Ball Hinge In Tinkercad

  I learned to make ball hinges while I was designing a hand for my Servo Robotic Hand project. In this project, I will first make a Ball Hinge and explain how we can use it to make anything hinged with a hands-on on a Bat model that we will import or copy from the gallery. Things We Need Computer Internet Tinkercad account  Creating Ball Hinge Use solid box from Basic Shape menu and change its dimensions to Length = 15mm, Width= 15mm and Heignt= 10mm. Use hole box(transparent), change its dimensions to Length = 5mm, Width= 15mm and Heignt= 20mm. Place this box into the solid box(Pic Align them so that the sold box forms a "C" shape after grouping both of them. Group both the boxes by selecting both the boxes and group them(Ctrl + G). Now drag a sold sphere to the workplane. From Shape Menu change it to Hole and its Steps to 24(this will give it a smooth surface). The diameter of this sphere will be 9mm(or L=9, W=9, H=9). Align this hole sphere in the sold C shaped box and gr...

Circuits Using Modeling Clay

Making modeling clay structures is fun, but making them with light-up eyes and moving parts is even more fun. Clay modeling is one of the favorite activities of kids because kids like being messy. I thought it would be icing on the cake if they will see glowing light, running motor and sound of a buzzer on Clay. This hands-on learning can be easily done at home by using few materials. Clay has a playful nature, so kids can explore Electronic Circuits in a playful way. They will learn about Closed Circuit, Open Circuit, and Short Circuit. This hands on learning can be done by kids above 4 years. You can initiate or encourage curiosity just by asking this question : Do you know you can make creatures or things using modeling Clay that can light up, move and make a sound? Watch their ZEAL for the learning !! Things We Need A power source with a current value of 5 volts. I have used a battery of 9 Volts. Two wire leads with alligator clips on each end. Modeling Clay. Some finely grinded sa...

Fun With Soldering

Whether you’re building a robot or working with Arduino, form "hands-on" electronics to prototyping of a project idea, knowing how to solder will come in handy. soldering is an essential skill to be learned if someone is really into electronics and making. Learning to solder is relatively straightforward but it takes a little bit of practice to become a master. In this project, I'll share how my kids enjoy learning and mastering this important skill. Things We Need You will need: A soldering Kit Perdboards Some electronic components like LEDS, resistors, etc Power Supply Soldering:  Soldering is a process in which two or more items are joined together by melting solder around the connections providing reasonably permanent but reversible connections. Solder Wire:  (Pic 2) It is a metal alloy which is usually made up of a Tin/Copper alloy(60% tin, 40% lead). It comes in both lead and lead-free variations with diameters of .032″ and .062″ being the most common. Due to enviro...

Puppet Bird

This storyteller Bird is my son's favorite prop when we roleplay or have a storytelling session. This bird is very easy to make and certainly adds a smile to the face and makes storytelling even more interesting.  Things We Need To make this bird we need: A Square Piece of paper ( 21cm by 21cm) Coloring pens Pencil Scissors  Folding the Bird First, lay the paper on a flat surface, so that one of its corners is facing you. Now, fold it along the diagonal. Crease the folded edge will fingernails and then unfold the paper. Next, fold the two side corners to the creased diagonal and then fold the paper in half along the same creased diagonal at the center. Measure 14 cm from the bottom and put a mark with a pencil. Then connect this mark with the side corner with dotted lines. Fold along the dotted lines and continue folding and wrapping this extruded part until a small triangular flap remains. Tuck this flap in the pocket to lock it properly. This will be the beak of the bird . C...
