A few weeks ago, we started a new project about making our own flashlight. First, we drew a sketch about what our flashlight looked like. Then after the rough draft, we had to use grid paper to make a sketch. We can make the flashlight anyway we wanted it. But, it need one led light, plus a switch, and a battery. Oh, and there’s one more thing, it had to be small enough to fit inside a box.

Drawing it to scale was really hard, but to make it more easy, we had this cheat-sheet thingy. First we had to find the pipes that we want to use for the flashlight. Then, we use the cheat-sheet to measure how big and then we sketch it. (You have to draw the sketch together.)

I had a cap, a straight pipe, an elbow pipe, and a plug. Making the cap, the straight pipe, and plug was easy. You had to use rulers, and some curves to make it. But, for the elbow pipe, it was really hard because there was one really giant curve and a very small curve. That’s why I had to sort of estimate the curves.

My drawing of the outside of the flashlight wasn’t the most  accurate, but I can work with it.

After drawing the outside of the flashlight, you have to draw the inside. You have to draw the led light, the switch, and the battery. You also have to draw the wires that connect to the three things. This part was really simple because I didn’t have to be too accurate.

This is my sketch for my flashlight.
