DIY for all occasions: an octopus robot, a full-height BB8 droid and a laser shotgun



    DIY is like a flight of fancy. It is not always possible to find a general idea in order to realize everything that is desired. On the Internet you can find many different blogs and channels of inventors of various ages. Sometimes they collect something toy, sometimes - the well-known devices themselves, thus saving a lot. Sometimes, ideas become so crazy that they quickly scatter across the Internet as an incredible incident or become a brilliant revelation for gourmet DIY gourmets, and then for ordinary people. So this collection, it does not have something thematically uniting, but it has a desire to find inspiration, both in the simplest things and in the crazy.

    DIY for beginners


    Robot octopus

    DIY masterpieces start small - the easiest way to start learning is with small and simple projects that even a student can do. Such projects are offered by a user from India , who shows in detail and step by step how to assemble an octopus robot at home. For him, you need to make a motor and craft 8 legs that help the robot move and maneuver under water.



    Flying bird on a thread.

    This device is very similar to a miniature version of an ornithopter. Its body can be made of knitting needles and cotton fabric, and in order to set it in motion you will need a small battery. To set the direction of movement, you just need to tie it on a thread to the ceiling. This small invention is perfect for atypical home decoration.



    A VR headset at your fingertips

    To make a VR headset you need any available convex lens. The simplest lens from a toy binocular or a small magnifying glass will do. The very body of such a headset can be made of foam. And for fastening its parts you will need an almighty tape.

    Toy robot from old CDs

    Now it’s quite difficult to find use for old and dusty CDs, but do not rush to eject them. They are perfect for homemade toys that you can give to children or frolic with them yourself. Two discs are perfect for the role of wheels, a motion sensor will allow the engine to start when you approach your hand. The concept and instructions are attached to the video.



    Toy boat

    A very simple instruction for a homemade boat with oars. She really swims and does it well. It consists of iron spokes, a pair of batteries and polystyrene. Oddly enough, the author makes the paddle blade out of the cover from Doshirak.



    Homemade machine

    If you have an old controlled machine lying around, then you can give its motor a second life. Using a two-channel receiver-transmitter, batteries, wire, popsicle sticks (and you always threw them away, right?) And springs, you can make a complete machine at home.



    Portable mini-fridge.

    I don’t always want to make some toys that later may not be needed at all, or which will have to be returned sooner or later. I would like something more serious and adult, for example, to make a portable mini-fridge for a jar or two of beer or cola. It can be placed next to the computer (which is very convenient) or carried with you in the car. To do this, you need a Peltier semiconductor cooler , a metal sheet, polystyrene foam and glue.

    Still Don't Love Your Neighbors? Then look at this guy ’s channel . It remains a mystery whether someone lives with him, and how he endures it. But you won’t even wish such a neighbor. And all because he collects 40W laser shotguns at home. The output of such a shotgun produces a beam of 40W, composed of 8 parallel beams of 5 W. The direction of the beams is adjusted by the lenses just like a shotgun throttle focuses a shot at a certain point. And he incinerates them everything that comes to his hand. You need to know in the face of the “ideal” neighbor.
