Haymarket
737 W Randolph St Chicago, IL

25 Members Attending

This group is based upon the idea that you are interested in hanging out and discussing hardware. Please bring a piece of hardware to show off or talk about. Are you interested in hardware, but you haven’t built anything yet? Show off software you have built! Or come prepared to talk about the projects you want to build. There are no organized talk…

Hope to see you there!

Hologram.io: Open-Sourcing Our Hardware

Ben Strahan of Hologram.io writes about why development hardware should be open source:

Open-Sourcing Our Hardware

It’s a simple premise – black boxes stifle innovation while open systems encourage exploration. Black Boxes and IP have their place as an essential tool in our economy; but in an industry like IoT where rapid innovation is needed, we need to push for open development tools as the building blocks that lead to innovative end-products for industry and consumers.

Going forward Hologram will open-source all hardware we develop for the developer community, including dependent firmware, through OSHWA. We see this as a mandatory step we need to take to help move IoT forward, to lower the barriers to entry, and to spur innovation in a rapidly evolving ecosystem.

The hardware design files for the new Hologram Nova module are available on GitHub:

Hardware Happy Hour (3H) Chicago this Tuesday

Hardware Happy Hour (3H) Chicago for June 2017

Hardware Happy Hour (3H) Chicago was excellent this past Tuesday at Saint Lou’s!

Sebastian Gajate was in town all the way from Argentina and presented The Amp Hour host Chris Gammell with his own fútbol jersey!

Thanks to Andrew Sowa bringing his camera and taking the above shot and many more wonderful photosBart Dring brought his latest CNC build: a drawing robot based on Line-us.

Here the draw bot in action:

Brian Rutkowski’s impressive LED spinner project was a crowd pleaser!

 

 

 

Watch more of the dazzling LEDs in this video:

The adorable Simula robot by Jamie Laing was another favorite:

Simula made several new friends:

We were excited to get a look at the purple PCB inside:

Andrew Sowa showed the results of his technique in KiCad for converting photos into PCB artwork

We were excited to meet Jose Ignacio Romero who had designed the Low Power Continuity Tester for the One Square Inch contest on Hackaday.io last year.  He brought many projects to share including this color memory LCD board:

We’ll learn about some of the building blocks of creating a synthesizer using the 4046 VCO and the classic 40106 CMOS ICs. The 4046 is a well documented and powerful IC that can be turned into a modular synth voice with just a few added components. Participants will learn to solder together their own prototyping PCB, build a circuit on a breadboard from a schematic, experiment with sensors, and learn the basics about how to produce custom circuit boards using design software like Kicad and Fritzing. No experience is necessary, but basic electronic knowledge or a strong interest in synths will be helpful.

Creating the Benchoff Nickel

Screenshot from 2017-03-23 13-54-53.png

Andrew Sowa writes about the PCB he designed in KiCad to surprise Brian Benchoff last weekend at the Hackaday Unconference in Chicago:

Creating the Benchoff Nickel

I thought of making the Benchoff nickel after I saw Brian’s Hackaday,io profile. He has a hi-res image of the center a Benchoff Buck which is well suited to being converted to a PCB. There is only a few colors and they have sharp edges. Bitmap2Component in Kicad, can easily detect these transitions and convert them into a footprint file. With the help of a text editor, I was able to manually layer everything into one complete image.

 

The KiCad design files are available on GitHub:
