Do You Have An Electronics Niche?

Although we all consider ourselves to be electronics hobbyists, most of us tend to have a specific area or niche where we are most prolific. For some it's radio, for others computers, music and building amplifiers, or even just fixing broken stuff. What is your favorite area of interest that most of your hobbyist activity revolves around? Is it still the same thing that originally sparked your interest or has it evolved over time? 
 

That's It. Enjoy!

Just as other sculptors are blessed with the vision to see their works of art hidden in wood and marble, I have developed the ability to see antennas hidden in metal. After working with antennas for a while, I believe most everyone can probably develop an eye for dimensions that are quarter-wave multiples of their favorite frequencies.    
   
How do I test the condition of the contacts of a 24-volt, 30-amp, sealed relay?       
Choosing A Heatsink
CHOOSING A HEATSINK

Let's face it - if this article was titled, "Thermal Analysis," you might put off reading it! But choosing a heatsink? Everybody understands what that's all about, right? To make that choice, you have to do a little thermal analysis (gotcha!), but if you can do Ohm's Law, you already know how!

Okay, you've wired up the latest whiz-bang sensor to your processor-controlled project. The sensor has been connected to the 12-bit A/D and now the moment of truth. You apply power and look at the data ... Hmmmm, the numbers don't look quite right.    
      
I have heard that there is a way to be able to read higher frequencies on an oscilloscope than those for which the oscilloscope was built. I was wondering what circuit or devices are needed to accomplish this task.

I've been tearing down Seiko solar quartz watches in search of small efficient engines to power miniature robots... 

I have a bunch of 2 lb rolls of leaded solder that I no longer plan to use, given the availability of lead-free solder...

No matter what I think of, I cannot come up with any logic circuit that would ...

I have three mini monitors but no power supplies, and would like to know what power supply to use. I don't want to burn any of them out using the trial and error method.
