I saw a really cool video of a PC case called “Snowblind“, that had a transparent LCD Screen as a side panel. I was amazed over how cool it was. The only problem was that it was really expensive. Therefore, I tried making my own! In this instructables I will go through how I…
This uses a buck converter as a 5V Output to charge the battery(Li Po/Li-ion). And Boost converter for 3.7V battery to 5V USB output for devices needed 5 V. Similar to the Original system that uses Lead Acid Battery as an energy storage charge by either PWM or MPPT controller. And supply for 12V Devices. This One only uses…
Each inductive load, such as a motor or a transformer, produces an inrush current at startup that increases as the power of the device increases. This is because at start-up only the very low resistance of the windings is seen, before the flux created opposes the passage of current. This current spike could cause the…
You know the pressure sensors placed inside the car seats that remind you to fasten your seat belt? The professor Michele Maffucci has decided to exploit this principle in order to create a system that measures the sedentary lifestyle of people sitting at the desk, but with a DIY pressure sensor and a PIR sensor….
In this project we are going to learn how to build an infrared based non-contact thermometer which can be utilized for screening people at schools, offices, shopping malls etc. for abnormal body temperature which could be a sign of contagious diseases. The proposed non-contact thermometer can measure body temperature of a person at forehead…

There’s a million different ways to do…
Using a bit of tech to make up for a lack of skill is a time-honoured tradition, otherwise known as cheating among those who acquired the skill the hard way. Learning to wheelie manual a skateboard is usually paid for in bruises, but [blezalex] got around that by letting his electric skateboard handle the balancing act. At…
Modern woodworking tools are amazing, allowing you to make any number of useful or decorative objects from the comfort of your garage. Unfortunately, they also produce a lot of dust, so YouTuber “Atomic Dairy” came up with the idea to install an air purifier that can cleanse the shop air eight times per hour. This…
