Survey of Alternative Displays

Posted on by

[Blair Nearl] has been working on an information database for artists and hackers – a collection of non-conventional display technologies available to us. We’ve covered this repository before, six years ago – since then, it’s moved to a more suitable platform, almost doubled in size, and currently covers over 40+ display technology types and related tricks. This database is something you should check out even if you’re not looking for a new way to display things right now, however, for its sheer educational and entertainment value alone.

If you’re ever wondered about the current state of technology when it comes to flexible or transparent displays, or looked for good examples of volumetric projection done in a variety of ways, this is the place to go. It also talks about interesting experimental technologies, like drone displays, plasma combustion or scanning fiber optics. Overall, if you’re looking to spend about half an hour learning about all the ways there are to visualize something, this database is worth a read. And, if there’s a display technology the author might’ve missed and you know something about, contributions are welcome!

Someone setting out to compile information about an extensive topic is always appreciated, and helps many hackers on their path. We’ve seen that done with 3D printer resin settings and SMD part codes, to name just a few. What’s your favourite hacker-maintained database?

Things like Transparent displays, volumetric displays, modified polarizers, e-ink, flexible displays, lasers and projectors, lightfield displays, head mounted displays, projection on water or fog, diffusion and distortion, switchable glass, drone displays, electrochromic paint, acoustic levitation display, plasma combustion and many more

Some of Canon’s wireless Pixma printers are stuck in reboot loops

Posted on by

Over the last day or two, there have been a growing number of reports by people who own certain Canon Pixma printers that the devices either won’t turn on at all or, once turned on, get stuck in a reboot loop, cycling on and off as long as they’re plugged in. Verge reader Jamie pointed us to posts on Reddit about the problem and Canon’s own support forum, citing problems with models including the MX490, MX492, MB2010, and MG7520.

Some believe their problem is due to a software update Canon pushed to the printers, but that hasn’t been confirmed yet. In response to an inquiry from The Verge, corporate communications senior director and general manager Christine Sedlacek said, “We are currently investigating this issue and hope to bring resolution shortly as customer satisfaction is our highest priority.”

Until there is an official update or fix, some people in the forums have found that disconnecting the printers from the internet is enough to keep them from rebooting, with control still possible via USB.

To get the printers to work while maintaining your connection to the internet and their connection to local network devices, one reply from a customer on Canon’s support forum suggests a method that many people report has worked for them. If you’re experienced with network setups, DNS servers, and IP addresses, it could be worth trying, but for most people, I’d recommend waiting for an official solution.

To follow their steps, then, after taking your internet offline, turn on the printer, go into its network settings, and, under web service setup, select DNS server setup and choose manual setup. In that section, input an internal network address (192.168.X.X, with numbers replacing X that aren’t in use by any other devices on your local network), press “OK,” and then press “no” for a secondary DNS server. This keeps the printer connected to your router without accessing the wider internet, and, for some reason, has been enough to stop the devices from rebooting.
