I build plastic 1/87th scale models in polystyrene and would like to switch over to metal. Since the pieces are so small I really can't weld them effectively. What metals can I solder using a 150 watt soldering gun or I do have a brazing torch though I haven't had luck brazing brass tubes together. Just need to know what light metals I can bond together with soldering/brazing that I can purchase at a hobby craft store and if there are any tips since I've only soldered wires together and can't get anything else to bond. Thanks!

I've just bought a Swatch, and on the back it says Patented water-resistant...... four(4) Jewels, I also went on e-bay to look at watches and found some realy old (50's/60's) watches with 17 and 23 jewels in them, I guessing the jewels aren't diamonds or emeralds etc so what are they? and why are they in the watch?

I am researching this for a paper and I wonder what the public opinion is and facts about why it is that Germans seem to be exceptional at engineering.

Please tell me how to wire the bulbs together, the voltage ratings of the bulbs and the values of any componants (resistors?) needed between each bulb to allow them to light in sequence as the DC voltage increases from 1 to 12 volts. I would be extremely appreciative of this information on a home project of my own. Thank you in advance for your considerations. Monty

what conversion does the electrical energy forcing its way through a (light)bulb go through? is the energy used up?



if you had 2 motors to wire and you wanted them to run at full power and not burn up, how would you wire them?

Am I missing anything?
Ok for my science fair project I already have:
Procedure
Materials
Purpose
Results
Analysis
Hypothesis
Experimental Error
Am I missing anything?
I also have 2 pictures and 2 graphs!!!
So... help me am I missing anything? And will 2 pics. and 2 graphs be enough?

i performed a formula to see how much volts and amps a capacitor discharges in each millisecond and the question is if i did it right the capacitor had 150uf and the battery that charged it had 1.5v and 5.0a and i even made a chart of the results so did i do it right?
(note: the letters along the bottom are the milliseconds and the ones along the left side are the measurements)

both are based on these formulas
V=v(e^t/T)
the instantanious voltage is equal to the initial voltage times exponent to the power of time over tau

I=i(e^t/T)
the instantanious current is equal to the initial current times exponent to the power of time over tau

heres a link to the chart
