Wear-A-Circuit Workshop on Sunday

2016-10-27-3-patches-dark-13-32-00

2016-10-27-patches-on-13-35-11

Circuit Patches are wearable circuit boards made from knitted yarn and wire. I’m doing a workshop Sunday using these. Check it out!

I use a knitting machine to make the patches. Add snap buttons and  attach the circuits to anything you like.

Rapid prototyping for Wearables!

I made these patches for my workshop this Sunday, 3-5pm. Participants will receive a 3″ x 5.5″ knitted proto-boards in black, pink, or teal. Solder LEDs and a battery on it, and you can add lights to your clothes, just in time for Halloween.

 

Of course, there’s lots of things beyond LEDs you could add– I’m hoping to do workshops for interactive circuits using the knitted protoboards in the future.

I’ve made a number of circuits with this method so far, often in black. For this workshop, we’re adding  fun colors: circuit-board-teal and… pink! I  couldn’t resist adding 10mm gumdrop LEDs to the pink protoboard pictured above.

We’ll have some of those jumbo LEDs for the workshop, but also smaller ones in blue, yellow, red, white. I’ve even got some color-change and flicker LEDs.

Power is supplied by a hidden battery pack.

If you’d like to participate, please RSVP. Hope to see you Sunday! (Bring a shirt or a hat or a bag so you can add snaps to mount your circuit on it.)

NERP^2 = Hardware: From Concept to Retail && PiAQ: Indoor Air Quality Sensor

PLEASE NOTE: NERP WILL GET UNDER WAY AT EXACTLY 7PM ON MONDAY!

Next Monday at NERP we’ll have a double feature. We’ll hear part 2, of Ste and Nicks’s story of adventure in bringing a successful consumer product to market. Part 1 was about technology, and part 2 is about the _business_ side of bootstrapping HD Retrovision (http://hdretrovision.com). Also on Monday, Dave Conroy will tell us about the PiAQ Open Source Indoor Air Quality Sensor for the Raspberry Pi (http://piaq.io).

About HD Retrovision:
Nick and Ste have been friends since 1999 and both share a passion for playing the (now retro) video game systems that they grew up on. Since then they’ve both studied Electrical Engineering at University, and are now business partners in a company called HD Retrovision that is dedicated to improving the modern day experience with retro consoles while making it accessible to as many people as possible. In this presentation, Ste and Nick will walk you through the ups, downs, and lessons learned while taking a college project and turning it into a profitable company. This talk will cover how they took the idea for HD Retrovision’s Genesis and SNES cables out of the lab, got it funded, and eventually mass-produced overseas.

NERP Tonite! Google Summer of Code students build BeagleBoard.org projects

Tonight at NERP, Drew Fustini will be sharing highlights from his presentation at Maker Faire New York 2016.

Drew explains How Open Source software and Open Source Hardware intersected in several BeagleBoard based projects done for the Google Summer of Code.  “Google Summer of Code is a global program that offers students stipends to write code for open source projects.”  These students’ projects demonstrate the synergy of devices and the code that makes them what they are.

NERP Tonite! Improving the Retro Gaming Experience

Ste Kulov is Lead Design Engineer at HD Retrovision. Ste (known in NBA Jam as STE) was born and raised in the suburbs of Chicago and spent most of his childhood with his hands glued to a SNES controller. Like so many life-long nerds, Ste went to school for electrical engineering and became an expert at working with circuits. His passion for working on really cool engineering projects is second only to his obsession with video games. Ste conceived the original idea for HD Retrovision in his engineering design class to solve the world’s most pressing problem: allowing gamers to play their old systems on TV’s that don’t have the right inputs. [NERP Note: HD Retrovision cables are analog circuit devices. The HD Retrovision circuit board is molded into the cable.]

PS:One knows Ste for being a really good teacher. We wish he could find time to do more analog and fpga circuit classes (hint, hint).

A vital aspect of manufacturing is testing and quality control. Someone has to do it, and they need test instruments, test fixtures, custom software, and detailed written test requirements and procedures. Ste had to design a turnkey QC system for use by his contract manufacturer. The HD retrovision circuit itself is all analog, but the QC system is FPGA based. At NERP tonite, Ste will explain how you QC a cable on the other side of the world.

100th NERP Tonite! Embedded GUIs part 2 of 2: Qt

For the 100th NERP Meetup (Yea!), we’ll have the second of a two-part discussion of embedded GUIs on small Linux devices. Qt is much more than a GUI library. Tonight Ron Olson will share some wisdom on the Qt application framework. Ron tells me that Qt promises a lot, and it delivers. Sounds good to me!

Ron says “I figured the main thrust of the talk would be Qt, how it works, its two main parts (C++, QML), and how it works with the BBB as well as a Qt project controlling an Arduino, all with an eye towards demonstrating the QML, and lightly, the C++ connection.”

After graduating from NYU’s film school, Ron took full advantage of his film and theatre background by becoming a software developer. For 24 years, Ron has been one of the developers that companies go to when they want to make their customers lives worse; he helped write the system to show commercials at MTV, worked on cancelled projects at an animation studio that went out of business, pioneered allowing you to lose your retirement savings on the web at Bankers Trust, came up with new ways to target ads to you at DoubleClick, did his part in the financial crisis at Goldman Sachs, and lately has been writing software to help your attorney remember when your trial date is.
Mostly in C++ and Java.

Elliott Rouse is the Director of the Neurobionics Lab in the Center for Bionic Medicine at the Rehabilitation Institute of Chicago. The vision of his group is to discover the fundamental science that underlies human joint dynamics during locomotion and incorporate these discoveries in novel, effective wearable robotic technologies.

At NERP on Monday, Elliott will show us some fun stuff from his lab including a new generation of his group’s robotic knee. We’ll see that a robotic knee is much more than a motorized linkage, although it is that, too.

Abstract: The Neurobionics Lab is interested in understanding neural control of movement from the lens of mechanical descriptions. The intent is to use these discoveries to design and control a new class of assistive technologies. These technologies would be capable of not only replicating the natural biological torques and speeds, but also the underlying stiffness properties. However, since many of the stiffness properties are unknown, the Neurobionics Lab also seeks to supplement this philosophy with the design and control of technologies that cleverly implement or leverage mechanics. The purpose of this talk will be to discuss ongoing research and a few specific technologies that are currently being developed in the group. The presentation will focus on two technologies, the actuation of wearable robots with balloons, and a novel low cost, lightweight robotic knee prosthesis that is powered by drone technology.

Bio: Elliott Rouse is the Director of the Neurobionics Lab in the Center for Bionic Medicine at the Rehabilitation Institute of Chicago and is an Assistant Professor in the Department of Physical Medicine & Rehabilitation, as well as the Departments of Mechanical and Biomedical Engineering at Northwestern University. The vision of his group is to discover the fundamental science that underlies human joint dynamics during locomotion and incorporate these discoveries in novel, effective wearable robotic technologies. The Neurobionics Lab uses technical tools from mechanical and biomedical engineering applied to the complex challenges of human augmentation, physical medicine, rehabilitation, and neuroscience. Elliott received the BS degree in mechanical engineering from The Ohio State University in 2007, and the MS and PhD degrees in biomedical engineering from Northwestern University in 2009 and 2012, respectively. Subsequently, he joined the Massachusetts Institute of Technology as a Postdoctoral Fellow, working with the Biomechatronics Group in the MIT Media Lab until 2014. Elliott and his research have been featured at TED, on the Discovery Channel, CNN, National Public Radio, Wired Magazine UK, Business Insider, and Odyssey Magazine.

NERP Tonite! Raspberry Pi with 3D Resin Printing, Big and Small

A few days ago, Andrew arranged the donation of a ZBuilder ulTra 3d resin printer to PS:One. Since Andrew has been working on small a table-top 3-d resin printer using the Raspberry Pi and nanoDLP, it seemed natural to try the nanoDLP controller on the big machine.

As far as we know this retrofit is a new use case for the RPi.

3dprinter-04

3dprinter-02

I found the build platform motor leads and Andrew connected them to the nanoDLP system. With a bit of fiddling, the platform started to move as expected. Meanwhile Andrew had a good start on getting the projector to run, and before we were really ready, the essential system components seemed to work. (In the pic below, you can see the the Raspberry Pi logo displaying on the build platform.)

3dprinter-03

It’s already clear that there are lots of details that need addressing, but those problems seem surmountable.

NERP Tonite! Report from the 2016 Embedded Linux Conference and IoT Summit

NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.

April 4th through 6th, PS:One’s Drew Fustini attended the Open Internet of Things and Embedded Linux Conference (OpenIoT & ELC 2016) in San Diego. Since embedded Linux powers pretty much all the OS-capable single board computers and computer modules that we see at NERP, we’re eager to hear Drew’s insights on how current advancements and innovation in embedded Linux and hardware will help us at NERP make cool stuff that nobody’s thought of yet.

Event: Confectionery Combat! Chocolate VS Shelly and Gerald

shelly-and-gerald-vs-chocolate-smaller

 

What:
Confectionery Combat! Chocolate VS Shelly and Gerald:

When:
Friday February 12, 6:30-8:30 pm

 

We will start with a discussion on the evil ways of this culinary foe and tactics to successfully wage war against it.

We will be making truffles, roasting nuts, coating lots of things with chocolate, and “practicing” our feeble double boiler tempering skills.  Practice is the word! Just as in war there is no guarantee of success but at least in this we will have chocolate.

This event is open to PS:One members and their guests who want to watch, sample, and participate as the space allows. (There will probably be a cap at 10 people in that small kitchen) If you know you are coming give us a holler on the member group here so we can prepare excess supplies and plan our battle strategy.  The cost is free but donations to fund our efforts will encourage more such campaigns.
