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.
