You do not know how to make a PCB unless you can make your own parts. [Jan] knows this, but like everyone else he checked out the usual online sources for a footprint for an SD card socket before making his own. It turns out, this SD card socket bought from an online marketplace was…
The 2016 Hackaday SuperConference is the ultimate hardware con. It will take place on November 5+6, 2016 in Pasadena, California. SuperCon is about hardware creation — everything at this conference is geared toward sharing the knowledge, excitement, experience, and motivations that go into building cutting edge electronics. We offer you 48 hours packed with 21…

Portland Science Hack Day at XOXO Outpost kicks off tonight after the Open Hardware Summit! Opening Lightning Talks start at 7:15 pm:
Here are my slides on Open Source Hardware and Science [PDF]:
Slides are also shared on SlideShare
Kevin Rye recreated this replica from a favorite movie:
The Fifth Element is one of my all-time favorite movies. I watched it again the other day and as soon as I saw Zorg’s Door bomb, I said to myself, “I’m so building that!”
Here it is in action:
A Raspberry Pi Zero is down to a price and size where it’s just begging to be integrated into your projects. Unless, that is, if your project involves a lot of 5 V equipment. Then it’s just begging to be fried. [David Brown] solved this problem by breaking out pins with level converters. He used…

Please join us tomorrow night on Open Hardware Summit eve for a delightful mix of #BringAHack and open house!
Refreshments will be served. No problem if you won’t be able to bring a “hack”. There will still be plenty of interesting things to experience!
We’ve been trying fit in a tour of the Pacific Northwest for a couple of years now. This week is a perfect excuse. Hackaday is proud to sponsor the Open Hardware Summit which will be held in Portland this Friday! Hackaday believes in the free and open sharing of information and ideas. Open Hardware has…

For the next post in the Creating A PCB series, we’re going to continue our explorations of Eagle. In Part 1, I went over how to create a part from scratch in Eagle. In Part 2, we used this part to create the small example board from the Introduction. This time around I’ll be going over Design […]

I put together an I2C interface board for these displays based on a design by Adafruit, using a Holtek HT16K33 RAM Mapping 16*8 LED Controller Driver chip.
A nice feature of this chip is a dimming command that provides display dimming in 1/16 increments.
Barbouri has shared the board on OSH Park:
Due to the nature of the breakout, many components can be omitted depending on the needed sections.

| Large (100uF+ cap) | 2 | 0603 or larger | any |
The various use cases may or may not require some or all of these pins. Here’s the most you can solder to the board in the simplest orientation
Most of these can be swapped, omitted, or assembled with small 1×3 connectors or whatever you have on hand. Otherwise, they can be purchased at Digikey or Adafruit
