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.
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 ).
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
Connecting to Raspberry pi 2, 3 and zero to a RFID sensor, This summarizes my experiences using the tutorial found on Sunfounder.
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.
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.
People often ask me what is possible with the power of the raspberry pi. I’m have a tendency to buy numerous microcontrollers / cheap standalone controllers, just to see how they work and if they could prove more useful to me than the raspberry pi. The release of the Pi Zero for $5 pretty much put the nail in the coffin when it comes to IoT ( Internet of Things ) work for prototyping.
