One of our staff has written a great guide on how to send and receive DTMF with HamShield. This will allow you to do all sorts of fun things: Control an RC car with your handheld radio Send data back and forth between two HamShields Build your own autopatch  Send weather telemetry  Command and control commands for your CubeSat The emerging field of long distance amateur radio robotics (More on this soon!)

Sometimes noise can be a good thing. Introducing the Infinite Noise TRNG, a true random number generator from 13-37.org electronics in Germany. You can use this hardware TRNG for a variety of security applications, as a truly random source for statistical applications, SSL servers, and is particularly useful in feeding truly random data into virtual hosting environments. It is also just fun! While operating systems try to generate random numbers, the results can be not so random. Some try to create pseudo random, but repeatable, data using algorithms. Some try to utilize an aspect of the hardware or user input...

HamShield Mini is a cost effective, power friendly amateur radio device, based on the original HamShield design. You can almost get two mini's for the price of one original HamShield! We have taken the Auctus AT1846S, made it 3.3V friendly, and lightened the current requirements of the amplifier. While the RF output is a little lower (about 200mW), you still get tri-band coverage in 144MHz, 220MHz and 440MHz amateur radio bands, and our RF filters exceed regulatory requirements. It also still has the same wideband transceiving capability, making it useful for non-amateur radio applications and prototyping. The other great thing...

We are excited to announce that our new 1 Watt 440MHz LoRa shield is finally here! Works with Arduino and Raspberry Pi. Now you can use a variety of digital modes, including one of the hottest new spread spectrum modes: LoRa. LoRa stands for Long Range and has some impressive weak signal performance. We have been able to successfully receive signals from -120 dBm to -130 dBm at an impressive 3000 bits per second over the 70cm band. This allows for some pretty ridiculous operating conditions, such as multi-mile non-line of sight paths with rubber duck antennas through forests. Of course, with...

As our company grows, we have been working hard to not only bring you great hardware, but also produce a series of guides to help you get started with each one of our products. Recently, we recruited a great technical writer to help with this. Our first posted guide is called: Building HandyTalkie: First Project with HamShield Hardware and Library   Guides can be found under our "Documentation" section, and will be posted under each product section going forward. For HamShield, we will help you get the libraries installed, write your first project, with future guides to help you get...
