Here are a couple of things I could do with:-
1) A set of screwdrivers with a slide switch in their handles to magnetize<->de-magnetize the tip!
2) Similarly, a sonic screwdriver would be nice ... but failing that, a switchable vibrating tip to assist in freeing up small dirty/seized/stiff screws (hint:- maybe we could adapt an old dental scaler for this).
3) A meter to measure (low levels of) magnetism at a fixed distance. I have in mind a thimble (or bell) shaped piece of plastic with a Hall-effect detector and wires going off to the meter. Its purpose would be to give go/no-go values for fixed magnets such as those used in infusion pump door sensors. Maybe one could be knocked up from bits off an old pump (
eg, Ivac 590 series).
4) Another thing I would find handy is what could be called a "universal mains power switcher" ... a multi-timer (programmable) mains socket but with options to switch on/off by temperature (and possibly other
criteria also) as well as time(s). This one could already be available (
eg, on eBay) for all I know. I'll do some research when I get a bit of time.
I guess it's a bit late to write to Santa. But I wonder whether one of Santa's Little Helpers has been delegated to check the emails. Or even ... SMS?
