Computer Engineering

As part of the [Arduino Days 2026](https://days.arduino.cc/about) world-wide celebration, we will be meeting in-person and online to talk about all things related to the Arduino platform. For the best possible experience, please attend in person and bring a laptop with a USB port, and your project or project ideas. We will have several Arduino computers available to borrow and experiment with during the meeting, including the new [Arduino Uno Q](https://www.arduino.cc/product-uno-q). Beginners and Experts are welcome to attend and participate! A rough agenda for the meeting shall be: \* **Workshop and Live Demo:** A short interactive hands-on introduction to Arduino. For online participants, we'll use [Tinkercad](https://www.tinkercad.com/). For in-person participants, we'll have a few Arduinos available to experiment with. Depending on the experience and interest of the participants, we might skip this introduction. \* **Ask the Arduino Expert:** Get Arduino project help from the experts. Got a problem with a project you're working on, or need advice on getting started? Get in-person and online help to get you going! We'll go around the room and see what each person needs help with. \* **Show-and-Tell:** Got an Arduino or other digital electronics project to share? Talk about it informally and share what you've learned! It can be as simple as a Blink project or as complex as an Edge AI application. You do not need to be an expert in the subject matter. \* **Open Day:** Work on your projects during the meeting. You can listen, share, or get going on your projects, whatever you decide! Bring your soldering iron and tools. \* **Build a Project Team**: Looking for project help on a longer-term basis? Share your project and find willing participants to help you finish it!

This event is managed by Nature Nerds Austin -- https://www.meetup.com/nature-nerds-of-austin/ This is the monthly design status and update meeting. Participation is both in person and online. The meeting will be held at a private makerspace, Diogenes. It is located in the same building as the adult club Colette Austin. The door is at the left end of the building, Suite C. Go to the back of the first floor workspace and head upstairs. If you have questions please feel free to submit them in the comments below or send them to me directly. Zoom meeting details will be posted about a half hour before the meeting begins. HABEX - High Altitude Balloon Experiments The reference to experiments is two-fold. The first is in regard to the actual balloon construction and flight processes. The second is a reference to the payload and what it does during the flight (e.g. images, environmental measurements, etc.). To be clear, there will be two design processes going on in parallel, the balloon proper and the payload. This initial flight is really focusing on the balloon to get that process pinned down and clearly defined. The initial payload should be simple (e.g. digital camera taking pictures). One of the primary design considerations will be the use of CanSat techniques in the design and construction process. We may need to build a technology demonstrator for this (i.e. dummy payload) before the actual flight process. CanSat -- https://en.wikipedia.org/wiki/CanSat Design Process: Design/Buy > Assemble > Test > Loop (Will it fly?) > Flight Plan Meeting Sequence: Pilot - Initial meeting (possibly two) to gauge interest and get first round of participants. Design - Group responsible for the first four stages of the Design Process. - Multiple meetings. Pre-Flight - Review process to date and verify readiness - Set the date of launch - Possibly two meetings Launch - Two teams (Launch and Recovery) Clean up - Launch team cleans up launch site and transitions to tracking and telemetry Recovery - Recovery team (possibly several groups) chases the balloon and tries to stay ahead of it. Post-Flight - Review, analysis, and release of flight report (including experimental results if any). Flight Plan: * Pre-Flight * Schedule * Assembly * Launch * Tracking * Recovery * Review/Release Results Constraints: * COVID 19 * Budget * Resources/Tools/Facilities * Legal (e.g. FAA rules about weight and number of modules) * People * Transportation

Bring a whiteboard or a laptop or a piece of paper. We will be solving 1 easy and 1 medium problem on LeetCode. We have no rules for being late or leaving early, you can be late and start from the second problem or do the first one and leave. The main idea is to work together on it, share thoughts and discuss a solution. For those who don't like the time pressure during the session, I will be posting problems in the comments for the session 1 day in advance.

***Isha Kriya*** is a simple yet potent meditation created by Sadhguru. "Isha" means that which is the source of creation. "Kriya" means an inward action towards that. Isha Kriya, ***a free guided meditation***, takes only 12-18 minutes and is an easy to learn process that you can do at home, work, or wherever you are. This meditation can bring clarity, health, and joy. **Ages**: 12+ (those 12-17 to be accompanied by a parent/guardian) Location:Holiday Inn Express & Suites Austin NW, 10711 Research Blvd, Austin, TX, US, 78759 Date and Time:Saturday, March 28, 2026 at 1:00 PM - 2:00 PM CDT RSVP:https://online.innerengineering.com/en/event-details/22916 Contact Details: Austin@ishausa.org 512-655-9589

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
