Organizer for charging cables

Completion date: 15 February 2019

I wanted a charging cables organizer long ago. I have been dropping my cables on the floor after using them, and searching them on the floor every night.

I bought the 9-pack wire organizer $20 at Japan Home. I still bought it even the organizers are not ideal (the side coverage is too short), because I couldn’t stand the thought of buying from Taobao again for such a trivial accessory.

Originally I only planned for wood block with the wire organizers only, however the wire organizers turned out to be a total failure, so I had to add piece of plastic to complete the project.

What I did:

1. Cut a piece of wood (just the width of a ruler)

2. Stuck the wire organizers onto the wood

3. Cut out 8x12cm plastic from file folder. Folded like so.

4. Fixed the plastic on the wood so the markings can be made

5. Punched 4mm hole on the markings

6. Cut a vertical straight line all the way to the first folded line

7. Drilled a special hole for countersunk/flat head screws (used wood drill bit 8mm, used HSS drill bit 8mm to drill 3mm deep, used 1/8 drill bit dead center all the way)

8. Here is my little table. Turned it over and Drilled 2 pilot holes to the table, and installed the organizer.

9. The 8x12cm plastic was too short but still did the job. I had to pre-thread all these cables. Next time I have to make it longer so that the cables have more room to go through.

Gear investigation: Banbao Lego pirate ship on a swing

Completion date: May 14, 2020 1. Gear ratio is 16:24. The top spinning is at 0.66x of motor. I thought that the black gear connection just pass on same speed, but by experiment, the speed gears has the same effect just like when they are in contact. 2. By connecting the gears via the connection links, the gears turn in the same direction. 3. By connecting the gears via the connection links, it solves the distance problem between the two gears with a simple solution. Without the connection links, many gears would be needed to get to the top. 4. I think this pirate ship is a tricky one, because one would have to tune the spinning speed to match the latency of the ship for the swinging motion to be smooth left-right-left-right. How to Give the push at the right time? Also, the motor and the gears can get damaged when the motion is always interrupted.

Star cushion

Completion date: Jun 12 2020 Steps 1. Trace the star shape onto the fabric. Double over the fabric. Apply pins to secure the edges. Cut out. 2. Install a platform on the sewing machine. 3. Whenever I need to turn the fabric I place the needle down on the fabric before turning the fabric. Sew until I get a 15 cm opening. 4. Flip the fabric inside out and put the foam filling inside the star cushion. Bind off the opening by hand sewing. My daughter requested for a star cushion. I recycled filling of a foam-type cushion into this one. This was the first time I used a platform. The table was not long enough but I put something underneath to support the platform. She was pleased with it though it wasn’t pink as she originally requested. Below in the picture was her little hand!
