We’ll be brewing up a beer this Sunday the 4th of January at 12:00 Noon. As per usual, we’ll hold a beer tasting first. If you can, please bring something interesting, unusual, homemade – if not, you’re just as welcome, we have never not had enough beer for the tasting.
Once we’re done tasting we’ll select a brewmaster (the person in charge of the brew – as much as anyone is in charge of the brew), pick a recipe, and head around the corner to Brew & Grow to get the ingredients. By 1:30 or 2:00 we’ll be brewing and we will usually be done brewing by 7.
The event is very hands on – anyone who attends can help out at any stage. You will get to try the beer when it’s finished (this can take a few weeks), and help with the later steps if you like including transferring into secondary fermentation, kegging, and bottling.
Potential recipes for this Sunday:
* Winter lager
* … you tell me?
You must be 21 or older to attend Beer Church. We encourage you to RSVP on Meetup, but this isn’t required.
The class is not only a great way for people to get a feel for the space and our community, but it is also a requirement for joining as you must take the class before joining or within 3 months after joining.

Here are the class notes – please feel free to read beforehand (Note: these notes are not a good substitute for class attendance).
Saturday’s Solder Party was fantastic! We got all the circuit boards trimmed and tinned.
I’m thinking of doing this again for future projects (and I’m looking for circuit knit ideas and collaborators!). A few things I learned from Saturday’s event that will be helpful:
- Removing the scrap wire beforehand would be helpful and/or we need better diagonal cutters in the lab.
- A piece of cardboard behind the board keeps flux off the table, and provides a guide for blocking the knit.
- Boards to practice on would be helpful. Also, wetting down the boards will prevent scorch marks.
- We have replacement soldering iron tips in the lab.
- Bacon really is the best pizza topping and La Villa is the Pizza In A Bag place.
We didn’t get everything done, so I’m hanging out in the lab this week to finish. (Jay Hopkins apparently has become addicted to soldering knit circuit boards, and has been working on them even when I’m not around! Thanks, Jay!)
Everett took great pictures. I’ve posted a few here but you can find the entire album on our Meet Up page. Please visit, and tag yourselves!
If you’d like to get into beer brewing or are already a brewer, or just like & appreciate beer, then come down to the space at noon on Sunday. We’ll be having a beer tasting and brew day. We’ll likely taste a brew we made recently and make something new. Justin will be the brewmaster. Of course, you must be at least 21. See you Sunday!
You can RSVP on meetup if you like but it’s not required.
We’ll be having a beer tasting and brew day on 9/20 (Saturday) at 12:00PM noon. We normally brew on Sundays, but we’re mixing it up this time. We’re looking to make an Octoberfest Lager or a Märzen, but it’s really up to whatever the people who are going to participate in the brew want to do. Our temperature control system Chillmon is working, so any fermentation temperature is possible.
The brew is a very hands on workshop, even first timers can try their hand at various parts of the brewing process including recipe development, prep, mashing, grain grinding, mashing, sparging, boiling, pitching, kegging, and setting up our in-house bar. We go from malt, hops and yeast infusions all the way to serving out of our chilled tower tap system. If you just want to watch and listen, that’s fine too. Any idea or person is welcome.
We’ll be tapping our Rosemary Stout for the first time this Saturday. If you’d like to share anything please bring it (craft brew, homebrew, whichever)! We love to talk about your homebrew or the interesting beer you made or found that you want to experience with other beer aficionados. You must be 21 years old to attend Beer Church.
You can RSVP on our Meetup group.
Probably the most neglected, yet most useful, tool for circuit designers is SPICE. SPICE gives you the luxury of simulating circuits to predict the results prior to building a physical circuit. Being able to change resistor values or transistor configurations within a couple mouse clicks and a few keyboard presses, is a very powerful and time/money saving feature. As such, it is also very useful in troubleshooting previously built circuits to find solutions to lingering design problems.
SPICE (Simulation Program with Integrated Circuit Emphasis) is open-source software released under the “BSD license”. Several companies produce their own version of SPICE, such as TINA from DesignSoft or PSpice from Cadence. However, the fastest and most user friendly implementation is LTspice. LTspice is provided by Linear Technology and is completely free to use without restriction. It is the same software that is used internally at Linear Tech to develop and test their line of analog/linear semiconductor ICs. It was written by Mike Engelhardt, who periodically goes on tour teaching classes and answering detailed questions for his own software.
I’ll be holding a class to introduce the basics of using LTspice. LTspice was originally written for Windows and was recently ported to Mac OS X. The Windows version is capable of being run on Linux through Wine, but it obviously doesn’t run as well as on a native Windows machine. I’ll be teaching with the Windows version, since I am the most familiar with it. The Mac version has a slightly different user interface, but it shouldn’t be too difficult to keep up. Here are the topics I’ll be covering:
- Placing & Wiring Up Components
- The Most Basic Simulation: DC Operating Point
- Labels and “Net” Names
- Finding Frequency Response: AC Sweep
- Using the Plot Window
- The Real Deal: Time-Domain Simulation (Transient Analysis)
- Piece-Wise Linear (PWL) Sources
- Using SPICE “Directives”
- Working with Semiconductors
- Linear Tech’s IC Models and Test Jigs
- Importing 3rd Party Models & Sub-circuits
- Who: Anyone who wants to learn LTspice (Open to the Public). Some circuit knowledge is required.
- When: Sunday, September 28th – 2:00pm to 4:00pm
- Where: 3519 N. Elston – 2nd Floor in the Electronics Lab
- Cost: FREE
At 12:30pm on 8/24 we’ll start with a beer tasting (bring your favorite homebrew or craft brew), decide a beer recipe, go shopping for the ingredients, and then do a hands-on brew session with the following steps:
1) malt grinding
7) pitching yeast
8) setting the fermenter temperature and starting the fermentation.
We’ll probably also keg or bottle one of our previous brews.
This event is open to anyone ages 21 and over. No need to RSVP, see you on Sunday!
Sunday, August 3, 1-5pm

Hackers frequently need to solve geometric problems for their projects. Whether it’s cutting acrylic on a laser cutter, slicing wood on a table saw, planning the route of a robotic arm on a new 3D printer, or analyzing a polygon mesh in a Python script, a working knowledge of geometry can save time, frustration, and material costs.
This isn’t the geometry you learned in high school, though. This is a crash course in the basic notions of linear algebra, perhaps the most useful branch of mathematics there is.
This course is geared towards demonstrating practical concepts and applications that can be put to use immediately in your own projects. To avoid bogging down the class with tedious details, we will use our computers to perform the calculations for us, allowing us to focus on the big picture and core ideas of each technique we cover.
The only prerequisite for the course is a solid understanding of high school algebra. Exposure to vectors and matrices would be helpful, but not required. There will be a review session before the class officially begins for anyone who wants to brush up on the basics.
Topics for the class:
- A Review of Coordinates, Vectors, Matrices
- Examples of Linear and Affine transformations
- Linearity, Bases, and Where Matrices Come From?
- Square Matrices, Determinants, and Inverses
- Application: Solving Systems of Linear Equations with Gaussian Elimination
- Dot Products, Angles, and Lengths
- Cross Products, the Plane Equation, the Normal to a Plane
- Application: the Line-Plane Intersection Test
- Triangles and Baricentric Coordinates
- Application: the Line-Triangle Intersection Test
- This event is open to the public
- Prerequisite: High school algebra, some light exposure to vectors and matrices
- When: Sunday July 20th at 5pm, review session starts at 4:30pm.
- Where: 3519 N. Elston – 2nd Floor in the Electronics Lab
- Cost: Free
