Hackaday Links: October 14, 2018

Here’s something of interest of 3D printing enthusiasts. How do you print lightweight 3D objects? [Tom Stanton] does a lot of stuff with 3D printing and RC airplanes, so yeah, he’s probably the guy you want to talk to. His solution is Simplify3D, printing two layers for whatever nozzle diameter you have, some skills with Fusion360, and some interesting design features that include integrated ribs.

Moog released their first polyphonic analog synth in 35 years. It’s massive, and it costs eight thousand dollars.

There’s a RISC-V contest, sponsored by Google, Antmicro, and Microchip. The goal is to encourage designers to create innovative FPGA and soft CPU implementations with the RISC-V ISA. There are four categories, the smallest implementation for SpartFusion2 or IGLOO2 boards, and the smallest implementation that fits on an iCE40 UltraPlus board. The two additional categories are the highest performance implementation for these boards. The prize is $6k.

” I heard about polarization filters and now I’m getting a hundred thousand dollars” — some moron. IRL Glasses are glasses that block screens. When you wear them, you can’t watch TV. This is great, as now all advertising is on TVs for some inexplicable reason, and gives these people an excuse to use frames from John Carpenter’s masterpiece They Live in their Kickstarter campaign. Question time: why don’t all polarized sunglasses do this. Because there’s a difference between linear and circular polarized lenses. Question: there have been linear polarized sunglasses sitting in the trash since the release of James Cameron’s Avatar. Why now? No idea.

Alexa is on the ESP32. Espressif released their Alexa SDK that supports conversations, music and audio serivces (Alexa, play Despacito), and alarms. The supported hardware is physically quite large, but it can be extended to other ESP32-based platforms that have SPI RAM.

    1. Just get any pair of real 3D, true 3D or any passive 3D cinema glasses and rotate the lenses by zero or 90 degrees (depending on the lens) and see for yourself. I would not call it block, just strongly attenuate.

  1. >Moog released their first polyphonic analog synth in 35 years. It’s massive, and it costs eight thousand dollars.

    and it will be very popular despite sounding the same as ipad app, its all in the appearance

    1. *and the experience.

      It’s way, way, way more intuitive to use a mechanically moving, physical keyboard than it is a glowing piece of glass. Also, glowey glass doesn’t generally have pressure sensitivity, force feedback, etc. (yes, I know that iPhones have it, but I highly doubt that GarageBand, or any other app actually uses it well.) Also, I don’t see a bajillion outputs on an iPad, and it’s much more reliable to have physical wires out of a keyboard than it is to use Bluetooth, especially in a concert setting.

      an iPad is NOT a replacement for a physical keyboard.

      You also can’t patch your own circuits into an iPad, which is something that a lot of musicians really like to do with synths and the like.

      1. which is why (IMHO) cars are able to move to touchscreens and lose that tactile ability to find the button and having to actually take eyes off road to look at the screen because the driving aids mean the radar will stop you hitting the car in front or auto steer you around the bend.

        Technology bringing progess!

  2. RealD3D uses circularly polarized light. If they used linear polarizer filters, shining a LASER through them would produce diffraction patterns. It doesn’t do that. All that happens is a slightly dimmed spot.

  3. Regular polarized glasses will block lcd. You just have to tilt to the proper angle. Like 45* or so. I think lcd screen makers must have planned on being able to watch with sunglasses on.

  4. Wow, it is unbelievable what people will pay $70 for. I’ve never seen a more ridiculous scam. “IRL glasses do not yet block smartphones or digital billboards (OLED). ” AND NEVER WILL as that would require some form of innovation.

    1. they seem to think that they will be able to do so, from their FAQ:

      “We’ve spoken to leading optics engineers at Waymo, Nasa, and Snap to help us figure out how to create an advanced pair of IRL Glasses that block all screens, including OLED and smartphones. With their help, we have developed a few hypotheses about technology solutions for our ultimate pair of IRL Glasses. We hope the success of this campaign expands our community and attracts investors, allowing us to raise the capital needed to pursue R&D and explore our hypotheses.”

      The amusing thing is that for the most part all of the screens that i look at have an off button that I control. I dont see the point in buying sunglasses to block the screen on my own smart-phone when i could just turn it off. as far as screens that i dont control, well good luck to them to try and devise a passive device to do so as i dont see anyone who would put up with the weight associated with an active device (google glass what?)

      “a fool and his money are easily parted”

  5. “Moog finally got off their asses to make a Prologue 16 competitor. It’s massive, and it costs eight thousand dollars.”
    – FIFY
    That being said I want the Korg Prologue 16 more cuase its both analog poly 16 and has a DSP with an open API for FM synthestsis. Or I might just say fuckit and get a DSI Prophet 16.

  6. I have a pair of prescription sunglasses with a polarising filter applied, but the filters are slightly off axis from each other. When looking at an LCD at an angle that blocks most of the light to one eye my other eye will be able to see the image, although attenuated. It’s a very strange experience.
