It's a lever switch
Sorry - not selling them
The little 12v ones (which I didn't use in the end) - you can find these on eBay by typing in "27A battery"

Updated. I have put a link into the parts page and have put a little info in step 10 on the sight. Thanks for the heads-up

Thanks. I've used flint and steel plenty of times as well. Does take a little practice to get the embers to catch - the right amount of tinder definitely helps. Oklahoma sounds like a crazy place man
I think this comment wins hands down as the longest I've seen! You are right though, this isn't a simple fire starter. Check out the link in the intro though if you want to see how to make one (This is mine also). This version is more slimline and has a better finish though.If you have any pictures of the one you have made, are you able to post them? If not, you should write up your own ible' over the thanksgiving holidays.
Great idea! This would look even more amazing if you added an LED to each of the bottle lids and a small 3v barrel! You could make it so the LEDs only come on when the bottle is screwed in all the way.
Interesting. Here in Australia, Methylated spirits is pretty benign. The SDS has it as highly flammable but that's it. I had a look at the Methanol SDS and it looks pretty potent. Def use lighter fluid if you have it around,. The ible' though is about using other sources of flammable liquids as a lighter source.
That's excellent! I might include your way to make the groove in the ible' if that's cool.Post some photos too when you get a chance.

Ah yes - very good point. I've added a little more info in the ible' on what methylated spirits actually is. :)
Anytime. Totally agree with being able to make something yourself. I think people forget sometimes that this is a DIY site!
Your da man
I find that the larger bic lights have a pretty decent sized flint inside
Thanks for the heads-up. I've updated the ible'.
Oh and let me know how your fire piston goes. More than happy to help if you get stuck in any place.
Love the look of this little fella. Great sound too for such a simple amp.

Hey there.There is a small door on the timer that hides the buttons. I just had a look at the link and its bringing up the corrct timer
Great job! Def a good use for an old camera.That looks like a Voigtlander camera on the bench behind tour camera lamp.
Gotcha. Yep it would be, especially if you also had a drill press too!
I use a paste flux which always does a great job of bonding the solder to the copper. you will know when the copper is at the right temperature when the flux starts to bubble.
Damn impressive build man. Love your daughters gun as well - did you also make this?

Getting the holes for the spark wheel to line-up is tricky. Doing it before you make the bends would take some serious skill.
yep. You could attach the flint and spark wheel with a key ring to the torch somewhere. Then you'll always have it ready to use
Do it! Actually, if you are new to soldering copper, then this would make an ideal project to start with

You may be able to modify a bike pump if you blocked the valve up on the end of the pump
Of course a lighter is going to be easier. This is an ible' though on how to make fire without one.
None at all. I just wanted to make mine more compact.
Yeah it does. The lens is from an old projector that I had lying around and it has a "zoom" feature so you can adjust the spread of the light. It doesn't spread a huge amount but it does the job

As long as the copper tube and dowel are around the same size then you should be ok. The dowel should fit loosely into the copper tubing so when you add the O ring it will form a good seal. In regards to lint - yes I have used this before as tinder but no in the fire piston. I'll give a go tonight and let you know if it works
haha - I have no idea how big a quart is but def good to hear you'll now have multiple uses for it. I've just been using everyday motor oil and it does seems to work well.
Cheers! Yeah they would be great gifts. You could put them into a box like the one shown below (you can get them on eBay just type in "wooden pencil box") and include a little tin with some char cloth.
I thought I had!. Have now :)
Nice work! Did you have any issues fitting the LED's into the bamboo? Maybe for the arms you could add some internal tooth washers like in the image below. It would def help lock the arms better. For weight you could also add a few flat lead sinkers...

Don't see any issues with doing that.
Howdy,Yes it does. If your play button isn't staying down I'd say your going to have to find another tape deck to use. I cut the motor wires on mine and didn't have any issues, as a last resort you could try that.
I would always take a lighter as well. This is just an emergency, back-up option. Something that you can clip to your bag and forget.
Cool - updated
Yes it shorts the battery but it's for a very short time. You won't have any issues with it going Kaboom.
Most Def - see the above comment on a ible' that I made using lint and wax
Hey there,That's correct. You are just using the timer as an on/off switch. I'm not a 100% sure that this will actually work without testing it first though. I don't see any issues with it so it should. All you want to do is to cut the power to the antenna 5 minutes after it has gone down, shutting the coop door for the night. It then needs to return power 5 minutes before the other timer kicks in and raises the door. The only thing that may go wrong is cutting the power might make the antenna retract. Don't think t will though.
Nice idea! I've added - just waiting approval :)

Finding suitable arms and legs I think, is one of the hardest parts in making a junk bot. Then trying to work out a way to attach them is a close second. If I need some inspiration for arms and legs, I usually just check out google and see what others have done.Loving the look of the first junkbot by the way.
Hey there,That's actually a really good idea. I'm going to do some more experiments this week and see if I can improve the sound. I have a few 1k pots at home to play with.
You would also have to connect the 2nd timer to the battery positive and negative as well if you wanted to set-up your auto door with 2 timers
sweet. I wonder how they did that.. I might have to do some research to find out.
aha! yes I'd see how this would work... Might give this a try next.
Nice one. I like the idea of having to spin the turntable while you play!
No problem. if you get stuck, let me know and i'll be happy to help.
Hey Tamie,Don't really worry about the info in the discussions. These are just some ideas that people have had to help improve the build. Honestly though, I have been using my original set-up for over 2 years and haven't had the need to change anything. Just follow the original instructable that i wrote and you'll have a great working chicken coop door. The only thing that I have to change every 6 months or so is the battery as they don't really like being charge and dis-charged every day.. Other then that, you won't have to ever worry about not shutting the coop door.
