The 2017 Open Hardware Summit is the annual gathering of the OSHWA organization and open hardware community. We are a 501c3 not for profit. Our goal of the Open Hardware Summit and Community is to create an inclusive welcoming environment to empower people in all stages of discovering open source.
The Summit is seeking submissions for talks from individuals and groups working with open hardware and related areas. Topics of interest for the summit include, but are not limited to:
Wearables, e-textiles, and fashion tech
Means of supporting collaboration and community interaction
On demand and low volume manufacturing
Distributed development and its relationship to physical goods
Software design tools (CAD / CAM)
Ways of sharing
Competition and collaboration
Sustainability of open hardware products (e.g. how to unmake things)
Open hardware in the enterprise
Specific product domains: e.g. science, agriculture, communications, medicine
Legal and intellectual property implications of open-source hardware
Open hardware in education
Addressing the gender imbalance or other types of under-representation in the open hardware community
For the 4th year, the Summit is offering up to tenOpen Hardware Fellowshipsto members of the community which includes a $500 travel stipend:
The Ada Lovelace Fellowship was founded in 2013 prior to the annual Open Hardware Summit at MIT by Summit Chair Addie Wagenknecht and OSHWA Director Alicia Gibb as a way to encourage women, LGTBA+ and/or other minorities in open technology and culture to actively participate and foster a more diverse community within open source.
Do you like Open Source? Join Hackaday and Tindie at the largest community-run Open Source conference in North America. We’ll be at the Southern California Linux Expo next week, and we want to see you there. What’s happening at SCALE this year? Amateur radio license exams, a PGP signing party, Bad Voltage Live and The Spazmatics, and…
This is the same chip used in most all of the RTL-SDR dongles, as well as the Airspy and numerous other radios. The chip is a versatile front-end with reasonable sensitivity and wide tuning range.
The design presented here is almost an exact implementation of the Mfg’s suggested demo design from the datasheet, implemented on the OSHpark 4-layer PCB process and provides a simple 4-pin interface with power, ground and I2C bus for controlling the tuner. A broad-band RF input and 10MHz IF output are provided on SMA connectors.
The breakout PCB design and STM32F0 firmware for the Rafael R820T2 tuner chip are shared on GitHub:
The chat functionality on Hackaday.io is quickly turning into the nexus of all things awesome. This Tuesday, February 28th, everyone’s favorite robotic dog is talking certifications. Everything from FCC to UL to OSH to CE and the other CE is on the table. If you want to build hardware, and especially if you want to…
This is a breakout board for the Intersil ISL12022M real-time clock, with optional I²C pull-ups and a CR1225 backup battery. The circuit is based on the design recommended by Intersil, with a few tweaks. It’s the second board I’ve designed so far.
[Max K] has been testing the battery life of his self-designed watch under real-world conditions. Six months later, the nominally 3 V, 160 mAh CR2025 cell is reading 2.85 V, so the end is near, but that’s quite a feat for a home-engineered smart watch
I’ve been working on, replacing the NAND raw flash with an eMMC chip on the CPC2.0 board.
I wrote about raw flash and the challenges of writing a flash translation later in part 16 of this series. After some research, I concluded that the eMMC interface looked exactly like the much more common SDCard interface, albeit that the interface can be run with an 8-bit width. SDCards are limited to 4 bits by the physical pin count. Taking a gamble I created a board to test this new eMMC chip. I created a fake SDCard!
This fake card allowed me to check very quickly if my assumptions were correct both at a hardware and a firmware level. I wanted to be sure that it was possible to interface the eMMC via 4 bits, rather than the full 8 bits and be sure the firmware instructions were the same between these two technologies.
I personally love the concept of electronic boards connected in “slots” (vertically attached to a horizontal board), like most industrial-grade PLC’s or even our desktop’s expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!
