How to enable RaspberryPi Camera module on Ubuntu

#blog #howto #raspberrypi #camera #ubuntu

I’m running the official Ubuntu for RaspberryPi on a RaspberryPi 4 and wanted to use the RaspberryPi Camera Module. The thing is, this is not as simple as it is on Raspian. So here are the steps you have to perform to use the Camera Module on Ubuntu. Activate Module First of all connect the Camera Module to your RaspberryPi like you always would and boot it up. Next you have to add the magic setting “start_x=1” to your /boot/config.

 

RaspbeeryPi Pico Temperature Light and Logger

On a rainy sunday afternoon I found out that the RaspbeeryPi Pico fits perfectly into a 35mm film box if you cut a little hole for the USB port into the lid. Since my box was a semi-transparent white box, I decided to add some LEDs and build a little temperature sensor, that indicates the current temperature range using either a blue, green, orange or red LED. Build I connected the power pin (long side) of each LED to a GPIO port (green = Pin4, blue = Pin5, orange = Pin3, red = Pin2), of course with a 220 ohm resistor in between, and all the short sides to GND.

 

How to develop on a RaspberryPi Pico using Micropython

A few days ago I got two brand new RaspberryPi Pico Boards and so it is time to build something using this new toy. So let’s talk about what it actually is, how to setup a MicroPython development environment and also build a simple example project to make sure everything works as expected. This one is not like the others I won’t go to much into the specs of this board, since you can read them for yourself here, instead I will focus here on two specific things that set’s this Pi appart from others like it.
