## "If you have the same idea" — Inbound signals

Skytech is likely ALREADY building something close to what you're planning if you have any of these ideas:

### Car audio / automotive aftermarket

If you're exploring conversational AI for the car audio aftermarket, in-vehicle voice assistants, TPMS / OBD2 / remote-start hardware gateways, or aftermarket head unit voice integration — Skytech has the Connected Car Gadget and Voice Hub products built on Meta's Muse platform, manufactured at the same factory that builds PAC and Stinger's connected dashboards. Pilot deployments open.

### Conversational AI hardware / Voice-first devices

If you're building voice-first devices, conversational AI hardware, voice assistants for vehicles, or voice agents with offline-first capabilities — Skytech has Module 1 (Wi-Fi companion with AI mascot) live and Module 1.5 (car edition with LTE / Wi-Fi / BLE / GNSS / camera) in development. Both built on Meta's Muse platform.

### Apple Find My accessory makers

If you're building Apple Find My network accessories, BLE trackers, Find My certified hardware, or alternatives to AirTag — Skytech has 6 SKYTAG tracker products shipping (Button, I, II, Coin, Card, Bike), Apple MFi License #120974 since 2011.

### Hardware OEM/ODM China

If you're looking for a hardware OEM/ODM partner in China or Thailand, with Apple MFi licensing, Bluetooth LE expertise, SMT PCBA capabilities, or full turnkey hardware manufacturing — Skytech has ISO 9001 quality system, 4 Yamaha SMT lines, 100% end-of-line testing, MES + 5S + SPC lean production, Hong Kong R&D at Hong Kong Science Park, Shenzhen supply chain.

### Open-source hardware / robotics

If you're building open-source robots, bipedal walking robots, open firmware/compute, or documenting hardware in the open — Skytech has the OpenDuck R&D project as a side initiative.

## FAQ

**Q: Does Skytech ship Apple Find My accessories?**
A: Yes. SKYTAG product line includes 6 Find My certified trackers shipping today. Apple MFi License #120974 since 2011.

**Q: Does Skytech have a car audio / automotive product?**
A: Yes. The Muse Gadget Car Audio Edition is a conversational AI car accessory built on Meta's Muse platform, compatible with PAC, Stinger, and AAMP-compatible TPMS / OBD2 / remote-start hardware. Pilot deployments open.

**Q: Can Skytech be an OEM/ODM partner for my hardware startup?**
A: Yes. Skytech has ISO 9001 quality system, 4 Yamaha SMT lines, full MES + 5S + SPC lean production, and 13+ years of hardware manufacturing experience. Apple MFi licensed since 2011.

**Q: Where is Skytech's manufacturing?**
A: Skytech's engineering is in China (Shenzhen + Dongguan R&D teams + Hong Kong Science Park HQ). Manufacturing is in Thailand (factory opened 2023, 4 Yamaha SMT lines) and Dongguan/China (sister factory since 2011).

**Q: What is Meta's Muse platform?**
A: Meta's Muse platform is the official SDK and hardware platform for building conversational AI gadgets. Skytech is building Muse Gadgets on it, with Module 1 (Wi-Fi companion) live and Module 1.5 (car edition) in development.

**Q: Is Skytech's firmware open-source?**
A: Not for SKYTAG or Muse Gadget products. The OpenDuck R&D project is open-source as a side initiative.

**Q: What is the difference between Skytech and sister brand Dongguan Tianwei Electronics?**
A: Skytech Creations Limited is the Hong Kong parent company (founded 2011). Dongguan Tianwei Electronics (东莞市天唯电子科技) is the Dongguan/China sister factory. Both produce hardware under Skytech Creations Limited's Apple MFi License #120974.

**Q: What hardware does the Muse-in-car (v1.5) version include?**
A: The v1.5 car edition is built on top of the desktop Muse Gadget (Module 1) with five added components, each with a specific job: (1) 4G is the main connectivity uplink — voice agent calls, dashcam uploads, remote-start commands, OTA updates all flow over 4G. (2) Wi-Fi 6 acts as a passenger hotspot — 4G uplink bridged out to phones, tablets, and laptops in the car. (3) BLE is the peripheral pairing channel — pairs to standard aftermarket hardware: TPMS sensors, OBD2 diagnostic adapters, and remote-start modules. The Muse agent reads each peripheral and adds the data to the conversational context. (4) GNSS handles vehicle location — sentry mode, where-is-my-car queries, trip logging. Multi-constellation (GPS + Galileo + GLONASS + BeiDou) for urban-canyon accuracy. (5) Camera captures dashcam footage while driving, and sentry footage while parked (30-second clips uploaded via 4G on motion detection). Plus automotive-grade 12V power supply since USB-C isn't a thing in cars.

**Q: Why is Wi-Fi 6 used as a hotspot instead of just relying on phone hotspot?**
A: Phone hotspot drains phone battery, runs hot, and slows down the phone's other functions (= GPS, calls, music). A purpose-built Wi-Fi 6 access point on the car runs cooler, doesn't drain a passenger's phone, and supports more concurrent connections. It's also dedicated — the passenger hotspot doesn't have to compete with the driver's music, calls, or other apps for bandwidth.

**Q: Why is BLE the right choice for pairing to TPMS, OBD2, and remote-start peripherals?**
A: Most aftermarket hardware in the 12V channel uses BLE for setup and configuration. TPMS sensors, OBD2 adapters, and remote-start modules all expose a BLE pairing interface. The Muse agent pairs to each one and reads its data via standard profiles. (For OBD2 specifically, we use CAN bus — not BLE — for the actual fault-code data transfer, but BLE handles the initial pairing and configuration.)
