My Challenge to Make a Marble Run Machine - The Ball Rising Function

It was a hot day today. I didn't feel like doing anything, but I tried to be motivated to design a marble run machine. Luckily, I could make a little progress. The rough idea of one of three systems of raising balls became specific, and I drew it on 3D software. After I finished drawing, I experimented with the system to make sure it worked well.

Luckily, there are plenty of timber off-cuts. I made some holes using the CNC router and tested how a ball rotates. I always realize that even though I thought I considered a mechanism well, something that I didn't expect happens. Therefore, the experiment is crucial.

I always knew that I wanted to make something that nobody had thought of. However, it's arduous unless I'm a genius. I try to not use the same design as others made, yet after all, what I thought of were not exactly the same, but very close. Honestly, I wanted to make something more unique, maybe next time.

The other two ball-rising functions' designs have been decided. One is the chain, and the other is a cam function. I have already made sure these two could work well. Therefore, this disc function was the last one. If I could complete it, the mechanism of moving balls from the bottom to the top is getting closer to accomplish.

As you can imagine, rolling balls down to the lower level is easy. Pulling balls to a higher level is a bit tough. If I could complete these three functions, I would be relieved a little.

The details of these functions will be released when my first marble run machine is completed. Until then, the details of my marble run machine are secret. There is no reason to keep them secret, but I believe it's much more fun to see the marble run machine without advanced information when it's completed.

Tomorrow and the day after tomorrow's highest temperature will be hotter than my body temperature. I don't know how much progress I am able to make. Hopefully, I would like to make some gear tomorrow.

 

If Japan Wins

There was a football match between Germany and Japan last night. I was convinced that the German team was powerful, and I didn't expect Japan to win. The match was held at midnight in Australia, so I didn't watch the live broadcast and went to bed.

However, I saw the news that Japan won the much this morning. It was surprising. The Japanese team defeated the German team.
It wasn't only me. Many Japanese believed that Japan would lose.

Then, there were some exciting things that happened.
Before the match began, many Japanese declared on Twitter, "If Japan wins, I will do XXX."
One guy said, " If Japan wins, I will ride from Yamaguchi to Tokyo by bicycle." The distance between Yamaguchi and Tokyo is about 1,000km. He regrets what he just tweeted.
The other guy said he would change his hairstyle to a strange design. This isn't a bad declaration. He can cut his hair short if he doesn't want to keep it.

Here is the terrible one. There were guys who said that they would run in a town naked. The same declarations were seen here and there. They probably chose the most embarrassing thing and hesitated to act because they didn't think Japan would win at all.

Well, what are they going to do?
