In an earlier post I wrote about the Snettisham Great Torc, and how it had been created by artisans 2000 years ago. Well today I have something even more exciting to share – a video about how these amazingly beautiful objects were made using the simplest tools imaginable. And here it is:
Roughly half way through, the presenter talks about how she experimented with the technique by casting her own ingot of bronze and then patiently hammering it out into a thin piece of wire. The Iron Age artisan who made the torc must have been a master craftsman with a whole bunch of lesser journeymen and apprentices to help with the backbreaking work, but still, can you imagine how long it would have taken? And how many failures there would have been along the way? The skill, dedication and commitment of these craftmen is beyond my comprehension.
Once again, my thanks to Dawn of Dawn Gill Designs for finding this incredible video and sending me the link to it. If you haven’t yet guessed, Dawn is the blogger I call Silversmith because she makes beautiful pieces of jewellery. She’s also my go-to-person when I need information on crafting techniques. -waves at Dawn-
Okay, back to work. Today I upload Vokhtah and its new cover to Lulu! Vokhtah was my first book and the only one I have never been able to physically hold in my hands. Finally getting a print copy will signify the end of a learning curve that began in 2004. So excited. 🙂
No, not kidding. I’ve been doing some research on bats today and stumbled across a youtube site about robot bats. Then..I found another site that had all sorts of robot animals, including that kangaroo I mentioned. 😉
The video clip is broken up into segments, indicated by the small yellow square as shown below:
The first segment is about ants, the second [circled in red above] is about the kangaroo. If you don’t want to watch through the ants, just let the video buffer for a bit then fast forward to that first yellow segment.
And here’s the actual video. 🙂
My thanks to sv3dprinter for this great post about a company that developed 3D printed food for NASA:
I recommend checking the post out as it contains links to other great videos on 3D printing:
If microwaves brought about a revolution in foodprocessing last century, 3D printing will do the same for this century. I love the tech but I think I’ll stick to home cooking. 🙂
As exciting as Elon Musk’s bet, and subsequent giant battery may be, there is a hell of a lot more going on in Australia that never gets a mention. Not sexy enough I suppose. Well, I think micro grids, renewables and batteries are very sexy so have a look at this:
This is the proposed plan for a micro grid in Kalibarri, WA. Kalibarri is a rural community which relies on power coming in via the Geraldton Feeder. Just one single source of power. When that power goes down, Kalibarri goes dark. Kind of hard to run homes, not to mention businesses, without power.
But all that will be a thing of the past once the micro grid is up and running. It will include power from the windfarm as well as power contributed by individual homes running solar panels. All that power will charge a 2 MWH [megawatt hour] battery, and the Geraldton Feeder will be there as well. All that equates to power security for a community that has had anything but. On a national level, the Kalibarri micro grid is also an example of what Australia can do in spite of the idiots in Canberra.

And now a big thank you to Dawn who found out about this development and sent me the URL. Dawn is a Silversmith who loves cheering people up. She would call this a cheeryuppy story and I couldn’t agree more!
Keep smiling, only four more days ’till the weekend. 😀
If you remember how Princess Leia appeared as a ‘hologram’ in the original Star Wars movie, you’ll find this new technology incredibly exciting. Why? Because for the very first time, we have the ability to project an image into space…in real 3D:
I cannot stress the importance of this technology enough. VR is exciting and impressive, but AR – Augmented Reality – will become a part of our lives much, much faster. Why? Because the uses are almost unlimited. Imagine walking down the street and having a full-colour, 3D advertisement step out from the wall and ‘talk’ just to you.
Okay, adverts you can’t escape are probably a terrible example, but what about crafts? Instead of looking up a youtube video clip, you could snap your fingers and have a 3D presentation appear in your workshop, loungeroom, kitchen, whatever. You could look at that presentation from the back, front, side, top or even from the bottom for those tiny details that aren’t normally visible in 2D.
Well, this new volumetric display technology could well be the innovation that allows us to do all that and so much more.
-mumble- Those scientists might want to change the name though. VD just does not have the right ring to it. 😦
I know you’re not supposed to blow your own trumpet but read this:
“…a private company called Paradromics is developing a cortical interface that uses arrays of microwire electrodes to record and stimulate clusters of neurons…”
“..A Columbia University team aims to develop a non-penetrating bioelectric interface that can transmit stimuli directly into the visual cortex…”
Those are just two projects being funded by DARPA which stands for ‘The Defense Advanced Research Projects Agency’. DARPA is an …’agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military’.
‘DARPA-funded projects have provided significant technologies that influenced many non-military fields, such as computer networking and the basis for the modern Internet, and graphical user interfaces in information technology.’

No one’s come up with Kenneth’s ’embalming fluid’ interface yet, so for once I’m ahead of the game. God I love science fiction!
As a long time fan of renewable energy, the latest news about Elon Musk fills me with glee. He bet that he could install a megabattery in South Australia in 100 days, and he’s come in ahead of schedule!
The story began last year when South Australia suffered a massive storm that destroyed infrastructure meant to allow Australian states to ‘share’ energy on a huge network. Due to some market manipulation on pricing, and a toothless watchdog asleep at its post [yes, AEMO I’m looking at you] South Australia suffered crippling blackouts, off and on, for weeks.
As the South Australia government is Labor and had invested heavily in wind farms, the Liberals in the national government went on a renewable energy bashing spree without offering up one, single practical solution. And then Elon Musk spoke up and shamed them all. He said that he could create a mammoth battery capable of storing the energy from the wind farms until needed. Then he bet the cost of the battery – $50 million dollars – that he could make good on his promise in 100 days. If he lost, he would carry the cost of the project.
Well guess what? -big grin- South Australia has a $50 million dollar bill to pay!
More importantly, all the dinosaurs in our government advocating for dirty coal power stations have been silenced, at least for a while.

Today really has been a good day. Thank you, Elon Musk. 🙂
Just in case you haven’t heard/seen the news on the internet, a basic exploit has been discovered in the Wifi architecture, and that exploit has been hacked. That means potentially everything that uses wifi to communicate is vulnerable.
And that includes:
- computers via their router
- Amazon’s Alexa [I think]
- and even cars
Apparently Windows based computers should already be updated against this exploit, although how Microsoft managed to find out so quickly is a worry. However, that is only the computer operating system itself. The router also handles things like internet banking and I have no idea how secure that is now.
Android and Linux are both vulnerable. I believe Apple is too.
As most people these days have wifi routers [the box with the flickering lights that sits between your computer and the internet], I would strongly recommend checking with your ISP* about when you can expect a security update for the router. ISPs are your service providers – e.g. Telstra, Optus etc. Until you get one, I would keep internet transactions dealing with money to an absolute minimum.
Actually, you might consider going around with wads of cash for a while. No seriously.
Oh, and don’t use the free wifi in your local shopping centre because such locales are plenty big enough to make them worthwhile for hacking.**
If any of my techie friends has info to share I’d really appreciate it.
* When you sign up with an ISP, they usually provide you with a router [for a fee] so the ISP should provide info. on updating the router.
** Although this hack is universal, it is constrained by the hacker’s need to be physically within reach of the wifi he/she wants to hack. So home wifi is not that ‘worthwhile’, but a large shopping centre probably would be.
I don’t usually wear sunglasses, but I’d definitely wear these:
The frames are standard, but the lenses collect solar energy which is transferred to the electronic gadgetry hidden in the arms. That gadgetry could be enough to power small wearables such as hearing aids. For me though, the most exciting part is this:
‘Organic solar cells were chosen instead of more traditional silicon cells because they’re transparent, flexible, lightweight, and can be manufactured in a variety of shapes and colors. Each solar cell lens weighs about six grams, is 1.6 mm thick, and was made to fit into a set of commercially-produced sunglass frames.’
The blue highlights are mine, and they’re exciting because the same cells could also, in time, be used on windows. Imagine how much energy could be harvested if windows became solar panels as well as roofs? And think of all those huge skyscrapers – perfect realestate for solar farms. 🙂
