Have you built the popular RCT Jeti FuelSensor? Here’s a all-in-one app to you! A reader sent me email and wanted a “ECU-type” display to his DIY FuelSensor, so here is my view of it.
FuelDisplay for RCT Jeti FuelSensor
App is simple by principle, read the values generated by RCT Jeti FuelSensor and show them in one double-telemetry-window:
Well, very simple!
- One double-sized telemetry-screen with all info
- Shows consumption
- Shows fuel flow
- Shows tank-percentage remaining as bar graphics
- Compatible with RCT Jeti FuelSensor
Available for DC/DS-14/16/24, requires firmware 4.22 or higher. App does not run with older firmware.
In short: Copy the .lc (or .lua, the .lc is memory-optimized) file from github here to your transmitters Apps-folder, if there is a translation file copy the .jsn file to Apps/Lang-folder on your transmitter. Head on to “Applications” -> “User applications” and add the app. Guide on installation of Lua-apps available here if you need some more in-depth guide.
Setting up and usage of FuelDisplay
After installation open the app and you are presented with easy setup with only a few options:
Settings are self-explanatory. While the fuel alarm at xx percentage is easily done with tranmitters alarms I wanted to put it here so you can have a voice-label to it. So, select a voice file, for example “Low fuel”, set the alarm at for example 25%. When you are using fuel and you get to the point where there is 25% left transmitter sounds the alarm as “Low fuel, 25 percent”. Alarm is generated once. For the alarm to be possible to trigger again fuel remaining needs to be above alarm-limit, basically that means you need to refuel.
Sensor-selection is different than usual. Instead of selecting a specific sensor value we are selecting only the sensor itself:
You need to select one of the sensors, in the picture above there is a few DIY-sensors available so I need to select the “RCT Fuel”. So when I’m done with setting up the app it could look like this:
With these settings when I have 25% fuel left transmitter will announce “Warning, 25 percent”.
Add FuelDisplay to your main screen
Go to “Main Menu” -> “Timers/Sensors” -> “Displayed Telemetry” and add “RCT-FuelDisplay” to your main screen. Easy.
- 1.0 Release version
- 1.1 Added German translation courtesy of Alexander Fromm – Vielen danke!
- 1.2 Alarm-announcement possible only if sensor is active
Some rules do of course apply!
- Never use Lua to control a function that would take the model down if misbehaving!
- Always, always test the function thoroughly before flying!
- If you do not know, then don’t!
- RC-Thoughts or myself is NOT responsible for anything this application does
- Applications are free to use (MIT-license) and linking to this page is encouraged!
