Fortress Mode: Arduino Motion Gates (CHM)
Tue, Jul 7, 2:00 AMStep into engineer mode and build your own automatic security gate using an Arduino, a motion sensor, and a servo motor! In this hands-on class, you’ll create a mini “fortress gate” that springs open whenever someone approaches. Along the way, you’ll learn: * How motion sensors detect movement * How servo motors create controlled motion * Basic Arduino programming and wiring * How real-world smart security systems work By the end of the class, you’ll have a working motion-activated gate and the skills to customize it with lights, alarms, or secret fortress upgrades. No experience needed — just bring your curiosity and prepare to defend the kingdom. 🏰🤖 **If you have a laptop, please bring it — but come anyway if you don’t!**

Mosaic Cement Project
Fri, Jul 3, 1:30 AMYOU MUST RSVP/PURCHASE TICKETS THROUGH THE ACE MAKERSPACE WEBSITE: [www.acemakerspace.org/calendar](https://www.acemakerspace.org/calendar/) In this class we’ll be creating tiled mosaics in a sand base and then coating them in cement to create sturdy finished mosaic 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! If you need a scholarship for this class, please **[submit this request form.](https://docs.google.com/forms/d/e/1FAIpQLSfyuFC_Cv4EdCcQUFFkSVSb4NHuhisZ1z6DJI_i-BWz8wznBw/viewform)** You may be notified as little as 24 hours before the event.

Roaming Telegraph Hill and the Waterfront
Fri, Jul 10, 10:00 PMIt's two years now since I moved to Telegraph Hill. Of course I think it's one of the finest neighbourhoods in the city, but I have resisted roaming around it more than other areas. We haven't done it for a while though, so I thought it was time to visit again. This roam will take us to the foot of the Coit Tower, and across the north eastern waterfront. There will be plenty of climbing, though this time we will skip the bulk of the Greenwich and Filbert steps. We will meet on the stairs in front of Saints Peter and Paul Church on Filbert St by Washington Square. *Bringing water, snacks, and layers for all the microclimates is the way to go.* *These roams are offered by donation. They are one way I am able to pay my rent in San Francisco.* *Punctuality is always appreciated. Please send a message on the app if you are running a little late - direct messages are best, rather than a comment on the event. I can usually respond to messages before we get underway, but then I put my phone away other than to take pictures.* *I know Meetup is notorious for no-shows and late changes of rsvp. I am not as strict as other organisers (we do talk to each other!), but since generally up to half the people who sign up don't show up, my tolerance for repeated flakiness is limited. It is especially unfair to people on the wait list who would like to attend.*
