We are developing a set of Delphi components to communicate with a ModBus PLC over TCP/IP. The library provides components to implement both a ModBus master and a Modbus slave, and is based on the Indy component set (both Indy 9 and 10 are supported) De source code of the project has been moved to GitHub!

This software + hardware is designed to map lighting intensity in a serie of successive locations. It uses a light dependent resistor to sense light level that was designed to measure light uniformity in an indoor seedling rack and can be useful for lighting devices designers, stage lighting, etc ...

MultiMon Manager (MMM) is a Library to handle, detect, enumerate and control multiple Monitors under Windows, written in Object Pascal. MMM is capable to use the Windows Low-Level Monitor API including VESA Monitor Control Command Set (VESA MCCS). You can use MMM to read out your Monitor Capabilities like physical Resolution, supported Resolutions and Refresh Rates, Vendor Informations, Firmware Version and current settings like Brightness, Contrast, Gamma and so on. You can use MMM also to send MCCS Commands to your Monitor to turning it into Standby, wake it up again and change its Brightness, Contrast or Gamma Settings. Note that this is done directly by the Monitor and NOT the Graphics Card. You can't believe that? Have a look to your Monitors On-Screen Display when changing Settings with MMM! Furthermore, MMM has methods to place a Window exacty to a Monitor relatively to global Desktop Coordinates and taking Screenshots from a Monitor Content.

PowerStateControler goal is to: 1. schedule computer shut, sleep or hibernate mode; 2. disable sleep mode for laptop computers if user wants to execute a task without staying in front of computer (example: download, backup...). 3. Power monitor off.

k10ctl is an AMD Family 10h (aka K10) P-State, frequency and voltage modification utility . Its main purpose is overclocking and / or "undervolting" the CPU and to configure Cool'n'Quiet settings.
