I met up with [Kenji Larsen] at HOPE X last weekend, and I’m fairly certain he was the coolest person at a conference full of really cool people. Talking to him for a little bit, you get a sense of what it would be like to speak with [Buckmister Fuller], [Tesla], or any of the other ‘underappreciated, but not by people in the know’ minds scattered about history. I’ll just let his answers to our hacker bio questions demonstrate that.
[Kenji]’s project for The Hackaday Prize is the Reactron Overdrive. It’s not just one board he’s building here, but an entire suite of sensors, interfaces, and nodes that form a complete human to machines – note the plural ‘machines’ – interface. When you consider that no one knows what the Internet of Things actually is, and that [Kenji] is working on IoT 3.0, you get a sense that there’s really something here. Also, his project log has a Tron Recognizer in it. That has to count for something, right?
About a month ago, the FAA – the governing body for nearly everything that flies in US airspace – proposed an interpretation of their rules governing model aircraft. The world hasn’t ended quite yet, but if the proposed rules go into effect, an entire hobby will be destroyed in the United States. While congress has given the FAA authority over nearly everything that flies, there are specific laws saying what the FAA has no jurisdiction over – model aircraft being one of the major exceptions.
Congress, however, is working on a definition of model aircraft that is at least 10 years out of date and doesn’t have any leeway for the huge advances in technology that have happened since then. Specifically, all FPV flight with video goggles would be banned under the proposed FAA rules. Also, because model aircraft are defined as being for, ‘hobby or recreational purposes,’ anyone who flies a model aircraft for money – a manufacturer conducting flight tests on a new piece of equipment, or even anyone who records a video of their flight, uploads it to YouTube, and hits the ‘monetize’ button – would be breaking the law.
The proposed FAA rules for model aircraft are not in effect yet, and you can still make a public comment on the proposal until 11:59 PM EDT Friday. If you leave a comment, please make a well-reasoned statement on why the FAA’s interpretation of the rules governing model aircraft are overly broad, do not take into account technological advances made since the drafting of Congress’ working definition of ‘model aircraft,’ and the effects of a complete ban flying model aircraft for any type of compensation.
This is not a good comment.
Of course, if the proposed rules for model aircraft go through, the only option will be to turn to the courts. Historically, the FAA simply does not lose court cases. Recently, cases involving drones have come up with successful defenses and judges deciding in favor of drone operators. The legal services for the eventual court case challenging the proposed FAA rules will most likely be funded by the Academy of Model Aeronautics, who just so happen to be offering membership at 50% off.
Below is a video of some RC people we really respect – [Josh] from Flite Test and [Trappy] of Team BlackSheep – talking about what the proposed rule change would do to the hobby. There’s also a great podcast featuring the first lawyer to successfully defend drone use in federal court that’s worth a listen.
[Jose]’s OnionPi setup is based on the Adafruit version, but adds a few interesting features that make it even more useful. It’s battery-powered with about a day of charge time, has a built-in battery charger, Ethernet pass through, external 4G and WiFi antennas, all in a sealed case that makes the entire build impervious to the elements.
While this isn’t much of a hack per se, the amount of integration is impressive. There are switches to turn off each individual networking port, and all the relevant plugs are broken out to the front panel, with the AC input and USB serial connection using screw connectors that are supposedly very popular in Brazil.
[Jose] also brought along a new device that isn’t documented anywhere else on the web. It’s called NNCFA, or Nothing New Crypto For All. Using a Cubieboard, an interesting ARM single board computer with a SATA connector, [Jose] created a device that will mount TrueCrypt volumes on a hard drive and share them via Samba.
When we hear about the Internet of Things, we’re thinking it’s a portable device with a sensor of some kind, a radio module, and the ability to push data up to the Internet. There’s nothing that says a device that puts data on the Internet has to be portable, though, as [Jeff] from ReelyActive showed us at HOPE X last weekend.
[Jeff]’s startup is working on a device that turns every space into a smart space. It does this with radio modules connected to a computer that listen to Bluetooth and the 868, 915 and 2400MHz bands. These modules turn every place into a smart space, identifying who just walked into a room, and who is at a specific location. Think of it as the invisible foundation for any truly smart house.
The radio modules themselves are daisychained with Cat5 cable, able to be plugged into a hub or existing Ethernet drops. The software that makes the whole thing work can run on just about anything; if you want a Raspi to turn on the lights when you enter a room, or turn off a thermostat when you leave a building, that’s just a few lines of code and a relay.
The software is open source, and [Jeff] and his team are looking at making the hardware open. It’s a great idea, and something that would be a good entry for The Hackaday Prize, but ReelyActive is located in Montréal, and like Syria and North Korea, we’re not allowed to run a contest in Quebec.
The bulk of HOPE X was the talks, but arguably the far more interesting aspect of thousands of hackers and tinkerers under one roof is talking to everyone about what they’re doing. One guy hanging out at HOPE gave a quick lightning talk to a few people about something very interesting: something the FCC is pushing through that’s open to just about everything: it’s the FCC’s new CB radio service (you’ll want to click the presentation link at the very top of the page), giving anyone, not just people with a radio license, access to a huge swath of microwave spectrum.
The short version of the talk was the fact the FCC is extremely interested in opening up 100 to 200 MHz of spectrum at 3.5 GHz. The idea is to create something like cellular service that can either be implemented by companies, or normal, everyday people. The initial goal of this is to provide -possibly- free Internet to anyone with the right USB dongle. Since it’s just radio, and open to everyone, just about anything can be implemented.
This is something the FCC, Google, Microsoft, and a whole bunch of startups are extremely interested in, and the fact that about half of the spectrum will be open to anyone creates some interesting opportunities. A community-based freenet of wireless Internet links becomes an easy solution, and since the hardware to access 3.5 GHz is similar to other hardware that’s already available means building your own wireless ISP could be relatively easy in 12 to 18 months.
A transcript of the lightning talk is available below.
If you listen to [Bil Herd] and the rest of the Commodore crew, you’ll quickly realize the folks behind Commodore were about 20 years ahead of their time, with their own chip foundries and vertical integration that would make the modern-day Apple jealous. One of the cool chips that came out of the MOS foundry was the 6500/1 – used in the keyboard controller of the Amiga and the 1520 printer/plotter. Basically a microcontroller with a 6502 core, the 6500/1 has seen a lot of talk when it comes to dumping the contents of the ROM, and thus all the code on the Amiga’s keyboard controller and the font for the 1520 plotter – there were ideas on how to get the contents of the ROM, but no one tried building a circuit.
[Jim Brain] looked over the discussions and recently gave it a try. He was completely successful, dumping the ROM of a 6500/1, and allowing for the preservation and analysis of the 1520 plotter, analysis of other devices controlled by a 6500/1, and the possibility of the creation of a drop-in replacement for the unobtanium 6500/1.
The datasheet for the 6500/1 has a few lines describing the test mode, where applying +10 VDC to the /RES line forces the machine to make memory fetches from the external pins. The only problem was, no body knew how to make this work. Ideas were thrown around, but it wasn’t until [Jim Brain] pulled an ATMega32 off the top of his parts bin did anyone create a working circuit.
The code for the AVR puts the 6500/1 into it’s test mode, loads a single memory location from ROM, stores the data in PORTA, where the AVR reads it and prints it out over a serial connection to a computer. Repeat for every location in the 6500/1 ROM, and you have a firmware dump. This is probably the first time this code has been seen in 20 years.
Now the race is on to create a drop-in replacement of what is basically a 6502-based microcontroller. That probably won’t be used for much outside of the classic and retro scene, but at least it would be a fun device to play around with.
[Josh Datko] was wandering around HOPE X showing off some of his wares and was kind enough to show off his CryptoCape to us. It’s an add on board for the BeagleBone that breaks out some common crypto hardware to an easily interfaced package.
On board the CryptoCape is an Atmel Trusted Platform Module, an elliptic curve chip, a SHA-256 authenticator, an encrypted EEPROM, a real time clock, and an ATMega328p for interfacing to other components and modules on the huge prototyping area on the cape.
[Josh] built the CryptoCape in cooperation with Sparkfun, so if you’re not encumbered with a bunch of export restrictions, you can pick one up there. Pic of the board below.
[Kenji]’s project for The Hackaday Prize is the Reactron Overdrive. It’s not just one board he’s building here, but an entire suite of sensors, interfaces, and nodes that form a complete human to machines – note the plural ‘machines’ – interface. When you consider that no one knows what the Internet of Things actually is, and that [Kenji] is working on IoT 3.0, you get a sense that there’s really something here. Also, his project log has a Tron Recognizer in it. That has to count for something, right?
