Raspberry Pi 3: Enabling VNC
Quick guide to enabling VNC allows for remote debugging / a way of working on a raspberry pi without actually sitting next to it. After having connected to a wifi network we can begin enabling the VNC connections.
Raspberry Pi Email on boot debugging
Often when moving a raspberry pi project around it’s IP changes. whether it is on your home network or a new one, it becomes a task to figure out it’s IP.
Raspberry Pi: camera video stream to host
While playing with the raspberry pi camera I found it hard to know if the camera was working or trying to tweak settings. I was using raspivid -f to preview the video. This was limited with being open for 5 seconds ( can be adjusted using the -t flag and passing it seconds in milliseconds ). The solution was to open a streaming video from the raspberry pi and view it on my host ( mac ).
Raspberry Pi – Sharing file between PI and Mac
Mounting the raspberry pi home directory to avoid the push / pull game with git can become painful. It’s relatively straight forward to get shared folders using the appletalk protocol
Raspberry Pi 3: Rotate screen on boot
When working on projects for the raspberry pi, it’s sometimes needed to have the screen be rotated, we need to go and modify the boot config of the raspberry pi.
Raspberry PI RC522 Setup
Connecting to Raspberry pi 2, 3 and zero to a RFID sensor, This summarizes my experiences using the tutorial found on Sunfounder.
Virtualizing the Raspberry Pi for local development
Starting new projects can be difficult, especially when the need arises to develop / debug. It is key to have a development environment that closely matches the same hardware / software production environment it will be run on in production.
Raspberry Pi: Multiple wpa_supplicant networks
Imagine building a raspberry pi project at home that is dependent on wifi. Everything is working perfectly until you move that project somewhere outside your home network. You have to go find a monitor and keyboard to set it up on the new wifi. This process is difficult, time consuming, and stressful. I have had the pleasure to endure this multiple times throughout my projects. Especially when there is pressure to have it done for a public event. I was curious if there was a way to get the networks to be plug and play, where there would not be an issue when moving it from one place to another. Doing a bit of research I have found that you can setup multiple wireless networks on the raspberry pi.
