| Date and Time: |
The Lugh contains a time and date clock to provide standard time functions as well
as alarm clock functions. You can even use the Lugh as an alarm clock if you like! Take a nap at the field and let Lugh
wake you up!
|
| Temperature monitor: |
The Lugh can even monitor the temperature and display in either centigrade or fahrenheit.
You can program a temperature alarm limit and the Lugh will warn you when this limit is hit!
|
| The Flight timer: |
A programmable up or down flight timer is provided to allow the pilot to monitor
is flight time and alarm you when its time to land. The Lugh will warn you with “beeps” as your programmed flight time
limit nears.
|
| The Glow Driver: |
The glow driver allows the pilot to control the drive level, the Lugh will measure
the glow plug voltage and current and display the glow plug’s resistance and
power consumption. The Lugh also provides a “enable” button that will start
the glow plug drive function. The Lugh will automatically shut the driver off
after a preprogrammed delay. The Pilot can program this delay time as desired.
|
| The Battery tester: |
The Lugh’s battery test function is more advanced that the normal expanded scale
voltmeter. The Lugh provides a programmable battery load, the pilot can set
the load to his desired value. The Lugh will measure the battery voltage with
and without the load and then calculate and display the battery voltages and
the internal cell resistance. Alarm functions are also provided to warn the
pilot when the battery condition is marginal.
|
| Tachometer: |
The Lugh’s tachometer function allows the pilot to monitor the engine RPM. The
pilot can program the number of prop blades allowing the Lugh to work for most
applications. The prop sensor is on the side of the Lugh, requiring you to
point the Lugh at the prop to make the measurement.
|
| Servo driver/cycler: |
The servo driver function allows you to plug a servo into the Lugh and control
the servo’s position. Lugh will allow you to adjust the position and will display
the pulse width that is being sent to the servo. The servo’s current consumption
and power consumption is also displayed, and you can control the servo drive
voltage! These are very powerful features and this allows you to monitor servo
performance and evaluate aircraft linkage efficiency etc. The Lugh can be programmed
to cycle the servo between program locations and programmed translation rates.
This allows you to test new servos and installations. During this cycle operation
servo current is monitored and displayed. I like to use this function when
setting up a new aircraft, I document the servo pulse widths needed to achieve
the desired throws.
|
| Pulse width monitor: |
The pulse width monitor function allows you to plug the receiver’s output into
the Lugh and measure the pulse with that the receiver is sending to the servo.
This can be useful for system diagnostics and aircraft setup. If you use the
servo driver function to define the pulse widths needed to get the desired
flight control throws, you can then use this function to program your transmitter
to drive the servos as required. The Lugh can make this measurement to within
.5 microseconds, this is one part in 2000 of the standard servo range of motion!
|
| Anemometer: |
By adding an optional sensor you can even use the Lugh to tell you the wind speed!
I’m currently looking at several low cost sensors to support this function.
