We all know people trapped in aging bodies who can’t do all the things they used to do. It’s easy to accept that you may never move small furniture around by yourself again, but losing the ability to do something as simple as separating the pages of your newspaper to keep reading it is an end to enjoyment.
When [Randomcitizen4] visited his grandma over the holidays, she mentioned having trouble with this, among other things. He fired up his printer and got to work designing a device to help her get back to the funny pages. This simple gripper mechanism uses rubber bands for tension and flexible filament to get a firm grip on the paper. The jaws default to the open position so they’re ready to grab some newsprint, and a light squeeze of the handles slides the top page back from the stack, creating a gap for Grandma’s fingers. You can see a demo
on page 32 after the break.
Although the device does work on some books and magazines, he’d like to improve the design of the grips to make the device more universally useful. [Randomcitizen4] says he tried a few things already, but we wonder if a more complex surface pattern might do the trick — maybe less like fins and more like a tire tread pattern. All the STLs are available if you want to give it a go.
If Grandma’s newspaper ever goes out of print, she should still be able to read it on a tablet or an e-reader. Then maybe [Randomcitizen4] can build some kind of remote-controlled page turner for her.

It turns out that old newsprint can be a bit explosive; at least when it’s combined with the proper ingredients. [Markus Bindhammer] worked out a way to make solid rocket propellant from newspaper. Judging from the test footage after the break the home made engines work great!
There isn’t a long list of ingredients. In addition to newspaper you’ll need some potassium chlorate (KClO3) which serves as an oxidizer, white wood glue, and PVC pipe. The KClO3 is ground with a mortar and pestle, then run through a sieve before being combined with the wood glue. This combination is painted on the newspaper which is then rolled up with a glass rod at the center. This is allowed to harden before going into the PVC. The excess is trimmed and the whole thing is baked in a convection oven at 105 C for two hours.
If this process doesn’t suit you maybe cooking up a batch of sugar-based propellant is worth a try?

Oh no, lets hope this little gimmick doesn’t catch on. Volkswagen has put out an advertisement in an Indian newspaper that plays an audio file when you unfold the paper. This appears to work much like those greeting cards that play a song when you open them. There’s a sensor that detects the newspaper opening, probably just a piece of plastic or paper that slides out from between two contacts. This allows power to the circuit and the audio file is played. Can you imagine how obnoxious this could be? Especially if your newspaper was riddled with these and those E-paper screens. Then again, that speaker looks like massive overkill for this kind of thing and might be a decent piece electronics to keep in the reuse bin. You can see a video of the newspaper after the break.
