3D Printing Materials: PLA vs ABS Filaments

3D printing enthusiasts must decide between two popular materials: PLA or ABS filament. There are distinct differences between the two that must be taken into account when choosing the right 3D printer for your needs.

PLA Filaments

PLA (polylactic acid) is a type of biodegradable plastic produced from corn starch or sugarcane. PLA is popular because it is easy to print with and has low warping and shrinking characteristics. This makes it the perfect choice for intricate designs and objects with moving parts, as there is less risk of any distortions occurring during the printing process. It’s also available in a wide range of colors, so you can easily create bright and colorful objects. However, PLA doesn’t have the highest temperature tolerance, making it inappropriate for very hot applications such as electronics enclosures.

ABS Filaments

ABS (acrylonitrile butadiene styrene) is another type of plastic used for 3D printing that has higher heat and impact resistance than PLA filaments. It’s also more durable, so it’s better suited to create stronger parts with longer-lasting performance. However, ABS often requires a heated bed and enclosure to ensure proper bonding and prevent warping due to its higher melting temperature. It’s also more difficult to work with than PLA, so some users may find this material too challenging to use until they gain more experience as a 3D printer enthusiast.

Can AI Beat a Human?

Can AI Beat a Human?The question of whether AI can beat humans is a complex and multifaceted one. In certain specific tasks and domains, AI has demonstrated remarkable capabilities that surpass human performance. For example, in games like chess, Go, and poker, AI systems have defeated world champions and top-ranked players. AI has also shown superior performance in tasks such as image and speech recognition, language translation, and even medical diagnosis.

However, it is important to note that AI is not a monolithic entity with general intelligence comparable to human cognition. AI systems are designed and trained to excel in specific tasks based on vast amounts of data and computational power. While they can outperform humans in these specific domains, they lack the broad and adaptive intelligence that humans possess.

Human intelligence encompasses a wide range of cognitive abilities, such as creativity, intuition, common sense reasoning, empathy, and moral judgment. These qualities enable humans to navigate complex and uncertain situations, make decisions based on context and values, and adapt to new and unfamiliar circumstances. AI systems, on the other hand, operate within the confines of their programming and training data, lacking the inherent understanding and flexibility of human intelligence.

It is also worth noting that there are tasks and domains where humans continue to outperform AI. For example, tasks that require fine motor skills, social interaction, emotional intelligence, and complex physical manipulation are areas where humans still hold a significant advantage.

The potential impact of AI on society raises important ethical and philosophical questions. As AI systems continue to advance, there are concerns about job displacement, privacy, bias, and the overall control and accountability of AI. It is crucial to ensure that AI technologies are developed and deployed in a responsible and ethical manner, with careful consideration of their potential societal implications.

In summary, while AI has demonstrated impressive capabilities in specific domains, it falls short of encompassing the breadth and depth of human intelligence. The relationship between AI and humans is best understood as a collaboration, where AI augments human capabilities in certain tasks, but human judgment, creativity, and adaptability remain crucial in many areas of life.

Home automation with Home Assistant

Home Assistant LogoI’ve been heavily in to home automation for years, starting with my own homebrew projects built with Arduino, Mbed and later Raspberry Pi, the solutions I ended up with were always bespoke and esoteric. 

As time went by I added new products from Hue, Tuya, Smart Life, Ring, Ezviz and others. While these all worked fine, they each had their own app and ecosystem and therefore could not interact with each other. 

A few months ago I found a Raspberry Pi Model 3 that I wasn’t using and started looking at various home automation options that were available.

Enter Home Assistant…

iFrogz Impulse Duo Dual Driver Wireless Bluetooth headphones Review

IMG_0600It’s always nice to be pleasantly surprised by a product. I had the opportunity to play around with the iFrogz Impulse Duo dual driver wireless Bluetooth headphones (not an easy title to get your tongue around). At around £39, these are on the lower end of the pricing spectrum and I am generally wary of companies that start with a small “i” and swap “s” for “z”, so it’s fair to say that expectations were not exactly high.

The headphones were nicely presented in a simple but elegant box and slip cover that does what it needs to do without going overboard. There is no pouch or case included, but you do get 3 sizes of tips. The actual ear pieces are pretty funky looking thanks to the dual 6mm drivers and an unusual mix of materials and textures – they certainly don’t look like regular headphones. Despite the slightly odd shape, they are actually pretty comfortable to wear, although there is a small nub on one side which can sometimes be a little irritating.

 

The earpieces are connected to a small control unit which features a nifty magnetic retention clip, so you can wind the cables around it for neat storage when not in use. The unit houses the battery, Bluetooth system microphone for call handling and offers 3 control buttons. The two volume buttons double as track forward and back controls if you long press them and the centre button activates the play/pause, call answer, power on/off and paring functions depending on how long you hold it for. Simple, but effective. The buttons are quite big, but they do need some deliberate pressure to push them, so accidental activation is not much of an issue. In use, the remote dangles from the earpieces, threatening to pull them out, so you will need to attach it to your clothing. The problem is that the cables are only about 35cm long, so it will need to be clipped to something quite close to your head. The magnetic clip does a decent job at this, although I don’t think it’s quite as good as a traditional clip and there may be a bit of an issue if you don’t have anything to attach it too (so no super tight muscle shirts or boob tubes!).

ifrogz, headphones, earphones, uk, review, dual driver

The box claims a battery life of up to 10 hours and the unit is charged by a micro USB cable (supplied). This is often difficult to verify as you are rarely listening to them constantly for such a long period of time, but in testing, they certainly did seem to hold a charge for a considerable amount of time. When powered on, there is a blue indicator light which blinks periodically. I quickly learned to hate this light, and if you listen to music in bed at night, you will learn to loathe it too. It more closely resembles an emergency distress beacon than an indicator – that thing is bright! The cables are fairly short too, so it’s always going to be close to your head and is almost impossible to ignore. I was almost reaching for the duct tape but ended up finding a small pouch to put it in just to hide it. Yes, it’s that annoying! Not so much an issue during the day of course.

The sound from the iFrogz is what surprised me the most. For the price point, I expected a flat and tinny sound, but thankfully that is far from the case. Sure, they do not have the dynamic range of some of the competition, but I feel that they do punch above their weight. The first thing you will notice is that they are quite bass heavy. This is great for some musical genres, but with others, the mids and highs can seem overwhelmed by the booming resonant bass tones. One of my regular go to testing tracks is “It Won’t Be Long” by Super Collider as it is exceptional for testing tonal balance, bass response/distortion and seeing how much detail is retained. The iFrogz handled it well and did not distort too noticeably at the really low levels, but you could notice the flattening of the upper frequencies. But for £39, this is more than acceptable.

The other aspect it really liked about the iFrogz was when I fired up Youtube and was immediately impressed that there was no noticeable lag time. The sound was well in sync with the visual, something that is often an Achilles heel of Bluetooth headphones, particularly at the cheaper end of the market.

So, good battery life, comfortable, decent sound and under £40, if you want something cheap and functional, it’s hard to knock these.

Brainwavz B200 Audiophile grade earphones review

IMG_0581I must confess that I was not familiar with the brand when I was given word that their latest headphones were coming to us for review. They operate in the audiophile circles of the headphone world, but their aim is to keep the cost of their products at the more reasonable end of the spectrum. When I was given these in ear headphones, all I knew was that they were audiophile grade and cost £156.

The first thing that struck me when I was handed the box is that it smacked of neither audiophile nor £156. It is a pretty basic box with minimal amounts of styling, made from fairly thin card and a plastic tray inside. It looks remarkably like an early DVD box set or an Amiga game. This is not always a bad thing, however. Regular readers will know that I have mixed feelings about packaging. Sure, I like some swish presentation to give a premium feel as much as the next guy, but at the same time, I do not like the idea that a product has its price bumped by £20 just to get a swanky box that will ultimately be thrown out anyway.

Brainwavz, dual, balanced, armature, B200, high performance, audiophile, grade, earphones, headphones, uk

In the box, you get a rather nice, rigid carry case that feels very well constructed, with dividers to house the spare tips for the ear buds. There are 2 sets of small, medium and large tips included plus a bonus set of “premium” memory foam tips that honestly feel kinda like chewing gum. The headphones themselves are extremely lightweight and there is good reinforcement at the joints, but I couldn’t help but think that the wires were worryingly thin. Making tech super lightweight is great, but sometimes it can leave products feeling a little flimsy, even if that is not the case.

After a few minutes of experimentation, I figured out how to wear the headphones and which one went in which ear – yes, I know how to wear headphones – but the B200’s feature a neat design where the cable loops over your ear thanks to a semi rigid sleeve over the wire so you put them in your ear with the wire pointing up. It takes one or two goes to get the technique down, but it’s not tricky. For me, the premium tips were an absolute winner. They feel weird, but once you squish them and push them into your ears, they are incredibly comfortable and do an excellent job of cancelling out ambient noise. The loop design means that the weight of the cable is not applied directly to the ear bud, so there is not the usual battle of earpiece retention vs gravity. The result it that these headphones stay in place exceptionally well. I was able to enjoy a brisk walk on a windy evening and never once had to push the headphones in to keep the fit nice and snug. Brilliant!

As usual, I let the B200’s burn in for a day or two before really testing the sound quality on them. It’s a very natural sound, nicely balanced, which is my personal preference. There is plenty of bass, but it is not an auditory assault like on some sets. Mids and highs are nicely separated with a good amount of crisp detail which gives a satisfying breadth to the sound and again, nothing seems overly forced. The benefit of a neutral sound is that it lends itself well to a wide variety of musical genres and I found that the B200’s handled any track I threw at them in their stride. Listening to podcasts where the focus is on people speaking, the voices do not sound overly bass heavy and resonant which music focused headphones have a tendency to do. These are really nice headphones.

Brainwavz, dual, balanced, armature, B200, high performance, audiophile, grade, earphones, headphones, uk

Brainwavz offers a 24month warranty on the B200’s(“should any problem arise due to a defect in workmanship”) which shows a reassuring level of faith in their products and quality control. This is not something to be underestimated. I do maintain some concerns about how fine the cable is on these headphones and I did notice that they do tangle up quite easily because of the loops, but at least if there is a weakness there, Brainwavzshould look after you and that is reassuring. Whilst they are reasonably priced for headphones at this level, £156 is still a significant chunk of money so a little reassurance is a very good thing!

If you haven’t heard of Brainwavz, I would certainly you encourage you to check them out. They certainly don’t look as flashy as some of their peers, they may perhaps lack some of the prestige feels, but there is absolutely no escaping the excellent performance or the phenomenal comfort of these headphones.

The Brainwavz B200 are for sale on Amazon here for £149.50.
