LED Strip Raspberry Pi Adapter

Henner Zeller created the Spixels project to control 16 LED strips at once from a Raspberry Pi:

Spixels

The Spixels library and PCB to control SPI-type LED strips was originally developed for the Noisebridge Flaschen-Taschen project, but broken out as separate project because it is independently useful for many other LED strip applications.

hzeller shared the board on OSH Park:

Native Kicad uploads

Continuing with our goal to simplify Open Source Hardware fabrication, we’re very pleased announce that we’re finally able to accept direct uploads of KiCad PCB design files on OSH Park!

For designers, this means that you can place an order without going through the plot process, worrying about drill formats, or fiddling with CAM settings.

For the community, this means ordering files designed with KiCad got a lot easier.  Now there’s no need to install KiCad to generate gerber files, or deal with a zip full of gerbers that might not be set up for us.

For users who still prefer to generate gerbers, we have good news for you too. We’ve improved our file detection, so there’s no need to rename the files on our behalf. Check out our Kicad docs for more information on generating gerbers if you run into trouble.

We’d also like to extend a word of gratitude to the developers for their continued efforts to improve KiCad.  In the last few months, they’ve added too many features to count, including the scripting architecture.  A special shoutout to Adam Wolf of Wayne and Layne in particular, for his support of these feautures!

1575 Bottle of Beer on the (LED) Wall — Hackaday

Say hello to my little friend, lovingly named Flaschen Taschen by the members of Noisebridge in San Francisco. It is a testament to their determination to drink Corona beer get more members involved in building big displays each year for the Bay Area Maker Faire. I pulled aside a couple of the builders for an interview…

FR4 Machine Shield Is A CNC Milling Machine From FR4 PCB — Hackaday

The people behind the PocketNC heard you like CNC PCB mills, so they milled you a PCB mill out of PCB. They announced their surprising new open source hardware product, a pocket sized 3-axis CNC machine entirely made out of FR4 PCB material, aptly named “FR4 Machine Shield”, at this year’s Bay Area Maker Faire. We know the concept…

It’s Time to Finally Figure Out How to Use KiCAD — Hackaday

KiCAD has been making leaps and bounds recently, especially since CERN is using it almost exclusively. However, while many things are the same, just enough of them are different from our regular CAD packages that it’s hard to get started in the new suite. [Chris Gammell] runs Contextual Electronics, an online apprenticeship program which goes from…

SubPos Positioning System

Blecky developed a Wi-Fi positioning system to be used where GPS won’t reach:

SubPos Positioning System

SubPos is an indoor positioning system that can be used in various environments such as metro lines, shopping malls, carparks, art galleries or even conference centers; essentially anywhere GPS doesn’t penetrate. It could also be integrated into an array of IoT enabled devices, from access points to Wi-Fi enabled light-bulbs.

SubPos Nodes transmit encoded information in a standard Wi-Fi beacon frame which is then used for position trilateration:

The Nodes provide a pre-calibrated device that is easy to configure and can be dotted about with ease:

Retrotechtacular: Fog Over Portland — Hackaday

In the early days of broadcast television, national spectrum regulators struggled to reconcile the relatively huge bandwidth required by the new medium with the limited radio spectrum that could be allocated for it. In the USA during the years immediately following World War Two there was only a 12-channel VHF allocation, which due to the…
