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”.)
A Software Developer’s Guide to Getting Started with FPGAs – Part 2
In Part 1 of this series, we explored some of the reasons you might want to use an FPGA instead of or along with an MCU. We also looked at a couple good introductory mainstream FPGA development boards. In this episode, we’re going to start examining the process of creating FPGA designs. Contrary to what […]

A Software Developer’s Guide to Getting Started with FPGAs – Part 1
The good news is that that it has never been easier (or cheaper) to get into FPGA development than it is right now. Capable FPGAs are available for about the same price as a Raspberry Pi 4. Open source tools are available to avoid locking yourself in to a particular vendor or shelling out extra money for a design system.
