Running on ground

Motion not too smooth

Completion date: April 30, 2020

Observations
1. Motor to propeller is 24=40=40:24:16. So propeller is running 1.5 times faster than the motor (24/16=1.5)
2. Motor to wheels is 24=40=40:24. Same speed.
3. The belt can be used to pass on the same speed from one gear to another, and these gears would move in the same direction. The belt can also be used to pass the motion over a longer distance.
4. The axle can be used to pass on the same speed and same direction of the gear on the same axle. Also, the axle can be used to displace the motion to another gear on the same axle.
5. One gear can invoke motions on multiple gears.
6. Gear’s direction can change from left/right motion to become front/back motion by using a direction-changing gear. While this is happening, the difference in gear sizes can speed up (or slow down) the next set of gear motions.

Mahjong table frame

Purpose: To make a collapsible frame for a portable table. Completion date: 2025-01-12 The main purpose of the frame: Provide raised step (~0.5cm height) for aligning the tiles in a straight line A place to put turned-over tiles along the frame Raised step design to prevent the tiles from falling off the table Portable table: 34” x 34” Mahjong mat: 31” x 31” Materials: Cardboard Adhesive wallpaper Double-sided tape 4 x L-shape brackets Paper Nano tape 8 x snap button bottom part Old ziploc bag Non-slip mat backing Steps Cut 8 strips of cardboard. 4 pieces: 1” x 34” 4 pieces: 0.75” x 34” Fit set of four strips (0.75”) on the table with the mat. Mark and cut two ends 45 degrees. Fit the strips around the mat snug with its inner edge against the mat's edge. To check if snug: push the frame strips and see if it moves the mat. If yes, good. If not, try to reduce the slack gap in between the frame and the mat rim (could swap the strips to find best fit). Mark the...

Python script - pop-up reminder based on data from Excel

Completion date: December 17, 2018 Changes to the script (Dec 14 2018): 1. Used Date format to compare dates. 2. Show message for update AR if the date is overdue and due today. Changes to the script (Dec 17 2018): 1. Corrected the ws.max_row+1 to ws.max_row. 2. Changed to loop from bottom up (so the the newest records gets checked first) =========== The script =========== #! python3 -- Modified on Dec 17 2018 import openpyxl import tkinter.messagebox from datetime import date import os #Get the workbook, worksheet file = "AR.xlsx" wb = openpyxl.load_workbook(file) ws = wb['Sheet1'] #Iterate through the rows of column "Next update on" = Column D = 4, from bottom up (the newest record to oldest) for i in range(ws.max_row, 2, -1): next_update_datetime = ws.cell(row=i, column=4).value if (next_update_datetime is n...

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.
