When it was launched in 2013, the BladeRF was one of the most powerful of the new generation of Software Defined Radios. Now, Nuand, the producers of the BladeRF are looking to up the ante again with the BladeRF 2.0 Micro. This new version has a huge list of changes and improvements, including a more bad-ass FPGA processor and support for receiving and transmitting from 47 MHz all the way up to 6 GHz, with 2x MIMO support and an impressive 56 Mhz of bandwidth. It also retains backwards compatibility with the original BladeRF, meaning that any software written to support it (which most SDR packages do) will just work with the new device.
[Bill Meara] has discovered an easy way to listen to amateur “cube-sat” satellites using a cheap SDR Dongle.
The DVB-T SDR Dongle comes in at a whopping thirteen bucks, and the highly sophisticated antenna (pdf) is made from a bit of copper wire and uses aluminum wire for the ground plane.
Once he had everything hooked up, [Bill] went to the Heavens Above website to see when satellites would be passing over him. He was able to lock onto the Prism Satellite, and then a couple other cube-sats that were launched from Russia and Istanbul.
It hasn’t become a household term yet, but Software-Defined Radio (SDR) is a major player on the developing technology front. Whether you’re building products for mass consumption, or just playing around for fun, SDR is worth knowing something about and I’ll prove it to you.
If you haven’t backed PortableSDR on Kickstarter, now’s the time to do it. [Michael Colton’s] project which frees a Software Defined Radio from being shackled to a computer is in the final three days and needs about $17,500 to make it.
We’d really like to see this one succeed, and not just because PortableSDR took 3rd place in the 2014 Hackaday Prize. Many a time we’ve heard people forecast the death of amateur radio (ham if you will). The ham community is special, it’s a great way to get mentorship in electronics, and deals in more than just digital circuitry. Plus, as [Greg] has pointed out, having a license and some know-how lets you build and operate really powerful stuff!
We see the PortableSDR as one way to renew interest in the hobby. We especially like it that you don’t need a license to operate the basic model — the transmitting circuits aren’t enabled when it arrives. This means you can learn about SDR, explore what’s going on over the airwaves, and only then take the leap by applying for your license and hack the unit to transmit. To be fair, the transmitter portion of the project hasn’t been published yet, which is about the only real concern we read in the Kickstarter comments. But we have faith that [Michael] will come through with that part of it. And if he needs help we’re sure he’ll have no problem finding it.
Now’s the time… let’s pull this one out in the final days!
Last year’s Hackaday Prize saw a lot of projects that were crying out to be Kickstarter Campaigns, but non has seen people throwing money at their screens quite like [Michael]’s PortableSDR. It’s a small, handheld, battery-powered shortwave software defined transceiver that can do just about everything with coverage up to 30MHz. It’s the ultimate apocalypse radio, a contender for to the throne now held by the ‘my first radio’ Baofeng, and now, finally, a campaign on Kickstarter.
The PortableSDR (now called the PSDR) started off as [Michael]’s ideal radio. It just so happened the Hackaday Prize gave him the impetus design, develop, and build the radio that would eventually land him third place in The Hackaday Prize.
The radio itself is completely self-contained and battery-powered, implementing a software defined radio on an STM32F4 processor. The design includes an LCD for the waterfall display, vector network analysis, and the ability to receive GPS.
In keeping with its ham heritage, [Michael] is offering the PSDR as a kit, with a PCB, enclosure, and all the parts you can’t get on Digikey available for a $250 pledge. Get those toaster reflow ovens warm, because there’s a lot of SMD parts in this build.
No other project to make it to The Hackaday Prize has people throwing money at their computer screen hoping something would happen than [Michael Colton]’s PortableSDR. It’s a software defined radio designed for coverage up to 30MHz. Amateur radio operators across the world are interested in this project, going so far as to call this the first Baofeng UV-5R killer. That’s extremely high praise.
[Michael] was kind enough to sit down and answer a few questions about how his entry to The Hackaday Prize has gone. You can check that out below, along with the final round video of the project. Anyone who wants their own PortableSDR could really help [Michael] out by taking this survey.
It’s been a long road for each of the five finalists; but after tonight they can breathe easy. The last judging round of the 2014 Hackaday Prize begins at 11:50pm PDT.
Each finalist must finish documenting their project by that time as a cached version of each of the project pages will be sent off to our orbital judges. Joining the panel that judged the semifinal round is [Chris Anderson], CEO of 3D Robotics, founder of DIY Drones, former Editor-in-Chief of Wired, and technology visionary. These nine are charged with deciding who has built a project cool enough to go to space.
In case you’ve forgotten, the final five projects selected by our team of launch judges are:
- ChipWhisperer, an embedded hardware security research device for hardware penetration testing.
- Open Source Science Tricorder, a realization of science fiction technology made possible by today’s electronics hardware advances.
- PortableSDR, is a compact Software Defined Radio module that was originally designed for Ham Radio operators.
- ramanPi, a 3D printed Raman Spectrometer built around a Raspberry Pi.
- SatNOGS, a global network of satellite ground stations.
The ultimate results of the judging will be revealed at The Hackaday Prize party we’re holding in Munich during Electronica 2014. We’re also holding an Embedded Hardware Workshop with Moog synths, robots, hacked routers, computer vision, and a name that’s official-sounding enough to convince your boss to give you the day off work. We hope to see you there!
