Well, when I last time learned interrupts, I was actually a teen and I read a book, not web pages. I'll surely learn it again on paper!

No plans for it - except to look at FPGA programming. (note the Sparkfun logo: Expert programming skills required ;) ) Theory is fine, but what does it feel like  :smiley-yell: ? ;) But with it the Blinky-LED programs can run incredibly faster. :D

Interesting, I got one of these recently:

I have a more substantial FPGA development board but its hard to integrate into a project.  CPLDs are easy to integrate, but they only take small designs.  This is easy to design in and takes the same sort of VHDL or Verilog.  Yours has a more recent chip, but its probably not more powerful for most purposes and is more expensive.  I like these relatively cheap solutions.  FPGA/CPLDs are fun.  If what you are trying to do is just logic, they are so much faster than microcontrollers.
I will never ask you to do anything that I wouldn't do myself.

How about Christmas, for those who celebrate?  Anything interesting?

I made out like a bandit..  BeagleBone Black from one of my brothers (who doesn't "do this sort of thing", so it was quite a surprise!), another older sibling gave me a nifty solar panel with Li-Ion pack for... whatever I want to do with it.  (I immediately connected it to the BBB.  His wife asks, "don't you use anything as intended?" referring to the cell-phone charging commentary on the box.  "Following directions suggests a lack of imagination," I replied.  XD)

But my better half really took the cake.  Out of nowhere, she risked her life and limbs to enter the spare room I sometimes refer to as my evil genius laboratory, dug through piles of stuff to find my tools, then looked online through maker guides to see what I was missing.  The result: a set of Klein wire strippers (one for 30! to 20 AWG, the other for 18 and up), a big pair of auto-adjusting strippers -- which is a lot of strippers, but seriously, I had been using those cheap crimper/stripper/bolt cutter things from the box stores, or a pair of scissors, or my teeth -- also, a set of Wiha precision screwdrivers and SMD tweezers, a 90-deg angle drill adapter (I had been complaining about tight corners on a subwoofer box I was building), and a Porter Cable oscillating multi-tool.  I was seriously impressed!  I had tool envy for my own tools.

I'll have to remember that when next time the wife asks why I won't stop to ask for directions.  ;)

Lady Nickity bought you, not one, but several strippers for X-mas?

I'm envious!

A new graphics card for the computer. So what to do with the old one (which had started to reset at random times - and couldn't cope with the requirements of SimCity's newest extensions)? Probably can reuse the fan - but with highperformance electronics parts are too specialised for much reuse.

After a really very long time  of deliberation, I finally decided to buy a powerful regulated power supply (thus powerful for my modest needs).

Very nice. Having an adjustable current limit on a bench PS can be a aid in troubleshooting equipment and new circuitry. Helps keep the magic smoke inside the components.  ;)

The cover says 18V and the LCD says 19.0V  :smiley-eek-blue:

Well the LCD says 19.0 vdc, that attached DMM seems to read 19.05 vdc. The panel says it's a 0 to 18vdc voltage range. Sounds all good to me. Keep in mind that there is no current being drawn from the supply at that time.

But it's regulated!   :|  There shouldn't be an unloaded voltage.

That's nice though -- I've been thinking more and more about getting building a programmable bench supply.  In the meantime, I usually put in the smallest fuse that should do the job, plug something in to a power strip, and hide behind the cat as I power it up.

I like that because of the fixed 5 and 12, over and above whatever you choose on the main output.
