$$ A = \pi r^2 $$

to write equations like the one above use LaTeX formatting (LaTeX cheat sheet) with double dollar signs ($$) as delimiters. Thus the above equation would be:

$$ A = \pi r^2 $$

I made a clock run by a Raspberry Pi
It gets the current time over Wi-Fi and can print the arc length of the clock hands.

I cut the frame out of wood on the laser cutter (The frame is approximately 13.25cm in diameter), I used 60 LEDs from the 144 LED per meter strip.

I am using a Raspberry Pi Pico W to program the LEDs, the code is a modified version of the code on Doc’s GitHub. It gets the current time over Wi-Fi and tracks the time with an internal clock, sets the LEDs to simulate the clock’s hands, and prints the arc length for the seconds, minutes, and hours hands.

The arc length formula is: degrees from zero of the clock hand/360*2*pi*r(radius)

Doc’s original code is bad because it is specifically made for the clock he made, where there is only 59 LEDs instead of 60, so it has to jump around and skip seconds to stay accurate, also, his LED strip is counter-clockwise, so you have to figure out how to reverse his code.

I first started off making a galaxy drawing on procreate and then laser printed it on a wooden plank and colored it with colored pencils. I then realized it looked like “Starry Night”.

I made this yarn kite because I needed something to do and it was easy. I did it a long time ago at art camp so I knew how. You can make some pretty intricate ones, this one is simple though.

In Mackerspace, I have been experimenting with the minimal necessities and best ways to create a self-sustaining terrarium. I am using three different types of moss and experimenting with drainage. The six combinations I am trying are:

• Java moss+ABG
• Java moss+ABG+false bottom
• Polytrichales+ABG
• Polytrichales+ABG+false bottom
• Pin cushion moss+ABG
• Pin cushion moss+ABG+false bottom

The moss I am using takes a long time to die even if it isn’t properly sustained so after almost one month I have no results.

One day I got super bored and didn’t have a project to do. After spending nearly the entire time trying to find what to do, I eventually found two pencils and a random ball of light blue yarn and decided to use them to knit. I decided not to do a particular design, but it will be finished when the yarn runs out. This project is very relaxing and fun to do. It provides a nice break from stressful stuff. So far, I think I’m halfway through the yarn or close to halfway. By doing this project I learned that it’s really easy to find the basic materials for knitting and starting.

This week in maker’s space I worked on planning a seat upgrade for my car, which is a Fiat 500. The new seat is made in Italy and the company is Italian. It is a bucket seat and I want to upgrade to it because it’s cooler and safer. I made sure to measure the dimensions and the height of the seat compared to the old seat. I also investigated the bolt sizes to make sure they fit the brackets. I figured out which tools I would need. Most of the bolts are 16 mm and 10 mm. I have all of the information I need to order the seat when I have the money to buy it.

I made some wooden replicas of some monuments from around the world.

I used some scraps from the scraps pile and hot glued things together.

I made the pyramids of Giza, the Chicago bean the Kilianan nuclear powerplant, and the Gagarin monument. Even the Obelisk of Piazza Navona.
