Item identification

multimeter

this is a digital multimeter. the average homeowner could use this to check electrical outlets to verify function, test batteries, probe rectal temperature, ect. if at all possible, kill yourself with it. would be an excellent news story

More specifically, a cheap (around $20) multimeter with a temp probe currently plugged in instead of voltage probes. Might be useful. If there are some other probes around for it a common useful function would be the audible continuity function (red setting, lower right of knob) as it simply means the meter will beep when it sends a trickle of power all the way through something. Use for diagnosing broken power cords and the like.

>>921629
he can always just buy probes, they are like $5

>>921620
protip for newfaggots, VΩmA indicates it's a multimeter (hence V for volts, Ω for ohms, mA for miliamps), as opposed to just a voltmeter/ohmmeter
Looks like that measures temp too.

>>921720
Looks like a multifunction blu ray/DVD recorder to me.

>>921755
I was thinking that too. Possibly even a Sony

>>921620
As many others: multimeter. Can't imagine a woodworking-related case where one would be useful

>>921801

There has to be a power button somewhere.

>>921803
Some people have used them to read wood moisture content but I think it would be easier to buy a proper ting.

I don't know why my pictures are rotated tho

>>921855
Clamp meter. Put it around a wire to read the current

>>921856
Insulation tester.

>>921805
Perhaps look for something green or blue. The record button is usually red.

>>921853
Microwave detector. Newer model still on market: http://www.sairem.com/measurement-48.html

(Just put the device markings into Google you dolt.)

metal stake for slaying metal vampires
this one is for relatively soft metal vampires

>>922357
Pretty sure Megger's a brand name. But yeah, that looks like an insulation/earth bond tester. Handy for PAT testing, if where you are has a requirement for it.

If I were to use OP's tool to test for a shitty circuit board, I won't get electrocuted, will I? My electric water heater keeps tripping the circuit and I think that maybe 1 of the 2 poles is messed up. I don't want to start fucking with the heater until I'm sure it isn't the circuit breaker.

Watch your hands as you measure the voltage, and you will be fine

Make sure you're using probes with baffles on the probe to stop your fingers sliding down onto the metal, and shrouds around the plug so there's nothing exposed where it meets the meter.

>>922741
Is it hollow or brass all the way through?

>>922881
it's solid, not 100% it's even brass but it is soft metal

>>922794
do they even make ones without those guards?

>>921720

Was by my father-in-law during holydays. He was physics teacher, and had a nice collection of physics instrument, but we could not identify one (he has memory trouble now...).
It looks like an optical device : it has a small glass window, with a filamanet behind. Two electrical binding posts are available to connect the filament. Two screws seems to allow adjusting horizontality.
What is this instrument for ?

Another photo.
A gratuated knob allow to adjust filament alignement.
A tool is present in the box (to place a new filament in the device ?).

The brand is "The Cambridge Scientific Instrument".

>>922741
probably just a key for something. it reminds me of a water bib key, but its not. just go around sticking it in holes until you find one it fits into. maybe it opens a secret passage to wild riches.

>>923296
I always cut them off as they often get in the way
