A PC-based schoolbell system for elementary schools from scratch deployed in 2013. The software is able to handle holiday work schedules, shorter classes and many other irregular situations. The system is easily manageable through the Internet and is able to work practically without any user interaction.

The system uses the existing (legacy) classic bell system (230 V ~ 50 Hz) operated by a custom hardware, but the software can easily be adapted to audio output with the possibility of playing different sound effects in a specified manner.

A complex aural-visual railway passenger information system originally as a "temporary solution" to several, medium to small sized Hungarian railway stations.

It was followed by a contract to replace the passenger information system on one of the biggest regional railway stations in Hungary: to both re-use the existing visual boards and displays, and to install several new ones, to make the system compatible with the existing 100 Volt audio system, and such other challenging duties.

The initial task was rather simple: to follow the entries and exits of the staff of a five-day-long high school freshmen's camp. The equipment consisted of two industrial barcode scanners which were set at the main entry at the gatekeeper's stand, and barcodes were placed on the ID card of the staff.

After the bigger overhauls in 2018 and 2019, the system is now based on Microsoft SQL Server and is able to function in multi-workstation environment. Lots of extra features got introduced, among others: GDPR compliance, better search/filter features, TTS (text-to-speech) support and even more, thankfully to the direct communication between the developer and users.

Management of the budget (cash, various bank accounts, savings deposit...) of a student-council: organizing the incomes and outlays, deposits, transfers, generating receipts with ease. Not just following the financial situation, but pre-planning the budget in a proactive way for e.g. the next school year, and other various challenging tasks.

By connecting the system to the RFID access control system of their office, expanding it with a task management (ticketing) and an HR module, the student-council got an integrated system that makes their daily job easier like never before!

Thankfully to its web interface the application is available from all around the world, and with its API feature other applications can be linked to it, which can result in automatic income registering, and so on.

Wiring four offices + accessory rooms, establishing a reliable Ethernet wired and wireless network with professional MikroTik devices, and implementing domain services, file sharing and requirements for better collaborative work with the help of the Microsoft Active Directory.

Breaking up with the current centralized smart home trend, engineering totally new principles and hardware-hardware & hardware-software relationship. Combining the advantages of standalone and centralized systems to a modular HUB in favour of implementing various automatisms.

The result: less wire than with the other smart home technologies, and a flexible and universal backend with a customizable frontend where the users can check (and manage) all their smart home devices.
