A New Digital Mode For Radio Amateurs

There used to be a time when amateur radio was a fairly static pursuit. There was a lot of fascination to be had with building radios, but what you did with them remained constant year on year. Morse code was sent by hand with a key, voice was on FM or SSB with a few old-timers using AM, and you’d hear the warbling tones of RTTY traffic generated by mechanical teletypes.

By contrast the radio amateur of today lives in a fast-paced world of ever-evolving digital modes, in which much of the excitement comes in pushing the boundaries of what is possible when a radio is connected to a computer. A new contender in one part of the hobby has come our way from [Guillaume, F4HDK], in the form of his NPR, or New Packet Radio mode.

NPR is intended to bring high bandwidth IP networking to radio amateurs in the 70 cm band, and it does this rather cleverly with a modem that contains a single-chip FSK transceiver intended for use in licence-free ISM band applications. There is an Ethernet module and an Mbed microcontroller board on a custom PCB, which when assembled produces a few hundred milliwatts of RF that can be fed to an off-the-shelf DMR power amplifier.

Each network is configured around a master node intended to use an omnidirectional antenna, to which individual nodes connect. Time-division multiplexing is enforced by the master so there should be no collisions, and this coupled with the relatively wide radio bandwidth of the ISM transceiver gives the system a high usable data bandwidth.

Whether or not the mode is taken up and becomes a success depends upon the will of individual radio amateurs. But it does hold the interesting feature of relying upon relatively inexpensive parts, so the barrier to entry is lower than it might be otherwise. If you are wondering where you might have seen [F4HDK] before, we’ve previously brought you his FPGA computer.

You can now make flexible circuit boards of unlimited length. Trackwise was contracted out for making a wiring harness for the wing of a UAV and managed to ship a 26 meter long flexible printed circuit board. This is an interesting application of the technology — UAVs are very weight sensitive and wiring harnesses are heavy. Wings are straight, but they flex, and you need wires going from tip to tip. Flex circuits do all of this well, but first you need a technology that allows you to manufacture circuits that are as long as a wing. This is apparently something called ‘reel-to-reel’ technology, or some variant of continuous production. Either way, it’s cool, and we’re wondering what else this kind of circuit enables.

You may have noticed a few odd-shaped buildings going up in the last few years. These are buildings designed for indoor skydiving. Two went up around DC in the last year or so. What if you didn’t need a building? What if you could make an outdoor, vertical wind tunnel? Here you go, it’s the Aerodium Peryton.

KiCon, the first and largest gathering of hardware developers using KiCad, is happening April 26th in Chicago.

If KiCad isn’t your thing, PyCon is in Cleveland May 1-9. It couldn’t come at a better time: after losing LeBron, the Cleveland economy has plummeted 90%. Cleveland needs an industry now, and tech conferences are where it’s at. Go Browns.

For one reason or another, a few tech blogs wrote about a product on Tindie last week. It’s the SnapOnAir Raspberry Pi Zero PCB. This turns a Raspberry Pi Zero into a tiny, battery-powered handheld computer with a keyboard and display. This is just a PCB, and you’ll need to bring your own switches, display, and other various modules, but it is a compact device and if you need a small, handheld Linux thing, this is a pretty good solution.

Oh noes April Fools is tomorrow, which means the Internet will be terrible. Tip ‘o the hat to Redbox, though: they were the only one that sent out a press release to their waste of electrons by last Friday.

Build Your Own Metal Roller

Metal fabrication is a useful skill to have. There’s plenty you can achieve in your workshop at home, given the right tools. There’s lathes for turning, mills for milling, and bandsaws and dropsaws for chopping it all to pieces. But what do you do if you need to make hoops and bends and round sections? You build a metal roller, of course – and that’s precisely what [James Bruton] did.

The main body of the tool is built out of box section, chosen largely as it’s what [James] had lying around. Bearings are of the familiar pillow block variety, with 20 mm bright steel serving as the rollers due to its better tolerance than mild steel stock. Set screws hold the shafts in place to avoid everything sliding around the place. A 10-ton bottle jack then provides the force to gently bend the workpiece as it passes through the rollers.

Initial tests were positive, with the roller producing smooth curves in 4 mm thick steel bar. There were some issues with runout, which were easily fixed with some attention to the parallelism of the shafts. It’s a tidy build, and can serve as a basis for further upgrades in future if necessary.

We’ve seen DIY roll benders before, too. Video after the break.
