 SmartCoaster

Operation: coaster units form a wireless mesh network. Info hops from unit to unit until it reaches the router. The router connects to a computer’s USB port and centralized the coasters info. Data can be uploaded to cloud in real-time for remote management.

Project Status: prototype, not in development

Technology highlights:

• Sensor: Load Cell (salvaged from kitchen scale)
• Interface: Instrumentation Amplifier from TI
• Microcontroller: PIC18F
• Wireless module: nRF24L01+ or Bluetooth
• Battery: Li-ion 3.7v 130mAh (salvaged from toy helicopter)
• Enclosure: designed in SketchUp, 3d printed by Shapeways
• PCB: designed with Eagle, fab by OshPark

MICO

Purpose: I wanted to start up my car’s engine from indoors during the sub-zero Minnesota mornings. I installed a remote starter in my car but found the range was insufficient. I then took on the challenge of hacking my car to make it start with a phone call.

Operation: MICO is circuit board compatible with the Arduino prototyping platform. It implement a mobile Interactive Voice Response System with controls. Think of it as an answering machine that take commands via the keypad. Instead of “pressing 0 for operator”, you would type the password and 0 to start the vehicle.

Project Status: In Production, more info at: http://HelloMico.com

Technology highlights:

• DTMF Decoder IC with discrete op-amp for signal amplification
• Mobile phone interface via Audio Jack
• Support Answer/End Call actuation.
• MicroSD card to store voice prompts.

RECAP Audio Adapter

Overview:  RECAP is an audio adapter for smartphone call recording. It taps the signals between phone and headset and creates a “copy”of the signals so user can record call into a second device: PC, Voice Recorder, or another Android / iOS phone or tablet.

Project Status:  in production, more info at http://RecapMyCalls.com

Technology:

• Circuit: Analog circuit design using signal amplifier.
• CAD: SketchUp software as the 3d modeling software.
• Enclosure: ABS, Up Mini 3D Printer.

OpenLoggage

Project Status: prototype, open source http://OpenLoggage.com/main

Technology Highlights:

• Microcontroller: Atmel 328p, Arduino boot code
• Sensors & Peripherals: accelerometer, light sensor, Real-Time Clock, li-ion charge circuit
• Low-Power Design: 99% better than Arduino Uno

ChargIntel

ChargIntel (2014): vehicle battery predictive analysis with mobile phone and push notification. BLE, ARM, Android, iOS

Project Status: prototype, not in development

Technology Highlight:

• Microcontroller: Nordic  nrf51822 (Bluetooth Low Energy with an ARM Cortex-M core)
• Bluetooth Low Energy, iBeacon for push notification.
• Health of vehicle’s charging system (battery, alternator and starter) determined via predictive analysis.
• Smartphone app provide cloud connectivity
