There are mobile payment apps which allow you to pay via QR code. But I couldn't find any app that would work on desktop e.g. via special URI. So here's my idea:
Create a universal URI scheme for payments that can launch a handler app (just like mailto: URIs can open your e-mail client). This app could then send wire transfer instructions to your bank account via public internet banking API (if your bank has one). The app would also have a server-side e-shop module for payment processing which would allow instant checkout (if you bank supports instant wire transfers to the e-shop's bank account).
Extra features in Czech Republic:
- Company verification via ARES business registry
- Company bank account verification via ADIS tax registry
I already have a simple tech demo in C++/Qt5 that can verify the company and bank account. The main task would be finishing at least one bank API module and improving UI.

Create an Android app for Syncthing as part of the Syncthing Tray project by mkittler
Description
There's already an app but code/features already in Syncthing Tray could be reused to create a nicer app with additional features like managing ignore patterns more easily. The additional UI code for the app could then in turn be re-used by other parts of Syncthing Tray, e.g. to implement further steps in the wizard as requested by some users. This way one "UI wrapper codebase" could serve GNU/Linux, Windows and Android (and in theory MacOS) at the same time which is kind of neat.
Goals
- DONE: Learn more about development for Android and development of UIs with Qt Quick
- DONE: Create an experimental app reusing as much existing Syncthing Tray code as possible
- DONE: Build Syncthing as a library also for Android and use it in the app (already done but needs further testing and integration with the rest of the app configuration)
- DONE: Update the Syncthing Tray website, documentation
- Extend the app so it has at least a start page and an import that can cope with an export of the other app
- Update forum thread
- Upload an experimental build on GitHub
- Extend the Syncthing API to download single files on demand (instead of having to sync the whole directory or use ignore patterns)
Resources
- Android SDK/NDK and emulator
- Qt Quick
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)

Sipario, less mobile phone, more social interactions by baldarn
Mobile phone usage is addictive. There are adults addicted, but a huge problem is kids addiction We must do something to help avoid problems in this context.
The solution
Sipario, an app and community aggregator in order to help with smartphone addiction.
Description
The more you use Sipario, the more points you earn. If you use the smartphone, you will lose your points
Business model
How is this sustainable?
I personally don't care, but sutainability of the business is key to possible investments.
Sipario will allow commercial entities to join the network. The idea is to give commercial activities (eg: restourants, cinemas, theathers, ....) the ability to certify that users are not using the smartphones during the permanence in the place. this will allow then commercial activities to give coupons to users, in order to promote a good behavior and retain the customer
Tech challenge
if resources allows it, i would like to create an algorithm that leverage bluetooth for certify people proximity presence in order to avoid attacks from points rouge in the context of the app
Goals
Deliver:
- android app
- IOs app (some apple developers must join in order to do this)
- backoffice app
- BLE algorithm to certify nearby presence
