The March recipient for the Great Scott Gadgets Free Stuff Program is Katerina Autumnrain! Katerina had such an enthusiastic and detailed application to the Free Stuff Program that we just had to send her the HackRF One she requested. In her application she had this to say:

“I believe that the HackRF could enable me to open up the oft more confusing aspects of radio, particularly modulation modes like QAM and digital systems like satellites and P25/DMR. I’d also like to try and promote the higher frequencies (33cm and beyond). Once the bandwidth and frequency limitation is lifted I can more or less apply that knowledge I’d gain from those systems and make both learning experiences and some pretty neat tech for people to explore, utilize, and build themselves. I ultimately believe I could cultivate a sort of resurgence in radio geekery in my area, as it unfortunately seems to be on the downturn somewhat, and promote higher levels of curiosity.”

It’ll be really exciting to follow Katerina’s updates on her HackRF-fueled radio journey!

Drumroll, please! The free stuff recipients for January and February were:

Rushabh Vyas, who is a graduate student at the Purdue School of Engineering and Technology, IUPUI, is receiving four LAN Tap Throwing Star kits for use in his digital escape room projects and in his cybersecurity group, TheDen.

His current forensics class is using a bomb-defusal scenario. He reports: “End goal for the forensics students is to be able to get access to Arduino code (by completing various forensics tasks such as steganalysis, data decoding, and artifact analysis), analyze the code, and be able to cut the correct colored wire for defusal in ~60 minutes.”

We sent a HackRF One to the University of Toronto Aerospace Team, Space Systems Division. They are a team of 40 undergraduates who are working on an open source CubeSat for carrying out microbiology experiments in space! Their first satellite, HeronMk II, is slated to launch in early 2020.

One of their team leads, Siddarth Mahendraker, tells us:

“We plan to use the HackRF to build a programmatic interface to our radio communications system, in conjunction with GNURadio. This will make it significantly easier for us to test our on-board computer systems, downlink payload data, and integrate and test additional satellite subsystems”

HERON Mk II is a 3U Cubesat designed and built by the Space Systems division of the University of Toronto Aerospace Team to perform sophisticated microbiology experiments in orbit. The organism of interest is C. Albicans, a yeast that is commonly found in the human gut flora that may undergo changes in its virulence and drug resistance when experiencing microgravity.

Here is their website:

We also gave away two HackRF Ones in February:

One went to Brian Granby, a PhD student at Liverpool John Moores University. He is doing security research, conducting a study into emerging sensors technologies; with a particular focus surrounding network security of RF connected devices. His main focus is on the potential threats of residential and commercial gas supplier technologies found in smart meters.

The other we are sending to Sudip Kar of Bangalore. He is going to use his HackRF One to introduce SDR to small village schools by helping them to set up their own weather stations that can track NOAA satellites. He is going to send us pictures after the students finish their year-end exams and start using the HackRF later this spring.

In 2017, we read a whole bunch of requests for free stuff, and we were really impressed with the many excellent submissions we received. Since our last free stuff update, we have given away 16 HackRFs and several Throwing Star LAN Tap Kits to researchers, makerspaces, amateur radio groups, and educators. The 2017 free stuff receipients included:

• Dr. Fernando Pena Campos — HackRF One for wireless communications education at the university undergraduate level
• New Hampshire Hacker's Association (NEHA) meetup — HackRF One for SDR workshops
• Reforge Charleston — Throwing Star LAN Tap Kits and a HackRF One for an education based non-profit makerspace
• Cal Poly Amateur Radio Club — HackRF One (with a Clear Acrylic Case) for the equipment shack (special thanks for the T-shirts!)
• University of Michigan Rocketry Team — HackRF One (and a Clear Acrylic Case) to help with the development and prototyping of a "from scratch" GPS receiver and other avionics systems
• Fred Pelland — HackRF for an amateur radio group
• Sebastien Mrozek, teacher at Elsa-Brändström-Schule, a secondary school in Elmshorn, Germany — HackRF One for the school's electronics lab
• Juan Moreno, professor at Universidad Politecnica de Madrid — HackRF One to help develop an SDR focused Massive Open Online Course (coming soon: https://miriadax.net/web/software-defined-radio-101-with-rtl-sdr)
• Marco Manzoni/Skyward Environmental Rocketry — HackRF One for use in the development of the RF system of a student-made rocket
• Make Riga Hackerspace — HackRF one to help this hackerspace's members accomplish interesting projects, like "aiming to reach 100km with a large model rocket + balloon (thus their own gps solution), and another member is rolling out his own gsm stack"
• Bill — HackRF One for an SDR workshop given at the New Mexico Hamfest
• Carlos Yero for Abertay University Ethical Hacking Society — HackRF One "to be available to all students working on the Ethical Hacking degree with aim to overcome fear of SDR complexities"
• Fellow open source hardware designer Manuel Domke of 13-37.org — HackRF to use as a spectrum analyzer for EMC product compliance testing

Sometimes, free stuff recipients send us pictures, like this one from Elsa-Brändström-Schule in Germany (we love it when free stuff receipients send us pictures; it increases the general level of warm fuzzies):

We'll be doing more free stuff updates shortly, so check back soon! Also, please keep the free stuff requests coming. For information about how to request free Great Scott Gadgets hardware, please visit the Free Stuff page.

It's been a while since we've posted, but yes, we are still giving away free stuff! Even though we can't respond to each and every email, we do read and carefully consider all of them, and we choose at least one awesome group, project, or individual each month to send some free hardware to. Here are the free stuff recipients for the first half of 2016.

ADS-B Out Open Source Project

We gave a HackRF One to developer and pilot Christopher Young, whose latest development project is an in-flight ADS-B Out transponder. ADS-B Out allows pilots to broadcast position, ground speed, and altitude to air traffic controllers and aircraft that are equipped with ADS-B In. This project benefits general aviation pilots because NextGen, the FAA's new plan to increase aviation safety, mandates that all aircraft be equipped with ADS-B Out by the year 2020. Christopher's open source design is intended give pilots a more affordable means of complying with the new requirement (ADS-B out is a piece of avionics equipment that normally costs thousands of dollars). Chris is also the creator of the stratux project, an affordable open source aviation weather and traffic receiver solution based on low-cost SDRs, so we are excited to put a HackRF into his capable hands.

Visible Light Communication Research

We gave a HackRF One to Alexis Duque, a Phd candidate at INSA in Lyon, France. He is researching the possibilities of visible light communication, and wants to use SDR hardware and GNURadio for some tests. He plans to donate his HackRF to CorteXlab at INSA after the research is complete.

Fablab Hackerspace

We received a free stuff request for a YARD Stick One from Pedro, a high school student at a technical school in southern Brazil who has started a hackerspace called Fablab with a group of his friends. Their school has given them space to work in, but due to equipment costs and crippling taxes imposed on electronics equipment there, they have been unable to find the funds to stock their lab and are relying on donations from the community. We sent them a YARD Stick One so that their group can experiment with communications with a drone they received from a local university.

Argentinian Meetup Group

Speaking of South America, we gave a HackRF to Martin Gallo, coordinator of TandilSec, a meetup group in Tandil, Argentina who discuss infosec topics and learn about current trends. They have recently been experimenting with is SDR, and HackRF One was their hardware of choice.

Qspectrum Analyzer

We gave a HackRF One to the Qspectrumanalyzer open source project because it currently only supports rtl-sdr, and the developer of that program wanted to change that. He tells us that a popular request from users is that they would like to see support for HackRF One.

Amateur Radio Equipment Repair

Pavel is a ham radio operator, self-described tinkerer, and software developer. He is involved with a local amateur radio club, but lives in an area where good radio equipment is difficult to obtain, and the equipment they are able to get their hands on is usually in need of repair. Pavel asked us for a HackRF One to diagnose and test problems, which will help him repair the radio equipment of other amateur radio operators in his community.

Stay tuned; more free stuff updates are on the way! Visit our free stuff page to learn how to submit a request.

The Great Scott Gadgets team has been hard at work sorting through all the Free Stuff requests for 2015, and now we are finally ready to announce the winners for May through December. We've had many interesting submissions, and we've enjoyed learning about all the ideas you have had for open source projects and education. After much discussion and some tough decisions, we've chosen the following seven individuals and groups to receive free hardware from Great Scott Gadgets.

Open Source Project: Universal Drone API Generator

Richard Doell wrote to us requesting a HackRF One for a project idea he is working on. We were intrigued by the project, and very excited to hear that it is going to be open source. Richard has a background in robotics and computer vision, and he wants to create a universal automatic drone API generator for hobbyists and robotics junkies that will allow remote control vehicles to be controlled from a computer using GNU Radio. His HackRF One will enable him to collect data from the RC vehicles' transmitters. Keep us updated about the progress of your project, Richard!

Information Security Workshops

Stefan Hessel (of the blog Causa Finita) is a security expert who works at the Department of Law and Informatics at Saarland University in Germany. After work, he gets involved in his community through an IT working group, offering free classes at a local clubhouse that help beginners develop skills and knowledge in the areas of Internet safety and security. Stefan asked us to donate a HackRF One to help him teach the basics of SDR to the people who attend his classes and to demonstrate ways that attackers could gain access to private data through hardware hacking. Thanks Stefan, for sharing your expertise and using your workshops to bring awareness to these issues.

Liquid Fueled Rocket Building

Let's Build Rockets is a talented group of young amateur engineers who are designing and building a flyable, liquid-fueled rocket. This has proved challenging because currently most of the commercially available model rocket engine systems and electronics components are designed for solid-fueled rockets. Therefore they have had to design, manufacture, and test all of the system's components themselves. They are planning to use their free HackRF One as a receiver in the downlink portion of the rocket's control system, the design of which is based on the Copenhagen Suborbitals Sapphire Telemetry System. The downlink transfers mission data from the accelerometer, gyroscope, altimeter, compass, GPS, pressure and temperature sensors of the engine and fuel tanks, and atmospheric temperature sensors to a ground control station. Eric Simms wrote to us on behalf of Let's Build Rockets, saying:

“The communication that the HackRF enables will help us recover the rocket after the launch and analyze potential failure points. After doing lots of research, the HackRF is the most accessible receiver we've found, requiring the least amount of additional hardware and providing opportunities for future expansion.”

Let's Build Rockets is publishing all of their design files, code, and test data on github so that others can benefit from their learning and experience. We're excited to support this awesome, educational, open source project. Rocket on!

Emergency Communications

The Wantagh-Levittown Volunteer Ambulance Corps is a dedicated group of paramedics and dispatchers who provide emergency services to their community by answering 911 calls. While each ambulance in their facility has its own radio, this small nonprofit organization has had a difficult time finding the funds to invest in a radio for communications training. Their free HackRF One will enable them to receive and decode multiple simultaneous transmissions on their county's radio system. Mark Tomlin, Chief of Operations, wrote to us saying,

“Communications are vital in EMS, just as important as the vital signs of the patient themselves. Missing information from an incomplete report can be devastating to a patients outcome. Presenting ones self to the doctor correctly on the other end of the radio can be the difference in getting the order for the medication or not. These are things that can only come with experience. We now have the opportunity to present our experience to those who were not physically present at the time of notification. This should greatly improve the time it takes a new provider to get up to speed on medical control notifications.”

We are happy to put a free HackRF into the hands of someone who can use it to make the world a better place. It's very satisfying knowing that somewhere in New York, a HackRF One is enabling communication that could save lives.

MIT Splash Program

Every November, high school students from around the country and even around the world come to MIT for a program called Splash. It is a weekend where they can engage in unique and valuable learning experiences that are unavailable in a normal classroom setting. Riley Drake wrote to us asking for a HackRF One for a Software Defined Radio course he is planning to teach at Splash 2016, which will cover topics such as Digital Signal Processing, Decibels, Data Types, Sample Rates, Negative Frequencies, Quantization Error and Complex Numbers in Digital Signal Processing (course structure mirrors Michael Ossmann's online lessons). Having a HackRF One available for the class will allow students to run their code on a real radio and promote a discussion of the legal and regulatory issues of SDR. Good luck with your class Riley, and please send us pictures! We'd love to know how it goes.

Soldering Workshops

Hacklab Almeria is a growing group of developers and enthusiasts in Spain that are learning and collaborating together. When they first wrote to us in October of 2015, they had 30 members, but when we contacted them last month that number had increased to 50. Jesus Marin Garcia asked for several Throwing Star LAN Tap Kits for a workshop the group are offering to their newer members on electronics fundamentals and soldering. Spread the word, and good luck with your workshop!

OpenWebRX Support

András Retzler is the developer of a remote spectrum monitoring solution called OpenWebRX that gives users access to multiple SDR receivers worldwide. We gave András a free HackRF One, which he is using to improve support for that project. If you haven't already seen OpenWebRX, you should certainly check it out—it's really cool. He also plans to use his HackRF One to serve as a test station for another of his open source projects, qtcsdr, an open source amateur radio transceiver design using a Raspberry Pi 2 as a transmitter and an RTL-SDR as a receiver. As a company that is built on open source principles, we are very enthusiastic about supporting open source projects, and we are especially happy to help András with OpenWebRX.

Thanks again to everyone who has sent us a free stuff request. We are almost all caught up now, and we will announce winners for the first few months of 2016 soon. If you have an idea for a project using Great Scott Gadgets hardware and could benefit from free stuff, don't hesitate to tell us about it. If you don't ask, we can't say yes!

My, how time flies! The Great Scott Gadgets team has been busy, but we haven't forgotten all of your requests for FREE STUFF! We are working towards getting caught up, so please bear with us as we sort it all out. April had a lot of good submissions, and we are excited to reward several of you with free open source hardware. And to make up for being so behind, we even awarded a YARD Stick One this time, and we shipped it when it was brand new! Read on to learn about April's winning Free Stuff submissions.

Damon Wascom wrote to us requesting a HackRF One to assist AMSAT in testing transmission lines and filters for the next FOX-1C and Fox-1D CubeSats. Damon gave many convincing reasons and compelling arguments as to why we should award him a HackRF One for his project, but perhaps most compellingly Damon wrote:

"It would be awesome to apply this legendary and revolutionary RF hacking tool of the decade into the hacking together of the next amateur built, amateur radio spacecraft!"

Yup! Damon, make it so.

Jesus Sanchez wrote to us on behalf of the Advanced Communications Research Laboratory he founded at his university last February. The Advanced Communications Research Laboratory encourages its members to conduct research in the wide field of SDR and to promote open source software and hardware. We are happy to support these goals by awarding the Advanced Communications Research Laboratory a free HackRF One!

He also plans to use it for his own research on SDR and electronic motor control. Congratulations José, and let us know how your research goes!

Sean Semple wrote to us as president of the Association of Cyber Engineers (ACE) at Louisiana Tech University. ACE is an organization that was established a couple of years ago to promote the new Cyber Engineering degree program at Louisiana Tech, but also to help students learn about the cyber landscape as early in their career as possible. Great Scott Gadgets is happy to provide ACE with their very own YARD Stick One!

Once again, thanks to everyone that sent us a request. If you didn't send us a request, why not? It never hurts to ask. We look forward to seeing what you come up with next!

We've fallen behind on shipping Free Stuff and even further behind on announcements, but we're catching up!

Tariq Ahmad wrote to us representing the M5 hackerspace at UMASS Amherst. M5 has several ongoing projects including their Experimental College where students can take as well as teach classes just for the sake of learning. Tariq, we hope you and everyone at M5 can learn some new skills with your new HackRF One!

We have two tickets to give away, and we would like to give them to students who share our interests. You must meet Black Hat's criteria, and you will be responsible for your own travel and lodging.

We'll be busy at Black Hat USA this year. I'm teaching two sessions of my Software Defined Radio class, and I will be giving a talk at the Briefings about the NSA Playset. Additionally, Taylor and I will show off a new project called YARD Stick One at the Black Hat Arsenal.

Great Scott Gadgets is pleased to announce the recipients of our inaugural Free Stuff give-away. This being our first give-away, we got a little overexcited and ended up giving away 5 HackRF One units to people who made requests in February! We were excited to see so much interest in our Free Stuff program, and after much deliberation we were able to narrow the field down to these 5 entrants. Congratulations, and we can't wait to see what you do with your HackRF Ones!

Alex Page wrote to us representing the Interlock hackerspace in Rochester, New York, which has recently begun hosting SDR meetups. They have been encouraging those new to SDR as well as seasoned veterans, and they have made a space where they can all interact. We are awarding Interlock a HackRF One unit to encourage this sharing of knowledge. Thanks Alex, and keep up the good work.

JinGen Lim is a promising student and developer from Singapore. When HackRF One was released he used it as an inspiration to build his own open source device called CCManager. We awarded JinGen a HackRF One unit to see what he can come up with next. Thanks for making your ideas open source JinGen!

Rajesh Kannan is a licensed amateur radio operator and enthusiast as well as a rather successful amateur meteorologist. Rajesh has plans to use his HackRF One to help develop an HRPT satellite receiver with a group of students in India. Thanks Rajesh for igniting the RF spark in the next generation!
