Zoolark is a tiny multi-tool for learners and makers that contains an oscilloscope, signal generator (triangular, square sinusoidal and PWM), DC bias, and spectrum analyzer. While it won’t replace your bench-top instruments, it can definitely be your second electronics analysis tool (after your pocket multimeter). It is easy to use (just three buttons and a toggle control!), cheap to buy, and sports an excellent array of features, all of them useful.
I purchased my Zoolark a few months ago during it’s Kickstarter campaign. After leaving it on my desk for a few months while I was busy with KiCad Like a Pro, I finally got to it. I spent the last couple of days playing with it.
Zoolark is made by EIM Technology, who also make the FPGA development board that I used to learn the basics of FPGA (learn more about this in a separate blog post).
In this post, I share a comprehensive video where I show you what you can do with Zoolark.
