International Tabletop Day 2014

International tabletop day

International Tabletop Day

Want to hang out with a group of fun geeky people at a Hackerspace and play some awesome games? How about homemade snacks and homebrew beer? Still not awesome enough for you? Well, how about we hack an Xbox Kinect and scan you, then 3D print a custom game piece with your face on it, or make custom game counters on a laser cutter?

Come on by Pumping Station: One, Chicago’s biggest Hackerspace, on April 5th and have some fun and maybe even learn a few skills! Bring your favorite games, or if you want some supreme geeky-points, bring a game you designed and play-test it with us [we can even discuss how to spruce-up your game with lasercut or 3D printed pieces, hint-hint]!

This event is public, so bring your family, friends, or just awesome gamers you know and wanna hang out with! If you want to take part in making the 3D printed game pieces, or laser cutting custom counters, we do ask for a minimum of $1 suggested donation to cover materials. If you want to see this stuff continue into the future, please donate more! Proceeds will go to Pumping Station: One’s donation box.

Bike Night – Fixing bikes in February

Hello everyone!  It’s been cold.  It’s been snowy.  But some of you people are still riding your bicycles.  Being cold and snowy doesn’t stop the need for maintenance.  Every other week is Bike Night at PS:1, and we’ve got our doors open for you.

Sometimes we bring in things to show off.  Sometimes we teach.  Usually we work on interesting bike projects.  (Learning how to wrap bars, building a bike from the frame up, etc) Last night was playing bike doctor more than “here’s fun stuff to work on.”  We had two patients last night.

Patient #1 received a new chain and sprockets to replace a stretched set.  And, the rider discovered the magic of clipless pedals last year, so replaced his platforms with some SPD pedals.

Patient #2 had some cheesy short term replacement pedals replaced with some very nice platforms, and had it’s headset rebuilt.

Does your bike need a tuneup?  Do you have questions about picking a new bike this spring?  Do you want to learn a new bicycle related skill?  Come visit us, we’ll be gathering in the shop March 5 at 7PM.

NERP: Spark Core – Warm and Fuzzy Computing

Monday Feb 17th at 7pm Jeff Camealy will present his talk “How to control your electric blanket with a Spark Core”. He describes his use case: “The Spark Core is a small Arduino compatible chip with built in WiFi and Cloud connectivity. This functionally can be used to easily create a device that can be controlled remotely. We’ll see how we can use the Spark Core Cloud to create an iPhone App to direct your blanket from the comfort of your .. blanket.”

nerp_spark-core-2

Lest Jeff sell himself short, it should be said that he’s spotted a technology that’s powerful and significant, but also somewhat strange. Until now the Arduino programming environment hasn’t often been associated with cloud computing. It’s not clear to me whether this is a niche application, or the start of a trend in small embedded controllers. Not surprisingly, the ARM architecture continues to insinuate itself into every corner of embedded control. The Spark Core uses an STMicroelectronics STM32F103 ARM M3 running at 72 MHz. The WiFi is provided by a TI SimpleLink CC3000 module. If you don’t like the cloud you can use the Spark Core as an ordinary USB-programmed controller that has WiFi. The spark.io site contains these [edited] points to help in understanding what the Spark Core does:

The Spark Core is a tiny, open source Wi-Fi development board that makes it easy to create Internet connected hardware. The Core is all you need to get started; power it over USB and in minutes you’ll be controlling LEDs, switches and motors and collecting data from sensors over the Internet!

There’s no need to ever plug the Core into your computer; you can write code in our web IDE and download it wirelessly to the Core. The Core uses Wiring, the same programming language that Arduino uses. Plus, with an accessory called the Shield Shield, you can connect the Core to a standard Arduino shield.

The Cloud is the mother ship that the Spark Core connects to when it comes online. Once the Core is paired with the Cloud, it becomes accessible from anywhere in the world through our open but secure REST API. Cloud service comes free for life with the Core. [excerpts from https://www.spark.io/]

Excitement!

Thanks to Drew Fustini and the kind folks at element14, we’ll have a drawing for a fully assembled Gertboard. “Gertboard is the ideal add-on for Raspberry Pi. Designed by Gert van Loo, it is a flexible experimenter board that plugs directly into your Raspberry Pi, and out into the physical world…” [element14]

CNC Build Club Double Feature – 1/23/2014

fsl3d

 

In addition to having Alden Hart talk about the TinyG and motion control in general, Andrew Boggeri of Full Spectrum Laser is going to show off their new sub $2000 SLA resin 3D printer. This is the printer that is currently crushing the goal on Kickstarter.

Stop by and check out the machine and see some of the prints.  Resin printers are a little messy to move around so we probably won’t see it print, but plenty of samples will be shown.  He will be able to demo the drawing speed, software and cloud interface.

The CNC Club is free and open to members and non members.  If you want to attend, please RSVP on Meetup.

CNC Build Club – TAZ 3 Unboxing

TAZ 3

 

Thursday (1/9/2014) night at 7pm we will have an unboxing party for Pumping Station One’s new 3D printer – the Lulzbot Taz 3! The Taz 3 prints larger and faster and in more materials than the other printers we have at the space. Come check out the mysterious BOX, see the printer set up, and maybe we’ll even get to Hello Squirreled.

Also, Ryan Pierce will be presenting “The Hard Knocks School of CNC Milling” covering how he made every mistake possible, and how you can avoid making them yourselves! This will include a lot of useful, practical tips, and a demo of the method he is using, showing the entire tool chain process, to route precisely aligned pockets for his and Elizabeth’s “CNC Steampunk Harp” project

CNC Build Club with Alden Hart: 1/23/2014

AldenHart

Alden Hart, the creator of TinyG and the grblShield will be in town later this month and will give a talk at the 1/23/2014 CNC Build Club @7:00pm.  The meeting is open to members and non-members.  If you want to attend, please RSVP via Meetup.

The grblShield is a basic stepper motor driver Arduino Uno Shield.  It is part of the standard parts list for the Shapeoko and there are thousands of these in the field. It can also act as a shield for the Arduino Due and run a special version of TinyG firmware.

The TinyG project is a multi-axis motion control system. It is designed for CNC applications and other applications that require highly precise motion control. TinyG is meant to be a complete embedded solution for small/medium motor control. Here are some of the main features of the v8 hardware.

  • Integrated motion control system with embedded microcontroller (Atmel ATxmega192)
  • 4 stepper motor drivers (TI DRV8818) integrated on a ~4 inch square board
  • Stepper drivers handle 2.5 amps per winding which will handle most motors up thru NEMA23 and some NEMA34 motors
  • Accepts Gcode from USB port and interprets it locally on the board
  • 6-axis control (XYZ + ABC rotary axes) maps to any 4 motors
  • Constant jerk acceleration planning (3rd order S curves) for smooth and fast motion transitions
  • Very smooth step pulse generation using phase-optimized fractional-step DDA running at 50 Khz with very low jitter
  • Networkable via SPI to support off-board devices and for networking multiple boards into multi-axis systems
  • Microstepping up to 1/8 (optimized DDA makes this smoother than many 1/16 implementations)

Writing the Night Away with Writer Zen Garden and NaNoWriMo!

20131113 Pic 1November is National Novel Writing Month, or NaNoWriMo.  The objective is to write 50,000 words or more during the month.

One of the ways to do that is to attend a Write-In, an event where participants support each other, engage in word wars, and commiserate on the vicissitudes of the writing life – and otherwise abuse their vocabulary.

Tonight’s Write-In in the lounge was no exception.  We came, we wrote, and we played Go to unwind.  Writers worked on short story compilations, manga, speeches, and novels.  If you’ve always wondered what it’s like to write a novel, then by all means join us!  The next PS:One Write-Ins are Wednesday 11/20 and Wednesday 11/27 from 7:00 to 9:00 P.M. in the Lounge.

The Writer Zen Garden hosts a number of events at PS:One, including our popular Prompt Circle, Artist Way Clusters, and Plotting Workshops.  Check us out on Meetup or stop by an event.

Write on!

CNC Build Club – 4 Axis Milling

4th-axis_large

 

(picture from CNCCookbook blog)

This week we are going to play with the rotary axis on the little CNC mill.  We are going to assemble it and calibrate it.  We will use a demo of DeskProto to run a job on it.  We will of course start with the CNC Ninja Squirrel, then try some other projects.  It you have something cool to try, bring a file in STL format and a round piece of material to mill it out of.
