What do you think Geoff got Chris to test our new Formaldehyde sensor with?
Halloween answers only 馃巸馃懟
And happy belated birthday Chris!
Our deal of the week features the WVR Audio Development Board.
WVR is a next-generation sample player powered by an ESP32. WVR is Arduino compatible and open-source, and fits on a common breadboard, with room to access all the pins.

Combining a love of golf with a passion for open-source electronics?
The result is what maker Coleman Rollins calls Open GPS, an open-source device that lets golfers measure their shots, track which clubs they're using, and save their data for later.

We've released some updated current sensors and realized that it could be a little confusing which sensor could be right for you. So let's go over a basic overview of what current is and the most popular current sensors that we carry!

70 volts measured on the PHY side of an Ethernet transformer during a hot-plug event, on a circuit rated for 3.3V. It's really an analog problem disguised as a digital one.
This is the latest Paul's Deep Dives post. Read all about it at

We dug into the full analog side of Ethernet on Teensy 4.1, including where MAC addresses actually live, how transient protection works (and fails), and why transformer isolation isn't the same as transient immunity. news.sparkfun.com/17301
When we talk about @xrpRobots, the conversation is often around middle- + high-school classrooms, but XRP is being used in colleges and universities too!
Let's see what @WPI, @CornellSystems, CU Boulder, NH Community Colleges, and @MNSUMankato are doing!

The new SparkFun STCC4/SHT40 Qwiic CO2 Sensor is a simple indoor air quality breakout that measures CO2 concentration.
While most sensors measure estimated CO2 concentration, this uses thermal conductivity to directly measure actual CO2 concentrations.

Teaching robotics doesn't have to be difficult! With the XRP, you can progress students from Blockly to MicroPython, adding sensors and learning skills like computer vision along the way.
One robot enables years of learning!

Introducing the new Qwiic Formaldehyde Sensor, utilizing the miniature SFA40 from @sensirion!
The SFA40 from Sensirion is an electrochemical sensor that maintains accurate formaldehyde measurements in environments that have other common indoor gases!

Ever wanted to make a human motion alarm (not to be confused with just a motion alarm)? Now you can! Using just a Teensy, a sensor, and a few small parts, professional maker Jeremy Cook shows us how simple this practical project can be!

The XRP wasn't designed to be a "build it once and move on" robot. Start with Blockly, move to Python, add sensors, experiment with autonomous robotics, keep going.
It's less about one robot, and more about how far you can take it.
