OSpectrometer
Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research.
OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs.
- Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values
- A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen)
- The whole spectrum or a specific part of the spectrum can be selected and scanned
- Front camera is used to sense the reflection from the target object
- Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum
- The result can be saved and shared
- Works offline, no need to connect to any network or internet
Cardiographer
Cardiographer: Your Heart at Your Fingertip
Transform your iPhone into a personal heart monitor with Cardiographer—an innovative app designed to provide real-time insights into your heart health.
Key Features:
Real-Time Cardiograph: Experience live, high-quality plots of your heartbeat.
Accurate Heart Rate Monitoring: Get precise heart rate readings, powered by advanced algorithms.
Front Camera Technology: Say goodbye to the limitations of back-camera apps—no flashlight required.
On-Device Computation: Data is processed securely and privately on your iPhone.
Works Offline: Measure your heart’s rhythm anytime, anywhere without an internet connection.
How It Works:
Cardiographer employs innovative technology by displaying a specific color (optimized to green for stability) around the front camera, while simultaneously capturing reflected light from your fingertip. Using advanced mathematical and physical methods, it filters and extracts accurate heart rate and cardiograph data.
Why the Front Camera Makes a Difference:
Unlike other apps that rely on the back camera and flashlight, Cardiographer eliminates these drawbacks:
No Flashlight Dependency: Poor illumination and changing spatial configurations between the back camera and flashlight (varied across iPhone models) often lead to inaccuracies in other apps.
Enhanced Illumination: By leveraging the front camera, Cardiographer illuminates the finger with a consistent, calibrated green light, achieving better precision and stability.
Superior Quality: This innovation enables higher-quality cardiograph plots and more reliable heart rate results.
Why Choose Cardiographer?
Whether you're tracking fitness, managing stress, or curious about your heart health, Cardiographer sets a new standard for convenience and accuracy in heart rate monitoring.
Important Disclaimer:
While Cardiographer provides high-quality cardiograph plots and reliable heart rate measurements, it is not a medical device and should not be used for medical purposes on patients. This app is not intended to diagnose, cure, or treat any illness or disease. If you experience any issues or concerns with your heart, always consult a qualified medical professional. Cardiographer is designed for informational and general wellness purposes only.

Serial Positioner
Designed for controlling 3D motion over serial port.
Serial Positioner is a basic application developed to communicate with connected USB-Serial peripherals and control devices with serial port.
It only transmit/sends data over serial port, there is no receive function.
Sends string data packets with three different variable with no size limit at the application side.
Data structure is set by the Intuitive controller tools.
Its flexible - delimiters can be changed, so it can be configured to work with your specific serial device.
Example usage scenario including 2D microscope stage controller application (C++) is given at support website.
