[JohnSL] And his friends both have injection molding machines. They decided to compare the aluminum molds used with some 3D printed molds usually made with a resin printer. They used two different resins, one on each side of the mold. You can watch a video of the results below.
One half of the mold used ordinary resin while the other side used a resin that was made to hold high temperatures. As you might expect, low-temperature resin does not stand up well to molten plastic. However, the high temperature resin did somewhat better. It is understood, however, that an aluminum mold emits more heat from the plastic which is helpful in the molding process.
Although higher temperatures – and more expensive – resin seems to have a better hold. Of course, it was to test. In real life, you want to use the best resin.
Not surprisingly, resin molds did not last nearly as long as proper molds. After 70 shots, the mold was worn outside of what you want to use. So it’s not necessarily something you want to use to run a real production, but it should be enough for a quick prototype before you go into the cost of making the right mold.
We wonder if there are any other strategies to get better results. A comment from [TheCrafsMan] Suggests that clear resin cures UV better, and it can give better results. In fact, the video has a lot of interesting comments from people who have different experiences trying to do the same thing
If nothing else, it’s always interesting to see the match cut through the aluminum around the 15-minute mark. If you don’t already have an injection molding setup, you can always create one. We have seen multiple designs.
Night Vision projects are great, and the hardware available for the fancy is getting better and better. [Just Call Me Koko] The 3D printed enclosure mounted on a helmet shows exactly the same build using four low-light, IR-sensitive cameras, four displays and four lenses. Why four? Well, mounting two cameras and a display in each eye is the easiest way to see a wide field and for bonus points, it certainly looks extra weird.
At its heart, each of the four parts is the same. A Foxeer Night Cat 3 camera is mounted on the front, its output is directly connected to a 2 ″ diagonal NTSC / PAL display, and a DCX (double convex) lens on the back has a diameter of 38 mm with a focal length of 50 mm. Add a printed perimeter, and the result is a monocular night vision display. Do this three more times and arrange them around the eyeballs, and someone can create a night vision system with a panoramic view that probably only takes one A little Being used.
How well does it work? [Just Call Me Koko] Some walk around and try to practice certain goals while wearing them, and conclude that they have almost no clarity of the actual deal (320 × 240 resolution display limits the details), they work fairly well for what they do. Also, the cost of parts is a small fraction of the cost of the actual thing, making it a pretty enjoyable project in the end.
The kind of hardware available to hobbyists today makes this type of night vision project accessible, but there is always a good old high-voltage analog system.
I have a friend, let’s call him Joe, who runs a small restaurant and is really upset about the recent stock market crash. I can’t blame him. We are in the bear market now. It’s ugly. So, what does Joe want to do? He wants to take some of his assets out of the market and bet on everything – God help us – in a desperate attempt to keep his business of cryptocurrency going.
No! Not only that!
It’s literally jumping into the fire from a frying pan. Yes, I am a crypto-cynic. As far as I’m concerned, Bitcoin, Dodgecoin, Etherium, all cryptocurrencies, is a big deal.
Investing company money in crypto is bad enough, but many business owners are considering adopting it as an alternative method of payment – virtually, for scandal.
You would think that General Gers would just go in and buy what you’re selling, wouldn’t you? Well, how skilled are you at setting up a digital wallet? Especially for a mythical coin that is not regulated, rising and falling like a roller coaster and adding levels and levels of complexity and safety concerns. Cryptocurrencies are a major pain to track in your books. Ask your accountant, he will tell you.
Are you sure you want to get around this thing?
Some crypto believers also seem to be realizing this. Bitcoin hit a new 18-month low and dropped nearly 70% from its record high of $ 69,000 in November 2021. As I write, Bitcoin is falling towards 20,000.
Even large cryptocurrency exchange platforms are in trouble. Coinbase cut 18% of its workforce on June 14, or about 1,100 jobs. Meanwhile, Coinbase owners Co-Founders Brian Armstrong and Fred Ehrsom, President and COO Emily Choi and Chief Product Officer Surjit Chatterjee, have literally cashed out. Money, not crypto, is about $ 1.2 billion in revenue from stock sales.
Another top crypto exchange platform, Celsius Network, has closed its virtual doors. Good luck getting your money back!
So, my friend Joe is back. A small restaurant is always a chance business in any economy, and he has had real problems hiring and hiring staff. So he hopes to be able to quickly convert a declining stock portfolio into cryptocurrency, win big, then cash out to keep his business afloat with earnings.
This will not work. She knows I feel that way. But he is bound and determined.
One of my oldest financial rules – and as far as people go for companies – is that something that looks too good to be true is good to be true. In the 2000s, I had friends who were convinced that Bernie Madoff would be able to deliver a 20% return every year forever. In the largest register scheme so far, Madoff admits he has not actually been in business since the early 1990s. It was all a conf.
But so many people want to believe in magic money. We think that if we lay our hands on that swan laying golden eggs, buy the right tulips, trust the right Miracle Man, or invest in wonderful, mysterious cryptocurrencies, we will be rich. And all our problems will be solved.
I’m sorry. It doesn’t work that way. It will never happen.
Speaking at a recent TechCrunch conference, Bill Gates said that non-fungible tokens (NFTs) are “based on a 100% larger fool theory.” It is true that the price of overly valuable assets will rise unless enough fools are willing to pay for them. He doesn’t believe that “expensive digital pictures of monkeys” are good investments. Gates was not so strict about cryptocurrencies; He said “a farm where they have output, or like a company where they make products.”
For once Gates and I agreed on something. No matter how much financial trouble you or your business may face, Crypto or NFT Snake Oil will not save you. Hard work and real investment is your only real hope. It was the same as it was.

By 2027, India will have 500 million 5G subscriptions
Latest Ericsson Mobility Report – 22nd Ericsson’s version of Network Traffic Insights and Forecasts – India says 5G is expected to account for about 40 percent of all subscriptions by 2027. Globally, 5G is forecast to be about half of all subscriptions by 2027, topping 4.4 billion subscriptions. .
In India, mobile broadband is the foundation on which the government’s ‘Digital India’ initiative will be implemented. Mobile networks in India continue to play an important role in driving social and economic inclusion, as service providers in India prepare to launch 5G this year. 4G is the dominant subscription type driving connection increase in India. Although 4G contributes about 68% of total mobile subscriptions in India, its contribution is expected to drop to 55% by 2027, a release from Ericsson said.
Following the introduction of 5G in India, 4G subscriptions are forecast to decline to an estimated 700 million annual subscriptions in 2027 due to customers shifting to 5G. Commercial launch of 5G network is planned in India in the second half of 2022, with advanced mobile broadband expected to be the primary major use. 5G will represent about 39 percent of mobile subscriptions in the region by the end of 2027, with about 500 million subscriptions.
India has the second highest average data traffic per smartphone worldwide. It is projected to grow from 20GB per month in 2021 to about 50GB per month in 2027 – a CAGR of 16 percent, the release said.
73% of sellers in India rely on sales technology at least once a week: report
In addition to disrupting the Covid-19 epidemic sales process, about 73 percent of vendors surveyed are using the technology at least once a week to gain access to real-time data to drive sales, a report said. Companies are increasing their appetite for data-driven insights to better measure buyer intent and drive more sales, especially in the ongoing ‘great reshuffle’ when buyers and sellers are constantly considering changing roles, according to LinkedIn’s ‘APAC State of Sales 2022’. The sixth edition of the report.
In fact, more than eight out of 10 (84 per cent) sales professionals in India have lost at least one contract to a key decision-maker in the last year alone. Therefore, access to proper Intel has become mission-critical for sales functions across the board, the report said.
To avoid these reactions, three out of four vendors (73 percent) in India are now using sales technology to get accurate real-time data access at least once a week, indicating a growing priority for CRM systems and sales intelligence tools in the industry, it said.
This India version of the APAC State of Sales 2022 report is part of the Global State of Sales Project, which surveyed approximately 15,000 buyers and sellers in 11 countries, including Australia, Brazil, Canada, France, Germany, India, Mexico, and the Netherlands. Singapore, United Kingdom and United States. The report contains responses from 750 buyers and 750 sellers in India
AI, ML most important technology for business resilience: survey
A10 Networks has released a global survey highlighting the challenges and priorities of enterprise organizations in today’s post-epidemic era, as we learn to live with COVID-19 and how it shapes future technology requirements.
In terms of investment priorities, artificial intelligence and machine learning have undoubtedly come a long way, with 47% of Indian enterprise firms saying they have deployed these technologies in the last 12 months. In addition, 34 percent say they have installed IoT devices to help business functions, a release from the A10 network said.
Interestingly, while artificial intelligence and machine learning have scored the most for Indian respondents, 5G technology has followed, and a significant proportion are also looking at installing IoT devices to assist in business functions.
Of the 250 enterprise companies surveyed in India, almost all (97 per cent) showed a high level of concern about all aspects of enterprise digital resilience, the release said.
The report, entitled ‘Enterprise Perspective: Zero Trust, Cloud and Remote Work Drive Digital Resilience’, is based on feedback from 2,425 professionals who work on network infrastructure, security and cloud migration in companies across the United States, Southern Europe and the United Kingdom. , Germany, India, the Middle East, Benelux, Eastern Europe, Asia Pacific and the Nordics.
Pharma companies increase cyber security investments by a minimum of 25-30%
With an increased focus on digital transformation, Indian pharma companies are prioritizing data security, a Deloitte Touche Tohmatsu India LLP and Data Security Council of India report found, Indian pharma taking digital leap – what does this mean for cyber security? The report further states that ransomware attacks and IP and data theft were top cyber security concerns for the sector both in India and globally.
DSCI and Deloitte conducted more than 25 expert discussions between August 2021 and March 2022, where top pharma companies and industry experts, both in the world and in India, shared their views on the vibrancy of the sector and the growing focus on cyber security.
For the top pharma companies, cybersecurity investments grew by at least 25 to 30 percent between 2019 and 2021. The growing number of epidemics and targeted attacks has prompted certain pharma companies to double their cyber security investments in the last 18 months, according to a release from Deloitte India.
As part of the cyber security strategy, data security and resilience, identity and access management, OT security, offensive security capabilities and even better threat detection and response are some of the focus areas for pharma companies in India. In addition, 70 percent of leading pharma companies have shifted their focus to a zero-confidence approach with the need for a clear roadmap over the next two years around networks, data and access, the release said.
India’s investment in AI will exceed 80 880 million by 2023: NASSCOM
Investment in India’s artificial intelligence capabilities is growing at a CAGR of 30.8 percent and is set to reach USD $ 881 million by 2023, according to the latest report from NASSCOM’s AI Acceptance Index.
Global AI investment has doubled in the last year, but India’s share of global investment has remained at 1.5 per cent, the report said. India started from a lower base than its global counterparts and despite its high growth, the country will represent only 2.5 per cent of global investment in 2023.
AI will add USD $ 450-500 billion to India’s GDP by 2025. More than 60 percent of that is expected to come from consumer goods and retail, banking, financial services and insurance, energy and industry, automotive domains, manufacturing, and healthcare, the report said.
NASSCOM, with EY, surveyed about 350 enterprises The survey found that about 65 percent of companies defined AI strategies at the functional or enterprise level. India’s AI maturity stands at Enthusiast, the second level of four-stage adoption assessment.

Head for the mountains !! We are all destroyed! You can at least get this idea from the headlines about monster earth-facing sunspots this week. Although the size of any sun spot like the AR3038 is likely to double in a few days, the chances are very low that it will cause problems on Earth. One of the best sunspots this class can handle is an M-Class solar flare, which usually only causes radio blackouts on poles and can cause radiation problems for ISS crews. No, this sunspot probably won’t kill us all. But then again, it’s the 2020s, and almost everything seems as bad as it can be.
Speaking of bad results, it is a pity for poor Sonos customers and their ongoing battle with the company’s strange “glosses”. For whatever reason, customers are getting shipments of Sonos products that they have never ordered, at least one customer has shipped a product worth 15,000. Customers reported ordering five Sonos items, but the company deemed it appropriate to fill the order six times with the product in their apartment. Sonos doesn’t seem to be doing much to fix it; When offering the customer a free shipping label for returning the product, they were expected to scrape the packages to a UPS store. And then there’s the money – Sonos has charged the customer for all the unstructured products, and won’t refund until all are refunded.
If you’ve ever wondered just what the signals above and below your line look like, you’ll want to watch this video Double A Labs. Using an RTL-SDR dongle and some spectrum analyzer software they test the RF signals on the cable with some interesting results. The first 11 minutes or more of the video is dedicated to setting up the hardware and software, although there are some interesting things about broadband network architecture in the beginning. The scans are interesting – you can definitely watch 6-MHz quadrature amplitude modulation (QAM) digital channels. We were surprised to learn that these start from the band around 108 MHz FM. There were a few small flashes hidden within the spectrum, such as two unmodulated analog TV carriers in one place, and the fact that the 41 6-MHz QAM channel has jammed more than 400 virtual channels. Broadband really.
In a related note, we found a tip in an RF design series on YouTube this week that is pretty extensive to watch. It covers everything from filters and impedance matching to RF oscillators and amps. Each video is 15 to 30-ish minutes long, so quite digestible, and the production quality is good. If you want to speed up the Dark Arts, you might want to check it out.
And finally, if none of the above gives you a fancy tickle, or if you really need to relax, you might want to spend half an hour watching an analog plotter do its job. It comes from our friend CuriaSmark, who recently repaired the classic Hewlett Packard 7035B XY recorder, a beautiful 1960s design with some interesting features. The main one is the use of photocopier to deal with DC offset input. Mark explains it all in the original teardown and repair videos, we have nothing but the slow Cartesian dance of the pen (almost) in a never ending Lisajas pattern. It is very soothing.
Douglas Engelbert’s 1968 “Mother of All Demos” introduces the world to a whole new technology that we recognize today, the most notable being his great invention, the computer mouse. However, MOAD also features things like cut-and-paste text editing, a point-and-click interface, video conferencing, and even online collaboration. From Google Docs. An invention has been shown that for some reason could not stand the test of time. Corded keyboard: An input device where five keys can be pressed simultaneously in different combinations, similarly you can play the chord on the piano.
Although there have been several attempts over the years to bring new life to the “cord”, it has failed to gain mainstream appeal and remains a curiosity today. That makes it a natural fit for Strange input and strange peripheral Competition, as we can see [Russ Nelson]The submission is called the Engelbert Cassette, which aims to create a modern 3D printed cord that serves Engelbert’s purpose.
It is important to note that the corded keyboard does not mean just an extra set of five keys. Instead, Engelbert showed a clever interplay between the cord and the mouse: a complete 8-bit input device could be created by combining the five keys under his left hand and the three mouse buttons on his right. [Russ]Its device has a USB host interface for connecting a USB mouse as well as a USB client interface that presents itself as a combination mouse / keyboard device on the PC.
The brain of the device is made up of a Teensy 4.1, which reads the codes transmitted by the mouse as well as the top five keys. If one or more keys are pressed together with the mouse button, a keyboard code related to Mapping Engelbert’s original keycode is generated. We wonder how practical this whole setup will be in real life; Looks like something you have to try to figure out. Fortunately, all the schematics, code and STL files are available on the project page, so with a little effort you can set up your own MOAD on your desk today.
We’ve featured a few corded keyboards on these pages; Spring like Pico Cord, Cordy and BAT mind. If you’re looking for an overview of Engelbert’s stunning presentation, check out our part in the Mother of All demo 50 years later.
