Grant Custer published a build video and full parts list for his tabletop touch computer, totaling $574:
- Parts: $200 Hisense 55" TV (Best Buy), $164 43" IR touch frame (Walmart), $80 anti-glare protector, sidewalk-sourced plexiglass, $330 mini PC.
- Key trick: inset the touch frame inside the TV for a flush surface — his earlier 43" setup rested the frame on uneven bezels.
- IR vs capacitive: IR is far cheaper and works well, but triggers slightly above the surface, which hurts handwriting; he may swap to a capacitive overlay.
