NERP Tonight — Report on OHS #5 in Rome -and- An FPGA Cape for the BBB

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’s NERP will be brought to you by Drew Fustini, PS:One’s maven of all things Open Source. Drew recently got an FPGA cape for the BeagleBone. The cape is called a LOGI (http://valentfx.com/logi-bone/). He’ll show us what he learned as he road-tested the development tools and the cape.

Also tonight NERP will get a brief overview of embedded computing topics from the 5th Open Hardware Summit (OHS), held this year in Rome, Italy. Drew went so we didn’t have to.

I’m out this week, so thanks much to Drew for hosting the meeting.

Bay View Boo!

I’ve lived in Bay View for the past 9 years and I have always loved trick-or-treating night here in the neighborhood (despite the fact that it isn’t actually on halloween!).  After I got some good photos of great costumes last year, I wanted to run a photo booth in front of the house on trick-or-treating night.  Add some procrastination, python and a couple of arduinos to a good idea and voila: Bay View Boo! was born!

1414276138

I started by building a shelf to hold the photo booth (and double for an extra shelf in the garage for the other 364 days of the year).  On the shelf, I set up an HDMI monitor, driven by my laptop and a logitech webcam for the camera.  The electronics were simple: I had an orange sanwa arcade button attached to an arduino to trigger the photo to be taken and another Arduino connected to a thermal printer from Adafruit to print out a link to the photo.  On the computer, i had a Processing sketch to drive the display, perform the countdown when the button was pressed and send the filename to the printer.  I also ran a little python app that pushed the images to Google Cloud Storage.  An AppEngine app displayed the photos.  I was in a bit of a rush to finish Saturday as I spent half the afternoon at Fantasticon and in my haste I forgot to add page navigation links to the front page.  Oops!  Ah well.  I had the site updated after i tore everything down for the night.  I had one trick or treater ask me if I had “like a raspberry pi in there or something” and I said, “Nope, but i have a couple of Arduinos!”.  “Cool”.  Cool, indeed.

None of the individual pieces of the project were very difficult and it all came together pretty nicely.  The most gratifying part of the night was hearing from people that they had heard from other people to come over and get their photos taken.  Word spreads quickly in Bay View!  I’ll be posting all the code to a github repo shortly and I’ll update this post with the link when I’ve done that.

For next year, I plan on making a couple of changes.  First, I want to have a nicer enclosure for the photo booth and something more permanent to mount the button and printer in than the white cardboard box i cut holes in with an XActo knife.  The second thing I want to do is make some interchangeable front pieces for the booth.  I could use this for lots of events and it would be great to be able to bolt on something that was more thematically appropriate than a painter’s drop cloth with holes cut in it and secured by shiny duct tape!  Ah well, it got the job done and after a while it was dark enough that no one could see my shoddy craftsmanship!  That brings me to my final change for next year: lighting. I had one 250W light ready for when it got dark and it basically sucked.  To everyone who showed up in awesome costumes once it was dark: I’m sorry.  I’ll have better lights next year so everyone can get a great looking photo, even if you don’t come out before the sun goes down!

Here are a few of my favorite photos from the booth.  I hope everyone who stopped by had a good time and enjoyed your photo!  I’ll see you again next year!  In the mantime, head over to Bay View Boo! to browse all the photos from the evening!

What’s new at your Hackspace?

If you’ve been following the mailing list then you’ll already know that the members have been busy tidying!

The once grotty toilet is now seeing better days, the leak will be repaired and the walls are being/been cleaned up and painted. If it hasn’t been done already, the floor will be, too!

We may still not have decent security cameras, but the screen to help monitor the Hackspace is in place and a web page is being developed to show on it the relevant camera(s) and any important information. People are welcome to chip in on developing what will be shown on it.

The roof should also have some extra sealant to prevent further leaks – this has came on in leaps and bounds over the past year and the main desk will be significantly dryer to say the least!

Speaking of desk, work has begun on a new one so that there’s more work space to sit at. The current desk, while useful in some regards just couldn’t house everyone.

Power tools have also been tidied and labelled in respective boxes.

So improvements abound! Thanks to everyone and members whom have volunteered in helping out so far!

Adding More Temp Sensors

Since my previous post I have added a couple additional temperature sensors to my piHouse project.  One is an outdoor temperature sensor that I previously programmed but never installed outside, and the other is a new sensor in my bedroom.  This involved some hardware planning and effort installing because I had to run a cable through the house and outside, but once I tested the new cable run, it was relatively simple to duplicate the software for the sensors I already had.

The part of this that took the most time was pulling the cable and then soldering the connections.  The biggest problem I have is placement of the outdoor sensor.  I am having issues with direct Sunlight.

Here are some highlights, you can find the whole story here.  This time I also include some examples of the commands I use on the raspberry pi to obtain the data.


When testing my hardware connections, I use this command to ask the pi to take a reading and then display the result to the command line:

house@raspberrypi ~ $ cat /sys/bus/w1/devices/28-00000512f401/w1_slave 2>&1

An etched copper presentation certificate

Five years ago, a dear friend designed the logo for my business, which I subsequently protected with a service mark. Although I paid her for her work I wanted to say thank you with more than just money.

Having an interest in decorative etching (among other steampunk pretensions), I decided to etch the service mark from the patent office into a 9 x 12 sheet of solid copper. After trying to transfer etch resist to the plate a number of ways (transparency and newsprint and a hot iron didn’t give sufficient quality), I finally hit on success after BrantH suggested I spray paint it, and remove the paint with the laser cutter. Here’s the process from start to end.

First, the plate was spray painted with gray primer. I originally tried Krylon, but I think it was ironically too durable, and resulted in a poor etch on the first attempt. I had to buff that out and start again. It also led to an interesting conversation at the hardware store, where I had to explain why I wanted a “less durable paint.”

Once the plate was painted, I laid out a border in Corel Draw, and imported the image downloaded from the USPTO. Then the design was cut from the paint. After some trial and error on smaller test pieces, I used speed 40%, and power 40% on the 50 watt laser cutter.

After the completion of the cut:

Once the cut was complete, the plate was bathed in a solution of 1x muriatic acid, 2x hydrogen peroxide. I eventually ended up making about three times the amount of solution shown here in order to get a stronger reaction.

This is after the etch was completed. You have to watch and determine when you have a sufficiently deep etch, it took me about 30 minutes.

The final proof the etch is deep enough is unfortunately only when the paint (acting as etch resist) is removed using acetone. If it’s not deep enough, get out the buffing wheel, and start over. This time however, it works!

Rubbing a bit of black enamel paint into the cut helps it stand out a bit better, particularly for the smaller text.

November 2014 Book Club

Thanks to everyone who made it to the warm, cosy, October book club meeting. Great to be back to the tea and biscuits model. Due to popular demand (and scheduling conflicts) we’ve decided to move the meetings to the second-Friday of every month. The next meeting is Friday, 14th November, at 19:30.

The book chosen is one that swept the awards this year, ‘Ancillary Justice’ by Ann Leckie.

The novel follows Breq — the sole survivor of a starship destroyed by treachery, and the vessel of that ship’s artificial consciousness — as she attempts to avenge herself on the ruler of her civilization.

New members, both tog-members and non-members, are welcome! Just bring a sacrificial snack ;) See you next month!

EL Wire Workshop

As halloween is drawing near, Tog will be holding an electro luminescent wire workshop this Saturday 18th October from 2pm until 5pm .  This is a great way to add a glowing element to any costume or accessory.

For €20 you will receive two metres of  precut el wire, colour can be picked and paid for on the day. Along with this there is the portable power pack, batteries included. The power back can be set to flash the el wire, turn on and off.  Guidance in soldering el wire and appending to garments on the day. The 2 meter lengths come presoldered so soldering is not neccessary unless you need to attach several wires together. For this reason it’s over 18s only.  Bring any clothing or wearables you may need to work with on the day. More el wire can be purchased if required. No pre booking required.

Dynamic Sculpture – Update 1

I am collaborating with the Betty Brinn Children’s museum to create something similar to this.

This sculpture has 844 balls hanging from strings wound around a pulley on a DC motor shaft. Ours will feature somewhere between 320 to 500 balls. I am currently working on a prototype to test and qualify different electronic and control platforms. It’s made out of 40mm x 40mm aluminum extrusion, laser cut wood motor mounts, 5V steppers, and ULN2003 based stepper drivers. I have been using an Arduino mega for now to test the motor and drivers.

The next step is to write software to create “voxels” with instructions akin to G-code. Additional software will be necessary to simulate the animation. G-code like instructions will be used by microcontrollers to control steppers in order to create an animation.

Solder Party

DSC_5907 copy

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!

It’s oveeeeer (the AGM)

Massive thanks to everyone who attended and raised points.

After a number of years sterling service, we’re sad to announce that Mick has stepped down as Director. Mick has been a LHS director since we were in the previous space and has been instrumental in putting us into profit and sorting out the finances. I’m extremely sorry to see him go and massively thank him for all the work done (insert mailing-list compatible standing ovation here).

Fresh from the success of the Cube, we’re pleased to announce that Matt Collins has stepped up and joined the directorship. He was nominated by a couple of people and confirmed unanimously.

Minutes and other paperwork to come shortly, but thanks again to everyone who’s been involved over the past year; old faces and new.

Fligg.

October 14 2014

Reminder: AGM

There will be an AGM tonight (Tuesday 14th October), the meeting is open to all (member and non-members alike) and is a chance to discuss issues around the space, review activities that have taken place over the year, and put forward suggestions about Hackspace. There will also be elections for the positions of Directors of the space.

If you have and points of order/interest that you would like raising add them below or to the mailing list and we can get a running order together.

Hope to see you there!
