If you want to go a little more professional than the Hobby Mags...

EDN... www.edn-europe.com (there's also an Asian version, Australian version, your part of the world version)...

ESE... Embedded Systems Engineering... www.esemagazine.com

Both of the above (there are many others) are FREE... as long as you qualify for the readership... but you don't need to subscribe for the printed copy to look at articles on the websites.

If you are a basic Hobbyist or Student, those mags may be a little over your head (quite apart from the fact you wouldn't qualify for FREE subscription - I base that comment on the questions posted on this forum) as they assume the reader understands what they're reading...

For example... if you can't follow this... (Generating Sine Waves - topical for another recent thread on this forum)...

http://www.edn.com/article/CA6321527...dustryid=44217

then it's not the kind of mag for you...
