eVscope Data Storage & Memory: Uploading Data

Follow

Key Takeaways

    • The eVscope storage (also referred to as “eVscope memory”) only fills up when you use Enhanced Vision or Science Observation modes;
      • saving pictures of your observations does not fill up the eVscope memory;
      • the storage capacity of the eVscope allows for up to 7 hours of Enhanced Vision mode. In Science Observation mode, the shorter the exposure time, the more frames it takes, the faster the memory will fill-up;
      • even with full memory (100% data storage used), the eVcope will continue operating normally, and you will still be able to save your pictures. However, you will not be able to take part in community events or citizen science campaigns;
  • Storage information can be found under the “User” tab of the app;
  • Uploaded data help us create a better user experience, improve our app and allow you to take part in scientific discoveries or community events.

While using the Enhanced Vision mode or the Science Observation modes, raw data (frames) of the objects you are observing are automatically saved in your eVscope memory. The eVscope storage information is found under the “User” tab.

Note: under the “User” tab you will also find the battery charge gauge, the eyepiece focus helper button, and the button to take a dark frame.

The beautiful pictures that you save during all your observations are not saved on the eVscope but rather on your smartphone, so uses your smartphone storage space instead.

In order to free up (reset or empty) the eVscope storage, it is recommended to regularly upload the data to our servers. To do so, follow these simple steps:

Upload process

  1. While your smartphone is connected to your eVscope, simply go to the user tab on the app (this can be done once you have returned to the comfort of your home);

  2. If there is data stored in your eVscope, tap on the “UPLOAD DATA”, otherwise the button will be grayed out;

  3. A popup window will appear asking you to enter "Wi-Fi information". This can be your home Wi-Fi network or you phone hotspot information depending on which you want to use for the upload.

    The SSID is the name of your network - it is case sensitive

    It is possible to use the same device you used to connect to the eVscope to upload the data, although it is usually easier to use a different device

  4. After clicking on "Validate", the eVscope LED will turn from the usual red color to blinking bright green - this means that the eVscope is trying to connect to your selected network. At that point your device will no longer be connected to the eVscope and information like its name or storage usage will no longer be accessible byt the app. The LED will blink in a regular pattern:

    The eVscope LED will then either:

    • turn yellow and blink rapidly between 1 and 6 times and then stay solid for 5 seconds. The number of blinks indicates how much data there is to transfer, the higher the number of blinks the more data there is.

    • or turn solid orange which means an error occured.

      8 times out of 10 it will be a typo in the network name (SSID) or the password, but other factors may be causing this: maximum number of allowed devices on the network reached, MAC address filtering in place or Wi-Fi channel incompatibility. For that last issue, restarting your router / device Wi-Fi connection will solve the issue. For the other two issues, you will need to connect to your home wifi network with another device to enable more devices or add the eVscope MAC address to the list.

  5. Optional step: to check if everything went smoothly, reconnect your phone to the eVscope. Go back to the User tab of the App. After a few minutes, the amount of data in the storage section should indicate “Storage: 1% used”. The transfer was a success.

Tip: regular users usually go through this process at the end of each night of observation or, at the very least, every time their eVscope data storage approaches 20%. This guarantees they are ready whenever they want to participate in citizen science campaigns or community-based observation events.

Tip: starting the upload process just before going to bed and leaving your eVscope on during the night should allow the data transfer to complete overnight.
