Lights are one of the most essential items that any backpacker would consider in his checklist. Among all the light sources which a backpacker chooses, headlamps are the best. This is because, a typical headlamp has its own advantages and practical applications. One can always argue that it can easily be replaced by a handheld flashlight or torch. But our own safety is the number one priority that matters while living outdoors. During certain situations when our survival matters the most, our hands may not be free all the time to hold a flash light. So it is always better to be hands free. Moreover, these headlamps can be strapped anywhere. Also, one can always keep the headlamps in their hands anytime if it makes them feel better. Hence it can be used for camping, hiking, biking and various other creative applications. Overall, Headlamps are a must for anyone who wishes to have a safe night hiking experience. In this Instructable, you'll be able to learn how I made my own 3D printed Headlamp and the circuit that I used to make the Headlamp reliable and long lasting. You might wonder what is the need for doing this project when there are so many cheap headlamps available in the market. Please beware of such cheap products. Most of those products don't contain constant current sources to drive the LEDs. They may stop functioning any time. Hence they are not that reliable. There are some products in the market that contain constant current circuits too. But they are too costly. So to cherish the joy of making and learning how a professional headlamp circuit works, this is the right place. The main features of my headlamp are 36hrs of battery back up under Low power mode and 10hrs of battery backup in High power mode. It can be attached to any head ie it is that flexible to use. https://www.instructables.com/id/3D-Printed-HeadLamp-With-Constant-Current-Circuit-/ For more info on how to do it, please visit the above link.
