Who doesn’t like flower decorations? But how do you make them look realistic without an expertise in origami? Well thanx to happypuppytruffles you can now make super realistic paper flowers in many variations! Just use thin paper or even tissue paper and you could make gorgeous flower decorations super easy! We haven’t tried it, but are willing to bet that you could even use toilet paper to achieve the same gorgeous result! Preferably unused toilet paper though
Many people may feel that drawing 3D objects is too hard. But if you want to draw an object in 3D there is a very simple trick. In this particular video from Handimania a hand is used, but this technique can be used for most objects. This is one of those tricks that is easy to learn for simple objects but can also be used to draw highly complex geometry in 3D by simple practice. So why wait? Pick up a pencil, a couple of markers and start experimenting today!
This is truly an revolutionary video! Did you know that objects can be levitated and moved around in mid air, using only sound? In this incredible video from Yoichi Ochiai (YouTube Channel 落合陽一) we see the first successful attempts to acoustically levitate small objects like styrofoam balls, water droplets, matches and even metallic nuts! Perhaps one day we can even levitate big objects like skateboards or cars? What would you like to levitate with this technology?
Whenever big industry needs to paint a metallic object, they tend to prefer powder coating. Powder coating is the process of using a static charge to electrically attract paint particles onto an objects surface evenly and reach tight spaces. It is particularly valuable in mass manufacturing since it is dependable and makes painting easy to automate with robots. But since the process is a bit more complex then just using a spray can, most hobbyist never powder coat any of their parts. But if you really want your parts to have that high production quality look, you should definitely watch this video from NYC CNC that demonstrates how you can use technique at home!
From MinutePhysics comes this excellent video that explains how different kinds of light sources work. This is very useful for anyone who needs to decide which types to use in their project, as well as anyone who is generally interested in how they work. This is of course just a very basic and metaphorical video but there is a lot of more information to find out there. None the less it is a very interesting and easily understandable summary.
