Build Your Own Tent Lantern
You can buy yourself a small lantern that will fit in a tent cheaply enough , but where’s the fun? If you are looking to create your own, tailored to any specifications, Adafruit has a guide.
By the end, you will have a not-so-bright lantern, but it illuminates the tent enough for you to do whatever you need to do. Apart from some soldering skills, you only need a few parts, including a battery, a few LEDs, and a case. If the lamps on the market don’t suit you, this is one way to make yourself one that behaves exactly the way you want.
