Hi Dave!

 BM> My What I'm Going to Do Today is a mental list (um, in my head, though a
 BM> little crazy!) and depends somewhat on the weather: not going to be
 BM> doing yard work in the rain.
 DS> Yep thats how I tend to get shifted from one project to another.
 DS> Weather was too bad to work on one so I started another. Needed
 DS> to do something before I could continue that, so I moved to
 DS> another. Just keep going in an endless circle sometimes! :) My
 DS> Vivance doesn't seem to be keepign up with me! :)

Your But Firsts seem to be more aggressive in distracting you than mine!


 BM> Do have scratch paper/note cards and pens
 BM> in various palces in the house, not for writing down what to do but
 BM> sometimes at 'odd' times like brushing my teeth or drifting off to sleep
 BM> I'll think of a potential solution on a project.  So have a little stash
 BM> of paper in the bathroom cabinet and in the bedside table.
 DS> I've tried that. Sad thing is I can't read my own handwriting!
 DS> Pharmacist told me my writing was worse than any doctors she's
 DS> ever read! :) I do like spreadsheets so I try to keep a
 DS> spreadsheet of stuff to do in google docs. I just tend to get
 DS> sidetracked with trying to tweak the sheet formulas and such
 DS> then! :)
 
My writing got ruined from high-speed note-taking in college; in 
hindsight Gregg Shorthand would have been helpful but I don't know of 
any tract in the sciences where shorthand is an option.  That seems to 
be an exclusive of the 'secretarial' tract.  Actually "Intro to Home Ec"
would be good for college students: how to sew a button, how to clean 
the dorm room and do laundry (why is everything pink?!)....



 BM> I finally found one, plugged it in, and -- nothing.  Did a help post to
 BM> the MythTV Forum (because where is going to be used and they have used
 BM> remote controls instead of keyboards); got an impressive reply
 BM> (detailed) which helped but I ran into a snag near the beginning; should
 BM> get a response back this morning.
 DS> Thats awesome I hope ou are able to get that to work! I was
 DS> looking at the MagiQuest wands a bit. It looks like they operate
 DS> at 36 or 38 KHz. Found some stuff on openschemes.com that looks
 DS> promising. Seem to be other folks who have tinkered around with
 DS> it in the past (I'm always a day late to the party). I just need
 DS> to find a good IR receiver that works at those frequencies and
 DS> with the Pi.

Most do.  Check www.lirc.org  -- scroll down for the link to the
database ("Supported Remote Controls" header).

I used a receiver from a Hauppauge tuner -- can't find the specific
right now but is one of the two or three commonly used IR detectors in
a pretty plastic cover and connecting cable.  The problem I had was the
extraction/build/whatever didn't automatically create several files so
while I had the first step of detection and decoding and the last step
of doing something with it Step 2 of linking the two was missing.  (I
used to watch SouthPark and the episode about "Phase 1 - make
underpants, Phase 3 - Profit! -- What's 'Phase 2?" 'We dunno'" comes to
mind!)

BTW, it appears connecting the IR detector to an RPi 3 and to an RPi4
are different.  The GPIO pins are the same, maybe the firmware changed??
I can give links if you want them.

....Your comment I just need to find a good IR receiver to work with
MagiQuest wand and the RPi',  I'm going to say probably not too much of
a problem; maybe check out this 1 minute video  
https://www.youtube.com/watch?v=BZec247UpLM  -- I didn't view but the 
text onthe page indicates it is working with an Arduino.
