Raspberry Pi Gets a Production Quality Upgrade
Until version 5 of the Raspberry Pi, any parts that required a hole completely through the PCB required a solder bath. Pi tried to avoid through-hole components as much as possible but used them for connectors. Just placing those parts can be a pain. Pi workers originally did some by hand, but eventually had machines do the work. Still, the solder bath was a pain point. The solution is a process known as intrusive reflow.
'Thanks to our work with Sony, we have eliminated all of the through-hole specific actions from our manufacturing processes,' wrote Raspberry Pi Principal Hardware Engineer Roger Thorton in a post. 'With intrusive reflow, we can now place through-hole connectors using the same pick and place machines we already use on surface-mount parts; this means there is no longer any need for bespoke robotics, or for an additional soldering stage.'

Reflow soldering typically involves a soldering paste flowing under intense heat instead of relying on a solder bath. Raspberry Pi is now working on applying the new process to older generations of the Pi.
The move to intrusive reflow also meant Pi could remove the selective solder bath machinery, reducing its CO2 output. Pi says its CO2 output is down by 43 tonnes (roughly 47.39) per year. The change also means that there is no longer a break in the production process. Overall, it looks like a huge win for the little Pi.
The Raspberry Pi is a tiny computer that fits a range of uses, including business and entertainment. The computer's inexpensive price tag and accessible documentation also make it ideal for teaching (and self-learning) coding, robotics, and even AI. The Raspberry Pi 5 starts at $50.
If you have any interest in seeing just how much the Raspberry Pi can do (and learning about robotics, engineering, and coding along the way, you might want to shell out some extra cash to pick up the PiDog programmable robot kit. It's one of the most interesting robotics kits we've seen.

Amazon Prime Day TV deals for 2025 from Sony, LG, Samsung and others
Amazon Prime Day is here, and it's the perfect time to consider upgrading that old 1080p or first-gen 4K set. While it's been nice to see TV prices fall in general over the years, there's always room for even more discounts. And yes that includes typically high-end technology like OLED and MiniLED screens. We've collected the best Prime Day discounts on sets from Sony, Samsung, LG and others, along with additional deals on media streamers and soundbars. It turns out, you really don't have to spend a ton to nab a solid home entertainment setup that supports 4K HDR and Atmos surround sound. LG OLED Evo C5 (65-inch) for $1,797 (down from $2,700): LG has steadily improved its C-series over the years, and the C5 Evo is its best model yet. In addition to the usual benefits of OLED, it also sports a brightness booster that can help it work well in bright rooms, as well as LG's own 'Perfect Color' technology. It doesn't have quantum dots like Sony and Samsung's OLEDs, but it's also coming in significantly less than those models. The C5 Evo also has a fast 144Hz refresh rate for gaming, as well as support for NVIDIA's G-SYNC and AMD FreeSync variable refresh rate technology. (If you're looking for something larger, the 77-inch model has also been discounted to $2,800.) Sony Bravia 8 II (65') QD OLED for $2,998 (down from $3,500): Sony's top of the line set has everything you'd want in a high-end TV, like quantum dots for improved color and brightness, as well as the inky dark blacks and infinite contrast of a modern OLED panel. You'll always pay a bit of a premium for Sony TVs, but partially that's due to their world-class image processing – in this case, that's handled by Sony's XR chip. (You can also snag the 55-inch model for $2,500.) TCL QM8K (65-inch) QD Mini LED for $998 (down from $1,800): TCL's QM8 sets feature the company's best and brightest Mini LED screens with Quantum Dots. It has an ultra-thin bezel, 144Hz refresh rate for fast gaming and one of the best contrast ratios you'll see outside of an OLED screen. Basically, it's one of the best screens you'll find that's not an OLED. While we think the 65-inch model is a great deal for most rooms, you can also step up to the 75-inch for $1,500, the 85-inch for $2,199 and the massive 98-inch set for $3,000. TCL QM6K (98-inch) QD Mini LED for $1,800 (down from $3,000 MSRP): The QM6K is one of the best deals we've seen on a 98-inch TV under $2,000, and best of all, it's not just a bargain bin screen. It has a bright Mini LED display with quantum dots for enhanced color, and it sports a fast 144Hz refresh rate for gaming. It's also a pretty solid Prime Day deal, coming in much lower than the previous $2,200 low price. (If you don't have the wall space for a nearly 100-inch set, the 65-inch model is similarly great and is down to $550, nearly half off its $1,000 MSRP and $100 off its lowest price. The 75-inch model is also a great deal at $850.) Sony Bravia 5 (85-inch) Mini LED for $2,298 (down from $2,800): The Bravia 5 pairs a super bright Mini LED panel with Sony's XR image processing chip. It won't reach the deep dark black levels of OLED, but Mini LED achieves something close, and it can also get much brighter than OLED panels. That makes this model, as well as any Mini LED TV, an excellent option for bright rooms. (You can also scale down to the 65-inch and 75-inch Bravia 5 for $1,300 and $1,800, respectively. And there's also the truly massive 98-inch model, which is now $1,000 off at $5,000.) Samsung The Frame Pro (65-inch) for $1,899 (down from $2,200): New for 2025, Samsung's Frame Pro sets offer brighter and higher-quality Mini LED panels for a superior TV watching experience. The 65-inch Frame Pro is a great option for most living rooms since it's large enough to deliver an immersive viewing experience, and it also comes with Samsung's wireless One Connect box for less cable clutter. While there's still no OLED Frame TV yet, this Mini LED set is the closest you'll get today. (If you're looking for something larger, the 75-inch Frame Pro is down to $2,699, and the 85-inch is $3,799.) Hisense S7N CanvasTV (65-inch) for $898 (down from $1,300): Hisense's spin on Samsung's Frame sets, the CanvasTV, comes in much cheaper and with a boatload of features. The S7N sports an anti-glare display and art mode, as you'd expect, but there's also 144Hz support for a bit of gaming. It also comes with a slim wall mount so you can hang it on your wall like a genuine work of art. (The 55-inch model is also a great deal at $689, and the 77-inch is down to $1,399.) Amazon Fire TV (50-inch) for $260 (down from $400): Amazon's budget Fire TV sets handle the basics just fine, and at this price the 50-inch model is a compelling deal as a second or third TV set. It supports HDR10 (but not Dolby Vision), and as you'd expect, it also has the Amazon Fire TV OS built-in, giving you access to over 23,000 apps. It also sports Amazon's Alexa Voice Remote to help you find content quickly. (You can also go up and down in size, depending on your needs. The 43-inch model is now down to $220, and it'd be a solid choice for a small bedroom or office.) Hisense QD6 (55-inch) for $240 (down from $380): Hisense is on a roll delivering tons of TV features at a very low cost, and the QD6 line is a prime example of that. It has Amazon's Fire TV and Alexa support built in, and it also supports Dolby Vision and Dolby Atmos. It can even handle a bit of fast gaming with a 120Hz refresh rate. TCL QM6K (55-inch) for $448 (down from $600): TCL's mid-range sets finally fall below $500 for Prime Day, and that makes the QM6K one of the higher quality options in this price range. It features a bright Mini LED panel, a 144Hz refresh rate for gaming and it even includes an Onkyo speaker setup built-in. While it's technically a budget set at this price, it certainly won't look like a low-grade TV. Roku Smart TV (32-inch) for $100 (down from $143): Not every room needs a large TV — this Roku Smart TV is perfect for a small bedroom or office. It's powered by Roku's OS and it comes with a Voice Remote. While it only offers a 720p resolution, that will still look decently sharp on a screen this small. Sonos Beam Gen 2 for $369 (down from $499): Sonos's latest Beam is one of the best mid-range soundbars on the market. It's compact, but it also delivers expansive sound. And it also supports Dolby Atmos through a bit of speaker virtualization. The Beam is also ideal if you've already got Sonos speakers, since you can pair them all together for some household jams (or just bring your TV audio to different rooms). TCL S55H soundbar for $100 (down from $160): At this price, the TCL S55H delivers a ton of audio bang for the buck. It comes with a wireless subwoofer, features auto room calibration and supports virtualized surround sound like Dolby Atmos and DTS Virtual:X. With 220W of power behind its sound, the S55H should be powerful enough to fill most rooms. Sony Bravia Theater Quad for $2,000 (down from $2,500): Leave it up to Sony to do something different in the world of home entertainment. The Bravia Theater Quad are a set of four flat modules, containing a total of sixteen speakers, which deliver truly enveloping surround sound. They're the ideal solution for anyone who wants a theatrical experience, but doesn't want to see gigantic tower or bookshelf speakers in their space. They support Sony's 360 Spatial Sound Mapping, as well as Dolby Atmos and DTS:X. Sony Bravia Theater Bar 9 for $998 (down from $1,400): The Bravia Theater Bar 9 is Sony's most capable self-contained soundbar, with 13 speakers and support for virtualized surround sound with Dolby Atmos, DTS:X and Sony's own 360 Spatial Sound Mapping technology. It's the best option if you want to enjoy your favorite movies and music loud, but also don't want to see speakers all over your living room. (The Bravia Theater 8 is also discounted to $698 and very well-equipped, with 11 speakers and the same surround sound support. ) Sony Bravia Theater System 6 for $568 (down from $770): If you want real surround sound from an actual subwoofer and satellite speakers spread around your room, the Bravia Theater System 6 is a solid choice. It pairs together a soundbar, wireless subwoofer and two rear satellites (connected by a wireless amplifier). It's a great option for apartments and small living rooms where you just can't live with virtualized surround sound. (You can also snag the soundbar on its own for $448, down from $650.) Roku Ultra for $69 (down from $100): Roku's ultimate set-top box is the best streamer for home theater enthusiasts who want to avoid the more expensive Apple TV. It handles every video and audio format you'd want — including Dolby Vision, Atmos and HDR 10+ — and it also comes with Roku's rechargeable Voice Remote Pro. The Roku Ultra is the fastest device from the company, so you can expect to zip around Roku's interface and apps far quicker than the cheaper streaming sticks. Roku Streaming Stick+ for $30 (down from $40): The Roku Streaming Stick+ is the easiest way to bring Roku's robust app selection to any 4K TV. It's a great option for first-generation 4K sets that either had no streaming apps, or are way too slow by now. And it's a great gadgets to bring on trips to maintain access to all of your favorite streaming services. Roku Streaming Stick HD For $20 (down from $30): The basic HD Roku Streaming stick is a solid option for bringing streaming apps to older TVs, which likely don't support 4K or any fancy HDR standards. Sure, it's as no frills as you can get, but for $20 it's worth having a backup streaming device. (or one you won't mind losing during a trip). And if you have an older TV that's still working, it's definitely worth investing a bit to get modern apps. Amazon Fire TV Stick 4K for $25 (down from $50): Amazon's Fire TV Stick 4K is a simple way to add some streaming smarts to any TV with an HDMI port. Alternatively, you can load it up with your favorite streaming apps and bring it on the road – it sure beats fighting with apps built into hotel or AirBnb TVs. As a bonus, you can also play Xbox cloud streaming games when you pair a controller (Xbox GamePass membership required).

These headphones are like the Mighty Ducks of noise-canceling cans — and they're $100 off in the Prime Day sales
Whenever topics turn to noise canceling, they often seem to center on Sony and Bose, but there are some great alternative options available. Case in point: The Beyerdynamic Eventho 300, a pair of great-sounding and comfortable ANC headphones that have just been reduced in the Prime Day sales. The Beyerdynamic Aventho 300 are now down to $299 at Amazon, after a massive $100 discount. That's their lowest price ever. The Beyerdynamic Aventho 300 are a more premium pair of headphones than the competition. Metal hinges, plush earcups, and a protective case that also includes a special bag to keep your headphones really safe. 50 hours of battery is excellent, and the sound is about as epic as you'd expect from Beyerdynamic. This deal brings them down to their lowest price ever. I really like the Beyerdynamic Aventho 300. I like how their design is different from the competition, and I like how brave they are by joining the luxury segment first. Although since their release, other headphones have now made for even higher price points — we're looking at you, Sony WH-1000XM6. The Aventho are a comfortable pair of headphones, albeit with a slightly higher clamping force than some might like. The plus cushioning is very nice though, and the headband is shaped so as to not make too much of a dent on your head. Which is nice if you wear headphones while being bald. The sound is the highlight, as you might imagine, although you'll want to leave the spatial audio portion turned off. It doesn't do much beyond making the headphones sound thin. Battery life is very good as well, with 50 hours on tap to make sure they'll last you for a few days of use. That's more than the Sony and the Bose options as well, bringing another point in favor of the Aventho. This $100 saving makes them a steal this Prime Day — don't look at Sony and Bose, I would think about buying these instead. There are plenty more deals to be had this Prime Day — make sure you check out our Prime Day live blog to make sure you're staying on top of all the latest sales and offers.
