Robot beetle: how to make a homemade cockroach from a capacitor and a vibration motor

If you know how to solder, this little project will take you about 20 minutes. A homemade robot cockroach uses a vibration motor as its head, the motor is powered by a capacitor, which is also the abdomen of the insect, the specification indicates the following parameters of the capacitor: 2.8V 5F, you can buy one for 100-150 rubles.

You can use diodes or resistors as legs and antennae. All these components are soldered together on one small circuit board, which is also the thorax of the insect.

Since the microrobot uses a supercapacitor as its power source, we will need two AA batteries for power (as shown in the video above).

Finishing touches

Thread the clasp into the leather base, calculating in advance what position the brooch will be in. We glue the prepared cardboard to the fabric, then to the leather. All this is sewn along the edge so that the felt and the base with the fastener are well connected. We bend the bug's legs and you're done - the brooch can be used for its intended purpose.

Brooch making process

Let us examine in detail a master class on making a beetle brooch from beads. You need to start from the back of the bug. To do this, an oval stone is sewn onto felt, then pearls are sewn tightly to it. Black crystal 1, which is larger, is sewn into the center of the pearl. 2 green lenses in the form of a beetle's eye are sewn on the sides of the black one. Small black Small black lenses are glued to the stone. A kind of crystal rim is made around the entire circumference of the stone. 4 large black lenses are glued to the back, between which we glue small green beads. We border the pearl with sand-colored beads, and glue it between the eyes and head.

The felt is cut to the shape of a beaded beetle brooch so that it is not visible. 6 blanks for the paws are made from wire. It is better to choose copper wire, it will look beautiful. We cut off pieces of wire and bend them with pliers in the form of real paws. The paws are evenly sewn to the felt body. We make an abdomen out of cardboard that will hide our paws. Glue on top of the abdomen. Take a small piece of black fabric into which a brooch pin is attached. Everything is carefully glued to the cardboard belly of the beetle. After drying, the excess fabric is cut off, and its edge is trimmed with black beads. For bead beetle wings, make a stencil on paper or cardboard, and then transfer it to 2 pieces of felt. We trim the edges of the wings drawn on felt with brown trim.

We sew a row of the outer oval of the wing with green beads, then attach a bicone, the second row is also sewn with green beads, bordering the bicone with them. The rest of the space is also lined with gold-colored timber. We do the same for the second wing.

We attach rings to one sharp side of each wing. On the back side of the wing we glue cardboard molds and pieces of leather. The edge of the leather is trimmed with the same cuts as on top. Next to the beetle's eyes we attach the wings using rings. Once this is done, the beetle is completely ready. The wings can be opened and closed. This completely changes the appearance of the brooch. Just look at the photo of a beaded beetle and you will understand that your time will not be wasted.
