Piotr Esden-Tempski will be hosting the Unmanned Aerial Vehicle Hack Chat this week.

This Hack Chat is at noon PDT, Friday, September 22nd. 

Here's a handy count down timer! 

Unmanned Aerial Vehicles (UAVs) have sparked a ton of interest in both companies and hobbyists. UAVs are used in rescue operations, surveillance, attack missions, and agriculture. The capture of real time images by drones is used in decision making processes like search and rescue, plant nutrients, and irrigation.

One of the controversies around UAV technology is the constantly changing FAA regulations. These regulations limit the use of UAVs, which makes things difficult for hobbyists.

Piotr develops UAV autopilot hardware for Paparazzi UAV. In this chat, we'll discuss how Paparazzi can be used for autonomous flight and the control of multiple aircraft. We'll talk about the types of embedded systems that can be used for these applications. 

Piotr Esden-Tempski is the founder of 1BitSquared and longtime UAV Developer and Embedded Systems Engineer with an extensive history developing Open Source Systems. 

Piotr is also the developer and manufacturer of the 1Bitsy ARM development platform and the Black Magic Probe JTAG/SWD programmer/debugger hardware. 

Piotr is passionate about introducing new people to embedded/hardware development using Open Source tools and solutions that can also be used by professionals for production applications!

TL; DR, in this chat, we'll discuss ::

  • Open Source hardware design for UAVs and drones 
  • All things airborne robotics
  • ARM Embedded Systems 
  • ARM JTAG/SWD microcontroller programming and debugging

Here's the sheet to guide the discussion.

     Sophi Kravitz @Piotr Esden-Tempski welcome!

    Piotr Esden-Tempski I asked Felix Ruess (the Paparazzi project maintainer) to join us but unfortunately he is not available this week. Same thing with Gareth McMullin from Blackshpere Technologies aka Black Magic Debug...

    Sophi Kravitz Could you introduce yourself and tell us a little about Paparazzi (for those who didn't watch the video)

    Piotr Esden-Tempski Hi @Sophi Kravitz thank you for having me. :)

    Piotr Esden-Tempski Hi I am Piotr Esden-Tempski, I am the founder of 1BitSquared an open source Hardware and Software development company with the focus on Unmanned Autonomous Aircraft and Embedded systems. We develop and manufacture hardware based on the needs of open source projects like Paparazzi UAV (, Black Magic Debug (, GDB, libopencm3 ( or 1Bitsy ( We also provide consulting services to companies that are interested in contribution to open source software and hardware.

    Piotr Esden-Tempski I have been involved with UAV since about 2006 and wrote my computer science diploma thesis at Ascending Technologies developing autonomous landing platform hardware and software. Since my thesis I continued to work on elements of UAV systems that were in need of open hardware solutions, founding Open-BLDC motor controller project and later joining the Paparazzi UAV project. I helped developing the Lisa/L autopilot for Paparazzi UAV that was to my knowledge the first commercially available autopilot using the STM32F1 microcontroller. And a series of revisions of the Lisa/M autopilot that continued pushing the reliability and computational power of hard realtime autopilots as well as the use of low cost cell phone market MEMS sensors. (we were using ADXR mems Gyroscopes before that) I have also developed Lisa/S that is the smallest open source full outdoor autonomy capable autopilot.

    msm1089 Hi all, how's it going?

    Piotr Esden-Tempski Through my involvement with open source ARM Cortex based UAV autopilots as well as libopencm3 low-level hardware library for ARM-Cortex microcontrollers, I also got involved with the Black Magic Debug JTAG/SWD debugger project with built in GDB server. 1BitSquared took over the hardware development, manufacturing and distribution of the Black Magic Probe native hardware in 2016 and we work with Blacksphere Technologies on expanding the programming and debug platform further by bringing it to more microcontrollers and keeping Black Magic Debug stable and future proof.

    Piotr Esden-Tempski Ok that is the condensed background story of mine. :)

    johnowhitaker Cool stuff!!

    Sophi Kravitz what is Parapazzi? A little more detail...

    Piotr Esden-Tempski We also have @Rich Burton in the chat, he is the mastermind behind the Hooperfly rotorcraft UAV platform. He is also the developer of the Robot Commander agent software for the Paparazzi platform. and is building fully autonomous self directly rotorcraft swarms based on the Paparazzi UAV platform.

    Piotr Esden-Tempski Regarding paparazzi uav

    Sophi Kravitz welcome new people, sheet for discussion is here:

    Piotr Esden-Tempski Paparazzi UAV is an open source uav platform for autonomous uav

    Rich Burton Paparazzi UAV (Unmanned Aerial Vehicle) is an open-source drone hardware and software project encompassing autopilot systems and ground station software for multicopters/multirotors, fixed-wing, helicopters and hybrid aircraft that was founded in 2003. Paparazzi UAV was designed with autonomous flight as the primary focus and manual flying as the secondary. From the beginning it was designed with portability in mind and the ability to control multiple aircraft within the same system. Paparazzi features a dynamic flight plan system that is defined by mission states and using way points as “variables”....
