Part of learning to be an engineer is understanding the tools you need to work with – voltmeters, spectrum analyzers, things like that. But why use two or eight where one will? The Moku: Go combines several frequently used tools in a compact package, saves space on your workbench or in the classroom and at the same time offers a modern, software-configurable interface. Creator Liquid Instruments just raised $ 13.7 million to make this device available to students and engineers everywhere.

The idea behind it Moku: Go is largely the same as the company’s previous product, the Moku: Lab. Using a standard input connector, a number of FPGA-based tools perform the same types of noise and electrical signal analysis as they would on a larger or analog device. However, being digital saves a lot of space that is normally required for bulky analog components.
The Go goes further than the laboratory with this miniaturization, doing many of the same tasks at half the weight and with some useful additional functions. It is intended for use in educational institutions or smaller machine shops where space is limited. Combining eight tools into one is a big hit if your bank is your desk and filing cabinet too.
By the way, these eight tools are: waveform generator, arbitrarily Waveform generator, frequency response analyzer, logic analyzer / pattern generator, oscilloscope / voltmeter, PID controller, spectrum analyzer and data logger. It’s hard to tell if that’s really more or less than eight, but it’s definitely a lot in a hardback-sized package.
You access them and configure them through a software interface instead of a series of controls and dials. Although it is clear, there are good arguments for both. However, if you’re teaching a few young digital natives, a clean point-and-click interface is likely a plus. The user interface is actually very attractive; You can see several examples of Click on the instruments on this page, but here is an example of the waveform generator:

Love these pastels.
The Moku: Go currently works with Macs and Windows, but does not yet have a mobile app. It can be integrated into Python, MATLAB and LabVIEW. Data goes over Wi-Fi.
Compared to the Moku: Lab, it has some advantages. A USB-C port instead of a mini, a magnetic power connector, a 16-channel digital I / O, an optional power supply with up to four channels, and of course half the size and weight. Some things are compromised – no SD card slot and less bandwidth for the outputs, but if you need the range and precision of the more expensive tool, you probably need many other things as well.

Since the smaller option is also $ 500 (“a textbook-like price” … yikes) compared to the large $ 3,500, significant savings are required. And it’s definitely cheaper than buying all of these instruments individually.
The Moku: Go is “deeply geared towards college education,” said Doug Phillips, vice president of marketing at Liquid Instruments. “Professors can use the device in the classroom and individuals such as students and electrical engineering hobbyists can experiment with it in their free time. Since its inception in March, most of the time students have bought the device under the direction of their university. “
About a hundred professors have signed up to use the device as part of their fall courses, and the company is working with other partners in universities around the world. “There is a real need for portable, flexible systems that can handle the breadth of the four-year curriculum, ”said Phillips.
Production will begin in June (samples will be given out to testers) whose rigor and cost likely sparked the latest round of funding. The $ 13.7 million comes from existing investors Anzu Partners and ANU Connect Ventures as well as new investors F1 Solutions and Moelis Australia’s Growth Capital Fund. It is a convertible bond “ahead of an expected Series B round in 2022,” Phillips said. It’s a larger amount than they initially wanted to raise, and the note nature of the round isn’t standard either, but given the troubles hardware companies have faced over the past year, some irregularities are likely to be expected.
Undoubtedly, the expected B-Round will depend significantly on the success of the launch and acceptance of Moku: Go. But this promising product looks like it could be commonplace in thousands of classrooms in a few years.
