    if there possible for pic to faulty?

    OK, those resistances would limit the current that flows into the PIC, so it probably has not been damaged. It's possible that it's damaged, but try it with a regulator first; it may be fine.

    if there possible for pic to faulty?

    A voltage divider is inefficient, but it also will not provide a stable output voltage. This is because the current drawn by the PIC (which includes the current drawn by the LED, which flows through the PIC) affects the currents in the voltage divider, and this affects the output voltage. In...

    if there possible for pic to faulty?

    By "VDR circuit", do you mean a voltage divider made with two resistors? No, you shouldn't use a voltage divider to provide power to the PIC. Use a small 5V regulator such as a 78L05 (see http://www.digikey.com/product-detail/en/MC78L05ACP/MC78L05ACPFS-ND/1049368). These need a decoupling...

    pic18f2550 serial communication

    Post a schematic of your serial port hardware. You could try adding a pullup resistor on the transmitted data pin on the PIC, if the RS-232 driver (or whatever you're using) doesn't have one internally. Can you capture the signal on the transmitted data pin from the board to the computer at...

    if there possible for pic to faulty?

    "SW1" is #defined to a bit in an I/O port register, so every time it's tested in the while (1) loop, the actual pin state is being checked. (Those I/O register bits would also be declared as volatile in the header file.)

    Votage Selector plug on back of transformer

    If a standard US mains plug fits into it, perhaps you could use a standard US mains plug, with its pins connected together internally, as the link? You might want to modify the plug shell somehow (e.g. grind it down, dip it in bright coloured paint, etc) or even replace the plug shell with some...

    Computer SMPS MOSFET replacement

    Most likely the main switching transistor(s) or MOSFET(s) will also be damaged. These are on a big heatsink (usually the largest one). The damage may be visible, as with the small MOSFET you've already identified, or it may only show up if you measure resistance between the centre pin and the...

    rain warning device

    Well, of course, you could put the rain detector panel on the roof, but that would just make it inaccessible, and yield no advantages. If you mean that you could put a detector strip along the bottom edge of the roof (perhaps in the guttering) to collect rain that falls on the roof and slides...

    Well I'd better make sure I got it right! Actually it's "untalented", not "talentless". http://www.quotationspage.com/quote/70.html Right, Journey and Foreigner are kind of interchangeable, I think. Also, from the same period and in the same style, Toto.

    LOL Chris :-) I'm not a fan of rap either. A lot of it is pointless boasting, and I fail to see why anyone would pay money to hear some dickhead talking about how fantastic he is and how many hos he's ****ed. Some, I think, has merit, but would be better written down. I once bought a CD single...

    LOL! Well, I guess everyone's entitled to their opinion, and what works for me doesn't necessarily work for you, and vice versa. I've just been listening to "She's Got It Bad" by Simply Red, and that's a perfect example of what works for me. But like any preference, preference in music is a...

    I'm listening to Stockhausen's "Helikopter-Streichquartett". It sounds like a string quartet playing randomly, accompanied by a helicopter, and a vocalist saying weird sh!t. Seriously. I quote from the Wikipedia article: "The rehearsals were already marked by objections from the orchestral...

    I know what you mean, but I would never say that about Huey Lewis and the News. I think some of their earlier stuff was so-so, but I just love each band member and the sound they make. Partly it's because their greatest albums coincide with my early to mid teenage years, when we all cement our...

    Ones from Dave's list that I'm a fan of too... Pink Floyd - amazing, amazing guitarist! Queen - great songs and arrangements Rolling Stones - classic songs Eagles - ditto Elton John Fleetwood Mac - yes, another band with a great groove! CCR - yeah, classic rock. I've played many CCR songs in...

    rain warning device

    Yes, of course. I wonder how long it would take to tin a 200x200 sheet of stripboard!

    Trying to make analogue sound to lcd?

    Very true Dave. Most of us are certain enough of our position that arguments only serve to compromise friendship and respect. Actually, I wasn't specifically referring to religion as an irrational and unsupported belief; I was discussing the supernatural and paranormal. This thread started off...

    Toshiba CRT TV Model 21S1ES- No picture

    Based on your description, and the fourth picture in your original post, I would say that almost all of the set is working fine - the internally generated menus ARE displayed on the screen. This implies a problem in the video signal path. I would suggest looking at the video input selector IC...

    Trying to make analogue sound to lcd?

    EXCELLENT explanation Steve. I think it's very unfortunate that these ideas of supernatural realms and paranormal phenomena are so appealing to so many of us. It just doesn't seem to be part of human nature to be skeptical and rational; it's more comforting to believe that Great Aunt Jemima is...

    Actually it fell out during his descent of the First High Mountain, and burnt his toe. But the principle is sound.

    rain warning device

    Yes, I also thought of the stripboard with alternating strips connected together. But I think copper would corrode quite quickly. This is the problem with anything electronic that gets left outside. You would normally cover a PCB with conformal coating to protect it from the elements, but of...
