Sprockets, wheels, and gears, oh my! We really like our DC hobby motors but unless you have a 3D printer it can be a challenge to get fun add-ons. That's why we've got this 3-Bladed Tri-foil Propeller - it snaps on like a breeze (pun intended!) perfect for making a fan, blowing bubbles, or propelling something through the air. Comes 1 x per order

Yes, this is an adorable small television! The visible display measures only 2.5" (6.35cm) diagonal, the TFT comes with a NTSC/PAL driver board. The display is very easy to use - simply connect 6-12VDC to the red and black wires, then connect a composite video source to the yellow and black wire. Voila, a television display! There's one little button to adjust the LED backlight brightness up and down.  There is no other...

Humidity is notoriously difficult to measure. Some of the scientific and electronic considerations to measuring humidity include: analog to digital interface and external circuitry which might require op-amps or oscillator circuitry; temperature compensation adjustments to calculate dew point; calibration against a known humidity source; mounting, protection and response time in the real-world. If you're interested in the details see Tracy...
