering with the internals of the equipment), maybe you could put your circuit on top of the blinking LED - double sided tape/velcro. Use a sensor to catch the blinks and then sound a buzzer, light a light, etc with the signal that your light detector creates.

No - I only tried it with a D cell battery at first. But, what I did was run some very small wires from the output of the rectifier and I re-assembled it - with the two wires dangling outside. Hooked up my meter and gave it a twist. Good voltage all over. So, everything in the flashlight works - exc...
