“They paved paradise and put up a parking lot.” That might be stretching things a bit, especially when the “paradise” in question is in New Jersey, but there’s a move afoot to redevelop the site of the original “Big Bang Antenna” that has some people pretty upset. Known simply as “The Horn Antenna” since it was built by Bell Labs in 1959 atop a hill in Holmdel, New Jersey, the antenna was originally designed to study long-distance microwave communications. But in 1964, Bell Labs researchers Arno Penzias and Robert Wilson accidentally discovered the microwave remnants of the Big Bang, the cosmic background radiation, using the antenna, earning it a place in scientific history. So far, the only action taken by the township committee has been to authorize a study to look into whether the site should be redeveloped. But the fact that the site is one of the highest points in Monmouth County with sweeping views of Manhattan has some people wondering what’s really on tap for the site. A petition to save the antenna currently has about 3,400 signatures, so you might want to check that out — after all, you don’t know what you’ve got ’til it’s gone.

Aerodox Flies on Wireless Wings

Aerodox, a wireless, split keyboard.[Simon Merrett] didn’t know anything about keyboards when he started this project, but he didn’t let that stop him. [Simon] did what any of us would do — figure out what you like, learn enough to be dangerous, and then start fiddling around, taking all that inspiration and making a mashup of influences that suits your needs.

The Aerodox design became a cross between the ErgoDox‘s key layout and the logic and communication of the Redox Wireless, itself a reduced-size version of the ErgoDox. Interestingly, [Simon] chose the ErgoDox’s dimensions and spacing, and not those of the Redox. Like a lot of people out there, I found the ErgoDox to be too big for my hands, mostly in that the thumb cluster is too far away from the mainland. It’s nice to see that it suits some people, though.

[Simon] worked up a custom hot-swap footprint that makes the board reversible, much like the ErgoDox. Each half has an NRF51822 for a brain, and there’s a third one that acts as a receiver. This external NRF board is connected over UART to an Arduino Pro Micro, which acts as the USB HID and runs QMK. It’s an interesting journey for sure, so go dig into the logs.

There are a bunch of newly minted millionaires this week, after it was announced that Stack OverFlow would be acquired for $1.8 billion by European tech investment firm Prosus. While not exactly a household name, Prosus is a big player in the Chinese tech scene, where it has about a 30% stake in Chinese internet company Tencent. They trimmed their holdings in the company a bit recently, raising $15 billion in cash, which we assume will be used to fund the SO purchase. As with all such changes, there’s considerable angst out in the community about how this could impact everyone’s favorite coding help site. The SO leadership are all adamant that nothing will change, but only time will tell.
