Finishing Touches I named everything that weren’t named. For example, the fastens and revolutes in assembly. Then I went back and tried to make some of the sketches defined. Thank you for reading these! This is the final devlog for the “reverse bike” project!

Finish (Almost) Almost everything is done, of course, I would love to go back and add more details to the bike but here is what is done: - The assembly is finished, meaning the movement of the bike can be shown by turning the handles and steering the pedals. - The seat is done, the back pipe is connected to the cushion. - Gear/Pedals done, its connected to the bottom of the bike, making pedals that have a maximum and minimum direction for when its steering. - Added back the fillets for the bike, making it cleaner. - Cleaned up the names, I added the names for every extrude, sketch, etc.

*Finished Handles and Started Assembly Currently, I finished the handles and the seat is still a work in progress as I figure out how it works and how I should start building it. However, I also started the assembly. Basically, when you turn the handle, it turns the back wheel as shown in the video. Next, I have to finish up the seat and make it adjustable. Also, the belt is for looks, it doesnt work, its like a visual representation of what is supposed to be there.

Handle Crank and Wheel Update It took a long time but after many iterations for the way the hand was going to spin the back wheel, I landed on the belt method. I wished I could have the belt with teeth and have gears instead. But this looks pretty good anyways. The next part I added was the pin that connects the wheels to the frame of the bike.

Wheel Strings Today, I worked on the strings for the wheels, I tried to make it so that the strings come from the rings, then go towards the middle of the inner wheels. I did this to both sides of the inner gear. Next up, the handle for the bike.

Clean-up This will be a really quick devlog but I cleaned up the names for all of the sketches, extrudes, etc, and simplfied some parts of the sketches, I decided that I will fillet the entire model at the very end to make everything more simple.

Backtracking, New Pipes, and Better Ideas I had to do a bunch of backtracking. I had to make the things that connect the wheels to the frame equal so that they could work, removed all of the fillets since they got in the way when I was fixing things. The main problem was how I was going to steer the wheels with the legs. Ideas: The first idea was using a rack and pinion. Connecting it by putting another on the other side of the gear. But I figured to go simple and turn the pedaling mechanism to its side. Currently, I made the two pipes, one for the front wheel and the other for the height of the bicycle seat. Another problem that I fixed is the size for the gear when you pedal, so I had to shorten the back length.

Basic Extrude Even though the side sketch is a giant mess, the extrude finally worked after it kept splitting into multiple parts. I refrenced actual bikes for my model. Next, I have to add the seat, handles, and leg steering.

Sketch Completed for the Side Previously, the bike had errors (represented by the blue lines). After some fixing, it looked ready for 3D modeling. I gathered information about what the bike’s body looked like at different angles. I tried to make the angles and lengths on the bike as clean as possible, rounding up or down. I also added more detail to the model.

Rough Sketch I got a image off of google and did a quick sketch based on the image directly. I tried to make the bike as accurate as I can. I made the width of the bike’s length 60-70 inches. Then I simplified the numbers, rounding them up or down.

this is a combination of two days. First was all of the sensors and basic code. I used: a DHT11 for the temperature and humidity, an RTC module for time and date (I didn’t use its temperature function), Arduino Nano ESP as the microcontroller, 0.96 OLED as the screen, a lot of wires, and used Arduino IDE for the code. After I got the screen to display the information (temperature, time, date, etc) I needed a way for the person to easily switch between the screens. Therefore, I used a potentiometer and the map function to switch between it. I used a potentiometer rather than a button and rotary encoder because it was simple to install. Then, I used cardboard for the housing. I cut where it needed to be bent and cutouts for the OLED screen and potentiometer knob. After that, I used a mini breadboard as the base for the potentiometer because it was sturdy for it to turn. Then, I added some decoration such as TV atennas.
