This Tuesday night, August 15th, is Hardware Happy Hour (3H) Chicago!
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:
Simula made several new friends:
We were excited to get a look at the purple PCB inside:
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:

The next Hardware Happy Hour (3H) Chicago is Tuesday, June 13th, 6:30pm at St. Lou’s Assembly:
Here’s some photos from the previous meetups:
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.
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:
Junes-PhD has shared the project on OSH Park:
On Saturday the Hackaday community turned out in force to try something new. The first Hackaday Unconference was held in three places at the same time, and I was in Chicago and was amazed at the turnout and variety of presentations. The image above sums up the concept quite well, everyone shows up ready to…
We’re excited to announce that Chicago will play host to the Hackaday Unconference on March 18th. We are happy to expand our unconference plans to include this event at Pumping Station One from 1-8pm on 3/18. Astute readers will notice that this is the second location we have announced this week.
