Wonder Wall: Interactive Origami Art with Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi

Wonder Wall — an Orginal Meditation Mural, by origami artist Ross Symons, gives motion to the artwork using Raspberry Pi and Bare Conductive’s Pi Cap. Here’s more from Raspberry Pi Blog:

Ross named his creation “Wonder Wall – an Origami Meditation Mural”. Visitors put on headphones next to the origami flower wall, and listen to different soothing sounds as the Pi Cap senses that one of the green flowers is being touched.

64 origami flowers were mounted to a canvas, a much lighter and more readiliy transportable option than a big wooden board.

Add Ethernet to Raspberry Pi Pico #piday #raspberrypi @Raspberry_Pi

Add ethernet to your Pico this weekend with help from Raspberry Pi Blog:

Raspberry Pi Pico has a lot of interesting and unique features, but it doesn’t have networking. Of course this was only ever going to be a temporary inconvenience, and sure enough, over Pi Day weekend we saw both USB Ethernet and Ethernet PHY support released for Pico and RP2040.

Playing Star Trek Sound Effects with the Raspberry Pi Pico Using CircuitPython @Raspberry_Pi #PiDay #RaspberryPi

Raspberry Pis have a long history of use in the performing arts, special effects, and cosplay. So naturally the Raspberry Pi Pico is getting into the mix. Michael Horne has a long-running Picorder project, and he’s using Raspberry Pi Pico for sound. Here’s more from the Raspberry Project:

To start with, I looked at creating my own circuit and using PWM Audio. This post from Greg Chadwick indicated that I could do just that. However, it was, excuse me, a bit beyond me. It also used C/C++ as a programming language. I had already decided that, for this project, I would use Adafruit’s CircuitPython derivative of MicroPython. There were a lot of libraries, it is, basically, Python (which I can already use to a certain extent, thanks to the CamJam EduKits and all the other tutorials that are available), and it is extensively documented.

However, that blog post, and some previously-read Pico documentation, pointed me to needing to use I2S audio, which is how audio (DAC) boards work with the Raspberry Pi. This would give me high enough quality audio to play my sound effect and give me a bit of familiarity (which I always think is key to understanding how to do something).

Using a Raspberry Pi 4, the VLC video player and Node-Red to implement a simple signage type application.

Live Energy Monitor with Raspberry Pi

In order to optimize power usage from his home solar panels, Frederick put a Raspberry Pi + Unicorn Hat to work as a custom energy monitor. Now he knows whether he’s taking from or giving back to the grid.

We recently had a digital electricity (and gas) meter installed by Fluvius. In order to make more efficient use of our solar power, I installed a little dongle from HomeWizard to the P1 port of the meter. Using an app, it is possible to monitor electricity taken from or pushed to the grid. The idea is then to use the bigger appliances (dishwasher, washing machine, etc … ) when there is leftover solar power available, rather than push it to the grid.

Code and a full explanation of the install process are available here.
