Build Your Own Dial-Up ISP – Now With Modem Pool!

May 30, 2020 by Lewin Day 54 Comments

When it was the only viable option, the screech and squeal of dial-up internet was an unwelcome headache to many. But now that its time has passed, it’s gained a certain nostalgia that endears it to the technophiles of today. [Doge Microsystems] is just one such person, who has gone all out to develop their very own dial-up ISP for multiple clients.

The retro network is based on an earlier single-device experiment, with a Raspberry Pi 3B acting as the dial-up server. It’s hooked up to four modems, three of which are connected over USB-serial adapters implementing hardware flow control.

Obviously, four analog phone lines are hard to come by in this day and age, so [Doge] uses Asterisk along with a series of Linksys SIP devices to create their own PBX network. Each modem gets a phone line, with four left over for clients to dial in.

To connect, users can either call a certain modem directly, or dial a special number which rings the whole pool. Thanks to mgetty, each modem is set up to answer on a different number of rings to allow the load to be shared. Once connected, a PPP daemon handles connecting the user to the Internet at large.

While it’s unlikely we’ll all be ringing [Doge]’s house to get our next YouTube fix, owning your own dial-up ISP is certainly an admirable feat. We’d love to see it deployed in the field sometime, perhaps at a hacker conference or Burning Man-type event. Of course, if you’ve got your own old-school network pumping data, be sure to let us know! Video after the break.

Help Us Throw More Cycles At The Coronavirus Problem

May 10, 2020 by Mike Szczys 45 Comments

The Hackaday community has answered the call and put their computers put to work folding proteins found in the coronavirus. Team_Hack-a-Day ranks #44 in the world so far this month, and I’ve seen us rank as high as #19 on 24-hour leaderboards.

Want to join the fight? Donate some of those computing cycles you’re not using to battling SARS‑CoV‑2. You’re probably not an epidemiologist or a vaccine researcher, but you can make their jobs easier by providing them with the data they need through the Folding@home Project.

As Dan Maloney explained in his excellent article on protein folding, understanding the incredibly complex folding behavior of the proteins in the virus will be key to finding treatments and possibly a vaccine. Folding@home connects countless computers via the internet and is now the largest supercomputer in the world, consisting of over 3.5 million CPUs and over half a million GPUs. The resulting data is freely available to researchers.

Let’s take a look at how easy it is to get up and running, how a GPU can supercharge a setup, and dip into the stats for Team_Hack-a-Day’s effort.

ICANN Board Withhold Consent For .ORG Deal

May 1, 2020 by Jenny List 10 Comments

Over the past few months there has been a battle waging in the world of domain names; the overseeing body ICANN had hatched a plan to transfer the entire .org registry to a private company, to significant opposition from .org domain holders, concerned citizens, and the Electronic Frontier Foundation. Part of the process before the deadline for handover on the 4th of May was a due dilligence process during which the ICANN board would review submissions related to the deal, and after completing that task the board have witheld their consent for it to go ahead. As you might expect the EFF are declaring a victory, but they also make the point that one of the reasons the ICANN board rejected the deal was a potential risk of a debt liability for the organisation.

It’s tempting to frame this as a rare victory for the Little Guy in the face of The Man, but the reality is probably more nuanced. When the deal was hatched the world had not yet come to terms with the COVID-19 pandemic, meaning that the thought of a post-virus economic slump would not yet have been on their minds. It’s thus not unexpected that the ICANN board would think about the financial aspects of it as well as the many objections, because in a time of economic pain the possibility of it going sour would be significantly increased. The future of the .org and other registries should remain a concern to internet users, because after all, this is not the first time such a thing has happened.

SOLID Promises A New Approach To How The Web Works

March 30, 2020 by Lewin Day 71 Comments

As it stands on the modern Internet, your data is no longer your own. Your emails, photos, and posts all live on servers owned by large corporations. Their policies give them access to your data, which is mined to generate advertising revenue. And if you want your data back, there are innumerable hoops to jump through. Want it deleted entirely? Good luck.

Tim Berners-Lee, original creator of the World Wide Web, is behind the project.

Sir Tim Berners-Lee, as the original creator of what became the Web, has drawn issue with the current state of play. To move the ball on the issue, he’s been working on a design for decentralized internet and the efforts have led to the establishment of the Solid project. The goal is to rectify online privacy and ownership issues and give users greater control over their personal data.

The big question is how do you do that? When SOLID was announced last year there were few if any details on the approach taken by the program. But since then, more details have surface and you can even take an early version of the program for a spin. Let’s take a look.

Custom Reddit Keyboard Only Needs One Hand

March 17, 2020 by Tom Nardi 12 Comments

Sometimes you might want to browse your favorite social media site while eating a sandwich, or throwing darts, or fending off an attacker with a sword. You know, normal things that might occupy only one of your hands. If you’ve ever found yourself in such a situation, then this custom Reddit keyboard could be for you.

Built by [jangxx], this little board is about as simple as it gets. Even if you aren’t looking for a way to browse /r/cooking while practicing your single-handed egg cracking technique, the same principles could be used to quickly throw together a macro keyboard for whatever your particular needs might be.

Inside the 3D printed enclosure is nothing more exotic than an Arduino Pro Micro and five Cherry MX Red switches. The switches have been wired directly to the GPIO pins on the Arduino, and a simple Sketch takes care of the rest. [jangxx] has written the code in such a way that you can easily define the mapping of USB HID keys to physical switches right at the top of the file, making it easy to reuse for your own purposes.

As simple as this project is, we really like the trouble that [jangxx] went through on the 3D printed key caps. The white up and down arrows allow you to navigate through the posts, and the center key selects the one you want to view. Since it’s for Reddit, naturally the red and blue buttons for rapid voting. When you want to go back to the list of posts, just hit the center button again.

Back in 2011 we saw a dedicated Reddit voting peripheral, but we think the addition of simple navigation keys makes this project a bit more compelling. Incidentally, if you can think of any other reason you might want a one-handed keyboard for browsing Reddit…we definitely don’t want to hear about it.

If Coffee == True {

March 7, 2020 by Bryan Cockfield 14 Comments

Having a shared coffee maker in the workplace is both a blessing and a curse. It’s nice to have constant access to coffee, but it can be frustrating to find the coffee pot emptied right as you walk in to the break room. To solve this problem in their office, [Vitort] and co. built an IOT solution that notifies everyone of the current coffee status on a Slack channel.

This project wasn’t built just as a convenience for the office, either. It makes extensive use of AWS SNS, the simple notification system from Amazon Web Services because they wanted to learn to use this technology specifically. Besides the notification system, the device itself is based on a NodeMCU/ESP8266, communicating over WiFi, and is a simple push-button design which coffee drinkers push when a fresh pot is made, and then push again when the coffee is empty.

While relatively straightforward, this project is a good one to look at if you’ve been interested in AWS at all, especially the simple notification system. It’s a pretty versatile tool, and all of the code used in the project is available on the project page for your reading pleasure. If you’re more interested in the coffee aspect of this project, we have a special coffee maker for you too.

Sky Is New Limit For Dot Com Domain Prices

February 13, 2020 by Kristina Panos 68 Comments

Earlier this week, domain name registrar Namecheap sent out an email to all customers advising them of a secret deal that went down between ICANN and Verisign sometime late last year. It has the potential to change the prices of domain names drastically over time, and thus change the makeup of the Internet as we know it.

Domain names aren’t really owned, they’re rented with an option to renew, and the annual rate that you pay depends both on your provider’s markup, but also on a wholesale rate that’s the same for all names in that particular domain. This base price is set by ICANN, a non-profit.

Officially, this deal is a proposed Amendment 3 to the contract in place between Verisign and ICANN that governs the “.com” domain. The proposed amendment would let Verisign increase the wholesale rental price of “.com” domain names by 7% per year for the next four years. Then there will be a two-year breather, followed by another four years of 7% annual hikes. And there is no foreseeable end to this cycle. We think it seems reasonable to assume that the domain name registrars might pass the price gouging on to the consumer, but that really remains to be seen.

The annual wholesale domain name price has been sitting at $7.85 since 2012, and as of this writing, Namecheap is charging $8.88 for a standard “.com” address. If our math is correct, ten years from now, a “.com” domain will cost around $13.50 wholesale and $17.50 retail. This almost-doubling in price will affect both small sites and companies that hold many domain names. And the increase will only get more dramatic with time.

So let’s take a quick look at the business of domain names.
