A new series on AddOhms, Electronics basics, starting with: Voltage, Current, and Power Explained.

Starting with this new AddOhms TutorialCast series, we are taking a look at Electronics Basics.  The first topic is on the differences between Voltage, Current, and Power. The twist on this explanation is that we are not using the usual “electricity is like water” analogy engineers seem to love.  Instead, we just use plain language to explain the difference between these concepts.

Purdue Boilermakers are MAKERS!

George at nbitwonder caught this outside the Armstrong Hall of Engineering Purdue while walking to class.  The signs read:

I think work should be about making things work.  Better.  Faster.  Smaller.  Smarter.  So I build bridges between what’s known and what’s not.  I tinker.  I toil.  I write poetically in an abundance of languages (including code).  I hack.  I dissect.  I have an insatiable desire to un-complicate the complicated.  I am easily inspired.  I believe that just because it hasn’t been thought of doesn’t mean it won’t be.  Potential is my thrill ride.  Imagination is my most-used tool.  I am a maker, and I am what moves the world forward.

Always good to see I picked the right school for my EE degree!

EDN: ICs could run on heat waste

Joseph Heremans and Roberto Meyrs at the Ohio State University have been studying materials that could be used to turn heat from ICs into electricity. The research is focused on thermo-electricity and spintronics. In theory, this could mean mutual benefits to heavy processing: more effective heat removal from processors while generating the electricity they need to operate. Read more
