Anyone got any good ideas on how to directly attach a PCB to a strap like a watch band? I'm thinking of some sort of surface mount clip that can be attached to the bottom of the board, and the watch band is passed through two of those clips. I've seen safety pin style clips that mount on the back of those "flashing tie pin" type novelty boards but don't know where to get them, that might be a starting point at least.
Any ideas appreciated.
Thanks Dave.
This link shows how to mount a watchband directly to a housing, not a pcb.

How about a vecro wrist strap and a piece of velcro glued under the PCB.

Or a velcro strap that threads between two slots, one each on the top and bottom edges of the circuit board. (That way you won't need glue.) -mpm
Solder ribbon cable to one end of board and mating connectors to other end of board and cable; wrap around wrist and plug 'em in. (cable doesn't have to actually do anything electrical)
Can't get much geekier than that.

solder a flat wire loop on each end of the PCB,pass strap thru loops. you can bend the loops to allow a flush mount.

a couple of bent pieces of zinc(or gold,silver, etc) plated steel wire soldered through-hole and the strap passed through them.
(like wire jumpers but formed so they have some clearance underneath for the strap. ____________________ _| |_ | | | |

Yeah, that was my original idea, but it turns out I probably don't have the room on the board for the slots top and bottom.
Just realised I might be able to put a slot on the top and bottom of the PCB and then carefully drill holes in the side walls of the slots for regular watch band pins. Might be too fiddly though...

Love it!
Don't know if I'd want to do it, but great idea none the less!
Thanks Dave.
For those stick on safety pin type fasteners check with anyone that makes name badges

I have used 2 methods for this with good results: - pot the board in a block of epoxy having notches and holes for standard wristwatch pins; looks nice but needs a mold. - use large (but thin-wall) heat shrink tubing to attach the board directly to a one piece velcro watch band. I wrapped the board in foam padding first for protection. This is really quick and easy and was actually more comfortable to wear then the potted version.
Why not just get one of those large face wristwatches at a flea market. Take out the guts and put you PCB into it? Even cut out the bottom if need be, and have a hollow ring with all of the wrist band gizmos already in place and professionally made. Make your PCB circular to fit into it. Or square, if you find a cheap wristwatch with a square face.
