Updates

• Titan Yuan BLE TX works

  • all in user guide

  • demo if you want to test BLE onSCuM chips

• eye-safe programmers, but don’t work great

  • but you need 5-10 tries, not consistent even with the same orientation

• Brian update

  • full 3D localization using lighthouse

  • some LDO setting seem to interfere with

  • adding IMU, making smaller board

• Felipe showed that you could integrate MIMSY, IMU, EKF

• we got SCuM to run from Zappy solar panels, including running electrostatic inchworm micro-motors

• 1 ksps (maybe?) from the ADC and 8 bit of resolution (maybe), simple inch-worm motor works

• we need to put all of that together

• goal for the semester: we can gripper (Daniel), tactile stimulators (Dillon), jumpers (Craig), walkers (Hani), etc

  • we should have all 4

  • taction with Eric Paulos, using inch motors to poke people, HCI teams excited

• coordinate with Titan Yuan using app “lightblue”

  • receive 15.4, send BLE

• action item: having Brian create a PR in the CI environment, and merge the code as part of our meeting 2 weeks from now

• hardware wishlist

  • Brian: 3x SCuM+IMU - existing board that Fil designed is fine if they work

  • Titan Yuan : dev board mostly works - would like 2 more

  • Thomas:

    • broken SCuM chips (for demos)

    • broken SCuM+Zappy

  • Thomas: SCuM “chip“ we can run through our reflow oven

  • Thomas: small SCuM boards, coin cell format, breakout, whisker antenna

  • Thomas: 1-2 dev boards, but not necessary for now

  • Daniel: 3-5 SCuM+Zappy chips

  • Alex: easy way to start 15.4 communication, dev board works
