Hackster.io is organizing a Google Android Things Meetup in San Francisco on Thursday, January 18th:
Be sure to register on the Eventbrite page:
Have you ever wanted to design and develop your own products? Android Things lets you build professional, mass-market products on a trusted platform without previous knowledge of embedded system design. With an easy-to-use software development platform based on Android Studio and access to the Android SDK you’ll be on your way to developing the next big IoT product.
Wayne Piekarski, a Developer Advocate from Google will be showcasing the capabilities of Android Things and how you can get started building your product with this platform.
Here’s a talk with Wayne Piekarski earlier this year at Google I/O:
From Prototype to Production Devices with Android Things (Google I/O ’17)
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…

A holiday project by Dan Hienzsch (@rheingoldheavy) to build a little Snowbot with an adjustable speed larson scanner for an eye:
The Snowbot has three major subsystems: Power and Timer and Display.
The power subsystem uses a 3.7V LiPO battery boosted to 5V with an SC4503 boost converter to power the fully analog circuit. It requires a set of passive components in order to generate the higher voltage.
The timer subsystem is comprised of a 555 IC that generates a clock signal. The speed of the clock is adjusted by twisting the potentiometer (the nose of the snowbot). The clock signal ticks through the outputs of a CD4017 decade counter, lighting each LED in sequence, then moving back through them again.
The display subsystem involves taking the output of the CD4017, and directing it to six red LEDs in the form of a larson scanner. In addition to lighting the LED, the current also charges a 22uF capacitor through a diode. When the output moves to the next LED, the cap discharges through a 2.2K resistor (part of a resistor network), fading the LED out gracefully.
Sarah Petkus is a robot mom (which means she’s the mother to a robot, not that Sarah herself is a robot, at least as far as we’re aware), whose child, Noodle Feet, is a character in Sarah’s graphic novel Gravity Road. Unlike every other robot on the planet, Noodle Feet is a content-based robot. Instead of…

Alex Glow of Hackster.io takes a look at the OSHWi octopus badge designed by Gustavo Reynaga:
The design files and source code are available on GitHub:
GReynaga has shared the board on OSH Park:

It is a staple of spy movies. The hero — or sometimes the bad guy — sticks a device never any bigger than an Alka Seltzer to a vehicle or a person and then tracks it anywhere it goes in the world. Real world physics makes it hard to imagine a device like that for…

The 555 timer is one of that special club of integrated circuits that has achieved silicon immortality. Despite its advanced age and having had its functionality replicated and superceded in almost every way, it remains in production and is still extremely popular because it’s simply so useful. If you are of A Certain Age a…
