Hacker Home Security Door Sensor v0.1

Ultra-low-power asset tracker with STM32L433 MCU host, CAM M8Q concurrent GNSS engine, EM7180+MPU9250+MS5637 for absolute orientation and altitude, and ESP8285 wifi for connectivity. Separate UART connections between host and modules, control of power enable via GPIOs or serial commands from host, RTC backup batteries and power from single-cell LiPo.

DIY version of the Frantone Vibutron. Layout by storyboardist/Effects Layouts

A first try, based on http://kempbros.github.io/antennas/Patch_Antenna_Generator/

Does not work as intended, center frequency is about 4.95 GHz. May be usable for 5 GHz WLAN :-)

E-Paper Badge with Teensy LC designed in KiCad

E-Paper badge designed in KiCad to connect Pervasive Displays 2.15" E-Paper (E2215CS062) to Teensy LC. (Teensy 3.2 is also compatible). Based Teensy E-Paper Shield by Jarek Lupinski in EAGLE.

KiCad PCB design files:

• repo: kicad-teensy-epaper
• commit: Reworked layout for aesthetics [0a40263]
• requires KiCad library wickerlib by Jenner Hanni of Wickerbox Electronics for the 34-position FPC connector that the e-paper display plugs into:
  • CONN-HEADER-FH34SRJ-34S-0.5SH.kicad_mod

Battery Power

• These products are used to power the badge from a battery.
• LiPo battery charger add-on for Teensy 3.1 from Pesky Products on Tindie
  • WARNING: The trace between VIN and VUSB must be cut! Here is an demostration of cutting the trace on Adafruit Learning System.
• Lithium Ion Polymer Battery - 3.7v 500mAh from Adafruit
  • Initial capacity chosen for a good trade off between weight and power. I have not yet measured how long it will run with different capacities.

Source Code

• uses EPD215 Arduino Library by Jarek Lupinski for his E-paper Teensy Shield
• requires pinout modification:
  • EpaperQuoteDisplay.ino
  • EPD215 epaper( 17, 16, 14, 15, 13, 11 );
