With Instructables you can share what you make with the world, and tap into an ever-growing community of creative experts.
To protect the wire, I recommend two or three layers of heat shrink in successively shorter lengths and larger diameters to create a rat-tail grommet.But slide the smaller heatshrink up the wire BEFORE you solder, or it won't go over the plug.
When the nut is fixed to something, the rotation of the screw thread converts the rotary motion into linear movement. (Exactly the same as the fan belt adjuster on your car.)
The boost converter to 33V will not be needed if you put three 11.1 V batteries in series. This will save on efficiency and increase battery life.As you don't always need the maximum brightness, I suggest adding a PWM power control unit. (Small adjustable PWM modules only cost a few dollars.) This will increase battery life also. If you are out all night, you don't want 30 minutes dazzling brightness, and then to be left in total darkness !
Just a thought: A de-soldering iron (hollow element and bit), run from a power controller to adjust the temperature, and feed the filament down the tube ?No, hang on, I've just re-invented the 3D printer.
As I see it, this device will be only appreciated by terrorists, criminals and nasty little vandals who enjoy causing trouble to other people.Please bear with me if I am missing the point, but why would any normal decent constructive person want to make a gadget that does nothing but destroy other gadgets ?
Please would you add clear titles to your pictures to show which is a fake card and which is real ? Many thanks !
Just for your interest: https://en.wikipedia.org/wiki/TheanineThe European Food Safety Authority EFSA advised negatively on health claims related to L-theanine and cognitive function, alleviation of psychological stress, maintenance of normal sleep, and reduction of menstrual discomfort.Therefore, health claims for L-theanine are prohibited in the European Union.
I'm a technician, therefore I'm required to sort out the engineer's glitches !

In step 1, you put "need noise pliers", but (with a little lubrication) could this be "needle nose pliers" ?
(Sorry but) another response to the "Always carry a knife" brigade !Try taking your knife on the airplane ! You will be spending time in lockup !Plane crash: you still have your paracord, now you can cut it, so this a useful Instructable !
It appears you have punctured the ball, so it will now quickly deflate.
Yes, that is the cheap Chinese copy of the "Unimat 1 Classic" lathe system (which I have)(and is about three times the price).
If you mean the little red and black thing, it looks like the motor unit from a Unimat Classic 1 modeller's lathe, with the accessory grinding attachment.
Li-Ion batteries are nominally marked as 3.6 or 3.7 V. When fully charged they show 4.1 to 4.2 V.When below (about) 3.3 V they should be recharged.(But can be charged anytime.)When disconnected from anything, they will normally hold their charge for months.(In a phone or anything with a clock function, they will slowly discharge even when it's switched off.)
One little bit of info might be useful to you - cacti & succculents like hot, dry bright conditions, but some mosses like shade & cool & damp, and will die in bright sunlight. (I speak from experience of moss gardening !)The fern (?) with tiny leaves used as a tree behind the bench works brilliantly - but I have never seen one like it. Do you happen to know what type it is ? Thanks.
I'm sure this Instructable is of great interest to car thieves. But it may tempt many foolish kids to become car thieves.Tell me Roman, how will you feel if this Instructable results in your car being stolen ?
A simple solution is a voltage converter, such ashttp://www.ebay.co.uk/itm/262372224750?_trksid=p20...which you can power from any (sufficiently powerful) battery within its input voltage range, and set to your required output voltage. I would suggest a 12V lead-acid battery. For a laptop you might need additional smoothing on the convertor output, a big and a small capacitor across the terminals. For a smaller laptop supply battery, use an RC car type or power tool battery of (at least) similar physical size to your laptop battery. Or you could just buy a spare laptop battery, charge it, and keep it with you. (Doh !-)(But you will need to switch off the laptop when changing it.)
