Hackaday Belgrade Call For Proposals Now Open!HackadayBelgrade2018V1-01-featuredMike Szczys

Mon, 22 Jan 2018 16:01:32 +0000

Prepare yourself for the return of Hackaday Belgrade! Our premier European conference — Hackaday Belgrade — is on 26 May and we want to hear what you’ve been working on. The Call for Proposals is now open. We seek talks and workshops exploring the most interesting uses of technology and the culture that goes along with it. This includes design, prototyping, research, manufacturing, and the stories of people and progress that move hardware hacking forward.

We’ve booked Dom Omladine for the event because it was perfect for our previous Belgrade conference in 2016. The sold-out conference became a living organism …read more

Quantum Computing Hardware TeardownQuantumbryancockfield

Mon, 22 Jan 2018 15:00:34 +0000

Although quantum computing is still in its infancy, enough progress is being made for it to look a little more promising than other “revolutionary” technologies, like fusion power or flying cars. IBM, Intel, and Google all either operate or are producing double-digit qubit computers right now, and there are plans for even larger quantum computers in the future. With this amount of inertia, our quantum computing revolution seems almost certain.

There’s still a lot of work to be done, though, before all of our encryption is rendered moot by these new devices. Since nothing is easy (or intuitive) at the …read more

How Low Can an ESP8266 Go?aggressively-low-power-with-the-esp8266-i3ljwcrsluamkv-shot0004_featuredwd5gnr1

Mon, 22 Jan 2018 12:00:00 +0000

We’ve been tuned into coin cell designs lately given the coin cell challenge, so we were interested in [CNLohr]’s latest video about pushing the ESP8266 into the lowest-possible battery drain with coin cells. The result is a series of hacks, based on a reverse-engineered library and depends on a modified router, but that gets the power consumption down by more than a factor of ten!

Although the ESP8266 has a deep sleep mode that draws only 20 microamps or so, that isn’t as rosy as it seems. If you could go to sleep for a while, wake up for just …read more

We Couldn’t Afford An Oculus, So We Built Onevrwd5gnr1

Mon, 22 Jan 2018 09:00:00 +0000

Like a lot of 16-year-olds, [Maxime Coutée] wanted an Oculus Rift. Unlike a lot of 16-year-olds, [Maxime] and friends [Gabriel] and [Jonas] built one themselves for about a hundred bucks and posted it on GitHub. We’ll admit that at 16 we weren’t throwing around words like quaternions and antiderivatives, so we were duly impressed.

Before you assume this is just a box to put a phone in like a Google Cardboard, take a look at the bill of materials: an Arduino Due, a 2K LCD screen, a Fresnel lens, and an accelerometer/gyro. The team notes that the screen is what …read more

Someone’s Made The Laptop Clive Sinclair Never Builtspec-laptop-featuredjennylist

Mon, 22 Jan 2018 06:00:00 +0000

The Sinclair ZX Spectrum was one of the big players in the 8-bit home computing scene of the 1980s, and decades later is sports one of the most active of all the retrocomputing communities. There is a thriving demo scene on the platform, there are new games being released, and there is even new Spectrum hardware coming to market.

One of the most interesting pieces of hardware is the ZX Spectrum Next, a Spectrum motherboard with the original hardware and many enhancements implemented on an FPGA. It has an array of modern interfaces, a megabyte of RAM compared to the …read more

Weaving With Light: An OLED Fibre Fabric Displayoled-fibre-montage-featuredjennylist

Mon, 22 Jan 2018 03:00:00 +0000

If you think of wearable electronic projects, in many cases what may come to mind are the use of addressable LEDs, perhaps on strips or on sewable PCBs like the Neopixel and similar products. They make an attractive twinkling fashion show, but there remains a feeling that in many cases once you have seen one project, you have seen them all.

So if you are tiring of static sewable LED projects and would like to look forward to something altogether more exciting, take a look at some bleeding-edge research from a team at KAIST, the Korean Advanced Institute of Science …read more

You know what next week is? Sparklecon! What is it? Everybody hangs out at the 23b Hackerspace in Fullerton, California. Last year, people were transmuting the elements, playing Hammer Jenga, roasting marshmallows over hot resistors, and generally having a really great time. It’s the party for our sort of people, and there are talks on 3D projection mapping and a hebocon. I can’t recommend this one enough.

The STM32F7 is a very, very powerful ARM Cortex-M7 microcontroller with piles of RAM, oodles of Flash, DSP, and tons of I/O. It’s a relatively new part, so are there any breakout …read more
