 PVC Pipe Belt Sander PVC Pipe Belt Sander A PVC pipe belt sander is a handy DIY tool made using PVC pipes, a small motor, and a sanding belt. It’s an affordable and portable alternative to commercial sanders, perfect for hobbyists, woodworkers, and DIY enthusiasts who want to smooth, polish, or shape materials. Why Build a Belt Sander with PVC? Low Cost: Uses cheap PVC pipes and fittings. Lightweight & Portable: Easy to carry and store. DIY Friendly: Can be built at home with basic tools. Customizable: Design can be adjusted for small or medium sanding projects. Materials Needed PVC pipes & fittings (for the frame) Small DC motor or drill machine motor Sanding belt Pulleys/rollers (PVC or wooden) Bearings Switch and wiring Power supply (adapter or battery) How It Works The motor rotates a pulley connected to a sanding belt loop.

 pH Sensor pH Sensor A pH sensor is an electronic device that measures the acidity or alkalinity of a solution. It is widely used in laboratories, agriculture, aquariums, food industries, and DIY projects where monitoring water quality is important. How a pH Sensor Works A pH sensor typically consists of a glass electrode that measures hydrogen ion concentration in a solution. The sensor generates a small voltage that corresponds to the pH level, which is then read by a microcontroller (Arduino, Raspberry Pi) or a digital meter. pH < 7: Acidic solution pH = 7: Neutral solution pH > 7: Alkaline solution Applications of pH Sensors Agriculture: Monitoring soil and irrigation water pH for better crop growth. Aquariums: Ensuring safe water conditions for fish and plants. Food & Beverages: Quality control in brewing, dairy, and soft drinks. Environmental Testing: Checking water quality in rivers and lakes.
