delta5_race_timer's Issues

not working on rpi 4b and newest piOS

hello,
I am struggling on my raspberry pi 4B 8gb version with newest PiOS with desktop... unable to run server
there are multiple errors like flask is missing etc

Any idea how to solve it?

Database Clears on System Power Cycle

Database resets on a power cycle when it shouldn't.

Race Page Leaderboard Formatting on Mobile

The leaderboard does not scale well on mobile device screen sizes.

Map and constrain the RSSI value

The RSSI value can be over 255 which isn't handled well by i2c unless the number is conditioned. Possibly use the map() and constrain() functions to keep the values within range.

list index out of range

The delta5 timer was working yesterday, but today when I try and start it, the service exits with error list index out of range

Not sure how to recover from this. How does self.nodes[node_index] go out of range?

hacker's question

I am delighted to find this excellent project.

In delta5node.ino it looks like there is a hard-coded i2cSlaveAddress. This is used for wire initialization, it is also printed for our convenience.

But there is also a mechanism for the master controller to interrogate the slave nodes for that address… but to do this, the address would already be known.

Car 54, what is your car number?

Or I am missing something probably. Is there a kind of master broadcast that is used to find all slaves?

Race Leaderboard Not Properly Sorting Fastest Laps with Tied Laps Completed

Support more than 6 Nodes

right now the trqacker is limited to 6 nodes. Is it possible to change the code to support 8 nodes?

would be awesome!

Discard or highlight falsey laps

Add a method to mark or directly discard falsey laps.
Add a minimum lap time value to the race config.

Eg. A lap for some track cannot be less than 5 seconds so we mark it in order to delete it easily.
We could also add a bulk delete button with those times

Clear Database separate by pilots list ,heats or Rounds. Store last database

the ability to separate how the database is clear was a good feature . specially if you have a 30+ pilots events

if something need to be reset you dont have to start from 0 .

also in the latest version database is not been stored. when you turn off the system database resets.

Issue Getting Delta5 to work

I've been trying to get the app to run by following the Software Setup Guide, but when in the settings this error keeps occurring.
This only happens in the settings, and I'm unable to add pilots or heats.
None of python files were changed after cloning

Any help would be appreciated.
Thanks.

Round Summary Page Dies When Some Race Results Have Zero Values

Event Summary (Standings)

would be nice to have an summary just like the one you are planning to do for the rounds page but for the entire event. with the ability to sort by columns

position by (rounds,laps,avg lap time or fastest lap)

Example
position -pilot name - Rounds completed - Laps - Average lap time - Fastest lap time

RSSI not working correctly

I have everything built and programmed as instructed. When I'm the GUI for LiveTime it shows all the nodes at 570(+-5) and no changes or spikes when I power up a transmitter. What'd I do wrong?

Minimum lap time

Add minimum lap time so it discards short lap reads.

Improve phonetic readout of lap + time

Right now the phonetic readout of the pilot plus lap plus time is a bit hard to comprehend because the lap number bleeds into the time.

Example: "Paul lap one one minute five seconds"

I believe this is the line responsible:

delta5_race_timer/src/delta5server/templates/race.html

Line 94 in 47a3573

var $ttstest = msg.pilot + " lap " + msg.lap + " " + msg.phonetic;

I am going to try modifying this function on our timer to something like this (to be tested still):

		socket.on('phonetic_data', function (msg) {
			//	var $ttstest = msg.pilot + " lap " + msg.lap + " " + msg.phonetic;

			var phoneticLap="";
			switch(msg.lap){
				case 1: phoneticLap = "st"; break;
				case 2: phoneticLap = "nd"; break;
				case 3: phoneticLap = "rd"; break;
				default: phoneticLap = "th"; break;
			}
			var $ttstest = msg.pilot + " " + msg.lap + phoneticLap + " lap " + msg.lap + " " + msg.phonetic;
	
			speak('<div class="speech">' + $ttstest + '</div> div.speech');				
		})

That should hopefully cause it to say: "Paul first lap one minute five seconds"

Add Filtering to the Rounds Page

The rounds page will become hard to navigate after a lot of races of been saved. Put a dropdown menu at the top to filter by heat.

installation not possible with Pyhton 2

With current RaspberryPi OS (recent install von 01.01.2021, Python 2.7.16) installation stops at bidict (No matching distribution found for bidict>=0.21.0) for python-socketio.

Update RSSI trigger function

Currently if the average RSSI is above the threshold limit (or lap trigger) this counts as a good lap read. Look into using a rising edge detection or a peak detection to determine the trigger. The trigger calibration could still set the minimum threshold required.

For reference:
https://www.tigoe.com/pcomp/code/arduinowiring/46/

no such column polot.phonetic

I just upgraded my lap timer after sitting on a shelf for months. Now getting this error

OperationalError: (sqlite3.OperationalError) no such column: pilot.phonetic [SQL: u'SELECT pilot.id AS pilot_id_1, pilot.pilot_id AS pilot_pilot_id, pilot.callsign AS pilot_callsign, pilot.phonetic AS pilot_phonetic, pilot.name AS pilot_name \nFROM pilot \nWHERE pilot.pilot_id = ?\n LIMIT ? OFFSET ?'] [parameters: (1, 1, 0)] (Background on this error at: http://sqlalche.me/e/e3q8)

It seems like the database schema has changed, but I can't find any documentation or scripts to update it.

Create delta 5 github organization

I'm excited about the possibilities of delta 5, I want to help contribute. Have you considered making a github group called 'delta 5'?

Reasons why it may be a good idea:

1. Looks more profesional (can have own logo)
2. Can use github pages to host simple website
3. If you have more than 1 git repo (which the automated raspberry pi images would be), it is cleaner to have them grouped together
4. Github forwards links to scottgchin/delta5_race_timer so existing links won't break.

Here is an example of another project I've contributed to that uses a 'group' for all related repos:

Restore previous 'delta5node.ino'

Commit d17dcdf ("timing server LED") reverts the changes to 'delta5node.ino' that came in via the previous commit d0df601 ("Modified node to use freqMhzToRegVal() fn instead of table") for no apparent reason. I think the previous 'delta5node.ino' should be restored.

Different tuning param for 25mw 200mw /600 mw race

HI,
It will be nice to have tuning preset for different power race type.
What i mean is to have tuning preset for race with 25mw , 200mw , 600mw VTX
race.

Differences in the data the mock interface outputs vs the live one.

I've been trying to get livetime to support signal strength from delta5 but since when
--mock is used that data is not there they would like the mock interface to be changed
to match the live one.

I figured i'd check in and see if there was any interest in merging such a change
or if this repo is more or less completely idle at this point.

I'm willing to write the code myself and submit a pull request if there's interest.

Automatic Heat Creation

Add a function to automatically assign pilots to heats.

Look at adding a class/skill field for each pilot that would be used when assigning heats.

reset database doesn't work

Running the latest code as of a couple of days ago. When I click 'reset database' it asks me to login and then refreshes the page, but the database didn't reset because I still see pilots and heats.

Intergrate Delta5 in DOCKKING from furiousfpv

Guys,

Furiousfpv released the Dock-king
http://furiousfpv.com/product_info.php?cPath=29&products_id=451

Now i was curious if someone here is prepared to talk with Furious to make a Delta5 that is talking with the Dockking, so we make one for personal, 1 node. SO we can see laptimer in the OSD.

How cool is that, and if that is working, make then a small event box, for 8 dockings so, the racers is seeing his place and time in the goggle

How does it integrate with live time?

I'm just learning what live time is. The documentation says

Alternatively, to use your Delta5 Race Timer hardware with 3rd party timing software, replace each reference of 'delta5server' with 'timingserver' in the following instructions.

Does live time run on the raspberry pi?

There have been some facebook discussions around switching between the delta 5 server and live time. I'm trying to figure out if there is a way to run both services simultaneously and use a proxy to route network traffic based on the source url.

Could you elaborate on why there is a need for 2 different services to be running?

Timed back up (every 15 to 60 min) of the database also a way to restore to the back up.

I would like to see a timed back up (every 15 to 60 min select option in GUI) of the database.
It would also be good to have a way to select and restore to the back up from the GUI.

Lipo Voltage Monitoring

Would be nice to have that option to check the Li-Po voltage and an alert when the voltage is low.
I know that it needs a PCB modification but could be easy to make.
Chorus Laptimer has the option and is using an analog input of the arduino for it.

receiver swamped

I am experimenting with the Delta5 concept and I observe that the RSSI from my receiver achieves a maximum output with the transmitter some distnace away - there is nothing like a peak to detect, it is a plateau.

So I came looking for a way to desensitize the receiver. Since I know nothing about RF, my experiments were only amusing failures. Never mind.

Or find sympathy, or assurances that it is just the truth. The implication would seem to be that Delta5 is only satifactory on larger tracks?

TIA

Add shutdown button to safely shutdown the raspberry pi

Safari on iOS speech support

For some reason the speech doesn't work in Safari on iOS devices. I believe this can be fixed since https://responsivevoice.org works in Safari.

Add an export saved races option

Ahead of multi event database management the next step would be a button to simply export the current saved races to a csv file.

Move Race Timing Clock to the Python Script

The race timing clock is currently javascript on the race page. It does not persist if the race director navigates away from the race page and then returns. Move the timing clock to a python function with socket io updates back to the race page as needed. This might involve needed a separate emit for each audio cue as well.

Delta5 integration in MultiGP LapSync Race Timing Desktop Software

It would be nice to have Delta5 in MultiGP LapSync Race Timing Desktop Software.

Add frequency Schemes and Make Changeable

HI
So this is my first open source project I am starting to help work on so please be kind. My idea is on the database page add a drop down for the different frequency schemes (IMD5, IMD6C, etc). I also want to make this changeable from the settings page, so it won't require clearing the DB to change the scheme.

I have already started working on this, just wanted to let people know.

I will probably need some help or advice once done merging it back.

Add Heat and Pilot Notes for the Race Director

Add additional text fields next to each pilot and heat for note keeping. For example a heat note could state that it is the 'beginner class'.

Add a Beep Tone on Each Registered Lap

Add Round Summaries on the Rounds Page

Under each heat on the rounds page should show a summary similar to the leaderboard from the race page.

Add a public facing page showing the current race laps and leaderboard

Calibrated each node

Maby a idear,that we can calibrate each node, so the quality diffrence is not a issue anymore

Delete the database so you can start again if there is a problem the delta5server GUI.

I would like to see in the delta5server GUI a way to delete the database and restart the PI so you can start again if there is a problem.

On next release set the default port to 80

The release will also need to note that any previous Apache installations be removed.

Add repeated i2c attempts when first detecting nodes

Automated Rasberry Pi images

It would be nice to have a pre-built raspberry pi image.

pi-gen is the tool used to generate the pre built images on raspberrypi.org
