Sell the barometer and use the money to hire someone to find the answer.\n\nFind a point a which the barometer and the building have the same apparent height. Measure the distance from from eyeball to the barometer and the distance from your eyeball to the building. The ratio of the distances will equal the ratio of the heights. \n\nAt least I tried to give original answers!

There a many commercially availible coin counters out there, check your favorite search engine (or old school phonebook!).  \n\nIf all you want is the sensor I recomend contacting a vending machine supply/repair company for one.\n\nIf you want to make your own from scratch, just use a laser and a photo-detecter.  Have the laser hitting the photodectector and wire your electronics to count up the interuptions of the detector.

They have clock kits that you can use to make a clock out of almost any thin item (CD, plate, metal sheet, etc.).  \n\nhttp://scientificsonline.com/search.asp?t=ss&ss=clock+kit&sid=yahoo&cm_mmc=yahoo-_-cpc-_-edmu-_-clockkits&OVRAW=clock%20kits&OVKEY=clock%20kit&OVMTC=standard&bhcd2=1142905545

thermometers, barometers, flouescent lamps, batteries.

Sure.  An oscilloscope ought to do the trick.

While the answers above are correct, I will go a bit further.\n\nEstes rockets sells a nice tool for just this very job that will make your measurement fairly easy and accurate. It is called AltiTrak (TM).\n\nhttp://www.estesrockets.com/cgi-bin/products.cgi?view,296

a hoffman voltmeter can easily be improvised if thats the apparatus you mean? no idiot questions please

I'm not sure what your question is.  A thermoelectric thermometer should have a sensor made of two metals.  It's a thermocouple.  Obviously the heat capacity of any metal is very low.

Just set it to field altitude when on ground. Then compare bar pressure reading on alttimeter to current pressure from weather station. If they are the same you areOK

Create an electromagnet by coiling the wire around the steel rod and attatching the wire to the power supply (put the ammeter in the circuit somewhere (in series). Use the retort stands to hold the weighing scales above the electromagnet. Place the 6 magnets in the weighing scale whilie the power supply is off. See what the weight of the magnets is. switch the power on and see whether there is any change in the weight. try repeating this a few times using different currents (measured on the ammeter). 100grams=approx 1Newton of force
