(Somewhat) apropos yesterday's article on tinkering: I wanted a simple setup to mount my Treo phone/pda in the car. None of the kludges for sale impressed me favourably, all being expensive/clunky/both or worse.

Being the Dismantler and Recycler Of Crap that I am, I have a few dead hard disks sitting around. Dead hard disk = two large and strong magnets, iff you manage to get them off their backing without breaking the brittle material. Sometimes I do manage, sometimes I don't.

So here's my ghetto mount: a fat magnet in heatshrink tubing, embedded in the back of a slab of coreflute which is stickytaped to the car dash. The Treo-side consists of a bit of thin sheet metal (was once part of a floppy drive housing) taped to the back of the treo with super-thin packing tape.

The hard disk magnet is easily strong enough to work through one layer of heatshrink, coreflute, the silicon glove and the packing tape. With the packing tape no irreversible mods to the Treo are necessary.

Simple, neat and zero-cost. I like that.
