We are very excited about the Flexible PCB Concept Contest on Hackaday:
Have you ever wanted to try using a flexible PCB in your project but just haven’t gotten around to it?
Well this is your chance!
Want free flexible circuit boards?
You don’t have to build something to win. Show us what you want to design.
#bringahack Bay Area is coming up on May 19th! Please join us for this wonderful tradition that Jeri Ellsworth started:
Sunday evening, May 19th, at BJ’s in San Mateo, 6pm to 12am
2206 Bridgepoint Parkway
San Mateo, CA 94404

Exciting times for people in Chicago that like hardware!
Tonight, Thursday, April 25th is Hardware Happy Hour (3H) Chicago at Ballast Point! It’s an informal hardware show ‘n tell that is a lot of fun:
And KiCon 2019 begins tomorrow! Come learn more about designing circuit boards with KiCad.
There is also a party at Chicago hackerspace Pumping Station: One on Friday night and then a Bring-A-Hack party with Hackaday on Saturday night.
Look for our Drew Fustini (@pdp7) in purple at all the above events!
Glen Atkins writes controlling an industrial stack light over USB using a PIC16F1459 USB microcontroller and a PCA9685 I2C PWM LED controller:
After using the PIC16F1459 to build numerous USB HID input devices including a giant keyboard, a tiny keyboard, and a big red button, it was time to see if the PIC16F1459 could be used to control outputs too. Sticking with the industrial theme, I chose to build a USB controller for a, um, stack of industrial stack lights.
Industrial stack lights are usually used to indicate the status of machines on production lines. Green could indicate all is functioning normally, yellow could mean the machine is running low on input material, and red could indicate the machine jammed and needs intervention.
For a simple, quick project such as this one, one does not want to have to write a custom USB driver for a Mac, PC, or Linux box. The best way to avoid writing a custom driver is to use an existing USB device class that lends itself to controlling custom hardware. The USB Human Interface Device (HID) and USB Communication Device Class (CDC) device classes both support controlling custom hardware.
KiCad is the electronic design automation software that lives at the intersection of electronic design and open source software. It’s seen a huge push in development over the last few years which has grown the suite into a mountain of powerful tools. To help better navigate that mountain, the first ever KiCad conference, KiCon, is happening next week in Chicago and Hackaday is hosting one of the afterparties.
The two days of talks take place on April 26th and 27th covering a multitude of topics. KiCad’s project leader, Wayne Stambaugh, will discuss the state of the development effort. You’ll find talks on best practices for using the software as an individual and as a team, how to avoid common mistakes, and when you should actually try to use the auto-router. You can learn about automating your design process with programs that generate footprints, by connecting it through git, and through alternate user interfaces. KiCad has 3D modeling to make sure your boards will fit their intended enclosures and talks will cover generating models in FreeCAD and rendering designs in both Fusion360 and Blender. Dust off your dark arts with RF and microwave design tips as well as simulating KiCad circuits in SPICE. If you can do it in KiCad, you’ll learn about it at KiCon.
Of course there’s a ton of fun to be had as interesting hackers from all over the world come together in the Windy City. Hackaday’s own Anool Mahidharia and Kerry Scharfglass will be presenting talks, and Mike Szczys will be in the audience. We anticipate an excellent “lobby con” where the conversations away from the stages are as interesting as the formal talks. And of course there are afterparties!
- Friday 4/26 Pumping Station: One, the popular Chicago hackerspace now celebrating its 10 year anniversary, is hosting an afterparty (details TBA)
- Saturday 4/27: Hackaday is hosting an after party at Jefferson Tap from 6-8:30. We’re providing beverages and light food for all who attended the conference.
