Podcast Notes
- Scott Shawcroft of Chickadee Tech (see Figure 1) is our guest on this weeks podcast. He is working on a modular flight control system called Polystack. It has 13 different boards that can be stacked together. Similar to shields for the Arduino platform. See Figure 2A and 2B.
- Scott is down here in Houston visiting MacroFab to see his production-run being built, while working on his test fixture with us (See Figure 2).
- Scott is a member of the Seattle Multi Rotors community.
- The software stack is based of off Beta Flight which is a fork of Clean Flight which is a fork of BaseFlight. The very first flight controllers were based of the Wii Nunchuck. Scott uses custom pin mappings and uses a larger ST MCU which required another fork.
- Scott got into Quadcoptors after watching the video Crash Session!!! His first quad was from Flite Test.
- The Tiny Whoop is a small FPV quad that is easy to build.
- Chickadee Tech is Scott’s first step into the hardware world. His first build was a lap timer using the radio strength signal. Scott self-taught himself KiCad.
- AutoDesk purchased CadSoft from Farnell. Autodesk EAGLE – The perfect tool to designing stuff for PIC16MEGA32u4.
- The FR4 Machine Shield we mentioned in a previous podcast has a Kickstarter now. It’s an Arduino “shield” CNC machine. It comes on a 18” x 22” PCB panel. Motor controllers are called “Swap Drives”. Driver chips are on PCB cards that go into edge connectors.
- The FAA released new rules for operating rules for unmanned aircraft (Quads).
