Playing Star Wars Outlaws sparked an idea with [3DSage]: why not recreate the game’s wrist communicator as a functioning gadget? Inspired by the relatively simplistic design, he and his friend Ben set out to build their own device to take to Galaxy’s Edge in Disneyland. Armed with an arsenal of tools—3D printers, CNC machines, and soldering irons—he aimed to turn imagination into reality.

After ordering multiple walkie-talkies, they meticulously tested each one for audio quality, circuit board size, and compatibility with custom components. The ‘world’s tiniest walkie-talkie’ had potential but demanded creative modifications, including disassembling and resoldering components. They crafted their own circuit board and designed a 3D printed housing to fit both electronics and style. For the finishing touch, they weathered the device with paints and even glow-in-the-dark accents, making it authentic to the Star Wars universe. Even Chewbacca himself gave one a thumbs-up!

Weathering goes a long way towards creating a convincing prop — it can turn a bundle of pipes and some foam blocks into a movie-ready WWII machine gun.

‘Tis the season for holiday hacks, and [Ben Emmett] is here to remind us that we don’t necessarily need a fancy microcontroller in order to make flashy fun things happen.
Smoothing down the copper traces with a guitar pick.
Take this Christmas tree for example, which uses a 555 timer and a CB4017 decade counter in order to drive some blinking LEDs. The ICs are through-hole, making the circuit fairly accessible to new players, but there are a few SMD components that need soldering as well. (More on that later.)

Here, the 555 acts like a clock and drives a square wave. Using the clock as input, the decade counter toggles the output pins one after the other, driving the LEDs to blink in turn. Since there are only eight lights, there is a pause in the light-up pattern, but that could be fixed by wiring decade counter output #9 to the reset pin.

Although function was the main focus circuit-wise, [Ben] managed to lay the traces in the shape of a Christmas tree, which looks great. Having done a similar project in the past, he discovered that the craft cutting machine prefers thick traces and wider spaces between them. This is largely why [Ben] chose to use through-hole ICs.

After laying everything out in KiCad, [Ben] exported the copper layer image for use on the cutting machine. Once it was all cut out, he put it on transfer tape to weed out the extra copper, and get the traces onto cardstock, the final substrate.

This is such a fun project, and we love that the CR2032 that powers it also acts as the stand in its vertical holder. Hit up GitHub if you want to make one for yourself. Want something even more 3D? Check out this hollow tree we saw a few years ago.

We all carry touch screen computers around in our pockets these days, but before the smartphone revolution, there was the personal digital assistant (PDA). While it wasn’t a commercial success, one of the first devices in this category was the Apple Newton. Today they’re sought after by collectors, although most of the ones surviving to this day need a bit of rework to the battery pack. Luckily, as [Robert’s Retro] shows, it’s possible to rebuild the pack with modern cells.

By modern standards, the most surprising thing about these battery packs is both that they’re removable and that they’re a standard size, matching that of AA batteries. The Newton battery pack uses four cells, so replacing them with modern rechargeable AA batteries should be pretty straightforward, provided they can be accessed. This isn’t as easy, though. In true Apple fashion the case is glued shut, and prying it apart can damage it badly enough so it won’t fit back in the tablet after repair is complete. The current solution is to cut a hatch into the top instead and then slowly work on replacing the cells while being careful to preserve the electronics inside.

[Robert’s Retro] also demonstrates how to spot weld these new AA batteries together to prepare them for their new home in the Newton case. With the two rows fastened together with nickel strips they can be quickly attached to the existing electrical leads in the battery pack, and from there it’s just a matter of snapping the batteries into the case and sliding it back into the tablet. If you’re looking for something a bit more modern, though, we’d recommend this Apple tablet-laptop combo, but it’s not particularly easy on the wallet.

This week on the big 300th episode, Hackaday’s Elliot Williams and Kristina Panos teamed up to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. So basically, business as usual.

First up in the news: it’s time for the Hackaday Europe 2025 call for proposals! Do you have a tale of hardware, firmware, or software that must be shared with the Hackaday crowd? Then this is your chance to regale us with a 20- or 40-minute talk. You know we love to hear new voices, so be sure to consider proposing a talk.

On What’s That Sound, it’s a results show week. Congratulations to [Kelvin] who was one of many that correctly identified it as the Wii startup sound. Kristina will just be over here with her Pikachu64 with the light-up cheeks.

Then it’s on to the hacks and such beginning with a rather nice reverse-engineering of the PS1, which surprisingly did it with a two-sided board. Then it’s on to a smartphone home server, magic eye images in a spreadsheet, and the math behind the music of 80s. Finally, we talk about disc cameras, the hovercraft revolution, and a whole mess of keyboards.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

(AGENPARL) – mer 11 dicembre 2024 MILLEPROROGHE, COLUCCI (M5S): SU AUTONOMIA E LEP GOVERNO PERSEVERA E VA CONTRO CONSULTA
ROMA, 11 dic. – “Nel testo bollinato del decreto Milleproroghe all’articolo 16 il governo trasferisce presso il dipartimento per gli Affari regionali e le Autonomie, quindi al ministro Calderoli, l’attività istruttoria per la determinazione dei livelli essenziali delle prestazioni (LEP) e dei relativi costi e fabbisogni standard, fino al 31 dicembre 2025. Quindi, il Governo persevera nell’errore di avocare a sè la determinazione dei Lep, calpestando il Parlamento e soprattutto la Corte Costituzionale che, nella recente sentenza sulla legge per l’Autonomia Differenziata, ha bocciato questa possibilità. Vorremmo anche capire cosa significa che l’attività istruttoria è trasferita “presso” e non “al” dipartimento, il Comitato per la determinazione dei LEP, presieduto dal prof. Cassese, è stato licenziato o semplicemente trasferito presso il Ministero? Sarebbe doveroso il suo scioglimento, a seguito della sentenza della Corte Costituzionale che ha bocciato la legge Calderoli e le collegate norme contenute nella legge di Bilancio 2023. In ogni caso questa contenuta nel dl Milleproroghe è un’operazione a dir poco spregiudicata, tenuto conto che la legge Calderoli è stata bocciata dalla Corte in tutti i suoi pilastri portanti, e lo è ancor di più se si considera che l’attività istruttoria si riferisce alla determinazione delle sole materie Lep e non anche, come pure ha stabilito la Corte, delle materie non Lep nelle parti in cui incidano su diritti sociali e civili. E’ proprio il caso di dire che non c’è peggior sordo di chi non vuol sentire. Al governo e alla maggioranza lo hanno ricordato tantissimi cittadini che hanno firmato per cancellare l’Autonomia, poi la Consulta con la sentenza che smantella la legge Calderoli. Se vogliono perseverare, prenderanno altre batoste e purtroppo a pagare saranno i cittadini che assistono a questo scempio istituzionale che può avere drammatiche ricadute sulla loro vita quotidiana”.
Lo afferma il capigruppo M5S nella commissioni Affari Costituzionali della Camera Alfonso Colucci.
