DIY for all occasions: a full-length robot octopus, a 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 desired. On the Internet you can find many different blogs and channels of inventors of different ages. Sometimes they collect something toy, sometimes - themselves known devices, thus considerably saving. Sometimes, ideas get so crazy that they quickly fly through the Internet as an incredible incident or become a brilliant revelation for the refined gourmands of DIY, and then for the average man. So this collection, it does not have something thematically unifying, but it has a desire to search for inspiration, both in the most simple things and in insane ones.

DIY for beginners

Octopus robot



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

Flying bird on a string



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







Improved VR Headset



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







Projector for smartphone



If you take two concave-convex lenses and foam, you get a projector for a smartphone. All ingenious is simple.







Toy robot from old CDs



It is already quite difficult to find the use of old and dusty CDs, but do not rush to throw them out. They are perfect for homemade toys that you can give to children or frolic with them yourself. Two discs are great for the role of wheels, a motion sensor will allow the engine to wind up when your hand approaches. Concept and instruction are attached to the video.







Toy boat



Very simple instructions for homemade boats with oars. She really swims and does it quite well. It consists of iron spokes, a pair of batteries and foam. Blade paddle author, oddly enough, makes the cover of Doshirak.







Homemade machine



If you have an old controlled machine lying around, then you can give its motor a second life. With the help of a two-channel receiver-transmitter, batteries, wire, chopsticks from the popsicle (and you always threw them away, huh?) And springs, you can make a full-fledged machine at home.







Portable mini fridge



You do not always want to make some kind of toys that may then not be needed at all or that you will have to give away sooner or later. I want something more serious and adult, for example, to make a portable mini-fridge for a can of other beer or cola. It can be put next to the computer (which is very convenient) or carry with you in the car. To do this, you need a semiconductor cooler Peltier , sheet metal, foam and glue.

DIY for advanced

Humanoid robot InMoov



If you suddenly wanted to personally assemble a humanoid robot on your home 3D-printer, then you will be helped by many wonderful people who spread the open source code of a humanoid robot. If the fantasy beats the fountain, then it is not at all necessary to follow the instructions thoroughly. You can experiment, complement and improve your humanoid robot. A user from the MKme Lab channel decided to build a Humanoid Robot InMoov and step by step to lay out the build process. While on its channel you can find a very detailed description of the assembly of the arm and head of the robot.

BB8 droid in full growth



I'd like to have a cute Star Wars robot, but is the Sphero BB-8 Droid too expensive? So it can be collected independently, and in full size. It can be controlled from any smartphone, it “talks” well and the cost of it is only 120 dollars. To collect it will need a variety of household materials and Arduino. A 17-year-old Filipino will tell you how to do this.







Laser shotgun



Still not love your neighbors? Then watch this guy 's channel. It remains a mystery whether someone lives with him, and how he tolerates it. But such a neighbor, even the enemy does not want. And all because he collects 40W laser shotguns at home. At the output of such a shotgun, a beam of 40W is obtained, composed of 8 parallel beams of 5 W each. The direction of the beams is adjusted by the lenses in the same way as the choke of the shotgun focuses the shot at a certain point. And he incinerates them all that comes to hand. You need to know in the face of the "ideal" neighbor.
