Serial Studio: Easily Visualise And Log Serial Data

-

Outputting data from a microcontroller over a serial port is convenient and easy, but formatting, visualizing, and analyzing the data can be tedious and frustrating. [Alex Spataru] knows this all too well, having spent too many hours building and debugging custom dashboards. To save himself and others the same frustration in the future, he created Serial Studio, a tool for quickly building dashboards for serial data.

The only input required for Serial Studio to create a dashboard is a simple JSON structure specifying the data’s format, and how it should be grouped and displayed. Originally Serial Studio required all the JSON data to be sent over serial, which is fine for simple data but quickly becomes cumbersome for more complex applications. To solve this, [Alex] added a feature allowing the JSON document with the format information loaded from the computer, while only the data is sent over serial.

Serial Studio includes several visualization options, including raw line graphs, bar/level indicator, dial indicator, the artificial horizon for IMU data, or a map widget. It can also output the formatted data to a CSV file for further analysis in other software. A console window is also included for viewing raw data or debugging purposes. See the usage demo after the break.

We like Serial Studio’s ease of use and adaptability, and we’ll likely use it for our own projects in the future. It is compatible with Linux, Windows, and Mac thanks to the Qt framework, and the code is open-source and available on GitHub.

If you’ve ever watched one of the BPS.Space model rocket launch videos, you’ll know how critical data logging, visualization and analysis is for [Joe Barnard]’s work. Serial Studio is perfect for such applications, and [Alex] used it extensively for simulated satellite competitions at his university.

Modern Radio Receiver Architecture: From Regenerative to Direct Conversion

-

Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article . Most of the receivers you will have worked with over the past couple decades are designs by Edwin Armstrong ; regenerative, superregenerative, or most commonly superheterodyne. These are distinguished by a few fascinating key traits that bring both benefits and drawbacks. Today let’s dive into Mr. Armstrong’s receivers. I’ll also talk about DC receivers which, despite the name, are not made to listen to batteries. These are receivers you are much more likely to encounter in modern equipment. Regenerative and Superregenerative The regenerative receiver is all about doing more with less. You still see some of these in simple applications like RF remote controls. The idea derives from how an oscillator works. In a simple way of thinking, an oscillator is an amplifier with enough positive feedback that any tiny signal at the right frequency will amplify and then, throu...

Hackaday Links: May 31, 2020

We begin with sad news indeed as we mark the passing of Marcel van Kervinck on Monday. The name might not ring a bell, but his project, the Gigatron TTL computer , certainly will. We did a deep dive on the microprocessor-less computer a while back, and Marcel was a regular at conferences and on the Gigatron forums, supporting users and extending what the computer can do. He was pretty candid about his health issues, and I’ll add that when I approached him a few weeks ago out of the blue about perhaps doing a Hack Chat about Gigatron, he was brutally honest about how little time he had left and that he wouldn’t make it that long. I was blown away by the grace and courage he displayed. His co-conspirator Walter Belger will carry on the Gigatron mission, including joining us for a Hack Chat on June 24. In the meantime, this might be a great time to pick up a Gigatron kit before they’re all sold out and get busy soldering all those delicious through-hole TTL chips. May of 2020 is the mo...

Homebrew 68K Micro-ATX Computer Runs Its Own OS

-

We’re no stranger to home built Motorola 68000 computers here at Hackaday, but more often than not, they tend to be an experiment in retro minimalism. The venerable processor is usually joined by only a handful of components, and there’s an excellent chance they’ll have taken up residence on a piece of perfboard. Then [NotArtyom] sent in his Blitz , and launched the bar into the stratosphere. Make no mistake, the Blitz isn’t just some simple demo of classic chips. The open hardware motherboard has onboard floppy, IDE, and PS/2 interfaces, with a trio of 8-bit ISA expansion slots for good measure. The  Motorola 68030 CPU is humming along at 50 MHz, with 4 MB of RAM and 512 KB of ROM along for the ride. Designed to fit the Micro-ATX motherboard standard, you can even mount the Blitz in a contemporary PC case and run it on a standard ATX power supply. An earlier prototype of the Blitz motherboard. As if the hardware wasn’t impressive enough, [NotArtyom] went ahead and created hi...
