Intro TO FAB -Enclosure (W4)

For the enclosure assignment this week, I use a candy box with painting of Miyazaki Hayao animation. At first I want to build a noise generator with basic analog circuit which I seen before.

However, I find that the analog isn’t that easy to build. So I turn to build a arduino enclosure, because I can’t really spare more time from the final project. Then I remove the lid of the box.

 

 

I build a new lid with acrylic which is done by laser cutter.

Shockingly, I fail to wrap the wire well and it connect together form a short circuit through the metal box. This burn my battery holder, but lucky, this is the only lost to learn this lesson.

Intro TO FAB -REPEAT (W2)

This week, as the usual, I get some wood chunk and luckily found five pin pon  ball at the same time. Hence, I decide to build five paddle for it.

1.My raw material are not in a beautiful shape and surface that I have to do some pretreatment like cutting it into pieces with vertical angle. This will help with the afterward process,

2.Mark on the wood to unite the shape and size. Then use bandsaw to cut the material into target shape.

3.Use sanding machine to refine the edge and polish the surface to offer a smooth touch,

(now facing some issue of uploading pictures of process )

Take away:
1. It’s important to check if the shape of material upright
2. Jigs are so important to eliminate the mistake of human craft

Intro TO FAB -Flashlight (W1)

This is a simple normal flashlight with a weird but cute shape developed from its material which are all from shop and junk shelf. At first I pick up a L shape wood with one tiny hole one the extension L leg. Due to LED fits hole to this tiny hole, I decide make it the light source of this flash light. In the second phase, I drill one big hole and one small hole and for battery and wire. Unfortunately, I found that one battery cannot drive the LED I get from shop. To solve this problem, I found another wood piece from the junk and drill a hole to carry another battery. At last, I cut a piece of card board to cover some hole and wire as enclosure.

Finally. it works!!!

 

 

 

 

 

 

Take away,
1. never build a battery carrier by ourself
2. measurement and plan matters!
