How it works and how to install
The fuse contains a metal wire that instantly melts when the electrical current exceeds 20A, interrupting the circuit and protecting the device from damage. For installation, disconnect the device from the power supply, open the fuse compartment, remove the blown fuse, and insert a new one from the set. The standard 5x20mm size ensures compatibility with most fuse holders in electrical and electronic devices. You can check the fuse's status by looking through the transparent glass tube.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
