any help is greatly appreciated poeple, i'm just starting out with PIC
programming, and trying to get an LED to flash from a PIC16F628,
i can get the following to comple in MPLAB IDE without errors
(most code is "borrowed" and modified from other sources

All,
The lead acid battery in my home alarm system is depleted and need
replacement.  I have a question and hopefully someone expert enough can
answer this.  Is there a good reason that I should not replace the battery

hey I was wondering what would happen if you tried to recharge a
nonrechargeable LiPoly (Li-(CF)n) battery. I think you would make Lithium metal
and fluroine gas, thus making a lithium-fluorine battery, about 6 volts.
Anybody dare to give it a try?

I'm building a cabinet switcher for my guitar rig.  It will be relay based,
and I need to provide a dummy load for amps that are not in use.  The
biggest amp is 120W, but I figure that a 50W resistance ought to be enough
just for safety's sake.  There are 4 amps to consider, plus ...

I was wondering if anyone knew of any links to a site which could
provide some info/pic code on  building a capacitance meter using two
555 timers and a 16f874 .I'm hoping to take the time difference
between the two timers when an unknown capacitance is introduced to

Could anyone tell me some info to develop a basic robot.....& is
it possible to control  a stepper motor through parallel port

Looking at datasheets for crystals, they specify its tolerance as +/-
100 PPM. What does PPM stand for and how do you calculate the
tolerance of the crystal in terms of frequency?
Thanks,

Love is like a PCB board, the circuit is running in all directions but they
are coming out from the heart of the board and we have soldered the major
components such as glittering eyes, smiles, lovely smiling faces.
When four eyes meet, the love of fire started and electric current ...

I have an RCA 36 Console TV model G35302WK that is +/- 13 years old.  The
picture lately has started to 'grow' in the sense that it has expanded
beyond the tube limits and therefore a slice of the picture on the extreme
left and right has disappeared.  If this were my computer ...

hey i notice that D size nonrechargeable batteries never explode while charging
and can be charged quite a number of times. give it a try

Electronic electricity repository is an energy concept that aims to accumulate
and store electrical energy from any source.  The storage would be intended to
accommodate such things as electric vehicles, home heating, etc.  The best
example is the EV - an electric car that would run ...

Anybody knows a working binary clock schematics, to assemble it by my
self ?
something like the one at thinkgeek but i want to have one done by me
to put it on a chasis.

Ok, here's the problem. I added flush LP mount lights to the front of my
motorcycle(ditching the huge stalks/signals) and they look great. Problem is
they're 23 watt instead of 28 watts (1157 bulb) and the signals flash
quickly. Is there any way to slow them down???? There is no ...

From what I am read now on an internet site, I understand that radio waves
moving through the atmosphere behave quite differently at different
frequency. This is due to the effect of the sun on the atmosphere, and it
changes from day to night, as well as from year to year. Is this ...
