V-shaped plastic welding staples to repair cracks in internal corners. To repair a crack, place the tip parallel to the crack line.

Module with liquid turbidity sensor. It allows you to measure the amount of suspended particles in a liquid. The sensor can operate in two modes: digital and analog.

The battery tester is a compact device that allows you to check in a very simple and quick way whether the batteries or rechargeable batteries we use are functional. Our devices require good batteries or accumulators and we are often not sure if our equipment has the right power supply to withstand, for example, during a trip or celebration. Nothing easier, you can check it using a tester.

The inverter is powered by 12V DC, it generates alternating current to supply electroluminescent wires that glow under the influence of high voltage supply. Adafruit 832

Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects). Adafruit 813
