Sometimes I have multiple razors going, but I can't tell which one is the sharp one before I pick it up, or other times there is a toothbrush that I don't know when I began using. For items such as these, where you like to count the number of uses, I think it would be nice to have a counting strip you could attach to the device, or maybe just leave on the counter.
Such a strip would have eight or ten cutout holes, and underneath each hole, a pull tab would allow you to alternate between off or on. That is, there is a small sliding strip of cardboard underneath each hole, and you can slide it laterally to alternate the hole colour between 1 and 0.
I think this is advantageous over a pencil because: a) it's inconvenient to carry a pencil sometimes, b) you don't have to erase anything, c) you could make a mini version of this and stick it on to whatever you need to keep track of.
Yo.-- Cuit_au_Four, Jan 08 2007 interesting. would a row of dots/numbers hidden by those little grey paint blobs on scratch cards work?-- po, Jan 08 2007 Yo.
Cool, this lets you count to 1023 before you change toothbrushes, that's like nearly a year if you brush 3 times a day.
pity 9 out of ten people can't count in decimal.-- Custardguts, Jan 08 2007 oh, ahem.
yo.-- Custardguts, Jan 08 2007 yoyo
this needs a better title.-- po, Jan 08 2007 kinda raises the image of a one-piece strippers' outfit, doesn't it?-- Custardguts, Jan 09 2007 I thought about scratch cards, but then you couldn't get the paint back on, so it wouldn't work the way I'd envisioned it.-- Cuit_au_Four, Jan 09 2007 random, halfbakery
