Becoming Your Own ISP, Just for Fun

When moving into a new house, it’s important to arrange for the connection of basic utilities. Electricity, water, and gas are simple enough, and then it’s generally fairly easy to set up a connection to an ISP for your internet connection. A router plugs into a phone line, or maybe a fiber connection and lovely packets start flowing out of the wall. But if you’re connected to the internet through an ISP, how is the ISP connected? [Kenneth] answers this in the form of an amusing tale.

It was during the purchase of data centre rack space that [Kenneth]’s challenge was laid down by a friend. Rather then simply rely on the connection provided by the data centre, they would instead rely on forging their own connection to the ‘net, essentially becoming their own Internet Service Provider.

This is known as creating an Autonomous System. To do this involves several challenges, the first of which is understanding just how things work at this level of networking. [Kenneth] explains the vagaries of the Border Gateway Protocol, and why its neccessary to secure your own address space. There’s also an amusing discussion on the routing hardware required for such a feat and why [Kenneth]’s setup may fall over within the next two years or so.

It’s not for the faint hearted, and takes a fair bit of paperwork, but [Kenneth] has provided an excellent guide to the process if you really, really just need to own your own corner of the internet. That said, there are other networking tricks to cut your teeth on if you’d like a simpler challenge, like tunneling IP over ICMP.


Books You Should Read: The Cuckoo’s Egg

The mid-1980s were a time of drastic change. In the United States, the Reagan era was winding down, the Cold War was heating up, and the IBM PC was the newest of newnesses. The comparatively few wires stitching together the larger university research centers around the world pulsed with a new heartbeat — the Internet Protocol (IP) — and while the World Wide Web was still a decade or so away, The Internet was a real place for a growing number of computer-savvy explorers and adventurers, ready to set sail on the virtual sea to explore and exploit this new frontier.

In 1986, having recently lost his research grant, astronomer Clifford Stoll was made a computer system admin with the wave of a hand by the management of Lawrence Berkeley Laboratory’s physics department. Commanded to go forth and administer, Stoll dove into what appeared to be a simple task for his first day on the job: investigating a 75-cent error in the computer account time charges. Little did he know that this six-bit overcharge would take over his life for the next six months and have this self-proclaimed Berkeley hippie rubbing shoulders with the FBI, the CIA, the NSA, and the German Bundeskriminalamt, all in pursuit of the source: a nest of black-hat hackers and a tangled web of international espionage.

Ask Hackaday: Selling Yourself as a Hacker

While there are plenty of hackers that hack just for the love of it, it’s no secret that many of us are looking to hit it big someday. Tales of the businesses like HP and Apple that started in someone’s garage inevitably lead to musings like, “Hey, I’ve got a garage!” and grand plans to turn that special idea into the Next Big Thing™. Many will try, most will fail for one reason or another, but hope springs eternal, and each new widget seems to start the entrepreneurial cycle again.

But for as much pressure as we may feel to be the next Packard, Wozniak, or Musk, not everyone is cut out to be the boss. Some of us have no interest in or aptitude for business — we don’t want to hire or fire people, we don’t want to wheel and deal, and we certainly don’t want to worry about salesmanship. Some of us just want to abstract all that complexity away and just find a job, preferably one that leverages the things we love to do.

Script Your Way Out Of Video Editing Drudgery

[Victor Frost] has a deep voice and a fancy top of the line camera. While one would assume this to be a more than generous situation for life to put a person in; it’s got its own set of problems. Mainly that his fantastic fancy camera uses the most modern version of the popular h.264 encoding scheme, h.265. Gasp!

While that too seems like a pro, unfortunately h.265 doesn’t play as nice with his editing software. The solution seems easy, just transcode it and get on your way. However, when you start talking about transcoding 4K video from a top-of-the line source and retaining the quality. Well… It can bring a processor to its knees. Since he’d rather be playing overwatch than transcoding video on his main computer, he decided to offload and automate the drudgery to his spare.

That’s how the Ingest-a-Tron 9000 came into play. It uses a lot of open source software and, yes, windows batch files to take the files off his camera, process it on one computer, and dump it to another. Now he can game (or edit) while he waits. For those of us who are estranged from Linux thanks to our favorite software, it’s good to know that there are still ways to automate away the pain. Video after the break.

Raspberry Pi Zero as a USB Stick

The Raspberry Pi Zero is small enough that it could almost be mistaken for a USB gadget, rather than a standalone computer. Maybe that was the inspiration that drove [Novaspirit] to completely “donglify” his Zero.

This is a great convenience hack if you’ve got a Zero just kicking around. With minimal soldering, he converted the Zero’s onboard female USB jacks into a male USB plug. From there on out, it’s all software, and the video (embedded below) takes you through all the steps on Windows.

Reverse Engineering and Networking The A/C Remote Control

IoT has become such an polarizing, overused term. But here it is in its essence: [zeroflow] had a thing (his airconditioner) and he needed to put it on the Internet.

For his contribution to this modern vernacular atrocity, he first had to build an IR debugging tool and reverse engineer the signals coming from the air conditioner’s remote. He wrote up a really good summary of the process, and worth reading. He loads up an IR library onto an Arduino and dumps the resulting 32 bits of information to his computer. In a process much like filling in the blanks on a word puzzle, he eventually determines which blocks of the data correspond to the remote’s different buttons.

Next he throws an array of IR LEDS and an ESP8266 onto a bit of protoboard. After writing some code, available on GitHub, he could set the temperature of his room from anywhere on the planet. We take it on faith that [zeroflow] has a compelling reason for doing so.

Bolstered by this success, he didn’t stop there. [Zeroflow] admits to having more than one thing on the Internet. Boom! Internet of things.

Hackaday Prize Entry: Cheap Visible Light Communication

[Jovan] is very excited about the possibilities presented by Visible Light Communication, or VLC. It’s exciting and new. His opening paragraphs is filled with so many networking acronyms that VLC could be used for, our browser search history now looks like we’re trying to learn english without any vowels.

In lots of ways he has good reason to be excited. We all know that IR can communicate quite a bit, but when you’re clever about frequency and color and throw in some polarizers with a mix of clever algorithms for good measure you can get some very high bandwidth communication with anything in line of site. You can do it for low power, and best of all, there are no pesky regulations to stand in your way.

He wants to build a system that could be used for a PAN (Personal Area Network). To do this he’ll have to figure out a way to build the system inexpensively and using less than a watt of power. The project page is full of interesting experiments and quite a few thesis on the subject of LEDs.

For example, he’s done work on how LEDs respond to polarization. He’s tested how fast an LED can actually turn on and off while still being able to detect the change. He’s also done a lot of work characterizing the kind of light that an LED emits. We don’t know if he’ll succeed yet, but we like the interesting work he’s doing to get there.
