Driving a Capacitive Load - You've been warned! Do not attempt to drive large
capacitances with your op amp, severe overshoot and ringing may occur. But what if
you're stuck driving a length of coax cable that's unterminated? You could end up with
over 1000 pF that sends the output ringing. What causes this behavior?

Dual Relay Driver Board - We have used two Goodsky RWH-SH-112D 12V relays, coil
resistance 400 ohm. It is rated to switch 250VAC at 12A. However, because of the PCB
track thickness and width we do not recommend using the
relay to switch more than 5A. If you….(electronic schematic added 08/08) |

Fast precision LED driver - The circuit allows a precision regulated drive current
to be set to drive an LED, and in response to a TTL level signal, the LED is switched
on and off with rise and fall times of less than 500 nanoseconds and less than 7%
overshoot. This was designed for biological experiments to study the photo repsonse of

Feedback Circuit Eliminates CCD Driver Delay Mismatch - 09/18/03 EDN-Design Ideas:
In a CCD (charge-coupled device), packets of charges shift across the array. The
transistor array, also called a bucket-brigade shift register, receives drive from a
dual-phase clock signal. Dual-phase clock signals comprise two synchronized clock
signals that are 180° out of phase. High peak-output-current CCD drivers.....(design

Flyback Transformer Driver - This is by far the best project for someone who is
already familiar with High Voltage, but wants to take their experiments to the next
level: It requires very little previous experience and skills with soldering and
identifying components, and there are virtually no adjustments to be made. The danger
is minimal, as fly back transformers are intrinsically low power devices, not capable
of outputting lethal currents (due to the hair-thin secondary windings),
and....(circuit added 09/08) |
