Light pad - Light box

thingiverse

Today I am uploading my daughter's lightpad, which I built especially for her. The lightpad measures 47cm in length, 35cm in width, and 2.5cm in height. The work surface is perfect for drawing A3 format artwork. For this project, I used a variety of materials beyond printed elements. These include: 1) Aluminum profiles from an old advertising stand - the external dimensions are 17mm by 27mm, with a wall thickness of 1mm. 2) Two layers of 3mm thick transparent plexiglass, which provides hardness and clarity. I placed a sheet of tracing paper between them to diffuse the light. In hindsight, I think milk-colored plexiglass would be an even better choice. 3) A 3mm thick furniture back board adds stability and support to the structure. 4) A 12V DC capacitive touch sensor switch allows for effortless on/off control with a simple touch. 5) The 12v DC led strip lights provide soft, ambient lighting that can be adjusted in intensity using the dimming option. 6) I repurposed an old router's power socket and 12V power supply to keep things tidy. Inside the lightpad, I carefully glued letters printed from fluorescent filament. When the lights are turned off, a cheerful message appears on screen:). The switch also features a convenient dimming option, allowing you to adjust the backlight intensity to your liking. The corner opposite the switch and socket is designed for easy access.
