Join Hack Chat

Asaad Kaadan is an electronics engineer from Seattle, WA.  He builds robotics and high-end camera controllers for Freefly Systems by day and by night, he designs Hexabitz electronics prototyping modules. He holds a PhD and Masters in Electrical Engineering from University of Oklahoma and a Bachelor degree in Electronics from Aleppo University.

__________________

We will talk about the new modular electronics architecture used in Hexabitz where each module has its own microcontroller and modules connect together in a decentralized, wired-mesh network. The design offers more modularity and scalability than bus-based systems and is implemented with off-the-shelf small ARM Cortex-M0 MCUs using serial ports and DMAs.

How does the system cope with a module or a comms line failing? Does it dynamically reroute? is there a timeout? Are the participants alerted that the system is limping?

  Are you sure? yes | no

From the video it looks like the configuration is "found" once and after that the routing is static, is that the case? And is the system communicating in a active redundant way, ie along more than one path at a time?

  Are you sure? yes | no

How did you choose which modules of your modular prototyping platform to develop first?

  Are you sure? yes | no

What made you want to incorporate biomimicry into your hardware prototyping platform?

  Are you sure? yes | no

Any recommendation for modular HW involving high speed and throughput sub-systems? We have used CAN and RS485 for different node based complex systems, but if video or lidars get into game then Ethernet and USB are still the only ones to go?

  Are you sure? yes | no

Are there any use cases you anticipate a wired mesh network being more useful for solving than a simple one brain chip approach?

  Are you sure? yes | no

Why the chosen license as opposed to GPLV2 ? The project resembles a software comma library after all?

  Are you sure? yes | no
