New Raspberry Pi Zero 2 Upgrades To Quad-Core Processor

Over the years, we’ve seen a steady stream of updates for the Raspberry Pi Foundation’s flagship single-board computer (SBC), with each new release representing a significant boost in processing power and capability. But the slim Raspberry Pi Zero, released all the way back in 2015, hasn’t been quite so fortunate. Beyond the “W” revision that added WiFi and Bluetooth in 2017, the specs of the diminutive board have remained unchanged since its release.

That is, until now. With the introduction of the $15 USD Raspberry Pi Zero 2 W, the ultra-compact Linux board gets a much-needed performance bump thanks to the new RP3A0 system-in-package, which combines a Broadcom BCM2710A1 die with 512 MB of LPDDR2 SDRAM and a quad-core 64-bit ARM Cortex-A53 CPU clocked at 1 GHz. In practical terms, the Raspberry Pi Foundation says the new Zero 2 is five times as fast as its predecessor with multi-threaded workloads, and offers a healthy 40% improvement in single-threaded performance. That puts it about on par with the Raspberry Pi 3, though with only half the RAM.

Otherwise, the new Zero 2 isn’t much different from the original. It’s the same size and shape, meaning existing cases or mounts should work fine. You’ll also find the micro SD slot, CSI camera connector, dual micro USB ports, and mini HDMI port in the same places they were in 2015.

Frankly we’re a little surprised they didn’t switch over to USB-C (at least for the power port) and micro HDMI to bring it in line with the Pi 4, but of course, they presumably didn’t want to break compatibility with existing Zero projects. At least we won’t have to wait for a second edition to add wireless, as the Zero 2 W offers 2.4 GHz 802.11 b/g/n WiFi and Bluetooth 4.2 out of the box.

We’ll have samples of the new Zero 2 W in hand shortly, so keep an eye out for a detailed overview of this highly anticipated new member of the Pi family. In the meantime, let us know what you think about the new hardware in the comments. Is it a worthy successor to the original $5 Pi Zero?

Lockheed Shares Satellite Connectivity Options

In an unusual turn of events, Lockheed Martin has released technical “payload accommodation information” for three of their satellite busses. In layperson’s terms, if you wanted to build a satellite and weren’t sure what guidelines to follow these documents may help you learn if Lockheed Martin has a platform to help you build it.

An opportunity to check out once-confidential information about satellites sounds like a perfect excuse to dig through some juicy documentation, though unfortunately this may not be the bonanza of technical tidbits the Hackaday reader is looking for. Past the slick diagrams of typical satellites in rocket fairings, the three documents in question primarily provide broad guidance. There are notes about maximum power ratings, mass and volume guidelines, available orbits, and the like. Communication bus options are varied; there aren’t 1000BASE-T Ethernet drops but multiply redundant MIL-STD-1553B might come standard, plus telemetry options for analog, serial, and other data sources up to 100 Mbps. Somewhat more usual (compared to your average PIC32 datasheet) are specifications for radiation shielding and it’s effectiveness.

In the press release EVP [Rick Ambrose] says “we’re sharing details about the kinds of payloads we can fly…” and that’s exactly what these documents give us. Physical ballpark and general guidelines about what general types of thing Lockheed has capability to build launch. Hopefully the spirit of openness will lead to the hoped-for increase in space utilization.

If you take Lockheed up on their offer of satellite development, don’t forget to drop us a tip!

SatNOGS Wins The 2014 Hackaday Prize

The Grand Prize winner of the 2014 Hackaday Prize is SatNOGs. The project is a thrilling example of the benefits of a connected world. It opens up the use of satellite data to a much wider range of humanity by providing plans to build satellite tracking stations, and a protocol and framework to share the satellite data with those that cannot afford, or lack the skills to build their own tracking station. The hardware itself is based on readily available materials, commodity electronics, and just a bit of 3D printing.

The awarding of the Grand Prize caps off six-months of productive competition which started in April with a first round reaching to more than 800 entries. Once the field had been narrowed and sent on to our judges the narrowed it to just 50 projects vying for a trip into space (the grand prize), industrial-grade 3D printer and milling machine, a trip to Akihabara electronics district in Japan, and team skydiving.

Congratulations to all 5 top winners

 

SatNOGS – Grand Prize

You already know this but such an accomplishment is well worth mentioning again!

ChipWhisperer – Second Prize

KONICA MINOLTA DIGITAL CAMERA

The ChipWhisperer is a hardware security testing platform that allows developers to explore side-band and glitch vulnerabilities in their hardware projects. The existing technologies for this type of testing are prohibitively expensive for most products. The availability of this tool plays a dual role of helping to inform developers of these potential attack vectors, and allowing them to do some level of testing for them.

PortableSDR – Third Prize

hardware-in-use

The form and function of the PortableSDR move forward both Software Defined Radio and Ham. The SDR aspect fully removes the need to use a computer. The wireless functions provided can be called a modernization of portable amateur radio hardware.

Open Source Science Tricorder – Fourth Prize

tricorder-interface

Inspired by the future-tech item found in the Star Trek franchise, the Open Source Science Tricorder uses currently available technology to produce a handheld collection of sensors. The design provides modularity so that the available sensors can be customized based on need. Equally importantly, the user interface gives meaning to the data being measured, and allows it to be uploaded, graphed, and otherwise manipulated on the Internet.

ramanPi – Fifth Prize

ramanPi

Raman Spectroscopy is used to help determine what molucules are found in test samples. One example would be determining possible contaminants in drinking water. These tools are expensive and the ramanPi project will mean more labs (at University or otherwise) as well as citizen scientists will be able to build their own spectrometer. One particularly interesting aspect of the project is the parametric 3D printer file used for mounting the machine’s optics. The use of this technique means that the design can easily be adapted for different types of lenses.

2015 Hackaday Prize

Goodbye Hackaday, I’ll Miss You.

Farewell Hackaday, the time has come for me to move on. Don’t worry, hackaday will keep going, just like it did when [Eliot] moved on, and [Phil] before him.

I wrote my first post on July 9th, 2008. Since then I’ve had so much fun, and written a total of 1,552 posts (including this one). In my opinion, there is simply no other site like Hackaday.com, our readers are passionate and knowledgeable and it shows, even if some of you are incredibly rude to each other(that’s a sign of passion right?).

While some projects stand out in my mind, it is the people I have enjoyed the most. The people I met when I went to all the different hackerspaces, my co-writers[Mike Szczys] and[Brian Benchoff], past hackaday employees, our commenters,  and even my boss [Jason Calacanis].

If you want to find me, I’ll be at calebkraft.com or on facebook or G+. I have a twitter too, that I guess I’ll start using today.

Join me after the break just one more time while a take a trip down memory lane with a few of my favorite moments from the last few years.  Oh, and yes, I think saying “after the break” is stupid. What else do you say though?

2012 Open 7400 Logic Competition

The Open 7400 Logic Competition is being held again this year. Start thinking about your entries, they’ll need to be finished and submitted by October 31st. As motivation, Digilent has put up two of their Analog Discovery kits as prizes. They can be used as a dual channel oscilloscope, function generator, or 16-channel logic analyzer. Last year was the first time the competition was held. As hype for the event built, more and more prize sponsors signed on and we hope to see the same thing happen this year.

Your entry can be just about anything as long as you show your schematic, explain the project, and use logic. It can be 7400 TTL, 4000 CMOS, discrete gates, or even a CPLD. Last year’s entries spanned a wide range of themes from LED blinkers, to unorthodox 74xx chip hacking, to boards packed full of chips. Good luck and don’t forget to tip us off about your work!

[Thanks Adrian]
