Probe the Galaxy on a Shoestring with this DIY Hydrogen-Line Telescope

Foil-lined foam insulation board, scraps of lumber, and a paint-thinner can hardly sound like the tools of a radio astronomer. But when coupled with an SDR, a couple of amplifiers, and a fair amount of trial-and-error tweaking, it’s possible to build your own hydrogen-line radio telescope and use it to …read more

3D Printed VirtuScope is a Raspberry Pi 4 Cyberdeck with a Purpose

William Gibson might have come up with the idea for the cyberdeck in 1984, but it’s only recently that technology like desktop 3D printing and powerful single board computers have enabled hackers and makers to assemble their own functional versions of these classic cyberpunk devices. Often the final product is …read more

Cheap Sensors and an SDR Monitor Conditions in this Filament Drying Farm

We don’t know where [Scott M. Baker] calls home, but it must be a pretty humid place indeed. After all, he has invested quite a bit in fancy vacuum storage containers to keep his 3D-printer filament dry, with the result being this sensor-laden filament drying farm.

[Scott] wasn’t content to …read more

Side-Channel Attack Shows Vulnerabilities of Cryptocurrency Wallets

What’s in your crypto wallet? The simple answer should be fat stacks of Bitcoin or Ethereum and little more. But if you use a hardware cryptocurrency wallet, you may be carrying around a bit fat vulnerability, too.

At the 35C3 conference last year, [Thomas Roth], [Josh Datko], and [Dmitry Nedospasov] …read more

Drone on Drone Warfare, With Jammers

After the alleged drone attacks on London Gatwick airport in 2018 we’ve been on the look out for effective countermeasures against these rogue drone operators. An interesting solution has been created by [Ogün Levent] in Turkey and is briefly documented on in his Dronesense page on Crowdsupply. There’s a few …read more

A Briefcase Pentesting Rig For The Discerning Hacker

In the movies, the most-high tech stuff is always built into a briefcase. It doesn’t whether whether it’s some spy gear or the command and control system for a orbiting weapons platform; when an ordinary-looking briefcase is opened up and there’s an LCD display in the top half, you know …read more

An SDR Transceiver The Old-School Way

Software-defined radios or SDRs have provided a step-change in the way we use radio. From your FM broadcast receiver which very likely now has single-application SDR technology embedded in a chip through to the all-singing-all-dancing general purpose SDR you’d find on an experimenter’s bench, control over signal processing has moved …read more

Pluto (SDR) Goes Ethernet

Pluto may no longer be a planet, but it is still a fun software defined radio (SDR) set up from Analog Devices. The inexpensive radio uses a USB connector and looks somewhat like a network connection to your PC. But what if you want to really use it with a …read more

Full Earth Disc Images From GOES-17 Harvested By SDR

We’ve seen lots of hacks about capturing weather images from the satellites whizzing over our heads, but this nicely written how-to from [Eric Sorensen] takes a different approach. Rather than capturing images from polar satellites that pass overhead a few times a day, this article looks at capturing images from …read more
