You can build this simple panel bed frame (or just the headboard) with just a circular saw and a drill for about $120 in materials. This free tutorial includes video, step by step diagrams, shopping list and a cut list for Twin, Full, Queen, King and California king mattress sizes.

This bed plan does not require a brad nailer, but having a brad nailer will make building this project easier. You can substitute screws for nails throughout this plan.
Layout the two headboard legs.
Mark a line all the way down each 2x4 leg, 2-1/4" in from the outsides.
Dryfit the panel boards for the headboard on the legs.
Then attach the top 1x8 to the legs, with glue and screws or nails.
Repeat, working downward, for all the 1x8s - just make sure you apply a bead of glue between the 1x8 boards as you go.
