    GeigerLog

    GeigerLog

    Python program for Geiger counters and Environmental Sensors

    GeigerLog is a combination of data logger, presenter, and analyzer, and is now released in version 2.0.0! New: Gamma Spectra - can now be displayed, calibrated, and evaluated in GeigerLog! Based on Python (Version 3), it runs on Linux, Windows, Macs, Raspberry Pi, and other. GeigerLog is WiFi-enabled for servers and clients; it can be monitored by SmartPhone. Initially developed for Geiger counters, it is now a more universal tool, which equally well handles data like temperature, air-pressure, humidity, CO2. Continues to support Geiger counters like GQ Electronic's GMC-300/500/600 , RadMon, RadPro, Gamma-Scout, audio-click and other low-cost Geiger counters, IoT devices, I2C based sensors, GQ EMF devices. GeigerLog reads data from devices, saves them to databases, prints to screen and plots as auto-updated, customizable graphs. Quality control using Statistics, Scatter, Poisson, FFT & Autocorrelation, and more. The Raspberry Pi 4, 5 qualify as GeigerLog hosts.

    footmouse

    footmouse

    Allows Linux users to use a HID compatible USB foot pedal as a mouse

    The foot pedal emulates a mouse in conjunction with up to 4 modifier keys, ALT, CONTROL, SHIFT and ESCAPE. Functions available are Left Click, Double Click, Right Click, Cursor Up, Cursor Down, Cursor Left, Cursor Right, Wheel Scroll Up, Wheel Scroll Down, Middle Click, Page Up, Page Down, Window Select, Close window, Minimise window and Null (define an option that does nothing) - Many foot pedals come with software, often MS Windows only, which allows you to program the pedals to perform some function or other, Footmouse does away with the proprietary software and allows you to assign Mouse commands to a pedal or a pedal with a modifier key. All functions can be assigned as you require. Designed principally to help people who have difficulty operating a Mouse but able to operate a foot pedal. By its very nature, moving about the screen is slow compared with using a mouse but it does the job, if you can't use a mouse. Note: new VEC Infinity in-USB3 foot pedal not supported.

    serialLCD ATmega8 (ArduinoBased)

    The serial LCD module using ATmega8 along with easy arduino library.

    serialLCD is Arduino based open-source project. It contains ATmega8 with given firmware file & the arduino library. The ATmega8 can be replaced by ATmega168/328. ATmega8 uses its 8MHz internal oscillator to reduce hardware (atmega8 no-xtal bootloader is used). The arduino library uses SoftwareSerial internally to communicate ATmega8 via digital pin 6 (only for uno/duemilanove or clone with atmega8/168/328, not for mega & due). Only one wire simplex serial communication at baudrate 9600 is required to communicate with serialLCD module. The library & firmware file is released in public domain as open-source project. Feel free to edit/improve/share it. *** Raspberry Pi python library added. video available on youtube at: http://youtu.be/adNOWREWuL8

    GROWbox Supervisor System (GROWSS)

    GROWbox Supervisor System (GROWSS)

    Automated Plant Environment Growing System using Raspberry Pi

    GROWbox Supervisor System (GROWSS) is a grow box or grow cabinet environmental controller. GROWSS uses a Raspberry Pi (RPI) & Grove sensors to monitor and control the environment in your grow box or cabinet. Environmental factors such as temperature, humidity, soil moisture, & smoke (from fire) are monitored and displayed on a terminal connected to the RPI & on a mobile app. GROWSS also controls the exhaust fan and grow lights based on the time interval (ie. 12 hours on/12 hours off) & from environmental factors, temp & humidity. The environmental values are saved to the local storage every 15 minutes and when an alarm is present. Hi & low values are also saved. The LEDs on the case & the mobile application indicate if there is a high/low temp alarm, hi/low humidity alarm, soil moisture alarm, or smoke alarm. A speaker (buzzer) is activated on the case if there is a smoke alarm. 2 other LEDs indicate if either the exhaust fan is on or if the humidifier is on.

    RaspberryLight

    Make your Raspberry Pi to a Wi-Fi controllable LED Light

    Make your Raspberry Pi to a Wi-Fi controllable LED Light using LED stripes with WS 2811 controller. This software enables the raspberry to provide a web server interface (HTTP / Rest) for controlling the connected LED stripe. That project bases on the WiringPi lib, Indy for Lazarus and also on the Tinkerforge bindungs for Lazarus. The Stripe must be connected with the Tinkerforge Masterbrick and the LED-Stripe bricklet. WiringPi is used to control the GPIOs for some feature and Indy (Internet Direct) is used to support all network feature like UDP-broadcasting and handling the HTTP-requests. The development platform is Lazarus.
