UrbanRest Guardian Project Introduction Greetings! I'm Enrique, a Spanish software developer working in the credit card payment industry. I've been having trouble sleeping recently. Noise in my neighborhood has gotten crazy. It's a constant mix of traffic…

Project goals The goal of CycleSafe project is to improve safety of cyclists on the road. The secondary goal is to make it affordable for a wider community. Project Overview The project will use RPi 4, a camera, and machine learning algorithms to…

Intro This blog in the Experimenting With Extreme Environments design challenge is to satisfy the requirement for a deep-dive into the kit components. The deep-dive blog is worth up to 20 points so I will endeavor to make at least 20 comments or points…

Intro During this year's Experimenting with Extreme Environments design challenge I have decided to continue my work of identifying edge cases of environmental origin when deploying electronic systems outdoors. And - as of outdoors - I am not even thinking…

Intro This blog demonstrates the PicoPorch system in operation. All electrical and mechanical subsystems are now built and functioning although one of the stands still needs a few pieces and one of the cameras has not been definitively selected. Despite…

Design Changes When I tried to connect the RPi Compute Module 4 I/O board with RPi Camera v2 I realized that they were not compatible. So, As I have a USB camera I've decided to reuse it instead of purchasing an additional camera. Here is the new design…

Ending the series with remote monitoring With this fifth blog, I conclude my series of optional blogs for the Experimenting with Extreme Environments design challenge sponsored by Hammond Manufacturing . Throughout this nearly bi-weekly series, I have…

Intro Another quick update in the PicoPorch saga. This time I have been wiring up the power box and printing off enough bracketry to make the system functional so I can finally start capturing some video. It is now almost to the deployable stage. …

Intro Let's start with the riddle: what is it? A box with transparent top, placed at the backyard in the sunny place? This? or maybe this? Let's check what direct Sun radiation does to our (set of) waterproof enclosure(s). Black box or white…

Intro Another element from our design kit is an LCD display. It is 4x20 unit made by Midas Displays and driven by RW1063 chipset, which seems to be designed with Hitachi HD44780 compatibility in mind, including pin-to-pin compatibility (as can be seen…

Intro During my last year's project I have deployed array of sensors to monitor environmental parameters inside three enclosures: Hammond 1554VA2GYCL that was then tested (along with the array of waterproof - mainly RF - connectors) and which was…

Why do I need to test the enclosure? CycleSafe will be used in the outdoor environment. It will be subject for all kinds of environmental conditions, including snow, and vibration. The role of the enclosure is to host and protect sensitive electronic…

Introduction We're now halfway through the Experimenting with Extreme Environments challenge , sponsored by Hammond Manufacturing and Element14. This marks my third blog, detailing the progress of my UrbanRest Guardian project, aimed at monitoring and…

The purpose of this blog is to take a deep dive into the IP68 Waterproof Enclosure, supplied by Hammond. As part of a Design Challenge titled Experimenting with Extreme Environments , sponsored by Hammond Manufacturing , I submitted this extra credit…

The goal of this blog to describe my design of my initial idea, for an element14 Design Challenge. It will describe the functionality and the technical aspects of my idea. My idea is to conduct a number of tests to determine the Ingress Properties Ratings…

Intro This update in the experimenting with extreme environments design challenge focusses on the motor mechanism which allows the camera in a Hammond enclosure to pan across the yard. The Motor System Video …

Intro My project in "Experimenting with Extreme Environments" is planned as an continuation of work I have done in "Experimenting with Waterproof Connectors", which - while giving some interesting results, have left questions unanswered and some topics…

Wildlife Monitor Introduction The purpose of this design challenge is to test the performance of a Hammond IP68 enclosure housing an electronic project in an extreme or harsh environment - "Experimenting with Extreme Environments" . The inspiration…

This is my last extra credit blog. Solar Module Assembly I've had all of the solar panel components hooked up and running with the exception of operating with the actual load of the CM4 and sensor assemblies. The two final integration steps are to…

I'm back with the second blog for the Experimenting with Extreme Environments Design Challenge . In my first post, titled " UrbanRest Guardian - Project Introduction ," I introduced my project idea: the UrbanRest Guardian, which focuses on monitor and…

Enclosure Modifications Modifications need to be made in the form of additions to the interior and exterior of the enlosure to mount parts into the enclosure and attach the enclosure to its mounting pole. Baseplate to mount the CM4 IO and RS-232…

My challenge hardware kit arrived via UPS on April 2. Thanks E14 and Hammond for sponsoring the challenge. This blog will cover the unboxing of the kit, a detailed description of the components and how I plan to use them. I'll also cover other additional…

Introduction This is my initial blog for the Experimenting with Extreme Environments challenge. For Christmas last year I received a 115W bifacial solar panel. I had mentioned to my family that I wanted to build a portable DC solar module that could…
