Since beginning the SkyAssitant was sold in a medium size box with manual, USB cable, flash drive. Box inside has a foam and full color sticker on top. This kind of package is OK, but has some disadvantages. Most important is high demand for manual work. Now I have some other project to process and have to limit labor-intensive tasks. Other disadvantage is size and cost of shipment. Variometer is light, but the USB cable makes package fit in the weight range "up to 350 g".
My proposition is to sold SkyAssistant variometer in smaller box, without USB cable (everybody have it), without flash drive (software can be downloaded from SkyAssistant website), without foam inside (simpler production) and full colour laser printed sticker (smaller cost).
To re-compensate smaller content can sell the variometer in price reduced by 10 Euro, so the end user price with the Eco packaging is 219 Euro. It can be ordered in PitLab.Shop.
Of course previous packaging set is still available.
On the picture below is comparison between both versions.
I call this package "Eco" because is economic and more ecologic. Since we are in EU structures, we have to pay fee for packaging placed on the market. Smaller package means smaller amount of rubbish to recycle and smaller amount of fuel consumed in transport.
For your comfort we extend PitLab.Shop shipping offer with worldwide speditor, the DHL.

The test team together with users every day suggests new functionality for our FPV System including OSD and Autopilot. Now we have pleasure to announce version 2.09 with many new features and correction of diagnosed issues. Full description can be found in the Download page of the FPV System project.
In last days was finished PCB for beta test version of ground station and send to manufacturing. This version will be manufactured in very limited volume only 15 pcs for tests purposes. After test period will be created commercial version of the board.
Board looks like on the pictures below (click to enlarge).
Ground station will have big LCD on the front, tracking antenna driver, 2 channel video diversity, SD card for telemetry logging and measuring of current consumption on the ground. Will be mounted inside plastic enclosure

New version 2.08 of software and firmware for our FPV System was created and tested. Biggest changes concern the OSD. Since now on the screen we can see statistics of actual and average energy consumption per kilometer (like fuel consumption per 100 km in the cars). OSD can show ambient temperature using external LM355 sensor connected to User AI1 black connector, or show temeprature measured by internal sensor at Autopilot board and display air speed measured by Eagle Tree airspeed microsensor connected to I2C orange connector.
Another very important feature is better way of displaying remaining battery capacity. Now we use energy consumed during flight compared to total battery capacity. The battery capacity can be set by user before flight. Up to 12 different batteries can be defined. Using this information the OSD displays information about battery discharge using 28 stages. Also some of graphic details have been improved.
Video below (taken from the test flight) shows what it looks like:
I made another external module with GPS and magnetometer. This time I put on board 3 different magnetometer sensors to be independent of the availability of equipment and to be able use this module in another 3-rd party projects where due to magnetic interference is required to mount external magnetometer. Of course on the board will be mounted only one of the 3 sensors. On picture you can see all 3 sensors installed, but it is done only for comparative testing.
To be able to compare the sensors parameters, all it works in triggered measurement mode without averaging. Before comparison sensors were calibrated manually. Calibration was to find minima and maxima indicated in all axes, selecting the gain so all axes has the same range of indications and moving the data ranges so they are symmetric with respect to zero. Occurence of minima and maxima is indicated by the AutoPitLot on-board computer with acoustic way, so you know if all extremes are no longer found and calibration can be finished.
The graph below shows measurement data recorded for 2 turns of the sensor in all 3 axes. Red graphs are for axis X, green for Y and blue for Z. The brightest colors are for MMC3140 sensor, medium for MAG3110 and dark for HMC5883.
