lots of DC motors, steppers, gears, encoder wheels, IR emitter-detector pair
sensors, etc. from old inkjet printers.
I'd really like to get some servos to work with, and I've been Googling

I have a Honda Accord Euro 2005 while driving the headlights, speedo and CD
player cut out for a second this occurs
regularly.  Advised to change battery but this has not done anything.  The
engine does not stall.

I'm doing my project in university. My project is to replace a DC
drive by a AC drive using inverter.
The old DC drive parameters are:
- Power 450kW

I have just acquired a daughterboard based system for the ECU in my car. It
uses EPROMs with updated/revised/modified data to allow different components
to be used on the motor.
The chips currently installed are AMD AM29F010B chips. I'm looking for a

Hi, I am planning to restore the above as I can get hold of the components.
The radio receives lw/mw and 6 sw bands.
It was working ok and then the volume suddenly dropped to about half that it

copy of the original circuit and circuit notes?  Would appreciate a
copy.

YOU KNOW THAT YOU SPEND AT LEAST $6.00 "EVERY PAY
PERIOD" ON USELESS STUFF, ME TOO. SO I THOUGHT, WHAT THE HECK, I'M
GOING TO TRY ONE OF THESE "SCAMS". NOW TO MY AMAZEMENT, I AM CHUCKLING
ALL THE WAY TO THE BANK WEEK AFTER WEEK WITH My PILES OF 1$ BILLS. I

This falls under the ehading of "dumb questions" for some, I'm sure.
In Schematic, semiconductor elements appear with their pins labelled with their
function (A/K, E/B/C etc) whereas POST expects 1,2 (,3) etc to be able to
generate a valid netlist  - otherwise none of the ...

As from today I have to hold the power switch in all the time otherwise it
switches itself off. I used to be able to just press once for on, and again for

I know very little about electronics (E=IR is about my limit).
A relay on the control board for my espresso machine switches power to
the 1200W heating element.  Normally, it closes each time power is
called by the thermostat device.  But lately, the relay clicks but
