What Would It Take To Recreate Bell Labs?

It’s been said that the best way to stifle creativity by researchers is to demand that they produce immediately marketable technologies and products. This is also effectively the story of Bell Labs, originally founded as Bell Telephone Laboratories, Inc. in January 1925. As an integral part of AT&T and Western Electric, it enjoyed immense funding and owing to the stable financial situation of AT&T very little pressure to produce results. This led to the development of a wide range of technologies like the transistor, laser, photovoltaic cell, charge-coupled cell (CCD), Unix operating system and so on. After the break-up of AT&T, however, funding dried up and with it the discoveries that had once made Bell Labs such a famous entity. Which raises the question of what it would take to create a new Bell Labs?

As described in the article by [Brian Potter], one aspect of Bell Labs that made it so successful was that the researchers employed there could easily spend a few years tinkering on something that tickled their fancy, whether in the field of semiconductors, optics, metallurgy or something else entirely. There was some pressure to keep research focused on topics that might benefit the larger company, but that was about it, as the leadership knew that sometimes new technologies can take a few years or decades to come to fruition.

Read All About It: The 2024 Supercon Site Is Live

With the 2024 Hackaday Supercon just a couple weeks away, we’re pleased to announce that the official site for the three-day event is now live!

On the brand-new Supercon page, you can find a listing of all of our fantastic speakers, the hands-on workshops, and perhaps most importantly, the schedule of when everything is happening. As always, Supercon is jam-packed with incredible content, so you’ll want to consult with the schedule to navigate your way through it. Don’t worry if it ends up that two talks you want to see are scheduled for the same time — we’ll be recording all of the talks and releasing them on the Hackaday YouTube channel, so you won’t miss out.

If you’re still on the fence, we do have a few tickets left at the time of this writing. All of the workshops are full at this point, but you can still get on the waiting list for a few of them just in case a spot opens up.

DIY Core Rope Memory Z80 Demonstrator Generating A Fibonacci Sequence

We’ve seen a few retro products using core rope memory, such as telephone autodiallers. Obviously, we’ve covered the Apollo program computers, but we don’t think we’ve seen a complete and functional DIY computer using core rope memory for program storage until now. [P-lab] presents their take on the technology using it to store the program for a Z80-based microprocessor demoboard, built entirely through-hole on a large chunk of veroboard.

For the uninitiated, core rope memory is a simple form of ROM where each core represents a bit in the data word. Each wire represents a single program location. Passing a wire through the core sets the corresponding bit to a logic 1, else 0. These wires are excited with an AC waveform, which is coupled to the cores that host a wire, passing along the signal to a pickup coil. This forms an array of rudimentary transformers. All that is needed is a rectifier/detector to create a stable logic signal to feed onto the data bus.

Winamp Taken Down: Too Good For This Open Source World

If you picked today in your hackerspace’s sweepstake on when Winamp would pull their code repository, congratulations! You’re a winner! The source for the Windows version of the venerable music player was released on GitHub three weeks ago, and after some derision over its licence terms, a bunch of possible open source violations, and the inadvertent release of some proprietary third-party code, it’s been taken down. We’re sure that if you still have a burning desire to look at it then it won’t be too difficult to find a copy through your favorite search engine, leaving the question of what really just happened.

It’s fairly obvious that the owners of the code lacked some level of understanding of just what open source really is, based on their not-really-open licence and all those code leaks. They did back down on not allowing people to create forks, but it’s evident that they didn’t anticipate the reaction they got. So were they merely a bit clueless, or was it all just a publicity stunt involving a piece of software that’s now of more historical than practical interest? It’s possible we’ll never know, but the story has provided those of us sitting on the fence eating popcorn with some entertainment.

Module Makes Noisy Projects Easy

You want to add voice, music, or sound effects to your project. What do you do? Sure, it is easy enough to plug a Raspberry Pi or some other tiny computer, but that’s not always desirable from a power, space, or cost point of view. [Mellow_Labs] shows a module that makes it simple to add sound to any project. The little board is just big enough to house a speaker and doesn’t cost much. Check it out in the video below.

The device allows you to preload tracks as MP3 files. There are two ways to control it: via a serial port, or using a single pin that can accept commands like you might expect from a MP3 player, like play and next track.

Clockwork Derby gameboard

Clockwork Derby: Digital Robo Rally, Steampunk Style

Inspired by the classic game Robo Rally, [Ytec3D]’s Clockwork Derby takes tabletop gaming to the next level by combining steampunk aesthetics with automation. We recently had the chance to see it live at Hackfest, together with [Ytec3D]’s animatronic tentacle, and we can say that his new take on playful robotics offers a unique experience for game enthusiasts. The 300×420 mm board uses magnets, motors, and card readers to handle up to eight players, creating a smooth, automated version of Robo Rally where players can focus on strategy while the board handles movement.

In Clockwork Derby, game pieces are moved by a magnetic system controlled by the board, which rotates and shifts pieces in real-time. Each player uses a card reader to program moves, with up to five cards per round. The board scans these cards via barcode scanners, so you don’t have to worry about tracking your moves or adjusting game pieces manually. [Ytec3D]’s game rules have been optimized for the automated setup, allowing for smoother gameplay and an emphasis on strategic choices.

The project is a standout for hackers and tinkerers who appreciate blending physical mechanics with digital precision. It’s a great example of how classic games can be modernized with a bit of ingenuity and tech. For those interested in DIY gaming projects or automation, Clockwork Derby is definitely worth exploring. To dive deeper into the build details and see more of the project, visit [Ytec3D]’s project page for an in-person look at this inventive tabletop game!
