Doom is now running on the ESP32. This is some work from [Sprite_tm], and the last we heard about Doom on the ESP32 is that there was a silicon bug or something. Now we’re knee deep in the dead on a tiny WiFi and Bluetooth-enabled microcontroller.

Loading animations have a long and storied history. What originally began as an hourglass quickly turned into a hand counting to five and progress bars. There were clocks, the Great Beach Ball of Death, and now loading animations are everywhere. However, the loading animation has still not been perfected — until now, that is. This is a fidget spinner loading animation. It’s beautiful.

Just a quick reminder that a Minecraft scholarship exists. Yeah, I know what you’re thinking, but there is a scholarship from the Klingon Language Institute for studying any language, and last year’s winner built a redstone computer from scratch,

[8bit generation] recently released a documentary, about the rise of Atari. Easy to Learn, Hard to Master is about the rise of Atari under [Nolan Bushnell]. Now [8bit generation] is working on a new documentary: Firing Steve Jobs. The [Steve Jobs] story is fascinating, and no matter what you think of him, he probably knew what he was doing.

Want to build and sell some hardware? Over on Tindie, we’re taking a look at some of the most successful designers of custom crafted hardware. This time it’s [Albertas Mickėnas] of Catnip Electronics who has sold five thousand soil moisture sensors.

You can just go out and buy a CNC machine, but that doesn’t quite underscore the difficulty in getting a CNC machine running. Our ‘ol pal [Jeremy] recently picked up a Romaxx CNC machine and put together a video of its commissioning. There’s a lot of work here, from building a shelf/stand for a rather beefy machine to cutting into the bed for t-tracks, and figuring out how dust collection is going to happen.

Before there was KiCad and Eagle and a ton of web-based PCB design tools, there was Autotrax. Want to know what PCB design and GUIs look like in DOS? I did a walkthrough for designing a small PCB in the DOS version of Autotrax late last year. There are thousands of designs locked up in discontinued EDA suites, and [Erich] has a way to revive them. He’s developed an Autotrax/Easytrax layout import/export plugin for pcb-nd. Now legacy Protel designs can be imported into software released in this century. This is really cool, and you can check out some screenshots here.

Creating A PCB In Everything: Protel Autotrax

Protel Autotrax is a PCB design tool first released for DOS in the mid-80s. Consider this a look at the history of PCB design software. I’m not recommending anyone actually use Protel Autotrax —  better tools with better support exist. But it’s important to know where we came from to understand the EDA tools available now. I’m rolling up my sleeves (about 30 years worth of rolling) and building our standardized test PCB with the tool. Beyond this, I suggest viewing EEVblog #747, where [Dave] digs into one of his old project, Borland Pascal, and Protel Autotrax.

This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. We’ve already covered Eagle in this series. We learned Fritzing is a joke for PCB design, although it is quite good for making breadboard graphics of circuits. Each of these tutorials serves as a very quick introduction to a specific PCB design tool. Overall, this series provides for a comparison between different PCB design tools. Let’s dig into Protel Autotrax.

A short history of Protel, Altium, and Autotrax

The company we know as Altium today was, for the first fifteen years of its existence, known as Protel. Back in the day, PCB design on a computer required a dedicated workstation, a lot of hardware, light pens, and everything was extraordinarily expensive. Protel was a reaction to this and the first product, Autotrax, was a DOS-based program that brought PCB design to the PC. A freeware version of Autotrax is still available on the Altium website and can be run from inside a DOS virtual machine or DOSBox.

Interestingly, Protel Autotrax is not the only PCB design software named Autotrax. A company called DEX 2020 has also has a PCB design software called AutoTRAX. This is weird, confusing, and I can’t figure out how this doesn’t violate a trademark. If anyone has any insight to what the Protel / Altium legal department was doing a few decades ago, your wisdom is welcome in the comments.
