A wearable WiFi security-testing platform, disguised as a wristwatch.
Custom ESP8266 hardware inside a repurposed SKMEI watch case, running a modified build of Spacehuhn's ESP8266 Deauther. This repository is the complete build: KiCad schematics, bill of materials, 3D enclosure model, and adapted firmware.
Orbit turns a raw ESP-12E/F module into a wrist-worn WiFi security testing tool. It presents a small on-device menu — Scan, Select, Attack, Packet Monitor, Clock — navigated with three tactile buttons, and reports live channel activity on a 128×64 OLED.
| Form factor | Modified SKMEI digital watch case |
| MCU | ESP-12E / ESP-12F (ESP8266) |
| Display | 0.96" I2C OLED (SSD1306, 128×64) |
| Input | 3× tactile buttons (Up / Down / OK) + Flash + Reset |
| Status LED | WS2812B addressable RGB |
| Power | 3.7V single-cell LiPo |
| Firmware base | Spacehuhn ESP8266 Deauther (MIT), re-pinned and rebranded |
This repo covers both halves of the build:
hardware/— KiCad schematics for the main board and a standalone FT232RL-based flasher board, with PDF/SVG exports so nothing requires KiCad installed to review.firmware/— the Deauther source, adapted to Orbit's exact GPIO map, plus a prebuilt binary in Releases.
Warning
Orbit can interfere with wireless communications (deauthentication, scanning, packet capture). Use it only on networks you own or are explicitly authorized in writing to test. Unauthorized use may violate wireless regulations (e.g. FCC Part 15 in the US) and computer-misuse laws in most jurisdictions. See Legal & Ethical Use.

Full KiCad source lives in hardware/. PDF and SVG exports are included alongside the .kicad_sch files for quick review without installing KiCad.
| Board | Purpose | Files |
|---|---|---|
| Main board | Orbit watch — ESP-12E, OLED, buttons, WS2812, battery | hardware/orbit-main-circuit.kicad_sch · PDF · SVG |
| Flasher board | FT232RL USB-TTL programmer for initial flashing | hardware/orbit-flash-circuit.kicad_sch · PDF · SVG |
Note: on the flasher board, UART is crossed as expected for serial programming — FT232 TXD → ESP RXD0/GPIO3, FT232 RXD → ESP TXD0/GPIO1.
Orbit's firmware is a modified build of spacehuhn's ESP8266 Deauther (MIT License), re-pinned to Orbit's GPIO map with a rebranded boot screen. See NOTICE.md for the exact scope of modifications and attribution.
Grab Orbit-firmware-v1.0.bin from Releases and flash directly — no build environment required.
git clone https://github.com/shasradha/Orbit.git
cd Orbit/firmware/Orbit-Firmware-Source/orbit_deauther- Open
orbit_deauther.inoin Arduino IDE 2. - Install the ESP8266 board package: Tools → Board → Boards Manager → search "esp8266".
- Select Generic ESP8266 Module as the target board.
- Compile.
Use the included flasher circuit (FT232RL-based) or any USB-TTL adapter:
esptool.py -p <PORT> -b 115200 write_flash 0 Orbit-firmware-v1.0.binCompiles cleanly against Orbit's custom pin configuration. Not yet flash-tested on physical hardware after this specific pin remap — testing reports and issues are welcome. The underlying hardware, OLED wiring, and button layout have been verified working on this exact board (see Gallery).
A 3D reconstruction of the Orbit enclosure, built from real device photos and refined in Blender, is available for interactive preview:
This is an AI-assisted reconstruction for visual reference only — it is not dimensionally exact. The Blender source file is in hardware/3d/ for anyone who wants to inspect or rebuild it.
