I am trying to implement a 24 bit random bit shift register in a small
microcontroller. The output will be used as white noise and fed into an
IIR pink noise filter also implemented on the MCU (see other posts, yes
its possible). I need an 8 bit random number, so I am shifting the

I have a D cell boostcap... 350 farads, 2.7V. Takes several minutes to
charge up on a 3A 2.5V bench supply. The volts tics up a 1/10v every
second or so. I want to make a dc-dc conv that will chop the cap
voltage and step it up to about 14v. I'd like it to work from 2.5v down

I have two 2.1ghz VCOs (smv2100l) wich need to be 455khz apart over a 200mhz
range.
I made a pcb to test how they worked with manual tuning and a diode type
mixer to observe the beat frequency,

I just purchased a baseline flash microcontroller programmer for
programming 10f series pics. Unfortunately I'm having a difficult time
getting it to work.
The software recognizes the programmer fine and everything seems to

I am wanting to take a signal and put it into a 4 to 10 decoder.  The
outputs of the decoder are going to be connected to a 10conductor cable
which will connect to the inputs of a 10 to 4 encoder.
I am then wanting to check the output of that encoder with the inputs

I have just installed a Generac 5244 generator.  I bought it from a
dealer that does not service in my area (I know, I know....).
I hooked it up (and made absolutely sure everything was done according
to the specs...)

Hi, Im looking at generating RF and LO signals 450khz apart at various
frequencies from 100mhz -> ~2ghz, wich proved too tricky doing it with vcos
at the top end, even at 100mhz it seems I need oudles of
seperation/screening/isolation and decoupling etc so Im thinking of using a

I am designing a tube amplifier, and I need to make/buy a transofmer that
provide about 350-400v. Where would I find such transformer, or the magnetic
core at least?
Thank you for your time.

New Program : LINELEN.exe
This program calculates dipole feedpoint impedance, transmission line
input impedance, and balun input impedance, versus frequency.
Dipole and line can be of any length.  Line Zo can be of any

We just tested the gate blowout voltage of a couple of 500-volt,
300-watt power fets:
IXYS  IXTH11P50    p-channel     80 volts
IR    IRFPS37N50A  n-channel    115 volts

Is it possible to buy this cpu ..?

hi i m a student of electrical engineering 2nd year.i want to design a
mini project in verilog HDL .CAN ANY ONE HELP ME.

I'm having trouble getting a transistor to work the way I thought it
should, and I hope someone could help me.
I'm using a PIC to drive common anode 14-segment LEDs. Since the PIC
I/O line can't supply enough current, I'm trying to use a 2N2222
