  1. Questions? Please ask already during the talk, so we manage it more easily to send the questions to the speaker. In addition, feel free to join discussion tables on S. Virtual. Happy Open Source Hardware track!
  2. Sounds awesome! Although it seems to be already very modular, would it be possible and feasible to create a free mobile phone without a SOC? So a more x86-like platform with separate modules and chip-set. Maybe something similar to the old phoneblocks concept.
  3. Thank you! Question: How much more money/time did all of that cost than initially planned? Was there are time when you thought "let's stop here"? :)
  4. Maybe I missed that information, but do you offer hardware kill-switches for bluetooth, wifi and other remotely accessible parts of the phone?
  5. Non-SOC phone - unlikely, that would get way too big and too power consumsing. Even with an SOC power management is a real challenge.
  6. @Max: I can not talk about this :-) But it is significant. Just to give an idea, we were planning with about 2 year development with a team of around 10 (+/1), we are no going into the fourth year... But giving up? No, no way!
  7. @Peter: Yes, hardware kill switches are there! Three of them, one for WiFi/BT, one for Cellular, one for mic/cam. All three off also disable the sensors and GPS/GNSS.
  8. We start with the new talk now: Alpine Safety with Free hardware/software... Any questions? Feel free to post!
  9. Do you perform on the device computation like edge computing for computer vision tasks?
  10. How do you deal with the situation when there is no signal? Do you use SLAM approach? If yes then how do you deal with computation issue that may arise with resource constraint nature.
  11. As far as I understood this concept, you need a drone and the sending helmet during an emergency? What is the need to install a tracking network station then?
  12. We already started the new presentation: "The Blueslemon project: using short-range wireless networks to localize beacons on landslide surface"... please post questions :)
  13. How would your system react assuming that beacons are not in fixed positions? Have you evaluated it already or plan to evaluate?
  14. If you have many beacons on a floor and no pairing, do you had some/many lost packages in communication? Is the communication still reliable? Does the amount of beacons influence the quality of communication?
  15. This interesting topic continues soon with "BLUESLEMON project: autonomous UAS for landslides monitoring in alpine environment"... Questions welcome!
  16. I see that you've used octmap and I assume that you have used occupancy grid-based approach. How efficient was it, based on what I know it is not that efficient when maps grows larger?
  17. What do you do with remotely driven drones, if you for example enter a valley (like Blaetterbach Schlucht) where you do not have a connection anymore, does the drone act autonomously? Do you have such AI implementation?
  18. Is the computer inside a drone strong enough to do complex AI decisions or do you always need to communicate with a strong server located at the headquarters?
  19. Have you looked into existing similar tools, I know there's a tool from MIT very efficient in terms of result and speed as well?
  20. You talked about path finding. Does it also have a path finding approach for groups of nodes? In old games it was always a problem that group movement blocked single entities, which did not find their way or reacted unnaturally.
  21. Godot is open source... Have you had the chance to contribute to it? How is the community for Godot consumers, do they help you if you have problems getting started?
  22. Next talk starts now. It is all about "Low-cost high-res GNSS technology in combination with RTKLIB for microclimatic monitoring purposes"... Happy to accept questions!
  23. How do you deal with situations like in the case of big buildings which can cause GPS signal issue or occlusion of signals?
  24. Looking at the current climate crisis and movements like "Fridays for future", do you think that micro climatic monitoring and corresponding actions based on data analysis, will become a business and thus enable new companies to make money?
  25. Have you also used map matching for correcting the issue caused in inaccurate positioning? If not have you considered to do so in future?
  26. Next talk is about an Open Hardware Notebook and the Libre-SOC project... Happy listening to Roberto Innocenti talking about "202x Open Hardware Concrete Approach". Discussions after the presentation on S. Virtual
  27. How can someone join your open software/hardware projects? The PowerPC notebook project for instance? Does it make sense as a hardware newbie to get in touch, or what prerequisites exist to get started with open hardware?
  28. What is the main difference between PowerPC and x86 and ARM architecture? Why is the PowerPC better for your projects?
  29. Now we get smart, and talk about "A smart irrigation approach built on the FIWARE open IoT platform"... Questions welcome!
  30. You think for a hobbyist, it would be a good idea to use the FIWARE framework to build a private water irrigation system in his own garden? Or, would it be to complex and other simpler framework a better choice?
  31. This track about OPEN SOURCE HARDWARE is over. You can continue with discussions about the presented topics or just have a chat on our Virtual Village Jitsi System. Please join a table under S. Virtual. See you tomorrow! Have a lovely evening...
