EspoTek Labrador Oscilloscope
The EspoTek Labrador is billed as an all-in-one oscilloscope, signal generator, power supply, logic analyzer, and multimeter. How does this tiny $29 USD board measure up? Let’s find out!
AD9833 Waveform Generator
A waveform generator is a handy little tool for stimulating and testing electronic components and assemblies. Any work with filters, amplifiers, or other frequency-sensitive designs can benefit from the insights gained through a controlled signal input. Here’s how to make one for about $30.
ATtiny85 Neopixel Controller
The Atmel ATtiny85 is capable little 8-bit microcontroller that plays very well with the Arduino ecosystem. It also comes in a compact and maker-friendly 8-pin Dual Inline Package (DIP), operates on 5V, and costs less than two dollars – making it a great option for controlling some WS2812b RGB LEDs (aka “neopixels”.)
