i have found this diagram :::scroll down a bit for the diagram::: http://sci-toys.com/scitoys/scitoys/computers/solderless/amplifier.html could the Darlington transistor be replaced with a "normal" transistor and also using resistors of lower value? Also, is the input wire connected where it...

with the amp in the link, how would the input be connected to a 3.5mm auxiliary jack ?

Hi, I have a single 2 watt, 8 ohm speaker from an old radio that i wired directly to a headphone audio jack and tried it in my phone. as you can probably guess, my phones speakers are much louder. How could i make a basic transistor amplifier that could give decent volume from the speaker...

this is a question i have to do over the holidays and have no clue of how to do it. i cannot access our school email in which i have the worked solutions to all the questions. A ball is tied to a string and whirled in a horizontal circle radius of 2.0m. The string makes an angle of 10...

thanks, In a reactor that uses U 235 as the fuel, from my understanding, neutrons need to be slowed down so they can be absorbed by the U 235. what was the original source of the fast neutrons/how were they produced. are fast neutron reactor also known as breeder reactor or is that different.

just curious, is Americium 241 a fissionable isotope. if it is, is it possible for it to undergo a controlled chain reaction from bombardment of neutrons.

thanks for the explanation. it would be great if the 2VDC could be turned into a useful 240VAC.

thanks Dave, so what could actually function at 240vac at a really low current?

i have just recently discovered peltier devices which make electricity from the Seebeck effect. one video on you tube showing peltier device producing about 2 volts from a flame. i would like to know how to convert this 2 volts DC (if it is actually dc) into 2 volts AC then put it through a step...
