First of all, Happy New Year!
As I use a VCTCXO that has around 1V as a Output Voltage Level and this
output clock signal should be a input to 3.3V clock buffer, so I have
to make this clock signal level to be about 3V for clock buffer to

Here is some video on YouTube of my permanent quadrupole magnet.  It is
actually a magnet with 4 poles, and they are only found inside of
particle accelerators used in nuclear labrotories.

Sorry to interupt the debates with an electronic design related
question, but I was wondering what is the best thing to do with unused
offset bias pins on an OP07.
Is it best to just leave them oc or can anything be gained by eg tying

I'm attempting to temperature compensate a lead acid battery charger and
would like to use the thermal properties of a diode to do that. I know
that for a silicon or germanium diode (at a fixed current) that the
voltage across the diode varys about -2.5mv/degC. In the circuit I'm ...

i want to make connect two microcontrollers in one circuit.
But the circuit will function only for one application.
So how can i connect two microcontrollers in the same circuit.
My plan is to connect one microcontroller as a master and another one

Hi, I would like to protect a torroidal transformer for an audio project
from over temperature. Would a 70-80oC resetting thermal trip be acceptable
to pot with the transformer.
Thanks

My recent experiences purchasing an audio amp afford some points for
reflection on the electronics of such.
I purchased a NAD C325BEE amplifier, basically the cheapest 2-channel
integrated amp on the market ($399).  One might surmise then that I

I recall a palette load (5ft high) of LED Christmas lights
disappearing in days at a department store. There everywhere!
Fk I made an LED Christmas tree using SMD LED's in 1998. It was
controlled by an MCU. I had that thing lit up like a computer

I am presently using CoolEdit to generate modulated audio tones for
test purposes. The only FM envelope that is possible to define is a
sine, square or triangle.
Is anyone aware of a software signal generating application (Windows

Hello members of sci.electronics.design
Question: Is there a cheap hand tool for winding toroids?
Purpose: To make various toroids for experiments. Low budget.
Problem: Winding various wire lengths on various core sizes (ex

New book describes how to design a good switch mode power supply. The
book also goes on to describe how to make chocolate milk from dog

Nuff said!

Just got an Extech LCR meter, and it displays the Q of an inductor at the
same time as the inductance.  Only it says that the coil I wound has a Q of
.132, when the Amidon tech manual inidicates it should be somewhere around
110 or higher.  That is at several MHz, however, not ...
