(UK) A-Level Extended Project

[jbirtles]

Hi guys, I have been watching the show for a while but this is my first post.

I'm doing an EPQ at a-level where I get to choose what project I would like to do be it an essay, dance, or artifact.

My project title is "Develop and Produce an educational kit for building a hybrid between a multimeter and a calculator". What I am really here for is  help in compiling a list of sources of information. I'm not asking anyone by any means to do my project for me or do any of the research for me, I am however asking If any one knows of any good sources for learning about measuring voltages.

I know a little about ADCs however sources on these would be great.

I have found a bunch of resources myself however due to the nature of hobbyist electronics, these are mostly blog posts and wikis. This means in order to make these sources more credible, I need to have someone almost vet them for me, or at least recommend it as a resource.

Thank you for all and any help with this, you can follow my project if you so desire on my blog - http://jamesepq.weebly.com/.

P.S. You can ignore some of the bullshit I have to write to get a decent grade on my blog.

Perhaps not exactly what you're after, but have a read anyway I'm sure there'll be something of interest.

You might check out the other App notes listed at the bottom of the second link also.

HTH Steve.

auto-ranging for a multimeter input is also fun, the ones that use an analog switch ic to change the divider with a clamping diode is one of my favorite approaches,

equally if your combining the functions, think about being able to use the measured value in basic calcs, i remeber dave doing a video about one of these products which did exactly that,

Bit outdated but might still be useful - Art of Electronics (2nd edition) has a section on A/D converters around page 621. There will probably be a copy at your school.

Thanks for the links/book suggestion. I have taken a look in my college library and they indeed did have The Art of Electronics. I also got out Electronics Explained (M.W. Brimicombe), and Analogue Electronics (J.C. Morris).

If there are any other books anyone could recommend me that would be great. I am doing electronics in college and have been playing around with electronics for a few years but I haven't really got into anything more complicated than following an arduino tutorial until recently so any book from beginner to advanced, I'll read it eventually.

Thanks again.
