Mosaic Tile Stepping Stones

We’ll briefly touch on different forms of cement casting, molding, and draping’s, before spending the majority of class designing and building our mosaics. You’ll have several images available to base your mosaics on but please feel free to bring in any reference images or ideas you have! All materials are provided and we will have tons of tiles and stones available to put into the mosaics but feel free to bring any sturdy (stone or tile, maybe glass) objects that you think will go well in your mosaic and we’ll appraise to see if they’ll work out! The class will be 3 hours long, and at the end of it you’ll have between one and two finished mosaic tiles to take home!

🦖 Webcam Powered Dino Alert Electronics Project (CHM)

In this fun, beginner-friendly project, you’ll build a system that uses your laptop’s webcam to detect motion and trigger a hilarious **“Dino Alert!”** on screen. When movement is detected, a T-Rex appears, opens its mouth, waves its tiny arms, and warns everyone nearby with a roar. No prior experience is required. By the end, you’ll have a working Dino Alert system—and a solid foundation for building more advanced projects that combine software and electronics. **If you have a laptop, please bring it — but come anyway if you don’t!**

TELEGRAPH HILL & THE WATERFRONT

**This is a new walk. Though it is in familiar ground it is a new route.** **In the middle of our walk we expect to see on Telegraph Hill a giant plant with giant flowers that planted itself there and now in full bloom. It is called "Pride of Madeira" and it usually blooms in and around the month of April.** **The photo above here shows these flowers on Telegraph Hill about a year ago. Notice that the flowers are blue, Bees are attracted by the color blue more than any other.** **THE START OF OUR WALK** **We will gather at the far East end of the top of the Salesforce Terminal, next to the Beale Street Elevator, at 11:00 AM. The top has a beautiful park.** **I am charging $5 cash for this walk, but I don't collect the $5 until the middle of the walk. I only charge for half of my walks. Children are always free.** **At 11:10 AM we will start walking. Late attendees may find us walking around up there.** **To find me: I am 6 feet tall, wear a big blue & black hat and have a clipboard. One should bring water, and a sack lunch.** **Late attendees may find us walking around up there.** **We will officially end at Montgomery & Market Street where there is a BART Station, but I will be walking back to the Salesforce Terminal and others going there may join me.** **I advise taking public transportation & not driving to SF because both driving and parking there is usually bad.** **This walk is our first to honor a flower or plant. I will try to pick one to honor each month. My next one is the roses in the Berkeley Rose Garden. For the past two years we had a great time visiting that rose garden because they do something to get all of their roses to bloom at the same time which attracts big groups!** **The next Saturday, May 2nd, we will walk to the Berkeley Rose Garden, and there is a very good chance we will run into some Pride of Madeira.** **The Oakland Rose Garden is completely different because they let their roses bloom at their own speed resulting in fewer roses.** **On how to get around the Bay Area on public transportation see below:** **[Get directions & show routes - Computer - Google Maps Help](https://support.google.com/maps/answer/144339?co=GENIE.Platform%3DDesktop&hl=en)** **This walking group is for humans only. No dogs or other animals allowed.** **Photo at top is Telegraph Hill with April flowers.** **Some legal disclaimers: By joining us for any event you hereby RELEASE and DISCHARGE its organizers, hosts and participants from any and all liability, claims, demands or causes of action that you now have, or may have in the future, for injuries, damages, death and/or economic loss of any kind or nature, arising in whole or in part out of the activities, advice or information contained herein.

The Happy Little Arduino Spin Machine (CHM)

In this hands-on workshop, you’ll build your own **motor-powered spin art machine** using an Arduino—no experience required. At the heart of it all is a **DC motor**—your tiny but powerful artist. You’ll wire it up, control its speed, and watch as simple code transforms motion into mesmerizing patterns. Turn a knob, tweak the speed, and see how different rotations create completely unique designs. This isn’t about perfection—it’s about **controlled chaos**. A drop of paint, a burst of speed, and suddenly you’ve got something surprisingly beautiful. By the end, you’ll: * Understand the basics of controlling a motor with Arduino * Adjust speed in real time to shape your art * Create your own one-of-a-kind spin paintings * Walk away thinking, *“Okay… I can actually do electronics.”* Expect a little mess, a lot of laughs, and a machine that turns code into creativity. **If you have a laptop, please bring it — but come anyway if you don’t!**
