We have just posted all of the design files and schematics of our smallest HamShield yet: The HamShield Mini. You can find design files and schematics here. We have also posted a pinout guide, which is available here.  Looking to buy HamShield Mini? You can find that here. HamShield Mini is based on the larger HamShield 1.0, but is designed for use in low power, small footprint applications, such as: CubeSats Drones and other UAS repeater platforms High altitude balloon projects Kites Miniaturized, handheld tracking and radio devices Integrated OEM designs 3.3V microcontroller systems and low power applications HamShield Mini...

You can find HamShield: Lora Edition here. There is a lot of hype over LoRa and its purported range. As an amateur radio operator and commercial radio professional, I cringe every time I hear the word range. I have seen "up to 20 miles" advertised for unlicensed 100mW variants in the 900MHz band. However, in my testing, this is absolutely absurd and impossible. Unless you have an antenna on the top of a tall tower or mountain, you will probably see about half a mile or less at ground level. Still pretty good, but not 20 miles. Now, instead of...

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...
