devices through my car stereo. The input is a male plug that is ...

The # t1.6l is on the fuse that blew in my Dell subwoofer. However, I cannot
find sufficient evidence anywhere to indicate what the voltage and amperage
is of this thing is. All of the charts I have found online are murky at best
and the most compelling information I can find is ...

We are celebrating with a cake and sticky wine......
We thought of sending portions out with each sale but TCP/IP has not yet
been extended to the "Matter Transmission Protocol" so instead we are
offering a 10% discount on all orders placed on the web shop for 2 weeks

Is there much difference in the way these batteries should be charged?  I
have a portable radio that has a charger that tricklecharges NiCads, D
cells.  Could NiMH be used in place of the NiCads without chance of damage
to the cells or to the radio? Any help is appreciated. Thanks.

     I am still looking for parts for a project my son wants to do for
his scout troop on an echo chamber. Due to the fact that we are very
short on funds and bucket brigade chips seem to be a collectors
piece...I figure we could ask for anyone with old record, erase and

In the voltage-current negative feedback,what is the value of the
negative feedback voltage of the output voltage?
It says that "Vref=Vo*Re1/(Re1+Rf)" in the text book,why is that?
Should I consider the output resistance of the emission pole of the

I'm hoping someone could help me with some info for a Proline 7G1r monitor.
Seems to be no go - fuse checks out OK and power seems to be getting into
the power supply OK (main filter cap charges fine), and there seems to be a

I'm after the brightest 20W 12V MR16 bulb for a project. Something around
the 20degree mark. The best I could find was a Phillips part number BUT not
available locally. I've tried all the specialist S.A. lighting places I can
find with no luck. If anyone knows of a specific ...

I am looking for a cheap method of fitting some sort of thermometer to my
hot water tank which is heated from a log fire. The tank is built in to a

I`ve choosed TLC4541 16-bit ADC for my design.
One thing is driving me crazy ..when I connect Vin to Vref (+5V) and do
few measurements one by one i do get quite big noise(error)
here are some samples :

Hi chaps,
I made a previous post about driving a flashing led from
240v ac with a 'or' from two sources, turned out ok...
Here's a different problem I've been toying around with

I have a sound operated camera flash circuit that I built in the 70's.
It has the IC missing.
I thought that it was built from an English Practical Electronics circuit,
but the circuit appears very similar to the ETI 514B published in May 1976.
