Solar Powered Internet Connected Lawn Sprinkler Project

I’ve been looking for an excuse to do a little project with Adafruit’s Feather HUZZAH board and MicroPython. As an engineer who graduated some years ago, having a Wi-Fi enabled micro-controller which runs (Micro) Python 3 and costs less than $20, is really amazing. My initial plan was to use this automatic lawn sprinkler to be a rodent deterrent to keep rabbits and squirrels out of my lawn, but I have also used it to keep flower beds and newly planted trees hydrated....

Camera Time-lapse Controller with Python and Raspberry Pi

In my quest to travel with the least posible amount of equipment, I decided to leave the intervalometer at home and use the Raspberry Pi as a time-lapse controller for the Sony A7 II. Since time-lapses take a long time to shoot for obvious reasons, I’ll be using the Sense HAT on the Raspberry Pi as a progress bar to give the user a general indication of how many shots are left....

Scripting on Raspberry Pi from iOS and Mac OS

In the last weeks I’ve spent quite sometime tweaking a Raspberry Pi 3 to be used as a travel photo backup device. It has now become a travel access point, media sharing device and a time-lapse controller for my Sony A7II. It’s really a wonderful and versatile little device. One thing that all these projects have in common is the Python programming language. In the last years, I’ve become a huge fan of it and have learned to use it to automate several tasks both at home and at work....

How to Backup Photos While Traveling With an iPad and a Raspberry Pi - Part III

Background Information This is the third part of a series of posts on backing up photos while traveling using a Raspberry Pi (RPi) and iOS devices (here are both Part I and Part II). Although each part ends with a perfectly working solution, subsequent parts built on the previous one, aiming at having a streamlined and easy-to-use process. The general process continues to be the same: This time, I had 3 clear objectives in mind:...

How to Backup Photos While Traveling With an iPad and a Raspberry Pi - Part II

Background Information This is Part II of a series of posts on backing up photos while traveling using a Raspberry Pi and an iPad Pro. In Part I, we covered how to set up both the Raspberry Pi and the iPad to be able to establish a secure (i.e. SSH) connection between them and manually run a script to copy photos from an SD card to a thumb drive (both connected to the Raspberry Pi’s USB ports)....
