WS2812B Ring Kit
WS2812B LEDs are digitally addressable RGB LEDs. Each RGB LED comes in a small 5050 package with 4 pins: Vin GND DIN DOUT Daisy-chaining is…
DIY Signal Generator Kit
I soldered a digital oscilloscope. Now I need a device to generate signals. Let’s produce a cheap signal generator kit for this very purpose. In…
Digital Oscilloscope
Oscilloscopes are expensive. Why not get a cheaper alternative? What I learnt: I didn’t know you can get inductors in the resistor package (L1, L2,…
