One day KiCad Crash Course

We’ve asked Michael Welling of Qwerty Embedded Design to come to Reno to drop some knowledge on KiCad, an open source and multi-platform schematic capture and PCB layout tool. Michael uses KiCad for some of his famous designs such as LoFive, PocketBone, and BaconBits. Space is limited and you should have some basic electronics and CAD skills under your belt already to make the most of this unique opportunity.

This event will be recorded and live-streamed to the GroupGets YouTube channel.

Mary Etta West at SparkFun has remixed Anouk Wipprecht’s Kitty Ear project to make it react to audio:

Audio Reactive Wearables

At the beginning of this year I began prototyping an audio reactive headband to wear in my everyday life, like while dancing with my dog in my lab listening to Legend of Zelda dubstep.

 A few weeks ago I saw this post by my favorite Engineer/Maker/FashionTech Designer/Roboticist Anouk Wipprecht – a kitty ears soldering project with 3D-printed headband. I immediately ordered the Electronic Kitty Ears Headband from Shapeways, and after more digging around I found the Instructables tutorial for the kitty ears soldering project. The tutorial includes the BOM, the .stl files for the headband and a link to the OSHPARK shared project.

I downloaded the gerbers and exported the dimension layer as a gerber by itself. Then I imported it to the dimension layer in EagleCAD so I knew I had the same dimensions and my circuit would fit in the Kitty Ears headband. You can see the prototypes in the first picture. In a day I captured the schematic from the original prototype circuit and laid out the PCB design in the Kitty Ears form factor.

The design files and source code are available on GitHub:

Dublin Knows How to Bring-a-Hack

Dublin Knows How to Bring-a-Hack

When on the road, we love to stop by a local hackerspace and connect with the hacker community. On Friday, TOG Hackerspace in Dublin, Ireland opened their doors to host a Bring-a-Hack with Hackaday and Tindie.

TOG is a Gaelic word which loosely translates as “to make”. Declan met us for the beer drop and gave us a tour when we returned for the evening event. The building is divided into several different spaces, starting with an entry area that serves as a meeting space, gaming room, and showcase of projects.

Ada Lovelace Fellowships For 2018 Open Hardware Summit

The Open Source Hardware Association is now accepting applications for the Ada Lovelace fellowship which provides free admission to the Open Hardware Summit and a $500 travel stipend. One of OSHWA’s goals is to foster a more diverse community within open source. As part of this, Ada Lovelace Fellowships are open to women, LGBTA+, and people of color. There are a total of 10 fellowships available and applications are due by April 30th. The Open Hardware Summit will be held on September 27th at MIT.

The fellowship program, founded by Addie Wagenknecht and Alicia Gibb in 2013, builds on the ideal that Open Hardware is one way to reduce the barriers associated in access to technology. Removing some of the financial barriers associated with attending the Summit will help to ensure more people of diverse backgrounds are involved in shaping the Open Hardware world. In addition to the talks shared at the gathering, over the last several year OSWHA has been evolving the Open Hardware definition and an Open Hardware certification.

2018 Hackaday Prize: Build Hope. Design the Future

fustini, , Leave a comment

Every year we are inspired by the projects entered into the Hackaday Prize, and we are excited that the 2018 Hackaday Prize season has begun:

This is our global engineering initiative with huge prizes for those hackers, designers, and engineers who want to use their skill and energy to build something that matters. This year, we challenge you to Build Hope. Show the world the amazing ways technology enriches humanity, and that its benefits can be shared by all. There is over $200,000 in cash prizes headed to the most interesting hardware builds of the year. With plenty of room for great ideas, the top 100 entries will each receive a $1,000 cash prize and continue …

Have you entered a project into 2018 Hackaday Prize?

For this year’s Hackaday Prize, we started an amazing experiment. World Create Day organized hundreds of hackerspaces around the world to come together and Build Hope for the future. This was an experiment to bring community shops and workspaces together to prototype their entries for the Hackaday Prize, and boy was it a success. We had hackerspaces…

Digi-Key presents An Intro to KiCad – Part 1: How PCBs Are Made with Shawn Hymel:

Digi-Key Electronics presents: An introduction to KiCad with engineering superhero Shawn Hymel. In the first part of this series Shawn discusses how PCBs are made and the benefits of utilizing KiCad as a design tool. KiCad is a free and open source platform which makes it great for learning how to make your own PCBs while still being powerful enough to do more complicated design work.

Estimated Time of Arrival (ETA) Nixie Tube Clock

What is an ETA Nixie Tube Clock and How Do You Build One?

https://surfncircuits.com/2018/04/01/what-is-an-eta-nixie-tube-clock-and-how-do-you-build-one/

The ETA Nixie clock is programmed to display the normal time and up to ten different ETA times that are easy to identify and visually stimulating. The current time is displayed for 5 seconds (i.e. 8:41:38 AM), then up to ten different ETA destinations are displayed for three seconds each before the cycle is repeated. The current time displays all six digits including seconds. The ETA locations are numbered and display hours and minutes without seconds helping to distinguish between them.  In our house, the ETA to work is ETA number 1 (i.e. 9:07 AM) and the ETA to school is ETA number 2 (i.e. 8:58 AM). Lots of other options are possible with custom programming of the Raspberry Pi to meet your ETA requirements.

CrowdSupply is organizing a new hardware con named Teardown in Portland on the weekend of May 11th – 13th:

teardown-collage-02_png_project-tile

Teardown 2018

A party for hacking, discovering, and sharing hardware

Teardown is an event put on by Crowd Supply in association with Make+Think+Code @ PNCA. You can think of Teardown as live-action Crowd Supply, but with fewer cardboard boxes and packing peanuts. We’ll be bringing together hardware aficionados from around the world to celebrate, inspect, create, and, of course, tear down hardware.

There will be long-time Crowd Supply creators and backers, as well as people we’re meeting for the first time. There will be hardware, art, food, drink, puzzles, workshops, tutorials, talks, music, field trips, and friends. Most of all, there will be ideas and projects to explore and inspire. We hope you’ll be there too!

Latest update: Andrew “bunnie” Huang to keynote Teardown

Please considering submitting a proposal like a talk, workshop, demo or installation:
