SparkFun Electronics ☛ Carbon Dioxide Sensing: PAS vs NDIR vs TVOC
We offer quite a few environmental sensors here at SparkFun, and we thought it'd be cool to give you a look under the hood to see how they actually do their jobs! Starting today, we're going to look at CO2 sensors. We have a few different types that use different technologies to sense CO2 concentration in the air, and today we're going to dive into Photoacoustic Spectroscopy, Non-Dispersive Infrared, and Total Volatile Organic Compounds. Let's go!

Arduino ☛ A gaming platform tailored to those with special needs
As a society, we have decided to enact some measures to make our world more accessible to those with disabilities. Wheelchair ramps, for example, are often legal requirements for businesses in many countries. But we tend to drop the ball when it comes to things aren’t necessities.

[Old] Tony Finch ☛ I made a keyboard!
So instead of relying on someone else to make a keyboard I like, I could make one myself! My own PCB and switch plate, designed for just the layout I want.
And with QMK open source firmware, I can make good use of the fn key that was so disappointingly unconfigurable on the HHKB and Apple keyboards.
