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.

Bi-quinary driven Nixie tubes have nice features by requiring a low bias current and minimized shift registers, but also are sensitive to digit ghosting and require a good level of cathode poison elimination. With the procedures and circuit tricks described above, this was successful for the ETA Nixie Tube Clocks. Good luck with your testing. Let me know if you have any comments or your own improvements.
[Glen]’s project sounds perfectly straightforward: have a big industrial-style push button act as a one-key USB keyboard. He could have hacked something together in any number of ways, but instead he decided to create a truly elegant solution. His custom PCB mates to the factory parts perfectly, and the USB cable between the button and the computer even fits through the button enclosure’s lead hole.
It turns out that industrial push buttons have standardized components which can be assembled in an almost LEGO-like manner, with components mixed and matched to provide different switch actions, light indicators, and things of that nature. [Glen] decided to leverage this feature to make his custom PCB (the same design used in his one-key keyboard project) fit just like a factory component. With a 3D printed adapter, the PCB locks in just like any other component, and even lines up with the lead hole in the button’s enclosure for easy connecting of the USB cable.
This is the 2019 Hackaday Prize, the worldwide hardware design contest focused on product development. We know you can build a working prototype, and we still want to see you do that. But a great idea should have reach beyond your own workshop. This year’s Hackaday Prize is about taking your product across the finish line, from concept to design for manufacture.
PRIZES TO JUMP START YOUR PRODUCT
$125,000 and a Supplyframe DesignLab Residency await the Best Product winner. There are five focus categories this year, with the winner of each receiving a $10,000 prize. And to help encourage those early beginnings, we have another $10,000 in seed funding set aside which means up to $500 for each of the top 20 entries who get in and gather those “likes” before June first.
There are a few areas of focus you should have in mind as you work on your products. These are Concept, Design, Production, Benchmark, and Communication. All entries are eligible to receive prizes related to these, and in addition to the $50,000 we mentioned above for the winner in each area, we have another $3,000 for each set aside to recognize an honorable mention.
$200,000 is on the line and the final results will be revealed live on stage at the Hackaday Superconference in November. Your name should be in one of those sealed envelopes!
We rarely take a moment to consider the beauty of the components we use in electronic designs. Too often they are simply commodities, bought in bulk on reels or in bags, stashed in a drawer until they’re needed, and then unceremoniously soldered to a board. Granted, little scraps of black plastic with silver leads don’t exactly deserve paeans sung to their great beauty – at least not until you cut them in half to reveal the beauty within.
We’ve seen a little of what [Tube Time] has accomplished here; recall this lapped-down surface-mount inductor that [electronupdate] did a while back. The current work is more extensive and probably somewhat easier to accomplish because [TubeTime] focused mainly on larger through-hole components such as resistors and capacitors
What if there were something like a KVM switch for your micro programmer, logic analyzer, and other various tools? There was a time when KVM switches (keyboard, video, and mouse, by the way) were metal enclosures surrounding an absurdly complicated rotary switch.
ToorCamp is a five-day open air tech camping event held every two years somewhere around the northwest corner of Washington state. Think of it as something like Burning Man, except you can survive for three hours without water, there aren’t a whole bunch of scenesters and Instagram celebs flying in on private planes, and everyone there can actually build something. Oh, and ToorCamp has delivery drones that will send you creme brulee. These mini creme brulees were probably made with the hot air gun hanging off a soldering station. Don’t worry, you’re getting fresh air that’ll balance out the heavy metal poisoning.
For last year’s ToorCamp, the biggest welcome sign was a 40-foot-long illuminated ToorCamp sign. This was designed, built and coded by Zach Archer, and he was at the 2018 Hackaday Superconference to give us the details on how he made it and how it was coded.
