It’s Not a Leica, It’s a Lumix

There’s an old adage in photography that the best camera in the world is the one in your hand when the shot presents itself, but there’s no doubt that a better camera makes a difference to the quality of the final image. Among decent quality cameras the Leica rangefinder models have near cult-like status, but the problem is for would-be Leica owners that they carry eye-watering prices. [Cristian Băluță] approached this problem in s special way, by crafting a Leica-style body for a Panasonic Lumix camera. Given the technology relationship between the Japanese and German companies, we can see the appeal.

While the aesthetics of a Leica are an important consideration, the ergonomics such as the position of the lens on the body dictated the design choices. He was fortunate that the internal design of the Lumix gave plenty of scope for re-arrangement of parts, given that cameras are often extremely packed internally. Some rather bold surgery to the Lumix mainboard and a set of redesigned flex PCBs result in all the parts fitting in the CNC machined case, and the resulting camera certainly looks the part.

The write-up is in part a journey through discovering the process of getting parts manufactured, but it contains a lot of impressive work. Does the performance of the final result match up to its looks? We’ll leave you to be the judge of that. Meanwhile, take a look at another Leica clone.

The Time Clock Has Stood the Test of Time

No matter the item on my list of childhood occupational dreams, one constant ran throughout: I saw myself using an old-fashioned punch clock with the longish time cards and everything. I now realize that I have some trouble with the daily transitions of life. In my childish wisdom, I somehow knew that doing this one thing would be enough to signify the beginning and end of work for the day, effectively putting me in the mood, and then pulling me back out of it.

But that day never came. Well, it sort of did this year. I realized a slightly newer dream of working at a thrift store, and they use something that I feel like I see everywhere now that I’ve left the place — a system called UKG that uses mag-stripe cards to handle punches. No it was not the same as a real punch clock, not that I have experience with a one. And now I just want to use one even more, to track my Hackaday work and other projects. At the moment, I’m torn between wanting to make one that uses mag-stripe cards or something, and just buying an old punch clock from eBay.

I keep calling it a ‘punch clock’, but it has a proper name, and that is the Bundy clock. I soon began to wonder how these things could both keep exact time mechanically, but also create a literal inked stamp of said time and date. I pictured a giant date stamper, not giant in all proportions, but generally larger than your average handheld one because of all the mechanisms that surely must be inside the Bundy clock. So, how do these things work? Let’s find out.

Bundy’s Wonder

Since the dawn of train transportation and the resulting surge of organized work during the industrial revolution, employers have had a need to track employees’ time. But it wasn’t until the late 1880s that timekeeping would become so automatic.

Willard Le Grand Bundy was a jeweler in Auburn, New York who invented a timekeeping clock in 1888. A few years later, Willard and his brother Harlow formed a company to mass-produce the clocks.

By the early 20th century, Bundy clocks were in use all over the world to monitor attendance. The Bundy Manufacturing Company grew and grew, and through a series of mergers, became part of what would become IBM. They sold the time-keeping business to Simplex in 1958.

Looking at Willard Le Grand Bundy’s original clock, which appears to be a few feet tall and demonstrates the inner workings quite beautifully through a series of glass panels, it’s no wonder that it is capable of time-stamping magic.

Part of that magic is evident in the video below. Workers file by the (more modern) time clock and operate as if on autopilot, grabbing their card from one set of pockets, inserting it willy-nilly into the machine, and then tucking it in safely on the other side until lunch. This is the part that fascinates me the most — the willy-nilly insertion part. How on Earth does the clock handle this? Let’s take a look.

Okay, first of all, you probably noticed that the video doesn’t mention Willard Le Grand Bundy at all, just some guy named Daniel M. Cooper. So what gives? Well, they both invented time-recording machines, and just a few years apart.

The main difference is that Bundy’s clock wasn’t designed around cards, but around keys. Employees carried around a metal key with a number stamped on it. When it was time clock in or out, they inserted the key, and the machine stamped the time and the key number on a paper roll. Cooper’s machine was designed around cards, which I’ll discuss next. Although the operation of Bundy’s machine fell out of fashion, the name had stuck, and Bundy clocks evolved slightly to use cards.

Plotting Time

You would maybe think of time cards as important to the scheme, but a bit of an afterthought compared with the clock itself. That’s not at all the case with Cooper’s “Bundy”. It was designed around the card, which is a fixed size and has rows and columns corresponding to days of the week, with room for four punches per day.

Essentially, the card is mechanically indexed inside the machine. When the card is inserted in the top slot, it gets pulled straight down by gravity, and goes until it hits a fixed metal stop that defines vertical zero. No matter how haphazardly you insert the card, the Bundy clock takes card of things. Inside the slot are narrow guides that align the card and eliminate drift. Now the card is essentially locked inside a coordinate system.

So, how does it find the correct row on the card? You might think that the card moves vertically, but it’s actually the punching mechanism itself that moves up and down on a rack-and-pinion system. This movement is driven by the timekeeping gears of the clock itself, which plot the times in the correct places as though the card were a piece of graph paper.

In essence, the time of day determined the punch location on the card, which wasn’t a punch in the hole punch sense, but a two-tone ink stamp from a type of bi-color ribbon you can still get online.

There’s a date wheel that selects the row for the given day, and a time cam to select the column. The early time clocks didn’t punch automatically — the worker had to pull a lever. When they did so, the mechanism would lock onto the current time, and the clock would fire a single punch at the card at the given coordinates.

Modern Time

By the mid-century, time clocks had become somewhat simpler. No longer did the machine do the plotting for you. Now you put them in sideways, in the front, and use the indicator to get the punch in the right spot. It’s not hard to imagine why these gave way to more modern methods like fingerprint readers, or in my case, mag-stripe cards.

This is the type of time clock I intend to buy for myself, though I’m having trouble deciding between the manual model where you get to push a large button like this one, and the automatic version. I’d still like to build a time clock, too, for all the finesse and detail it could have by comparison. So honestly, I’ll probably end up doing both. Perhaps you’ll read about it on these pages one day.

The Issue With Wii U Gamepads and How to Clone Them

How hard would it be to clone the Wii U gamepad, the quirky controller with its unique embedded screen? This is the question that [MattKC] faced as he noticed the complete lack of Wii U gamepad replacements from either Nintendo or third-parties, leading him down the rabbit hole of answering said question.

Although unloved and even despised in compared to the Nintendo Wii, the Wii U was a solid system in its own right. One of its interesting additions was the gamepad controller, whose screen games used for features like a private screen during multiplayer and 3DS-like map screens. Its main weakness is however that the Wii U gamepad was considered an irreplaceable part of the console, which is obviously not fun if your gamepad breaks and your console along with it.

The Wii U console and gamepad communicate via 5 GHz 802.11n WiFi, but in order to deter other parties from simply hopping onto the access point, Nintendo slightly obfuscated this WiFi standard. Specifically the WPA authentication was modified by a byte swap in the PTK, rendering every existing WiFi stack incompatible with the Wii U.

Knowing this, the key is to use a platform that allows one to pre-break WPA in a similar fashion, such as is possible on e.g. Linux and BSD. Along with the use of the hilariously insecure WPS that is triggered when the gamepad’s sync button is pressed, this enables one to connect a modified Linux system to a Wii U console. After this the console starts sending h.264 (AVC) encoded video to the ‘gamepad’, and a binary packet can be sent back with the controller inputs.

Suffice it to say that this finding was immediately turned into a GitHub project called Vanilla Wii U, that enables a Steam Deck to be used as a gamepad, as well as any Linux – and presumably BSD – system with a compatible WiFi adapter. This latter point is key, as the non-standard authentication method has to be bypassed in software. This means for example that an un-modded Nintendo Switch cannot be used either.

The technical challenges combined with the systems relatively low popularity explain why third-party gamepads never appeared. However, now that the Wii U is a retro console, these efforts are essential for keeping these consoles working. We’d love to see the PlayStation Portal get modded into being a Wii U gamepad, since it’s basically a more limited clone of the same concept.

Vittimizzazione secondaria, Confartigianato Brescia e Lombardia Orientale dà gilet gialli a chi si sposta a piedi o in bici 🤦🤬

Spettacolare esempio di #victimBlaming: se un automobilista ti investe, è colpa tua che non ti sei fatto vedere. Questo il messaggio sottinteso di questa "campagna". L'altro messaggio è che in strada l'auto comanda, chiunque altro è ospite (indesiderato).

Non si capisce quindi come sia possibile che almeno 30 persone siano morte in cantieri stradali(qui l'articolo di asaps), che chiaramente sono visibili e segnalati, e dove il personale usa abiti coloratissimi e super riflettenti.
Infatti Autostrade per l'Italia deve fare campagne per pregare gli automobilisti di non ammazzare i suoi lavoratori, e l'azienda francese equivalente fa una mostra itinerante con i suoi veicoli (gialli fluorescenti!) colpiti durante i cantieri (qui per più informazioni), 24 in 6 mesi

"Rallenta, il mio papà lavora in autostrada"

Bisogna fare una campagna per chiedere agli automobilisti di non ammazzare chi lavora sulle strade? Di rispettare, non solo il codice, ma anche il buon senso?

Ebbene sì. Perché chi lavora nei cantieri è concretamente a rischio, nonostante gli avvisi, i cartelli, le luci.

Credo che la campagna francese per proteggere i lavoratori stradali sia molto più efficace...
