Getting retro hardware up and running again is sometimes a feat, and the amount of effort needed tends to go up exponentially with increased hardware age. Getting an IDE hard drive running again is one thing, but things like peripherals on truly “retro” computers like Commodores and Amigas is another beast altogether if you even have a 30-year-old mouse still lying around. That’s why adapters like Project mouSTer are here to help you connect modern USB hardware to truly ancient computers.

This piece of equipment was built for the Atari ST (hence the name), an 8-bit computer from the mid-80s. It mates a DB9 plug with USB via a small microcontroller which does the translating. The firmware can be flashed over the USB connection so there’s planned support for other machines of this vintage. The chip supports all the features the original mouse did, too, including PS4 pad support and support for joysticks, and comes in an impressively tiny package once assembled which blends in seamlessly.

The project is a great step to getting retro computers working again, even if you can’t find exact OEM replacements anymore. That’s a common problem, and we’ve seen this solved in other ways for other old Ataris. It’s not uncommon to put modern power supplies in retro computers, either, as long as they power up and work after everything’s wired together.

This year, [Thomas]’ neighborhood has gone from a quiet burg to a bustling lane full of families and children who go out walking for exercise and a change of scenery. Early on, a game emerged to distract children from the pandemic by turning these walks into bear hunts — that is, looking for stuffed bears sitting in the windows of houses and keeping count of them.

With no stuffed bears in the house, he decided to join in the fun by pasting up a 2D panda bear in the window that’s cute enough to calm anyone’s nerves. That was fun for a while, but then he turned it up to eleven by making an interactive 3D version named Bubbles the Bear that blows bubbles and speaks in a friendly voice.

Bubbles sits in a second-story window and waits for passers-by to press one of the buttons mounted on the utility pole below. Both buttons are wired to a 433MHz remote that sends a signal to an ESP32 in Bubbles’ habitat that says it’s time to perform.

We particularly like the bubble maker that [Thomas] designed, which aims a blower fan with an air concentrator at a carousel of 3D printed bubble wands. Both the fan and the carousel can be controlled with a custom web app, and he gets an email every time Bubbles has a visitor that tells him how much bubble liquid is left. Check out the fun-size demo after the break.

Bubbles are fun, especially if you can make them in extremely large quantities. Bubbles can also do work — remember this next time you need a random number generator.

Grand venues of spectacle to entertain audiences has long been a part of history, but such tradition is highly problematic at the moment in the light of the pandemic. Some sports leagues are testing the waters with a soft restart by playing only to a broadcast audience, leaving the stadium empty. Many experiments are in progress trying to liven up an empty stadium and this is where SoftBank saw an opportunity: as a multinational conglomerate that has both a baseball team and a robotics division, they called a team of robots to cheer-leading duty.

Some clips of the cheerleading squad in action have started circulating. A few people may greet the sight with an indifferent shrug, but most tend to fall to an extreme: either finding them hilarious or react with horror. It is only natural to have a strong reaction to such a jarring sight.

Spot was only available for sale recently, and we admit this was not the type of task that came to our minds. Pepper has a longer track record and this is not Pepper’s first baseball game. The humanoid robot has been around long enough to raise questions about a robot’s role in society from unionization to sex work. We haven’t made much progress answering those questions, and now we have even more questions that the lightweight SoftBank Robotics press release (in Japanese) didn’t try to answer.

When people fret about “robots taking our jobs” the conversation doesn’t usually involve sports team cheerleaders, yet here we are. Welcome to the future.

There has been an argument raging for years over whether you should design circuit boards with 45-degree corners or 90-degree corners. Why make them with corners at all? This breathtaking circuit board art is from a digital watch circa 1975.

The Pulsar Calculator Watch was the first of its kind and came along with a stylus to operate the miniscule buttons. The circuit board traces would have been laid out by hand, explaining the gentle curves rather than straight lines. The chip-on-board construction is wild, with the silicon die bonded directly to those traces on multiple chips in this image. There is also a mercury tilt sensor on this model that would have switched the display off when not being held up to view the time (or calculate your tip at the Ritz).

We found working models of this watch for sale online for about $225-350. That’s a steal considering the original list price for these is reported to be $550 ($2600 considering inflation).

The beauty of the PCB artwork is hidden away, not just inside the watch case, but obscured by the plastic battery housing to which those tabs on the right are soldered. Think of how many geeks were lucky enough to have one of these and never realized the beauty within. If you’re looking to unlock more of these hidden masterpieces, check out [Greg Charvat’s] article on collecting and restoring digital wristwatches.

Custom weather stations are a common enough project these days, especially based around the ESP8266. Wire a sensor up to the MCU, power it up with an old phone charger, and you’re half way there. But if you want something that’s going to operate remotely on the long term, you’ve got to put a little more thought into it.

Which is exactly what [BuckarewBanzai] did for his solar powered Raspberry Pi weather station. With an industrial NEMA-rated enclosure, a beefy 35 watt photovoltaic panel, and enough lead-acid battery capacity to keep the show going for days, this build is certainly more robust than most. Some might call it overkill, but we think anyone who’s ever deployed hardware outdoors for more than a few days knows you can never be too careful when Mother Nature is involved.

To keep the 18 Ah battery topped off, [BuckarewBanzai] is using a 10 amp Wanderer charge controller. It sounds as though he burned through a few lesser models before settling on this one; something to consider for your own off-grid projects. An LM2596 regulator is then used to provide a stable 5 V for the Raspberry Pi.

In addition to the BME280 environmental sensor that picks up on temperature, humidity, and pressure, there’s also a AS3935 lightning sensor onboard which [BuckarewBanzai] says can pick up strikes up to 40 kilometers away. All of this environmental data is collected and stored in a local SQLite database, and gets pushed offsite every five minutes with a REST API so it can be visualized with Grafana.

Critics in the audience will no doubt pick up on the solderless breadboard located in the center of the weather station, but [BuckarewBanzai] says he’s already on the case. He’s working on a custom PCB that will accept the various modular components. Not only should this make the station more reliable, but he says it will cut down on the “spaghetti” wiring. Though for the record, this is hardly the worst offender we’ve seen in that department.

When starting out on a project, it’s accepted best practice to try to avoid feature creep. Of course, we can’t all say that we follow this guideline completely every time. In fact, sometimes it can get away from us, and in rare situations it might actually turn out pretty well. That appears to be what happened with [superczar]’s home automation project which now covers basically everything possible in home automation.

The build started in 2013, so we assume that features have been added periodically and that the system wasn’t designed and built all in one furious weekend. Either way, though, it covers a lot: lights, switches, media players in several rooms, includes sensors and logging for temperature, smoke, fire, and power, supports a number of cameras, the doorbell, and the locks. It also includes voice control for most of the systems.

That’s an impressive list, but what really drew our attention to this project is that it used to be based on domoticz, but that community has waned over the years and [superczar] had kept his system patched together with self-built scripts. An accidental upgrade recently broke the entire setup, so rather than rebuild everything a migration was made to home-assistant, an open-source platform that has a more active community. We’ve seen plenty of projects around here that use it as a platform, for ceiling fans, custom remotes, and doorbells.

Analog Devices will acquire Maxim Integrated for $20.9 billion dollars in stock, as reported by Bloomberg this morning.

Perhaps the confusing part of the news is that the Bloomberg article mentions the acquisition will let Analog Devices better compete with Texas Instruments. Wait, didn’t Texas Instruments acquire Maxim back in 2015? Actually, no. There were rumors (reported then by Bloomberg) that TI was nearing an acquisition deal but it fell through in January of 2016.

You may remember that Analog Devices snapped up Linear Tech in a $30 B acquisition back in 2017. Considering this morning’s news, how will they compare to the might of TI? Looks like 2019 revenue for TI was $14.38 B while Analog reported $5.99 B. Add in Maxim’s revenue of $3.1 B and there’s still a David and Goliath scenario here. Although revenue doesn’t tell the whole story and the proverbial slingshot for Analog may be its existing portfolio of high-margin devices, grown even larger with this acquisition.

Considering how the last half decade played out, this might mark the beginning of another wild cycle of mergers and acquisitions. The consolidation trend continues as we approach a world where just a few gigantic semiconductor companies turn production lines up to eleven to fill the world’s insatiable appetite for more powerful electronics (and more electronics in general).
