nickjkl created this breakout board to free up some breadboard space:
contains two I2C temperature sensors: a TC74 and a DS1631 because only one temperature sensor is never enough
KiCad design files and MSP430 Energia sketch example are available on GitHub:

This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. Already, we’ve taken a look at the pre-history of PCB design with…
Be able to make & upload MagSpoof with variable tracks, to use it without Arduino dependencies, and implement it on the same Raspberry GPIO.
More details are available on Salvador’s blog.
The makefile and the modified MagSpoof library are avialabel on GitHub:
MagSpoofPI
The board can be used to monitor the environment conditions, and store or transmit the data to a remote system for further processing.
Serge has shared the board on OSH Park:
From the Facelesstech blog:
Normally you would use through hole then either have a 90 degree headers or just bend them over. [..] I had a brain wave, why don’t I lie the header down flat on the board and solder it to a SMD pad

Hackaday reports:
[Elliot] wrote in with his OpenFixture model for OpenSCAD. It’s awesome because it takes a small problem, that nonetheless could consume an entire day, and solves it neatly. And that problem is making jigs to test assembled electrical products: a PCB test fixture.
In the PCB design software, you simply note down the locations of the test points and feed these into the OpenSCAD model. [Elliot] shows you exactly how to do it using KiCAD. There are a few more parameters of the model that you can tweak to match your particulars, but you should have a DXF outline for a test jig in short order. Cut that out, assemble, and test.
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…

OSH Park engineer Jenner Hanni posted on Wickerbox Electronics about his LiDAR project for the Teensy 3.2:
Teensy 3.2 daughter board to display the results of a LiDAR-Lite rangefinder on an LCD screen, with three buttons, two LEDs, and a micro-SD card for datalogging.

What to do when a piece of test equipment is too expensive? Henrik Forstén decided to design and build his own:
Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits
Since I can’t afford even a used VNA I decided to make one myself with a budget of 200€, tenth of what they cost used and about 1/100 of what they cost new
