How to Make a "Magic Brain" to Reinforce Content in the Classroom.
Introduction: How to Make a "Magic Brain" to Reinforce Content in the Classroom.
The objective of this project is to create a magical brain, a game in which there are cards with questions and answers that must be joined by making contact with the crocodile clips. As a sign that the chosen question was answered correctly, an LED light turns on.
This is an ideal project to learn a little about circuits in the classroom and reinforce the topics covered, as the cards are fully customizable and cards can be designed for many different topics. Now yes, let's start with the tutorial.
Supplies
• A piece of 60cm x 40cm x 0.5cm MDF (Medium Density Fibreboard)
• 4m of cable, including waste.
• 16 butterfly hooks
• One universal pliers and one side cutting pliers
• Acrylic of any color, in this case copper
• Electrical or electrical tape
• A hot glue gun
• Four pieces of wood
• A portalled
• An LED light
• A cap of a plastic bottle
• A battery holder
• Batteries for the battery holder
• A painter's tape or paper tape
• Hole punch
Step 1: Make the Marks for the Holes
The first step is to make the measurements and make a mark in the places where the hole will later be drilled. For that, at the top, you have to make a mark centered horizontally at 4cm from the top edge. In this mark will go the portal and its respective led. The next mark will be located 8cm from the top edge and 7cm from the side edge. This step should be repeated only 7cm from the other side edge. The cables that will be attached to the crocodile clips, the terminals, will pass through these holes. The next step is to draw a vertical line perpendicular to the top edge. This line should be located 8 cm from the lateral edge. Repeat this step only 8cm from the other side edge. On this line you have to mark a point 11cm from the top edge. From this point and always on the vertical line, continue measuring and marking 7 more points, one below the other, separated by 5cm. Follow this same procedure to mark another eight points on the other line.
Step 2: Make the Holes
It's time to make the holes. For that you have to measure, first, the portaled and choose the right wick. 997
After making this hole you have to continue with the other two below. For that, as with the previous hole, you have to choose a wick whose diameter is the same as that of the cable. After making the holes with the hole punch, you have to continue with the others. Simply choose a bit that is smaller than the diameter of the top of the butterfly hook and larger than the measurement of the two "legs" of the hook to finish all the holes. With this wick, the last 16 holes must be made, in which the butterfly hooks will go.
Step 3: Stick the Pieces of Wood in the Corners to Hold the Board
The next thing to do is, with the hot glue gun, join the pieces of wood with the 60cmx40cm wood, leaving a space of 1cm between the pieces of wood and the edges. Place the two largest ones in the upper corners and the two smaller ones in the lower corners.
Step 4: Connect the Aligator Clips
The wood part is ready, now we have to start with the circuit. For that you have to cut the cable so that it measures 55cm. Now, with the help of universal pliers and side cutters, you have to strip the two ends of the cable.
One of the two ends must be attached to the crocodile clip. To achieve this, use the pliers to cut the tip of one of the two plastic parts that serve to insulate the crocodile clip. This allows the cable to pass through, which is then hooked with the help of the clamp to one of the two holes. Once this is done, you can put the insulating plastic back in place. Now that the cable and the crocodile clip are already joined, you have to pass the part of the stripped cable (which does not have the crocodile clip attached) through one of the two holes below the one for the LED light. You have to pass the cable to the back of the wood to a point where the crocodile clip reaches the last row of holes but does not go too far. When you get to this point you have to make a knot (at the back) with the cable, so that it cannot reach more than the last one. This same procedure must be repeated passing the cable through the other hole. 259
