What can you build with a ballpoint pen and some extra parts? [gzip] found himself with a bonus box of right angle switches and other miscellaneous parts and set out to build a joystick. Simple arcade joysticks use switches that are actuated by the movement of the stick and this design embraces the concept. The four tactile switches are mounted on protoboard facing each other with part of a ballpoint pen in the middle. When the pen is moved it presses against one or more switches to close, completing a circuit. For good measure he even incorporated a fire button into the top of the “stick”. Now we just need someone to make this work with a tiny Ms. Pac-Man emulator.
Recently, a friend of ours got married who is a Ms. Pac-Man fanatic. His best man set out to fulfill the groom’s dream of owning a Ms. Pac-Man cocktail cabinet. The problem is that the unit he was after was selling for $2500. It’s great to buy the real thing (and with guest contributions he did,) but if it’s not available consider building your own.
[Alex] has put together a comprehensive guide for building a MAME cocktail cabinet. Unlike the mini-cabinet we saw last week, this is intended to be used sitting down and features controls on more than one side. His guide details the use of an original arcade CRT or an LCD flat panel, high-end controls via an I-Pac 4 controller, and a PC running MAME and MaLa software for Windows. The result is a professional looking build with controls on three sides of the table.
