There are plenty of hand crank flashlights on the market and they also happen to be relatively inexpensive. The best part about these types of flashlights is that they don’t require any disposable batteries and in many cases rely on a capacitor to store the energy making them a very eco-friendly device. Many people use these types of flashlights as emergency lights in case of power outages. They are also ideal for camping and vacation homes/cabins in remote locations.
Although they are inexpensive, what if you could actually make one as a DIY project? Sometimes it’s just about the satisfaction of actually making something on your own using off the shelf components. The owner of Tesla Maker has come up with a pretty cool 3D printed version of a hand crank flashlight called Tesla Torch.
Tesla Torch Introduction
It’s been designed in such a way that many of the 3D printers on the market are able to produce the casing for the Tesla Torch. What’s impressive about the flashlight is that it delivers an amazing one minute of light for every second of hand cranking thanks to clever use of electrical engineering and design. The super capacitor is capable of providing 30 minutes of light and recharging it will only take you seconds. If you don’t have a 3D printer, don’t worry too much. There are also plans on releasing details where you skip the 3D printer and use other methods to make a casing for the components.
The developer has not only made the plans available at LaserHacker but also an entire video on how to build the Tesla Torch fast charge flashlight.
