Use ESP-01S as WiFi to UART bridge
Project Description
Currently with just with 8 RPi devices cables occupy most of the space in the 'rack. Reduce the clutter with replacing USB to UART converter with WiFi to UART ones.
Goal for this Hackweek
- Devices are ordered
- Prepare device programmer
- Study platform
- Create clean WiFi to UART bridge implementation

SUSE Prague claw machine by anstalker
Project Description
The idea is to build a claw machine similar to e.g. this one:
Why? Well, it could be a lot of fun!
But also it's a great way to dispense SUSE and openSUSE merch like little Geekos at events like conferences, career fairs and open house events.
Goal for this Hackweek
Build an arcade claw machine.
Resources
In French, an article about why you always lose in claw machine games:
We're looking for handy/crafty people in the Prague office:
- woodworking XP or equipment
- arduino/raspi embedded programming knowledge
- Anthony can find a budget for going to GM and buying servos and such ;)
Grapesss: a physical Shamir's Secret Sharing application [ESP32-C3 + Mobile] by ecandino
Description
A couple of years ago I created StegoSecretS, a small cli used to encrypt and split a secret into multiple keys, using the Shamir's Secret Sharing algorithm.
The idea is to re-implement the project using physical devices. One device alone will be useless, but when close together they can be used to decrypt the secret.
On a practical side the user encrypts the secret with a mobile application. The same application is used to split the secret, and load the partial keys into different micro-controllers. Another user will be able to decrypt the secret only having at least N devices close together (using the application).
I'm planning to use a couple of ESP32-C3 I bought, and build a very simple Android mobile application.
Goals
- Learn about Rust and micro-controllers (ESP32-C3)
- Learn about mobile applications (Android and Kotlin)

Add a machine-readable output to dmidecode by jdelvare
Description
There have been repeated requests for a machine-friendly dmidecode output over the last decade. During Hack Week 19, 5 years ago, I prepared the code to support alternative output formats, but didn't have the time to go further. Last year, Jiri Hnidek from Red Hat Linux posted a proof-of-concept implementation to add JSON output support. This is a fairly large pull request which needs to be carefully reviewed and tested.
Goals
Review Jiri's work and provide constructive feedback. Merge the code if acceptable. Evaluate the costs and benefits of using a library such as json-c.
FizzBuzz OS by mssola
Project Description
FizzBuzz OS (or just fbos) is an idea I've had in order to better grasp the fundamentals of the low level of a RISC-V machine. In practice, I'd like to build a small Operating System kernel that is able to launch three processes: one that simply prints "Fizz", another that prints "Buzz", and the third which prints "FizzBuzz". These processes are unaware of each other and it's up to the kernel to schedule them by using the timer interrupts as given on openSBI (fizz on % 3 seconds, buzz on % 5 seconds, and fizzbuzz on % 15 seconds).
This kernel provides just one system call, write, which allows any program to pass the string to be written into stdout.
This project is free software and you can find it here.
Goal for this Hackweek
- Better understand the RISC-V SBI interface.
- Better understand RISC-V in privileged mode.
- Have fun.
