Cost-effective and self-regulating digital Noticeboard systems

Traditional noticeboards in schools and colleges amount to heavy wastage of paper. Misunderstanding between parties involved is common. In this paper, we interface multiple Computer Science concepts and study a cost-effective way of solving the problem through smart noticeboards. We use a Raspberry-Pi single board computer with a perpetually running python script which uses the tkinter library to handle images. The notice board module pings the server every 30 seconds to check the offset of local data and the database on server for necessary updates. The update is followed by auto download of new images from google drive.The system is powered by a nodeJS backend to achieve good performance. We introduce a number of new concepts in this domain to digitize noticeboards to full-effect at a pretty economical price.In this paper we have also given a solution, cloud enabled smart display boards for automating the pro-active disclosure as part of smart village concept proposed by Department of Rural Development Ministry of Rural Development Government of India.
