My Foginator 2000

    It all works nicely, as of this afternoon.  I simplified the audio because I did not get my Raspberry Pi audio cable ready.  With as many Raspberry Pi B+ and newer that have been sold, I wonder why someone does not build audio cables.  Ideally, it would be a short cable with the weird Raspberry Pi trrs connector on one end and a female 3.5 stereo audio jack on the other end.  Then, you could plug cheap computer speakers in.  I mount Raspberry Pis on the ba ...
  I added startup for all the main pieces.  On both Pis, this meant adding a line to near the bottom of /etc/rc.local. The line goes just above the exit line you see at the bottom.  Here is what I added:   sh /root/start_watching.sh &   I started the shell script running in the background.  The shell script waits 30 seconds, then mounts the samba share of the other Pi.  I start this script in the background so the main console stays ready for logins, if ...
  As I mentioned last time, I added a Raspberry Pi B+ to the project, basically to take advantage of its GPIO pins.  Today, I was going to start interfacing the Arduino , which is driving the Neopixel stick.  I had read that there was a nice library for letting ArmV6 Raspberry Pis Raspberry Pis drive NeoPixels.  So, I movel the NeoPixel stick over to the secondary Raspberry Pi in thes project, which is a Raspberry Pi B+.  I tried out the library and it works quite well s ...
I got a box of nice parts to build my copy of the Foginator 2000   My biggest  confusion was what to do about the other parts I would need.  I did not know if they were arriving seperately or whether I needed to order them.  As time was growing short, I decided to proceed with experimenting and plan to visit Tanners Electronics in Carrollton to get more parts locally.  Fortunately, Tanners is a great local resource if you are near Dallas, Texas.     I start ...
  This is my second blog entry about this project.  I must have saved the first one to the wrong area on Element14, and I'll work on moving it after I finish this entry.  As I mentioned in part 1, I could not get the special pin extender in time to mount the PIR detector on the Raspberry Pi with the Sense Hat.  So, I elected to add another Raspberry Pi to the project and connect all devices other than the Sense Hat to it.  It is a Raspnerry Pi B+, which I had as a spare. ...
