Art Therapy for Those with Limited Mobility

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.

Art is one of the fundamental ways humans express themselves and it occurs in every culture going back to the beginnings of humanity. Art therapy is a valued tool that bridges the disciplines of psychology and art and has been undertaken by Iraqi war veterans, victims of violence and other traumas.

But what about individuals whose limitations prevent them from holding a paint brush or manipulating clay? Haddon Pearson is a local creative type who is working with a child psychologist from the University of Chicago to develop systems that will enable people with limited mobility to make art. He will discuss some of the technologies and ideas that they are exploring to lower the bar for people with limited agency to express themselves.

The technology we’ll visit tonight is a Makeblock plotter that will potentially serve as the motion actuator for 2-d graphical output. The plotter is not feeling well at the moment. NERP aims to fix it, but first we need to understand the hardware and software that runs it. Andy Sowa will lead a live troubleshooting and learning session with the collaboration of the NERP Meetup.

NERP Tonite! Raspberry Pi Zero — $5

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.

Charles Kwiatkowski has worked in industry and academia since 1991. He enjoys learning and discussion on NERPish topics. If possible, he would live across the street from PS:One.

Tonight Charles will introduce us to the new Raspberry Pi Zero. The fun thing about following the small embedded market is the speed at which things change are changing. When the Basic Stamp was the only “accessible” microcontroller for hobbyists it cost $50. The Stamp was king of the hill for a decade. Things change faster now.

Comparisons between different embedded platforms is almost always apples and oranges, but price is the place people usually start. The RPi Zero’s retail price is $5. So there.

Beer Church: Sunday Oct 25th

We’ll meet in the lounge to have have our beer tasting: if you know an unusual or special beer that you’d love to taste but have been waiting for that moment, this is it. We’ll each sample what people (including you, if you want!) bring. While we’re tasting beers we’ll seek inspiration from them and each other and determine what recipe we’re looking to brew. Then we’ll head over to Brew & Grow and posibly Jewel to pick up some ingredients (they’re both right around the corner, how convenient). By 2:00 PM or so we’ll start boiling water and commencing the afternoon of brewing our own beer.

Around evening time after we finish up the brew and get everything cleaned, those who stayed ’til the end will get to taste the warm, sweet, and flavorful wort. Meanwhile, the yeast will be tasting it for the first time themselves. A few weeks after the brew, some of us will take the next steps of kegging the beer or putting it into a secondary fermenter.

This is a hands on class and collaborative project. If you have any questions we’ll do our best to answer them and any participant is totally welcome to take part in any of the steps of the brew: mashing, sparging, weighing ingredients, grinding grain, boiling, stirring, cleaning, racking, pitching yeast, setting up the bubble trap, and many other steps. If you’d rather just watch that’s fine too.

You must be 21 years of age to participate in Beer Church.

NERP TONITE! Enabling Universal Information Access: Libraries From Space

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.

outernet-logo

Syed Karim is the founder of Outernet, which is a satellite-based digital library service. Outernet takes content from the web and broadcasts it from six different geostationary satellites. The file delivery service is free to receive and most of Outernet’s code is open source. Plans to build a Raspberry Pi-based receiver can be found here.

“I’ll have a few slides, more for context, but would prefer if presentation was more of a conversation than a presentation. I’ll go over the general concept, content chain, and various types of receivers, including the newly designed Beaglebone Black derivative, which includes an on board DVB-S tuner, wifi module, and LiFePO4 charging circuit”

The following links may provide some context for the discussion.

NERP Tonite! Neural Interfaces for Advanced Prosthetics

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.

Tucker Tomlinson is a familiar face around the shops at Pumping Station One. He’s also a Postdoctoral Scholar in the Laboratory of Lee Miller in the Department of Physiology at Northwestern University Feinberg School of Medicine. Tucker’s work in the Limb Motor Control Lab* focuses on neural interfaces for advanced prosthetics.

Data acquisition systems used to record neuron activity typically work with lots of channels of analog-to-digital converters that measure tiny voltages and currents very fast. In Tucker’s words:

“I’ll be discussing the problem of recording directly from neurons in the brains of monkeys and humans. There will be a few slides and videos to help describe the basic science and technical challenges that we face when tackling this problem, but the session will be mostly informal discussion driven by whatever the audience finds interesting.”

* the phrase “motor control” means eye-hand-brain, not steppers

NERP Tonite! Roll your own firmware: The ESP-8266 Revisited

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.

The ESP8266 module has come up several times in discussions at NERP, and it keeps getting better. Tonight at NERP, Jay Hopkins will tell us about some of his recent findings as he revisits the esp8266. In Jay’s own words:

“The esp8266 is an ultra low cost module (sub $10) with an 80Mhz 32 bit processor, up to 4 MB flash memory, 100k of ram and 802.11 radio.   What sets the module apart from other ultra low cost modules is the inclusion of an 802.11 b/g/n radio and in firmware the IP stack for connectivity in the IoT (internet of things).

“At NERP we will be looking at the tools available to build firmware for the ‘8266.  Both microPython, lua and the arduino IDE are available for programming the ‘8266.”

Prototyping a Device to Measure Child Body Fat…

EDIT: PLEASE RSVP at Pumping Station One’s Meetup page  so we know how much pizza to get! /EDIT

Save the Date: August 17 @ 7pm in Pumping Station One’s Electronics lab:

Prototyping a Device to Measure Child Body Fat: What a Research Firm Learned When It Dipped Its Toe in the Maker Movement

NORC-logo

NORC at the University of Chicago serves the public interest and improves lives through objective social science research that supports informed decision making. Working extensively with the federal government, one of NORC’s key functions is to collect high-quality data.

Historically, NORC has collected data through surveys. In recent years, NORC has also begun to capture objective measurements of the “real world” using remote devices and sensors.

To deepen its capabilities, NORC identified a pilot project where it could learn more about the Maker Movement and hackerspaces. This project was inspired by a major federal research effort designed to help scientists understand the causes of a wide variety of childhood illnesses. For this project, NORC could not find an off-the-shelf body fat measurement device that met its needs. So they embarked on an effort to prototype their own device, working with a maker consultant who is an active member of the PS:One community.

Join us for an interactive talk to see the device they developed and share what they learned about the device and about partnering with makers to create a new hardware solution.
Speakers:

Brian Whiteley is an IT Director at NORC. Among his other responsibility, he currently leads NORC’s mobile and sensor based initiatives.
Randy Horton is Managing Principal of 94 Westbound Consulting and is a product and innovation consultant to NORC.
Randy Horton
Ed Bennett is a maker consultant and an active member of the PS:One community.

The NORC presentation on August 17th is on the PS:One calendar in a slot normally used by NERP. 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.

Radiationpalooza with Bionerd23, Ryan, and Elizabeth: Wednesday 8/12

Bionerd at ChernobylElizabeth and Ryan in Pripyat

Date: 8/12/15
Time: 7 – 10 PM
Location: Pumping Station: One, Lounge

bionerd23 has been a youtuber since 2007, but her science channel only became famous from 2012 on – that’s when she started visiting the radioactive exclusion zone of Chernobyl. Being on semester break in Chicago, this physics student will explain the basics of radiation and the devices that measure it to you – followed by insights into her trip to the Chernobyl zone with Ryan & Elizabeth. The three will give you personal insights on what it’s like to walk the abandoned, radioactive ghost town of Pripyat, including photos, video, and artifacts from the zone. They will give live demonstrations of radiation measuring equipment, including Geiger counters, quartz fiber and TLD dosimeters, NaI(Tl) scintillators, and gamma spectroscopy. They will also examine samples from Chernobyl under PS:One’s scanning electron microscope using secondary electron imaging and energy-dispersive x-ray (EDX) spectroscopy.

Bios:

bionerd23. Female homo sapiens sapiens (confirmed via PCR). Born in an ancient decade of mullet haired people. Resides around the radioactive wasteland of Chernobyl and frequently posts photon based imagery of her natural habitat on youtube. She recently appeared in the documentary movie “Uranium – Twisting the Dragon’s Tail” (aired on PBS on July 28 & 29 2015).

Ryan Pierce. Male homo sapiens sapiens (assumed but untested via PCR). PS:One member since 2012. Collects and repairs Geiger counters. Maintains PS:One’s SEM. Travelled to the Chernobyl Exclusion Zone in 2013 with someone he had never met, based on the popularity of her youtube channel. Currently serves as PS:One’s Secretary.

Elizabeth Koprucki. Female homo sapiens sapiens (PCR testing refused, leading Ryan to hypothesize she may have DNA of reptilian origin.) PS:One member since 2012. Former PS:One CNC Area Host. Currently employed as Assistant Director of Fab Lab and Design at Chicago Innovation Exchange, University of Chicago. Her first time leaving the country was her 2013 vacation to Chernobyl.

NERP tonite! Cypress Semiconductor’s PSOC IC’s

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.

Tonight at NERP, professional maker/hacker/DIY’er Bart Dring will introduce Cypress Semiconductor’s PSOC IC’s. PSOCs are odd beasts. They’ve been around since 2002, but there seems to be a growing interest in their peculiar mix of capabilities.

Cypress_April2015_pg4b

From the PSOC website http://www.cypress.com/products/programmable-system-chip-psoc

[Disclaimer: I have not used the PSOC product or its dev tools. -Ed]

“PSoC® is the world’s only programmable embedded System-on-Chip integrating an MCU core [ARM, of course], high-performance Programmable Analog Blocks, PLD-based Programmable Digital Blocks, Programmable Interconnect and Routing, and CapSense.  All new PSoC devices feature the industry standard ARM® Cortex® MCU cores.”

The development tools don’t sound to shabby either:

“PSoC Creator is a free Integrated Design Environment (IDE) which allows concurrent hardware and application firmware design… PSoC systems are designed using classic, familiar schematic capture supported by over 120 pre-verified, production-ready PSoC Components™.

Some of the config is done by drag-and-drop in a GUI.
