Building a DSLR Camera Wireless Controller

I’ve been experimenting with time-lapse shots for a while now. Unfortunately, time-lapse shooting options on most DSLR and mirrorless cameras are somewhat limited. At the time of this writing, Sony doesn’t even include the feature on their high end cameras by default (you need to buy an “App” and download it to the camera). Some time ago, I posted the setup I had been using for shooting time-lapses using a Raspberry Pi, a portable battery and a USB cable....

Ambient Conditions Monitor using a Raspberry Pi Zero W and Sense HAT

I’ve been looking for an excuse to use most of the capabilities of the Sense HAT on a project. I’ve used it before as an interactive/visual interface to run scripts on a Raspberry Pi 3, but that project was really underutilizing the board. The Sense HAT is part of the AstroPi project (the project that allowed UK schools to run experiments in space). It bundles an 8x8 color LED matrix, a mini joystick and a ton of sensors (barometric pressure, humidity, temperature, accelerometer, 3D Gyroscope and magnetometer)....

Publishing from Bear Notes App to Pelican

I’ve used Ulysses writing environment for months and I’ve come to really like the experience. It’s stable and nicely designed, iCloud implementation is great and it even allows adding external folders to work with (although integration with their database is not perfect). Ulysses may represent the perfect environment for most writers: pure text, pseudo markdown, clean interface and a distraction-free layout. However, I think I feel more comfortable writing on an App that closely represents what the final product is going to look like....

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....
