INTRO We're currently experiencing a wild fire smoke apocalypse in the entire western USA. You can see the blanket of smoke that's currently surrounding my home in the cover photo. I've been checking the air quality every day on WA Smoke. Because the air here is still unhealthy, we've had to close all our doors and windows and remain indoors, and I was curious to see how this has affected my indoor air quality. Thankfully, I just happened to have Avnet's ZMOD4410 Indoor Air quality Pi Hat sitti ...
Hello, i'm here to show you my CRAY Y-MP reproduction i have built over the files of RABBIT ENGINEERING found on thingiverse for Raspberry pi Zero.I have printed the files in 4 days, it tooks so long "sleeping apart". Printed in white pla and painted with the right black and orange acrilics colors. I have installed in it a Raspberry pi Zero W that does his work also over internet installing lynx browser for linux.The most difficult part was print the 16 duplicated parts with my printer without ...

IntroductionThis blog builds on what Kevin Keryk did with he Monarch Go Starter Kit witht he Ultra96V2. We are going to establish a headless setup, setup a Point to Point Protocol with the Monarch Go Modem, and finally setup a IoTConnect demo over the estabished LTE Connection.   VersionDate Version Revision 17 August 20 01 Initial Release   Required Equipment Monarch Go Pi Hat Raspberry Pi 4 B 16GB MicroSD Card USB Type C Power Supply   Raspberry Pi 4 B Headless Setup and ...
Introduction The Monarch Go Pi HAT is a cellular connectivity add-on card for SBC boards that have a Raspberry Pi HAT-compatible connector. Fitted with Sequans Monarch Go (or Monarch Go GPS) LTE Cat-M1 modem, this HAT board also facilitates expansion via Click boards using a compact onboard Click Shuttle connector. Noteworthy is that an integrated onboard USB-UART bridge interface allows this LTE HAT to also be used with other platforms.   Version Date Version Revision 06 August 20 01 Ini ...
The Raspberry Pi 4 can easily be configured as a 2.4 GHz or 5GHz routed wireless access point or as a bridged wireless access point.   My intention was to create a wireless network outside of the home. The configuration only took a few moments thanks to resources provided by @raspberrypi.     The results are excellent. Speed and signal strength are more than expected. Good enough for flawless hd video streaming and quick downloads.     Cheers to Raspberry Pi!! &# ...
I bought this cute case for the Raspberry Pi. It's made by Italian company Italtronic, in the UK avalable from CPC. They have cases for different Pis. Mine is for the B+.     Assembly  It's easy. There's no Ikea-style manual though, so you may get it wrong the first time. The only tool required is a screwdriver. The Pi is locked in place with 2 screws (included). Some attention is needed: wait with assembling the black rail mount spring until the box is assembled and close ...
As you know, Raspberry Pi doesn't have native ADC, DAC, CAN Bus controller and other low-level peripherals found in most modern microcontrollers(MCU), such as STM32, Arduino Due, Teensy dev board. Normally this issue is ensured through external modules added to Raspberry Pi board. These are I2C and SPI modules like MCP3008(ADC chip), MCP2515(CAN bus), MCP4725(DAC) and other MCPXXX-like boards. But if you use an MCU for these purposes you have multiple peripherals at the same time. However, th ...

********************ISSUE RESOLVED. Credit to shabaz for identifying that a networking device was the issue.  ***********************   I would like the assistance of members that have PoE experience in reviewing my findings to help troubleshoot Ethernet failure under PoE.   I powered up the Pi4B & PoE Hat using a PoE power supply and managed to ssh over the wired Ethernet connection. Satisfied it worked, I command lined "sudo shutdown -h now" so I could teach go teach a cla ...
Frustration, doesn't begin to describe the emotions I'm experiencing. I just received confirmation from Newark Canada that an in stock item that was ordered on the 3 April, has been shipped. I have been waiting for a PoE power supply required to further the The Road to Raspberry Pi4B/ PoE Hat RoadTest Review Raspberry Pi4B (4GB) plus POE Hat .   Let's list the anomalies that may have contributed to my frustration: COVID-19 pandemic social distancing protocol implemented in my country Apr ...
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 ...
