Temperature, Humidity and PM2.5 Air Quality Sensor with Arduino

I built a really cool little temperature and air quality sensor that reports data to particle.io events and from there into influxdb cloud. With Free Dashboards!! Yes I mean free as free can get. Particle.io, free (to 100 devices). InfluxDB cloud, free (to (x) amount of stats). We’re not talking about a lot of stats here, but after many hours of research for a free dashboard solution this was the absolute best!

Building a Mercedes sprinter motion detecting van alarm with remote pager

I wanted to protect my home on wheels with a nice alarm system that could page my cell phone when an intruder was detected. After much research and calling various car alarm installers in my area I came to the conclusion that it wasn’t worth the expense, the risk to my van’s wiring, and voided warranty. The commodity car alarm systems like Viper seem stuck in the dark ages and they don’t have a wide range of detection methods.

My OpenPlotter Screen, Custom Pi-Hat, and Hardware

27 Oct, 2019 - 2 minutes
Screen and Keyboard I bought two of these screens because I love the low power consumption and ability to run off my 12v DC in the boat without turning on an inverter. I didn’t know which size I’d like the best and I ended up using the 13.3" for my navigation system and the 15.6" for onboard entertainment. GeChic 1305H 13.3" GeChic 1503H 15.6" Custom RPi HAT RPi HAT prototype board The prototyping style RPi HAT boards are what I used to create a solid connection to the compass, accelerometer, piezo and Real Time Clock.

Installing the latest OpenPlotter on Raspberry RPi4(RPi3)

Being an Openplotter fanatic and using it on my boat as my primary source of navigation I decided to create a new sd card image build based on the latest Raspbian Buster so that I could have full control of what’s installed and create an optimized and up to date version of Openplotter for my navigation system. I also recently aquired a RPi4 so I will be testing on both RPi4 and RPi3.
