Hackaday Links: July 28, 2019

It looks like Apple is interested in buying Intel’s modem chip business. Seriously interested; a deal worth $1 billion could be announced as early as this week. That might look like a small potato purchase to the world’s biggest company – at least by market capitalization – but since the …read more

Teardown Of A 50 Year Old Modem

A few years ago, I was out at the W6TRW swap meet at the parking lot of Northrop Grumman in Redondo Beach, California. Tucked away between TVs shaped like polar bears and an infinite variety of cell phone chargers and wall warts was a small wooden box. There was a …read more

Old Modem, New Internet.

Do you remember the screeching of a dial-up modem as it connected to the internet? Do you miss it? Probably not, but [Erick Truter] — inspired by a forum post and a few suggestions later — turned a classic modem into a 3G Wi-Fi hotspot with the ubiquitous Raspberry Pi Zero.

Sourcing an old USRobotics USB modem — allegedly in ‘working’ condition — he proceeded to strip the modem board of many of its components to make room for the new electronic guts. [Truter] found that for him the Raspberry Pi Zero W struggled to maintain a reliable network, and …read more

Router Rebooter Eliminates Hassles

Some low-end or older routers might get you a decent WiFi network in your house or apartment, but often these cheaply made devices are plagued with subtle software problems that cause the router itself to become unresponsive after a few days of operating. One solution is to just power cycle the router by hand whenever the Internet disappears, but a better solution is to build something that does that for you.

[Charlie] had this problem as the de facto IT person in his family, and didn’t want to keep getting bothered for such a simple problem. His solution involves a …read more

TRS-80 Model 100 Goes Cellular

There are a few old products that have rabid fan bases, and the TRS-80 Model 100 is one of those. Depending on your point of view it’s either a small laptop or a large organizer, but in 1983 it was the ultimate computer on the go. The $1100 version had a whopping 8K of memory and the LCD screen showed 8 lines of 40 characters in glorious monochrome. One cool feature was the built-in 300 baud phone modem, which [Trammell Hudson] wanted to try, but he doesn’t have a landline. He tried a VOiP phone, but it wouldn’t wedge into …read more

A Web-Based Modem

If you are beyond a certain age, you will recall when getting on the Internet was preceded by strange buzzing and squawking noises. Modems used tones to transmit and receive data across ordinary telephone lines. There were lots of tricks used to keep edging the speed of modem up until — at the end — you could download (but not upload) at a blazing 56,000 bits per second. [Martin Kirkholt Melhus] decided to recreate a modem. In a Web browser. No kidding.

We started to say something about a modem in the cloud, but that wouldn’t really be accurate. The …read more

RetroModem for the Commodore 64

Retrocomputers are fun, but ultimately limited in capability compared to modern hardware. One popular pursuit to rectify this is the connection of early home computers to the Internet. To that end, [que] built the Retromodem for the Commodore 64.

The build starts with a case from an Intel 14.4 modem. A little fast for the Commodore 64 era, but anachronism is charming when done tastefully. Inside is an Arduino with an ethernet module to handle the heavy lifting of carrying packets to the outside world.  [que] took the time to wire up status LEDs for the proper vintage look, which …read more

Acoustic Coupler Pole-Vaults Over China’s Firewall

[agp.cooper]’s son recently went to China, and the biggest complaint was the Great Firewall of China. A VPN is a viable option to get around the Great Firewall of China, but [agp] had a better idea: an acoustic coupler for his son’s iPhone.

Hackaday readers of a recent vintage might remember an old US Robotics modem that plugged into your computer and phone line, allowing you to access MySpace or Geocities. Yes, if someone picked up the phone, your connection would drop. Those of us with just a little more experience under our belts will remember the acoustic coupler modem …read more

33C3: Dissecting 3G/4G Phone Modems

[LaForge] and [Holger] have been hacking around on cell phones for quite a while now, and this led to them working on the open cellphone at OpenMoko and developing the OsmocomBB GSM SDR software. Now, they are turning their sights on 3G and 4G modems, mostly because they would like to use them inside their own devices, but would also like to make them accessible to the broader hacker community. In this talk at the 33rd Chaos Communications Congress (33C3), they discuss their progress in making this darkest part of the modern smartphone useful for the rest of us.

This …read more
