Late, off-target, and wimpy:

"... tidal waves are highly unlikely."

I purchased a Belkin Tunecast II FM modulator and have been less than
thrilled with its performance in a vehicle.  I have an XM SkyFi2 with a
built-in modulator that provides an excellent signal, so surely there must
be something better out there than the Belkin.

I am becoming some sort of barcode scanner junkie. Although I have no
compelling use for them I enjoy exploring and playing.
Recent I got an LRT3800 Spectrum One unit with a 3865 cradle. I have
found only a Product Reference Guide which covers only the basics.

I have just built my first dsPIC-based circuit, with a 30F3011 and
20MHz oscillator. However, I cannot get the thing to talk to my ICD2.
It seems the oscillator is not running; CLKOUT is at a constant 5V and
CLKIN is close to ground (I am using an oscillator with built-in caps).

I have 3 mosfets:
a) 1 for line powered flyback convertor switching, Peak Drain Voltage
is 500V
b) 1 for high side of 12V DC motor control (for free wheeling)

Picked up a pair of those two for 5 bucks shake lights Walgreen's is
pushing this Xmas.
Complete box copy from mine (typos and "Engrish" *ALL* the box's fault!
- I ain't makin' this stuff up, folks - I don't need to - it's printed

Depending on the price I may want to build my own coax video
cable to connect a "standard" tv to dvd player (and other things).
The video jack is an RCA.  It's marked with a yellow band
(impedance spec?)  What coax cable type is best for

hey im a sophomore in high school and I need help with a project o
affecting the strength of a magnetic field...... first of all m
project is seeing how certain materials can affect the strength of
magnetic field, created by a bar magnet and a neodymium magnet. Th

On page 57 of January silicon chip magazine, an ad by Jaycar for a smart
card programmer seems to imply that hacking of smart cards for extra
channels is possible?
Does any one know if this is the case, or is it just Jaycar trying to flog

i know the lithium batterys pop if overcharged but all the plans i've seen
have curr/temp/volt/time feedback loops and emergancy trips on them. what
is the minimal setup if i trickle charge and don't care how long it takes?
are they realy that sensitive?

After ripping 2 or 3 CDs the Drives become bush and won't
reset when a new disk is inserted. This in turn causes media
player to partially hang in that it can be closed but is still listed
as an active process in the task manager......

My camera/flash project circuit is coming together. Now, the next issue,
since I dont want to have 20 foot long wires running between the camera,
project circuit, and flash units, are there easy to use, RF
transmetter/reciever on a chip, type devices. The range only needs to be

When using LEDs in TTL circuits, should I use a transistor (or something
similar) to drive LEDs so that the LED does not affect the rest of the
circuit too much?

There are some companies manufacturing large LED based TV-like, color
display units.
