How to make a giant whiteboard for $14 (plus nails)

Summary. A short LessWrong post shares a cheap DIY hack: a 4x8 sheet of "smooth white hardboard" from Home Depot or Lowe's, cut in half for easy transport, costs about $14 and works as a functional whiteboard when mounted on a wall. The author warns the material chips easily and that writing left too long becomes hard to erase, though whiteboard cleaner, alcohol, or over-marking with another marker helps; buffing with turtle wax before hanging reportedly improves stain resistance. Mounting was done with drywall anchors and washers, though the author flags this as likely overkill and notes Command strips failed to stick to the panel material, so a better low-damage renter-friendly method is still an open question.
On the note. If you're worried about drywall anchors as a renter, French cleats or a picture-hanging rail screwed into studs (rather than the panel itself) would let you take the board down without patching a grid of holes — you only need to patch the rail's mounting points, not every corner of the panel. This is basically the same genre of move as the The mosquito bucket of doom works — LessWrong post: a trivial-cost material hack that outperforms the expensive branded version (real whiteboards, retail mosquito traps) by orders of magnitude on cost-per-unit-utility.
