I received 4 large boxes from element14 yesterday - two of them contained prizes from the Pi-Fest Music Tech Challenge, so of course I had to post a blog about what was in the boxes:

Final Goals
So far we have tested and verified that all of our individual pieces of code work. Now it’s time to integrate them and debug any problems. Let’s start with our Pico named Bob. Bob reads audio from the mic, encrypts i...
Tiny Jambu Encryption and Decryption
The Tiny Jambu algorithm is a lightweight cryptographic algorithm written in C by Hongjun Wu and Tao Huang and is available here. We started by testing the encryption and decryption functions from the Tiny Ja...
Microphone and Speaker Modules
Our microphone and audio decoder use the i2s protocol, a protocol for sending and receiving audio. Below is the i2s timing diagram.
Figure: i2s timing diagram
Basically the code should set the ws, then send a bit of da...
Final ThoughtsIt was a nice project and I enjoyed experimenting with the pi pico. It has proven to be a very versatile MCu of very low cost. It particularly stands out because of its 2 cores, nice form factor, the PIO state machines and large flash m...
The parts - so far.
Lets quickly touch on the "design process", it is somewhat akin to the walk and build or design on some paper you had on your desk, more than the lets just play it by ear and see how it goes, but by no means any feat ...
Overview
from the back, assuming your jumpers are reasonably rigid with the 7 of them in two loops connected to the Pico Pi, they double up as part of the back of the stand! Magic

Hi, all! This time I've been working on putting it all together and making it work. There is the audio part, the touch sensitive ink part and building of the drum.I used white glue for the faux leather and a mix of Liquid Tape and powdered g...
Overview
Design files:
I have zipped the Matrix button pannel v3.f3d, which is the Fusion 360 design archive file. This has my sketch, design, and all details which you can bend and use to your hearts content. 3D printed, it is a near perfect fit ...
Mea Culpa
My post it note has the challenge end as the 29th July. This is wrong I have found out this morning. It did in fact close on the 14th July. This is 100% my own error, my apologies to the E14 team on this and the other entrants.
The Project(...
Hi all ! Hope everyone is well.
This project was very fun to do. I've learned a lot, specially discovering that technology can help protect this little (and not so little) feathered friends.
I've learned more about Machine Learning and Tiny...
Hi Everyone,This is the final blog of this project , explains the overall concept and works. The previous blogs are listed hereBlog1 , Blog2 , Blog3, Blog4 Concept The concept of this project is to play background music on a person entry. ...
We decided to install FUZIX onto our picos in order to run programs written in different languages. The Fuzix operating system is a Unix clone made to run on small platforms like the Raspberry Pi Pico. After taking a look at the Github we realiz...
This is the Continuation of the Blog #5.
Here I have used Raspberry Pi PICO, Max4466, and SSD1306. All the code is developed and Flashed using the Arduino IDE(Steps to Follow to Setup Please Follow Blog 4.).
Now Working:
Visualizing the Frequ...
Raspberry Pi Pico MIDI Box: Blog#5 Time For Truth
Now we have come to the last blog and it means we need to put to test the MIDI we build so far. To test the MIDI I decided to use the FL studio which can be downloaded here. Once you have downloaded ...
Raspberry Pi Pico MIDI Box: Blog#4 Let's Code
So once we have put the hardware together, now we can start to code. For the coding, I have decided to use Circuit Python. And to test the MIDI I decided to use the FL studio. First, let's look at ...
In the previous blog (blog3), i have interfaced Neo Pixel LED's to pico. In this blog , Iam going to eliminate the breadboard and pack it all together into
the wall mounting switch board.The size occupied by the components in this design,Speaker - 2 ...
Hardware Design
This section will describe the circuit design using the Pico and other electronics.
The hardware components used are PICO, Microphone MAX4466, and the OLED display SSD1306.
The Software Implementation: The code
Here I have used the ...
Playing with Raspberry Pi Pico #3
Hi, today we will talk about the project I want to carry out and, in particular, about the acoustic sensor that I will use.What I want to create is a system that, using two microphones, allows me to recognize the dir...
Hi, as I said in the first blog, the purpose of this work is to acquire the knowledge of Raspberry Pi Pico board and to start using it for simple applications. I will use these blogs to introduce my students to the use of this board and its programmi...
In this blog post I'll be building the actual instrument. One of the challenges is to have it remain portable and light. It must also be the same height as an actual tabla (when assembled). Also, the player should be able to adjust...
Raspberry Pi Pico MIDI Box: Blog#3 Putting It Together
In this third blog, we would like to put together what we have constructed so far. In the previous blog, we have seen how the idea came about and in the second blog, we have seen the hardware th...
Playing with Raspberry Pi Pico #1
Let's start
Hi, I'm a teacher and, for a couple of years, I've been using simple Arduino boards to make simple projects.My aim is to stimulate the curiosity of my students and to let them know how simple...
