As anyone who owns one of the original PowerBooks knows, the I/O port door with its latch/tab and power button behind it isn't the smartest of designs. Since I got my PowerBook 170 back in 2001 I've been alternating between using it without the door (not that pretty), with a door with the tab intact (too hard to open) and most recently with a door without the tab and a piece of double sided tape in its place (works for a while but, naturally, the tape slowly collects dirt and loses its stickiness). So, for some time now I've had the idea to upgrade it to use a magnetic lock
I started out by cutting a small piece of metal out of a steel sheet, and used the tip of an iron to slowly melt it into the port door in the area where the latch/tab used to be, and then covered the piece with the plastic that was forced up in the process.
For the magnet part I used a neodymium magnet from a broken hard drive, which I snapped to a size suitable for the hole where the locking tab usually goes (a very tricky process considering the brittle nature of neodymium magnets, but I finally ended up with a relatively clean piece). For now I've just fitted the magnet inside the hole without covering it with plastic, but I might do so in the future.
Anyway, the upgrade turned out really good, with just the right force between the door and the magnet to keep it in place while still making it easy to open.
I've attached a video of the result and a few photos of the process.
