Let's just say, hypothetically, that someone wanted to take over your webcam and observe your every move. And let's just say you didn't want them to - because, hypothetically , you were building an open-source white hat firewall, or an CircuitPython chaos inciter, or you can only do one pull-up and just ate a whole bag of Bugles. Then maybe spending a couple bucks on a webcam blocking sticker wouldn't seem so ridiculous....

Since we first started carrying NeoPixels back in 2012, the chainable RGB LEDs have taken over the world. And a big part of that success is due to the simplicity of their wiring - just one data wire, no matter how many pixels you've got. So no surprise they're everywhere , blinking away in art exhibits, maker faire demos, DJ booths, decorations and costumes. But, at some point, every NeoPixel'er bumps into the constraints of that...

These durable (but affordable!) gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a  TT DC All-Metal Gearbox Motor  with a gear ratio of  1:90 about double of the 'standard' 1:48 ratio. That gives them higher torque but slower rotational speed. Since they're slower they're good for robots where strength is more important than speed. They look a lot...
