Sometimes you spend so much time building and operating your nuclear fusor that you neglect the creature comforts, like a simple fusion control profile or a cellphone app to remote control the whole setup. No worries, [Nate Sales] has your back with his openreactor project, your one-click fusion solution!

An inertial electrostatic confinement (IEC) fusor is perhaps the easiest type of fusion for the home gamer, but that’s not the same thing as saying that building and running one is easy. It requires high vacuum, high voltage, and the controlled introduction of deuterium into the chamber. And because it’s real-deal fusion, it’s giving off neutrons, which means that you don’t want to be standing on the wrong side of the lead shielding. This is where remote control is paramount.

While this isn’t an automation problem that many people will be having, to put it lightly, it’s awesome that [Nate] shared his solution with us all. Sure, if you’re running a different turbo pump or flow controller, you might have some hacking to do, but at least you’ve got a start. And if you’re simply curious about fusion on a hobby scale, his repo is full of interesting details, from the inside.

And while this sounds far out, fusion at home is surprisingly attainable. Heck, if a 12-year old or even a YouTuber can do it, so can you! And now the software shouldn’t stand in your way.

Thanks [Anon] for the tip!

There’s nothing more guaranteed to excite a grizzled old railway enthusiast than the sight of a steam locomotive. The original main-line rail propulsion technology still clings on in a few places, but for practical purposes, it disappeared a lifetime ago. It’s interesting then to hear of a brand new steam locomotive prototype being considered for revenue freight use on British metals. Is it yet another rebuild of a heritage design to be used for enthusiasts only? No, it’s an entirely new design with nothing in common with the locomotives of the past, as [Terrier55Stepney] tells us in the video below the break.

Gone is the huge boiler and reciprocating pistons of old, as indeed is the notion of boiling anything. Instead, this is a steam turbine, nothing like the 1920s and 30s experiments with conventional locomotives, nor even the Union Pacific’s oil-fired condensing turbo-electrics. The new idea here from the British company Steamology is to create steam directly from the combustion of hydrogen in a series of small modular steam generators, and the resulting prototype turbo-generator will replace the diesel engine in a redundant British Rail class 60 freight locomotive. It’s unclear whether it will incorporate a condenser, but since it has no need to retain the water for a boiler we’re not sure it would need one.

Prototype locomotives featuring new technologies have a long and inglorious history of not making the grade, so while this is definitely an exciting and interesting development we’re not guaranteed to see it in widespread use. But it could offer a way to ensure a low-carbon replacement for diesel heavy freight locomotives, and unexpectedly provide engine upgrades for existing classes. The fact it’s technically a steam locomotive is incidental.

These days, even hobbyist multi-rotor aircraft are capable of carrying considerable payloads. For example, the test rig that [Brian Brocken] recently put together should be able to loft more than 80 pounds (36 kilograms) without breaking a sweat. That would be a whole lot of camera gear or other equipment, but in this case, he’s planning on carrying something a bit more interesting: a full-scale foam DeLorean.

We first covered this project in December of last year, when [Brian] first started using a massive robotic arm to carefully cut the body and individual parts of the car out of expanded polystyrene foam. He estimated at the time the body should weigh in at less than 30 lbs (14 kg), so he’d need to build a quadcopter with a maximum lift of roughly twice that much to keep the performance where he wanted it.

In the latest update to the Hackaday.io project page, [Brian] goes over the work that’s been done since we first got a glimpse of this incredible build. Improvements have been made to the motorized flaps and slats that cover up the front and rear motors when not in operation. The DeLorean’s iconic gull-wing doors have also been recreated, although in this case they’re motorized.

But the real news is the prototype airframe. Made of aluminum and 3D printed components, [Brian] is using it to get a feel for how much thrust can be expected from the motors, as well as provide some early numbers for the eventual PID tuning that’ll be needed to get the car flying smoothly. Unfortunately, there’s a bit too much flex in this version of the frame — [Brian] says that a later carbon fiber version will not only be more rigid, but also shave off a few more precious pounds.

We’re just as eager as the rest of you to see the first flight of this ambitious build, so stay tuned for the next update.

Readers of a certain vintage will no doubt remember that for a brief time, some alkaline batteries came with a built-in battery tester. Basically, you just pushed really hard with your fingernails on the two ends of the strip, and it either lit up the little strip (or didn’t if it was dead), or made the word ‘good’ appear if energized.

But those days are long gone. What you need now is to either grab the voltmeter, stick out your tongue, or build yourself a battery-testing business card. Even the normies will enjoy this one, mostly because LEDs. Forty-seven of them to be exact, which will come to life and demonstrate that [Greg] is capable of making working electronic gadgets. No way does this card end up at the bottom of a desk drawer.

As far as grasping the batteries goes, [Greg] had several ideas, but ultimately landed on pogo pins, which we think is a fabulous solution. Be sure to check out the neat interactive BOM, somewhere in the middle of which is the CH32v003 RISC-V microcontroller. In the video after the break, you can see [Greg] using a Flipper Zero to program it.

For most of our prototype, hobby, or one-off electronics projects it’s perfectly fine to use a development platform like an Arduino Uno or something to that effect. They’re both easy to program and easy to wire up to projects without breaking the bank. But if you step into an industrial setting where reliability is paramount even in places that are noisy, vibrating all the time, hot, or otherwise unpleasant for electronics, you’ll want to reach for a programmable logic controller (PLC) that are much more robust. There is actually a PLC from Arduino, and if you want to dip your toes into the PLC world then take a look at this drum kit based on the Arduino Opta.

With the PLC at the core of the build, it’s on to making the drumming mechanisms themselves. For that, project creator [JC Audio] is using a series of solenoids attached to camera mounts with a custom 3D printed part that allows for quick assembly and disassembly so he can get the positioning of each drum sound just right. The high hat is taken care of by the noise of an internal solenoid, with the other drums striking various real drums and other solid objects in his shops. The solenoids themselves are driven by a solid-state relay expansion module to ensure there’s enough power

While the build doesn’t sit inside a factory and run for years at a time, a musician’s stage is certainly a rough enough environment that we might reach for a PLC over a standard development board for its benefits. The code for this project is available as well at the project’s GitHub page for those looking for a more advanced timekeeper to play along with their music practice, and for more details on why you might choose a PLC for your project take a look at this Arduino vs PLC showdown from a few years ago.

Un sistema di commercio illegale di pesticidi e fertilizzanti contraffatti e vietati, potenzialmente pericolosi per la salute dei consumatori, è stato fermato dalle autorità rumene e italiane.
#Eurojust ed #Europol hanno favorito la costituzione e supportato la squadra investigativa comune formata da Forze di Poliza dei due Stati (#JIT). Nel corso di una serie di azioni in entrambi i paesi sono state raccolte prove di frode su larga scala, falsificazione ed evasione fiscale e un sospettato è stato arrestato.
Il commercio di tutte le sostanze è stato vietato nell'Unione europea (#UE) perché potrebbero essere pericolose per gli utilizzatori e i consumatori in quanto contengono dosi elevate di sostanze attive.
I sospettati importavano illegalmente i prodotti dalla Cina e da Singapore, ma li vendevano come fertilizzanti e pesticidi bio o organici, utilizzando etichette false. I sospettati vendevano anche prodotti contraffatti fingendo che fossero prodotti biologici legittimi.
Tra febbraio e maggio 2023, le autorità doganali rumene hanno individuato tre spedizioni sospette provenienti da paesi terzi. Successivi controlli da parte delle autorità fitosanitarie hanno confermato che si trattava di prodotti contraffatti o vietati, utilizzando etichette falsificate. Ulteriori indagini e perquisizioni in #Romania hanno dimostrato che dietro le attività illegali c'era un gruppo criminale organizzato, composto da cittadini rumeni e italiani che hanno rilevato aziende esistenti in Romania o registrato nuove società commerciali per la vendita dei prodotti in Italia. A questo scopo sono stati utilizzati moduli di dichiarazione falsificati.
L'Autorità giudiziaria italiana ha raccolto numerose prove sulla destinazione al mercato interno delle merci illegalmente introdotte in Romania e ha individuato gli indagati che avevano favorito il traffico illecito di prodotti agricoli provenienti dall'Italia.
Su richiesta delle autorità coinvolte, all’inizio di quest’anno Eurojust ha contribuito alla creazione e al finanziamento di una squadra #SIC .
Durante le attività operative, Europol ha inviato un esperto sul campo per effettuare un controllo incrociato delle informazioni operative in tempo reale e fornire agli esperti eventuali orientamenti e supporto tecnico. Questo sostegno ha portato a una serie di azioni coordinate in Romania e Italia, durante le quali sono state perquisite dieci località tra Arad, Bucarest, Verona e Napoli, raccogliendo ulteriori prove dei crimini.
Nel corso delle attività, l'Autorità Giudiziaria rumena ha arrestato anche uno degli indagati.
Le operazioni sono state effettuate da:
- Romania: Direzione per le indagini sulla criminalità organizzata e sul terrorismo, Ufficio territoriale di Costanza; Direzione delle operazioni speciali (DOS); Brigata per la lotta alla criminalità organizzata – Servizio dei porti marittimi per la lotta alla criminalità organizzata; Uffici doganali di frontiera Constanta e Constanta Sud
- Italia: Procura della Repubblica di Verona; #NAS #ArmadeiCarabinieri Padova; #Guardiadifinanza Verona
