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:
Shane Ormonde wrote on the Tindie blog about the Chaos Computer by Tom Quartararo:
It turns out you can solve ordinary differential equations using simple op-amp circuits. Paul Horowitz, author of the famous book The Art Of Electronics took an interest in the Lorenz Attractor and made a circuit to solve the Lorenz Attractor equation
BoosterBot turns a TI Launchpad into a fully functional robot:
Perfect for anyone who wants to get started with MSP430 and robotics, or just wants an easy to use robotics platform to build off of.
The design files and source code are available on GitHub:
Hylian/BoosterBot
Here’s a video of the BoosterBot in action:
Kevin Rye decided to build a 15 inch long digital clock after acquiring these 3 inch 7-segment displays. He documented the project from start to finish:
I picked up these sweet LUMEX S101D22TR 7-Segment LCDs the other day.
The PCBs for the hours, minutes, and seconds display modules are identical. They’ll just be wired differently.
On the driver boards, data flows in from the left out to the next section on the right.

We love PCBs, so we were excited to see this beautiful circuitry from Lumen Electronic Jewelry:
Fashion Gets Geeky
Lumen is the creation of Robin and Marty Lawson in Madison, Wisconsin:
We’re life-long tinkerers, siblings, and fourth generation mechanical engineers.
They’ve designed soldering kits for all levels: beginner, intermediate, and advanced surface mount soldering. This heart is an example of an intermediate kit:
Lumen also makes beautiful fully-assembled LED jewelry:
Solar powered twinkling LED jewelry. No batteries, hours of blinky.
We particularly like this twinkling fiberglass cephalopod:
Each octopus has 16 amber LED lights throughout the arms connected to 12 tiny solar cells. So your necklace will charge and blink all on its own, no batteries required.
Robin tells me that they use Free PCB for layout:
Robin informed me that they laser their own stencils out of thin mylar sheets at their local Makerspace, Sector 67:
It is expensive but has a long working life, excellent hardness and optical clarity, as well as UV resistance to yellowing.
Luke Weston created this DIY radar board:
A basic radar system makes radar accessible at low cost for experiments with rangefinding & navigation of autonomous aircraft or spacecraft.
Knudt designed this board to connect an inexpensive dual-band GSM module with to an Orange Pi or Raspberry Pi:
The config files and EAGLE design files can be downloaded from the Hackaday.io project:
Paul Stoffregen of PJRC designed this shield as a Kickstarter reward earlier this year:
Please understand this shield has very limited software support at this time. However, Manitou’s early benchmarks show excellent performance we can someday hope to achieve as the software matures.

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
