I built my family a giant touchscreen

A developer details the process of building a 40-inch infrared-powered touchscreen called Canvas to act as a family hub. This custom device runs several small applications, including a daily whiteboard, a family calendar, and a chores tracker. The software for these apps was created using the Convex backend platform and the AI code-generation tool Codex. The hardware construction involved sourcing a cheap 40-inch TV, an inexpensive IR touch frame kit, and an acrylic sheet for protection. The project involved overcoming challenges such as assembling the components and calibrating the touch interface, which initially had issues.
