Picture of 9V Lantern
I had two goals with this, one don't solder and two make it like post over on gizmodo showing a 9V Lantern.

I had recieved a few emails about making things without soldering, I guess to some thats intimidating. So here I skipped that complicated soldering process...

Step 1: Parts

Picture of Parts
9v battery
flashlight bulb
bulb mount
film canister
9v battery snap connector
hot glue
for the 9v snap connecter i use old 9v batteries. if you have never noticed, 2 9v batteries can be linked together and they can overheat (and catch fire?). if you CAREFULLY take apart a dead 9v you can harvest the top piece and use it instead of buying them. dont hurt yourself tho.
You can also link together an infinite number of 9volts and make a super battery and take over the world!
Yeah i linked about 20 9V(some half dead some more than half)And i reached 60 volts! WOW I put it to a tiny 5V motor(like those from cheap fans) and put it there and it spun like superfast!(it smelt bad though,for some reason)

i linked 7 rechargeable 9v batteries and got 63v.

Aha, Mine where half dead, if not completely dead...

why not use a Christmas tree bulb? should be at least 4v though.

my precious flashlight bulb burned out as soon as i connected it to the 9v battery
too bad ill use it as a bullet know
wow,this is actually useful since mom won't tell me where the soldering iron iron is (even though i'm way better at soldering than her).
My mom hid it from me too, but it was because I left it on all night....

Just a heads up. Astroblade -- You're using a lightbulb from a standard (2 AAA - 2D cell) flashlight, aren't you? :-) Try grabbing a bulb from the camping department meant to work with 9volts, not a normal 3 volt variety. Or, in the name of hacking, open your case, remove 2/3rds of the cells, if they look like AAAA batteries, just cut 4 loose with scissors, poke a hole, and rewire to the terminal. Slip the bottom cover back on and fix with some superglue.
my batterie had this green cassing alkali butt it was filled with something that made my skin burn

I worked in shops all through college and then I am a pack rat when it comes to bike parts! Waste not want not... -Joe
Just stop by a bike shop and you can walk away with at least a dozen sprockets. Did that for an art project last year.

How long does a battery last with that "current" setup? (no pun intended)

Hey if you don't want those bike gears can we work out a trade or something?

Enough of the flashlight, how do you build the Saw Blade Desk type thing!
ummmm its just halve of a bike gear

It might be easier to glue the socket to inside of the lid, then glue the battery connector to the outside of it and run the wires through a small hole in the lid.

cool idea. it would also look cool if, instead of bike sprockets, you used old circular saw blades. just a thought,

ok, thanks again for the tip on radioshack. i started putting the lantern together but came up on a problem when every time i connected the battery and snap connector, with bulb and mount attached, the bulb would overload and burn out in a burst of lite. any suggestions? just in case it made a difference, i used a mount that uses a screw and bolt to secure the wires.

I just made an led version. works very nicely. I used a slightly different design though, the led sits on the inside of the cap, with the terminals off an old 9v bettery protrduding through two holes in the cap. I had an idea to put an orange led inside, then draw a jack-o-lantern on it with a sharpie for halloween. or put red and green leds in them and hang them on your xmas tree..

i was really wondering where i could get all those parts. specifically the flashlight bulb, bulb mount, and the 9v battery snap connector? would a walmart carry all the items? do i have to get the snap connectors online some where?
joe (author)  astroblade8 years ago
You can get all of the parts at Radio Shack. I guess it would cost around $5. Have fun! -Joe
what about that little table/stand thing that you made out of old bicycle gears, I'd really like to know how to make that.
if u make a tic tac one u shud scratch the inside or outside to make it foggy for better light distribution. the halloween and xmas idea is great also!

I guess making it LED-based would just complicate things, but at least it would last a lot lot longer. I was thinking a TicTac container would work great too.
