Steampunk Flashlight How to Make




About: There is no greater harm than that of time wasted - Michelangelo Buonarroti

In this instructable I will try to show you how to make a copper and brass Steampunk Flashlight. I will try to make this in 3 sections.
1. Back section/On/Off button and battery case

2. Middle section/vacuum, tube

3. Front section/lens holder

Step 1: Materials and Tools

Materials needed:
copper tube

copper tube cap

copper tube fitting

round brass tube 1mm

small brass screws

brass sheet


cree led

led driver

vintage vacuum tube

red transparent plastic

led with driver

18650 battery

on/off button

I recovered the led's, on/off button and led driver from old small flashlights


Heat Torch

Metal sheet cutter

Copper tube cutter

Drill and drill bits

Metal file

Soldering iron

Super Glue

Fret saw



Dremel Tool


Step 2: Back Section/ On/Off Button and Battery Case

Start by cutting a brass strip using the metal sheet cutter.

Use a small drill bit to make holes at a distance of about 0.5cm.

Cut the small brass screws using the Dremel tool and put them in the holes.

Use flux and the heat torch to solder the screws on the brass strip.

Use the sander to flatten the back of the brass strip.

Use the brass strip to make a ring around the copper tube cap.

Use solder to join the two pieces.

Use a drill bit to make a hole in the middle of the copper tube cap.This hole is for the on/off button.

Cut a piece of copper tube longer than a 18650 battery.

Insert the on/off button and use superglue to hold it.

Add the copper tube cap and use superglue to hold it.

On the other end add a copper tube join fitting.

Make a hole at the end of the fitting.

A screw must be inserted here to hold the back and middle section together.

Step 3: Middle Section/vacuum Tube

Start by cutting an oval piece of brass sheet using the metal sheet cutter.
Make holes and use a fret saw to cut a hole in the middle of it

Use the same method used on the brass strip and solder the brass screws on it.

Cut a piece of copper tube longer than the vacuum tube and make a rectangle hole in it smaller than the oval piece.

Solder the oval brass sheet piece on the copper tube.

On the other side make holes and insert a piece of 1mm brass tube.The tube will hold the positive (+) wire.

Insert the vacuum tube and use superglue to hold it.

Glue the red piece of plastic on the back of the vacuum tube.

Insert the led module that will light the vacuum tube and solder the negative (-) terminal on the copper tube.

Solder the positive (+) wire in the middle (positive terminal) of it, this will transfer the electricity to the main led in front of the flashlight.

Step 4: Front Section/lens Holder

Use 1mm brass tube to make a ring and solder it to the negative terminal of the main led driver. This will help to make contact on the copper tube and also to hold it.
Solder the positive (+) wire on the positive terminal (+) of the led driver .

Use a smaller copper tube and brass tube rings to hold the lens.

Use superglue to hold it Insert it and glue it to the front section.

Step 5: This Is It! :)

    Nice torch but it's a shame you cut the legs off that "magic eye" valve for it! A bit more work (well ok a lot more work) and you could have got the magic eye to light up in the side window and indicate temperature or your heartbeat or something. But that would eat up the battery and make the torch pretty hot to hold too but hey!

    That is a very good idea :), I am working on a big 100w led steampunk flashlight and I will try to make something like that on it. Thank you!!

    Don't hold sheet metal by hand when drilling, it becomes a spinning Guillotine. I was almost unlucky once. I am very impressed with the work and final build.

    Now I know that :), learned it is sharp, the hard way. I had a metal sheet in the small machine vice, it fell off the bench and I tried to catch it :).
