Getting CCTV streams in Python
I have basic CCTV setup at home with two bullet cameras on 4 channel hikvision DVR. Hikvision DVR does not offers face detection, vehicle detection or any other image processing functions with basic cameras. I thought it will be worth to get CCTV feeds in python and then do try out face detection etc on […]
Programming nodemcu on micropython firmware
NodeMCU board is based on ESP8266 wifi chip. It is an affordable board for IoT, robotics and other embedded programming projects. So far I have used NodeMCU with Arduino to build IoT relays, IoT doorbell and program a number of sensors. NodeMCU and micropython together make embedded programming really simple and easy. To start with, […]
Monitor power usage and other parameters of Linux server
This weekend I decided to exchange my 8 year old i3 laptop with a desktop. I was offered an HP elite 8300 small form factor desktop in exchange of laptop and 7000 Rs. So far I was using raspberry pi 3 for hosting web based apps and running some other programs 24×7. I mainly opted […]
Machine learning using decision tree algorithm in python
Decision tree algorithm is very basic method to predict result of given input using the pre-known data (knowledge) . Let us see how this can be used in machine learning to do predictions. To start with, you need python scikit-learn module Think of a problem statement…say predicting a domestic animal with its height, length and […]
ACS712 current sensor with NodeMCU
When we buy an electrical appliance we trust that the load mentioned on specs is correct. Let us try to build something to measure actual power usage of a 220V AC electrical appliance. ACS712 is available is 5A, 20A and 30A current rating. This sensor works on the principal of Hall effect. From the data […]
