Проектируем процессор постапокалипсиса с помощью openSource

Проектируемый компьютер на сверхминиатюрных электронных лампах хоть и является радиационно-стойким, однако работает на электричестве. Кроме того, восстановить в сжатые сроки производство электронных ламп в условиях постапокалипсиса будет довольно сложной задачей. На руинах цивилизации гораздо проще организовать массовое производство логических элементов, работающих на эффекте прилипания струи воздуха к стенке — при этом сам элемент можно лепить хоть из глины! И мало того, что для создания потока воздуха не обязательно использовать электричество — теоретически такой процессор сможет работать на энергии ударной волны ядерного взрыва! Но обо всём по порядку. Для тех, кто следит за проектом DekatronPC — не пугайтесь, ему ничего не...

In the Wild: Netflix Open Connect – CFA635

Recently, a Reddit post came to our attention in which someone had an old Netflix server, and on the face of that server was an awfully familiar keypad. Commenters confirmed in the thread that it is a CFA635.

We had to look into it more and find out if there was more information about these servers! On the Open Connect home page, there was a photo of a whole rack full of servers with CFA635s!

Have you spotted our keypads in the wild? Send us a photo, we’d love to see it!

We offer many great LCD options that...

Packetry Preview

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/packetry-preview

Due to the delays caused by the chip shortage, there’s not been a lot to report on the LUNA hardware front recently – but behind the scenes, we’ve been hard at work on the software stack which will accompany it. Over the next few weeks, we’ll be making some more updates about that work.

One of LUNA’s key features is its ability to act as a passive sniffer: it can be connected between a computer and the USB devices connected to it, capturing all the traffic between them. This...

Free Stuff - September 2022

The September recipient for the Great Scott Gadgets Free Stuff Program is Brett! Brett volunteers at the Wasatch 100 in Utah. The Wasatch 100 is a 100 mile endurance run through the Wasatch National Forest. Brett is planning to use the HackRF One we are sending him to streamline the race aid station communications. We look forward to seeing the solution he comes up with.

OsmoDevCall: "Osmocom SIMtrace2 Tutorial"

I've presented an SIMtrace2 Tutorial - SIM protocol tracing: how and why as part of the OsmoDevCall talk series on Osmocom and related technology.

InfiniTime 1.11

We released InfiniTime 1.11 a few days ago. The timing of the release did not align with the monthly community update, so we decided to write a small blog post to highlight a few new features and provide new about the PineTime community!

October update: An Ox, no bull

I hope that the good news and all the announcements of this month will make up for the much delayed publication date - which is something I sincerely apologize for.

CFA632 and CFA634 Custom Characters

We recently received a question about setting custom characters on our CFA632 and CFA634 modules.

The datasheet includes an example of using custom characters which looks like this:

\012\001\128\129\130\131\017\000\001\132\133\134\135
\025\000\000\000\001\003\000\031\031\031
\025\001\028\054\032\001\003\051\051\051
\025\002\014\027\049\032\032\047\032\047
\025\003\000\000\032\048\000\062\000\062
\025\004\031\031\031\000\003\001\000\000
\025\005\051\051\051\003\001\032\054\028
\025\006\047\032\047\032\032\049\027\014
\025\007\062\000\062\000\048\032\000\000

The customer wanted to know what was going on and what would the custom characters look like.

1. The example is in decimal rather than hexadecimal, so the lines that start with \025 are the custom character setting lines.

2.  I’m not sure why the first line was put first rather than last, but it’s showing the custom characters in action. If you have a CFA632 with the...

Introducing Opera Cake

Starting this week, we are shipping Opera Cake, our multi-use antenna-switching add-on for HackRF One!

This add-on board has two primary ports, each connected to any of eight secondary ports, and it is optimized for use as a pair of 1x4 switches or as a single 1x8 switch.

As a 1x8 switch, Opera Cake can connect your HackRF to a variety of antennas at once, such as a long wire antenna for HF bands, a discone for VHF and UHF, a dipole for 2.4 GHz, and a dish for a satellite band. Once connected to your Opera Cake you can switch between...

Pseudo-Doppler Redux, ShmooCon 2018

https://www.youtube-nocookie.com/embed/6wF6g2f8aIQ

Back in 2018 Michael Ossmann teamed up with Schuyler St. Leger at ShmooCon to present “Pseudo-Doppler Redux”; a talk about taking a modern approach to the implementation of pseudo-doppler direction finding (DF) with Software Defined Radio (SDR). This presentation demonstrates what pseudo-doppler direction finding is and gives an example of Opera Cake usage.

We hope you enjoy watching the presentation!
