One of the favorite pastimes of electronics hobbyists is clock making. Clocks are a simple enough concept with a well-defined goal, but it’s the implementation that matters. If you want to build a clock powered only by tubes and mains voltage, that’s a great skill tester. A relay-based timepiece is equally cool, and everyone should…

tl:dr The one bug bare about running a ‘headless’ raspberry pi is shutting it down when something goes wrong. I started looking into what other people had done, I quite liked the look of the turnoffeepi but hated how it covered valuable I2C pins. This is why I decided to design my own shutdown button. […]
tl;dr As of writing this the raspberry pi zero is still hard to get hold of, Since I managed to snag one I thought I would put it some use. Also Hackaday/Adafruit gave me a kick up the arse with there Contest too. I haven’t really done anything with raspberry pi GPIO before now. I had […]

Part hackathon, part geek social, these biweekly meetings are a time for you to come join others for insight, inspiration or just insanity. Bring your toys for others to see, or come see what others have been painstakingly chipping away at in their spare time.
When: Monday, May 30, 7:00pm – 11:00pm
7608 North Interstate Avenue, Portland, OR
We have roughly 1200 square feet of general purpose area for both large events and individual use including a lounge with board games, configurable workspaces, power strips, internet, projectors and a DIY Arcade Machine just for fun.
[Tisham Dhar] has been interested in monitoring AC power and previously built a breakout board for the ADE7763. He wanted to find something cheaper and more modern. The ATM90E26 fit the bill. It can communicate via a UART or SPI, and has multiple metering modes. The problem? The evaluation module from Atmel costs about $500…

Alicia Gibb, executive director of the Open Source Hardware Association (OSHWA), announced today that the month of October this year will be Open Source Hardware Month:
Open Source Hardware Month will host three significant events in an effort to bring greater clarity to the open source hardware definition, invite more people to contribute to the movement, and provide education about how to publish a project or product as open source hardware. These events include the Open Hardware Summit, an open source hardware certification, and a series of documentation days.
The Open Hardware Summit in Portland, Oregon will be on October 7, 2016. Tickets are for sale, and there is still time to be a speaker or a sponsor.
OSHWA will launch the Open Source Hardware certification at the Summit:
Users will self-certify compliance in order to use the certification logos. Self-certification will give creators the right to use the OSHWA open source hardware certification logo. As part of the self-certification process, creators will agree to subject themselves to penalties for non-compliance. OSHWA will be responsible for enforcing those penalties.
It’s been a while since we’ve seen much action on the bristlebot front, which is too bad. So we’re happy to see [Extreme Electronics]’s take on the classic introductory “robot”: the Black Line Follower. The beauty of these things is their simplicity, so we’ll just point you to his build instructions and leave the rest…
Alex Hiam created a sensor box with the LPC824 microcontroller:
I put this project together for the OSH Park Bring A Hack meetup at the 2016 Bay Area Maker Faire. It’s Tricorder inspired, but can’t quite sense everything, so the name “Bicorder” seemed fitting.
The source code is on GitHub:
Alex leveraged his ARM microcontoller board:
We loved seeing this project at Maker Faire Bay Area 2016 and #BringAHack. Hackaday has done a great blog post about it and recorded an interview with the creator:
I made a bee line for one booth in particular at this year’s Bay Area Maker Faire; our friend [Eric Schlaepfer] had his MOnSter 6502 on display. If you missed it last week, the unveiling of a 6502 built from discrete transistors lit the Internet afire. At that point, the board was not fully operational but…
Thanks to everyone that came to #BringAHack last night after Maker Faire Bay Area 2016! We had a fantastic time checking out everyone’s imaginative projects.
