I have a 5v, .2a (1w) pulse system with a 24 Hz/.7 duty cycle that originates from a dc inverter I found that meets those specifications. I know very little about transformers, I mainly know DC. Can you have an AC system that alternates between 0 and 5v instead of -5 and 5v (or whatever)? I...

Really, physics is applied math – you can't get that far in physics without knowing quite a bit of math, especially quantum physics (quantum means that something is quantitative which means that it can be derived into something numerical… hence, math). However, I would try to focus on learning...

I am looking to find a 5v to ≈70v dc-dc converter in the 1w range or the equivalent transformer + diodes. This is for a bio stimulation device and I need a high voltage and low amperage. However, not having spent years researching and buying electrical components, I'm a little uncertain where...

I am working on a robotics idea I had, and I would like to keep the cost within reason I haven’t found anything that is commonly used (and therefore, I am assuming this implies there is nothing commonly available). I have found a recently published paper in Science (February) on using twisted...

I am looking for a commonly available, non toxic material (i.e. on the market today for a relatively low price) that exhibits reasonable expansion and contraction in size when electricity is applied. This could be a gas, liquid, easily workable solid but ideally it would be a fabric or flexible...

I have an idea for a research project in neurobiology but I have only a limited background in these fields (I currently work in web development). Is there any way to gain the necessary skills and have access to the right equipment to carry out the experiments I want to do without going back to...

Just using the key words insolation versus altitude has given a few more relevant results (goes to show that having the right search terms in research is key), but I have not found any hard numbers for solar wattage at the top of the troposphere (I mistakenly used thermosphere in my first post)...

At what altitude does a solar panel see a noticeable increase in wattage/cubic meter if it is lifted into the air? I understand the maximum is a bit over 1 kilowatt/meter2 at sea level (not actually converted to usable energy, this is much less and depends on the technology) but that this...
