STORY 5: "Soldering must be fun"

Hello.

Hi, Come in.

Mr. Fusamura, would you show me your electronic handicraft kit now?

Hikaru, you are very excited about this, aren't you?

Of course. Look, I've carried my favorite tool "HAKKO DASH" with me.

I would like you to use my soldering iron "HAKKO RED".

No, thank you. I prefer my DASH iron. Mr. Fusamura, let's start soldering now.

OK. Just a moment. Now where did I put it? It must be around here somewhere.
I found it. Here you are.

What is it?

"Dice".

Electronic "Dice" Kit Seven LEDs flash like points of dice.

"Dice". Is this dice?

Yes. If it is shaken, the LEDs flash for a while and then stop suddenly. When the flashing stops, the LEDs look like points of dice. It can also make a sound.

It seems somewhat difficult.

Printed circuit board

Such an electronic handicraft kit comes with a printed circuit board. So, it can be easily assembled by inserting components and soldering them.

Really? Well, I'll try to make it using my favorite "HAKKO DASH" right away. Oops, I forgot I must ensure ventilation before I start soldering. Then, I put inflammable objects aside and read through the instruction manual.
