October 10th 2020
Although tests have shown that the BeepBox vario has a faster response rate than other varios in its class, there is still a short delay. The reason for this is that the barometric pressure sensor which is used to measure altitude isn't 100% accurate; there are tiny fluctuations in the readings which can be caused by things like electrical noise in the circuit board, small gusts of wind, and even sun light can throw the readings off. To account for this, software developers need to work out some kind of smoothing routine which averages out the raw measurements.
The algorithm developed for the BeepBox, in combination with its state-of-the-art pressure sensor, are what allow it to out-perform other varios. That being said, because of this averaging routine, a small delay in the vario is unavoidable. With the BeepBox Alti-Vario, this delay is typically about half a second. Although this is an incredible achievement in itself, the goal is instant feedback the moment you enter an area of lift.
With this in mind, the last few weeks have been spent trying to see if it would be possible to incorporate an accelerometer. This is the reason that it has been a little quiet in the Development Log recently with only minor updates being posted so apologies for that. Today though, I am excited to announce an important breakthrough for the BeepBox project; a working accelerometer algorithm which gives instant feedback to changes in altitude.
This has the potential to completely remove the sensation of entering a thermal and wondering when your vario is going to start beeping. The consequence of having instant vario feedback is of course, a better understanding of the air mass, improved thermalling, and longer flights.
The next steps will be to incorporate this into the prototype and fuse the data from both sensors together. Watch this space!
Ultimately, this is a major milestone for the BeepBox and the last big change before a final public release.
Version 3.1.32 - October 4th 2020
- Removed a number of routines which were originally intended to preserve battery life. These effectively slowed down the processing rate of the CPU as the battery level got lower. Through testing, it was found that the battery saving achieved from this was negligable so these features have now been removed.
Version 3.1.31 - October 3rd 2020
- Fixed a bug which sometimes occurred when inputting a known altitude.
- Fixed a bug which was forcing the display to refresh more frequently than required when exiting the Settings Menu.

Version 3.1.27 - September 24th 2020
- Disabled the flight recording auto-start function if the barometer window is open.
- Disabled the flight recording auto-start function if the settings are open.

Version 3.1.26 - September 19th 2020
- Added two new settings which allows the main data type on the Home Window and Altitude Window to automatically change when setting QNH and AMR altitude references.

Version 3.1.24 - September 17th 2020
- Small update to Factory Reset menu to improve usability.
- Fixed a bug in the timer which would force it to ignore the auto-start setting under certain conditions.
- Fixed a bug where, on really high-pressure days and altitude readings were below zero, it was impossible to stop the flight recorder.
- Fixed a bug where changing from beginner vario mode to classic vario mode could have a strange impact on the sink beeps.
- Fixed a bug where the flight duration was incorrect if the stopwatch data type wasn't being displayed on the home window.
- Fixed a bug where the system could try to refresh the screen even after the screen had been turned off by the battery saver.
- Fixed a bug where, when a low battery is detected and the system tries to go into standby, it would try to turn on the screen and display a "low battery" message. The resulting power surge could push the CPU beyond its limits and enter an infinite loop which would permanently damage the battery.
- Fixed a bug where the initial calibration and error checking algorithm was interfering with the low battery algorithm.
Version 3.1.23 - September 9th 2020
- Reworked the Sink Alarm.
- Added a test mode for the sink alarm - holding down the Set Button whilst on the sink alarm menu will trigger the sink alarm, allowing the user to familiarise themself with the sink alarm.

- Minor update to flat battery handling.
Version 2.32 - June 6th 2020
- Added a menu option for cumulative altitude gain calibration.
- Implemented a new algorithm to update what's being displayed on the screen. For the most part the screen updates once per second, the vario screen refreshes every 1/4 of a second. Advantage of the new algorithm is more control over the refresh timing, easier implementation of future updates, less drain on the battery, and importantly - pop up messages like "Recording new Flight" no longer interfere with the vario calculation algorithm.

- When running, if battery becomes dangerously low, the device will shut down and the screen switch off.
Version 2.31 - June 1st 2020
- To protect the battery, we've implemented a new battery management routine.
- Previously, the battery voltage was only being measured if on the home-screen or battery screen. This meant that if on the vario screen for example, the battery could be run past safe levels. This has now been fixed: Battery voltage is now measured every 20 seconds, regardless of what screen you're on.
Version 2.30 - May 27th 2020
- Added a mute at start feature - Allows you to keep the vario quiet whilst you're preparing for launch.
- Sink Alarm now respects volume and LED settings.
Version 2.29 - May 25th 2020
