Two new versions of the STTS22H Temperature sensor are now available with a new version of the updated LiPo Fuel Gauge!
Today, we release a new Power Supply Sample Kit along with a few new SparkX Products and a programmer for your ESP projects!
We have a load of new products to show off today, and most of them are miniaturized versions of popular peripherals.
A new limited edition Thing Plus is now available, along with new RTK Plus products and a new power supply instrument for your workbench (or on the go)!

That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
