For a while now I have been intrigued with Integrated Light Sources i.e. NeoPixels. I knew nothing about them and with the coming of Christmas, I was inspired to take a closer look. I knew I would not have anything in place before Christmas 2017. But there is always next year.

Jens Hauke designed this charlieplexed 20 LED blinker controlled by an ATTiny45 for the Hackaday Coin Cell Challenge:
This is a small blinky with 20 LEDs powered by one CR2032 coin cell
and with an ATTiny45 brain. The firmware is written in plain C and
compiled with the avr-gcc toolchain. The PCB is a two layer design made
with KiCad.
Space efficient daisychained LED placing with shared anode/cathode soldering pads.
Firmware and gerbers are available on GitHub:
Jens has shared the board on OSH Park:
Here is a video of the LED in action:
Today you can buy flashing LEDs; a simple two-lead component that requires only a power supply to produce even flashes of light. They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a…

Wayne Stambaugh from the KiCad project be joining Hack Chat on Hackaday.io this Friday to discuss upcoming plans and features for 2018:
Friday, January 5, 2018 12:00 pm PST
- What new features are on the roadmap for 2018?
- What new features were developed since we chatted in January 2017?
- Under the hood- how KiCad development works
- How can a developer get started helping out?
This is a short 2-minute video explaining what is the Tinusaur project about, who is it good for and what you could do with its microcontroller and shield boards. The Tinusaur is a small microcontroller board with a tiny chip on it. The Tinusaur board is powered by the popular Atmel ATtiny85 microcontroller. It comes as […]

The year is drawing to a close, and we have a weekend project for you to while away the remaining hours. Take the Coin Cell Challenge! The point of the challenge is to do something interesting with a coin cell. That’s it! It’s a challenge that can be as simple or as involved as you…
2017.12.15 : Black Mesa Labs is proud to present two open-source-hardware DVI video boards for adding TMDS digital video to FPGA platforms with standard PMOD connectors. These two boards are currently available to purchase as bare fabs directly from OSH-Park, or Gerbers and design files may be downloaded from BML here. ——————————————————– BML 3bit DVI […]

Since Autodesk’s acquisition, Eagle has been making waves in the community. The de facto standard for Open Hardware PCB design is now getting push-and-shove routing, a button that flips the board over to the back (genius!), integration with Fusion360, automated 3D renderings of components, and a bunch of other neat tools. However, Eagle is not without its…
Clearly a believer in the old adage, “Go Big or Go Home”, [Ted Yapo] has decided to do something that seems impossible at first glance: starting his car with a CR2477 battery. He’s done the math and it looks promising, though it’s yet to be seen if the real world will be as accommodating. At the…
