Your Undocumented Project May Also Baffle People Someday

November 26, 2024 by Donald Papp 49 Comments

What’s life without a little mystery? There’s one less rolling around after historians finally identified a donated mystery machine that had been in storage for years.

Feeding dough through this machine may have been faster, but probably not safer.

The main pieces of the machine are about a century old and any staff who may have known more about the undocumented device were no longer around to ask. The historical society finally posted pictures and asked for any insights, which eventually led to solving the mystery.

The machine is in all likelihood a beaten biscuit maker, which was a type of dense baked good popular in the American south. Making them called for a long and labor-intensive process of pounding and working the dough, and the society says this machine was likely created by a fellow trying to help his aunt streamline her business, offloading the labor of working the dough to a machine.

The machine had no branding of any sort and lacked any identifying marks. Its purpose was doubtlessly obvious at the time, but no records remained and quite possibly none existed in the first place. Sound familiar? Perhaps someday our own undocumented projects and prototypes will mystify people. It’s certainly happened in the case of mysterious Roman dodecahedrons, which remain a head-scratching mystery.

Commodore 64 Reports The News

March 22, 2023 by Bryan Cockfield 13 Comments

In the late 80s and into the 90s, [Cameron Kaiser] aka [ClassicHasClass] was an aspiring journalist, first becoming interested in the career in elementary school and then working on various publications into university. At some point, he started using a piece of software for laying out newspapers called The Newsroom which, he admits, was lacking a lot of tools that would have been modern even for the time, but had an otherwise agreeable price tag thanks to its focus more on home desktop publishing and newsletter production than on full-scale newspaper operations. It did have one interesting feature that he never could figure out, though, at least until he went back and pieced this mystery together.

The software itself ran on the Apple II and was eventually ported to other systems of the era, including the Commodore 64. The mystery feature was known as “Wire Service” and appeared to be a way that users of the software who had a modem could connect with one another and share news releases, layouts, graphics, and other content created in Newsroom, but in the days where it would have been modern never was able to connect to anything. In fact, it was eventually abandoned by the developers themselves in later releases of the software. But [ClassicHasClass] was determined to get it working.

Ask Hackaday: What’s Going On With Mazdas In Seattle?

February 10, 2022 by Al Williams 56 Comments

What hacker doesn’t love a puzzle? We have a doozy for you. According to KUOW — the NPR affiliate in Seattle — they have been getting an unusual complaint. Apparently, if you drive a Mazda made in 2016 and you tune to KUOW, your radio gets stuck on their frequency, 94.9 MHz, and you can’t change it.

According to a post from the radio station, it doesn’t just affect the FM radio. A listener named Smith reported:

“I tried rebooting it because I’ve done that in the past and nothing happened,” Smith said, “I realized I could hear NPR, but I can’t change the station, can’t use the navigation, can’t use the Bluetooth.”

Mystery WWII Navy Gear With Magic Eye

January 28, 2022 by Chris Lott 34 Comments

There’s an unknown piece of military electronic gear being investigated over on [Usagi Electric]’s YouTube channel (see video below the break). The few markings and labels on the box aren’t terribly helpful, but along with the construction and parts, seem to identify it as relating to the US Navy from the WWII era. Its central feature is a seeing-eye tube and an adjustment knob. [David] does a bit of reverse engineering on the circuit, and is able to fire it up and get it working, magic eye squinting and all.

But there’s still the unanswered question, what was this thing supposed to do? Besides power, it only has one input signal. There are no outputs, except the “data” presented visually by the magic eye tube. Commenters have suggested it was used with sonar equipment, calibration tool, RTTY tuning aid, light exposure meter, etc. But if you dust off your copy of Navships 900,017 “Radar Systems Fundamentals” from 1944 and turn to page 249, there’s a section entitled Tuning Indicator that describes this circuit, almost.

We’re Not Joking Around; Something BIG Is Coming

April 18, 2014 by Mike Szczys 95 Comments

Hackaday Something BIG Logo Countdown timer, a special presentation on the first of this month, and now there’s been some weekly mystery posts. What are we playing at? We’re not playing. This is real.

That timer is now below the 10-day mark and with every passing minute we become more giddy about the unrelenting awesome that is to come. Want to know what we’re talking about without waiting until the end? Are you a clever person? Then you might just be able to figure it all out. Try to unlock the clues from past weeks, and hit the Freenode ##hackaday channel on IRC if you need some hints (we’re certainly not going to post spoilers here).

We wouldn’t mind some help with a whisper campaign as well. Spout your conspiracy theories, and your delight at solving our puzzles to whoever will listen. Get it right and you can do the “I told you so” thing for the rest of the…. oops, that would be telling.

Help Identify This Vintage Electronics Component

[Windell] over at Evil Mad Scientist Laboratories has reached out in order to help them identify a mystery piece of electronics equipment they came across a few years ago. Discovered at an electronics surplus store, the mystery component looks like a cross between an over-sized chess board and a breadboard. Failing to identify it they eventually disposed of the board, snapping a couple of pictures for good measure before it was gone for good.

Recently while visiting a local electronics flea market, they came across what looked to be a similar, though much smaller board. This piqued their curiosity and compelled them to dig out the pictures of the mystery board in hopes of finally discovering what it was. Using markings on the new board they found, the team at EMSL located some images of a patchboard cartridge that looked quite similar to their mystery object. Upon closer inspection however, they think that the two pieces might be related, but are not quite the same item.

Swing by their site and chime in if you happen to have any good leads – we’re sure they will appreciate it.
