F5Bbox for verbal climb counting and set times

So this is what happens when you have too much time on your hands... I had a custom F5B talking timer built to help with my F5B practice and competition. It's a verbal climb counting and leg set timing tool for use during an F5B flight, and then stores this data for immediate review after a flight.

For me, it solves 3 problems:

- Your helper forgets what climb count you are on
- Your helper doesn't exactly know when you should fly your 6 leg sets
- Its too difficult to use the Unilog to know during and right after a flight which sets were the best/worst, how fast the 4 or 6 leg set was exactly, and what the motor on time was (immediate feedback during practice)

How it works:

- F5Bbox connects to a spare receiver on the ground
- The connection is made via a switch that is plugged into the throttle signal
- Throttle signal is used to determine when and for how long the motor is on

Verbal climb counting:

- After each climb, the F5Bbox says the climb count verbally
- After 10 climbs it says Distance over
- A motor cut will not increment the climb count, but it does increment motor on time

Set timing: (optional on or off)

- After stating the climb count, it tells you the number of seconds ahead/behind you are against the cumulative standard 20 second set time.
- Being ahead of the cumulative 20 second set time means you can attempt a 6 leg set in the following climb.
- Sets are defined as the entire time for one “motor on” plus the time between the end of a “motor on” and the beginning of the next “motor on”.
- So it actually says "2 climb, 4 ahead".

Data recorded for every climb:

- Set time and motor on time
- Total remaining time and total motor time
- You can view up to 20 flights of data in the memory
- You can export via serial cable to the computer

I'll post a video in a few days...

Nice...

But if your are going to start production...

1) Serial port will need to be replaced by a USB (but I do like old school)
2) China will need a set of schematics so they can started on a smaller/cheaper model

Kris,

To finish off our e-mail communication as the project went on...... great work!!!

Indeed, i think perhaps a little youtube video would be very effective in showing what it would be like to have the box. Either a dry run in the living room or a real flight with the audio in the background.

Joe

Aiiie, Joe helped in the development, sure it won't blow up when flying too much legs?

On a more serious note, I've been dreaming about something like that , but integrated in my TX. This is actually a better idea. Would it be difficult to make it start my talking timer automatically after 200 seconds as well? I'd certainly want one then....

Wim, i would not say i helped. We just talked about what we would want to have. For instance i thought it would be distracting to have the unit say something during the climb so we put a delay in and also a switch to make it talk less. It is a bit big, i did ask for something that would fit in my pocket but i guess you can't have it all.

Kris did it all him self and then got someone to build the units for him.

Thanks guys. I am not planning to make a production run of these. But I do have a few extras that I had built with my prototype.

Here is an sample data set off the F5Bbox:

Flight#5
#1 SET:17.2 MOTOR:3.2
#2 SET:17.1 MOTOR:2.2
#3 SET:27.4 MOTOR:3.1
#4 SET:16.9 MOTOR:2.5
#5 SET:17.1 MOTOR:2.4
#6 SET:28.7 MOTOR:3.2
#7 SET:17.5 MOTOR:2.4
#8 SET:18.5 MOTOR:2.5
#9 SET:19.1 MOTOR:2.2
#10 SET:19.2 MOTOR:2.5
Total Time: 0:02 Distance Motor: 26.2

The "set" time does not include the motor time?

ah, ok, it's just because I've never timed a "6" set under 30s yet...(never timed Joe either...)
