The Raspberry Pi 4 is a great upgrade from the previous Rpi 3. It even performs (surprisingly well) object and facial recognition with the Tensorflow Lite framework (1-2.5 fps) or OpenCV library (1.5 - 8 fps) and PiCamera.   During my first applications of Tensorflow Lite and OpenCV for facial recognition with my Raspberry 4 I realized that long term usage would be quite critical due to temperature issues of the CPU. Without any cooling device (passive/active): Under normal working load t ...
A part order arrived today that provided some additional resources to proceed with the testing.   I ordered PoE power supply on April 3 and the Pi4B power supply on April 15, from Newark Canada, guess which one arrived first? The Pi4B power supplies!   Both items where listed as in stock. The PoE power supply is listed as "In Processing" for order status. The man responsible for managing RoadTests Mr.rscasny  has offered to look into the anomaly. Nothing like a man in high place ...
I had a Squirrel moment, after completing the testing in The Road to Raspberry Pi4B/ PoE Hat RoadTest Review (comparison Pi3B+) . A squirrel moment going off and doing something, that takes you away from your current focus.  I was focusing on developing a load test for PoE and then thought I wonder how the Pi performs with just heat sinks and no fan.   The PoE Hat contains a fan to cool it's switching power supply that converts the incoming 48VDC to the supply voltage needed by the Pi ...
While in a holding pattern, waiting for power supply deliveries for both the PoE and Pi4B, I started some parallel work that was proposed in the RoadTest application. Since the specification indicated the PoE Hat was compatible with the Pi3B+, I figure I could start laying out a RoadTest Review framework using the Pi3B+. When the Pi4B is ready I will run the same tests.   Some observation were discovered while Installing the PoEHat on the Pi3B+. Raised heat sinks on a Pi may conflict for ...
My desire would be to open this post with an Son of a who cut your hair last expletive. My tendency to sprinkle pearls of vulgarity in my posts has given cause for the forum moderator to apply sanctions. I'll settle for the graphic to hopefully pass the review..   The Pi4B and PoE Hat arrived today. That should be reason for joy right, not profanity. Unfortunately, the Pi didn't come complete with a power supply. All my Pi hardware is pre-Pi4. I don't have a Type C power supply required ...
I'm building a SCPI electronics lab instrument for Linux. In this post I'm creating a service wrapper and install the Linux service. It will start at Pi startup, and can be stopped / started as you'd expect from a service.   Prerequisites  You should have built the two binaries for this project, as documented in post 4a and 4b. If you didn't, the binaries are available as archive attached to post 4b. linux_scpi_socket linux_piface_digital_service_cpp These binaries should be ...
I am no stranger to working from home. Having had my first experience of the internet in the late 90's with a dial-up modem, and then in the early 00's with the advent of cable modems in the United Kingdom, it was early on that I jumped into Voice over Internet Protocol (VOIP) and doing internet calls, while gaming on ID Software's Quake 3: Arena and Bioware's Neverwinter Nights using Ventrilo, Skype and Roger Wilco. It is almost second nature to me now, fortunately, that when asked to use softw ...
While I was participating as a team member for element14 to help folding@home analyze coronavirus https://www.element14.com/community/thread/75254/l/set-your-processors-to-analyse-for-the-covid-19-virus-with-foldinghome I wanted to use my rPi4 to help with the effort.  Unfortunately, folding@home does not support the ARM processor, mentioned by cstanton and ninjatrent. They support Windows, Linux, and Macintosh, but on the x86 CPU only.  Doing all that works well, and I have my older ...
