Localtunnel
My last project was for a company in the UK. This lighting company has devices with a http webinterface, which can only be approached locally.
I made a Raspberry Pi, active in the network of his customer, which make a https connection, available anywhere at internet, using localtunnel (installed at our own server). The Raspberry Pi uploads the public URL to our website.
Digital Signage
The system retrieves contents from a website and shows it a display. For each part of the day you can specify different content:
- coffee and cake in the morning
- sandwiches during lunch time
- beer in the afternoon
QR scanner
System used in Corona period. The system scans a QR code, decrypts it, check the validity and gives premission for the guest to enter or not.
The scanner is able to read information from a passport or ID card, comparing it to the name in the corona-QR code.
Sending and receiving SMS messages
For an existing system I added an option to send and receive SMS messages using a Raspberry Pi and GSM board.
Alarm detection for hospitals
For a British company I developed a system that detects help-requests from patients in hospitals, reading the serial port. The system delivers the requests to a server to contact a nurse.
The Raspberry Pi has to be reliable and stable.
Scanning e-tickets
For a Dutch company I developed a system that reads e-tickets from a QR code, checks the validity at a server and opens a gate.
The guests entered three times quicker than before, scanning with a hand held system.
