Summary

The "Space Beam" flashlight was offered by EverReady in the 60's. Besides owning one when I was a kid, the flashlight has a great name and a classic design, so I thought it would be fun to design a modernized version of it that still maintained the original lines. I made it for myself and have been using it for over a year. The one picture is lighting a tree 50 ft. away in the pitch dark. It works very nicely, and I find myself using it all the time. It throws so much light, that it can be placed practically anywhere in a room and pointed at the ceiling to act as a work light.

But recently I saw 'Indiana Jones and the Dial of Destiny', and in the scene where (spoiler) they find Archimedes’ tomb. I realized that they were carrying a Space Beam! So I decided to post it so others could make it.

This design uses Lithium batteries that are used in robot vacuums and have smart Battery Management Controllers (BMC) built into them. The BMC allows the batteries to always be connected to power when not in use, but prevents the batteries from ever being overcharged. BMCs also provide overcurrent and short circuit protection, which can cause fires. Left on the chargers when not in use, the batteries can be fully charged every time you use the flashlight.

Read the "Indy Flashlight Build Notes" PDF file for the details of the assembly and the parts that I used.

Note the STL files are high-resolution (so the prints have no visible faceting) so they are large.
