Scooter as a trolley

Trial date: January 30, 2019

My Taobao stuffs have arrived! Exciting day! The parcel weighted at 7.41 kg and it's height was up to my waist.

It worked! However, the clips are not very secure if I tried to lift the scooter from the bottom with my feet (e.g. reorienting to the opposite direction).

Replaying:

I rode down my scooter downhill with the net and clips on the scooter handle. 35x35cm net just won't fit in my bag.

I installed the plastic folder file as planned before, put the parcel on the net and wrapped it with a 2-meter long elastic band. One hook on the net and the other hook secured at the steering wheel.

When pushed the scooter uphill, I even put my bag on the handle, it was a breeze moving the bundles!

After thought: I don't carry big baggage like this often and I doubt if I ever would got to improve this. However, if I were to improve this, it would be allowing the rider to be on the scooter as well. I drew some ideas, but I am skeptical if they would work. Oh well, keep thinking...

I bought a shoe rack along with many other things from taobao (online shopping) yesterday night. The parcel is going to arrive at a SF express shop 10 minutes walking downhill from home.

I really have been thinking for a while, the scooter is so convenient one can go grocery shopping with it! I was expecting to find a basket or some sort that could attach to scooter. Well, I couldn't. Not even from the famous Taobao where I can sometimes see rare inventions. Most are just bicycle baskets! With scooter if the weight is too much at the front, the scooter would trip forward easily if it is not ridden (just pushing).

I don't know if it would work when I get the parcel next week, but here is what I put together:
1. Take a 35cm x 35cm metal net (I have at home)
2. Take a legal size file folder. Trim the width down to 22cm. Fold it in half.
3. Take 4 x binder clips. Clip the scooter platform, the metal net and the file folder together.
4. Elastic rope with hooks at both ends. (I haven't bought it yet). This rope is to prevent the baggage from fall off the platform.

I am excited to try it out next week when my parcel comes. More photos to follow!

Gear investigation: Klutz Lego Blender

Completion Date: May 31, 2020 After I finished with Banbao gears collection, I search on web for other building instructions. I came across the Klutz Lego and saw the picture that I just built from looking at it. It was quite easy and fast, however, I would like to convert it to vertical winding, but I don’t know how yet. So here is the original one. Gear ratio is 40:8=40:24 = (40/8)*(40/24)=8.3 times faster then the hand-winding motion.
