Hackaday Links: March 31, 2014

Wanting to display his Google calendars [Chris Champion] decided to mount an old monitor on the wall. The hack is his installation method which recesses both the bracket and the outlet while still following electrical code (we think).

Since we’re already on the topic. Here’s a hack-tacular project which hangs a laptop LCD as if it were a picture frame. We do really enjoy seeing the wire, which connects to the top corners and hangs from a single hook a few inches above the screen bezel. There’s something very “whatever works” about it that pleases us.

[Jaspreet] build a datalogger in an FPGA. He put together a short video demo of the project but you can find a bit more info from his repo. He’s using a DE0-Nano board which is a relatively low-cost dev board from Terasic.

Want to see what’s under the hood in the processor running a Nintendo 3DS? Who wouldn’t? [Markus] didn’t just post the die images taken through his microscope. He documented the entire disassembly and decapping process. Maybe we should have given this one its own feature?

If you’re streaming on your Ouya you definitely want a clean WiFi signal. [Michael Thompson] managed to improve his reception by adding an external antenna.

We always like to hear about the free exchange of information, especially when it comes to high-quality educational material. [Capt Todd Branchflower] teaches at the United States Air Force Academy. He wrote in to say that his ECE383 Embedded Systems II class is now available online. All the info can also be found at his Github repo.

And finally, do you remember all the noise that was made about 3D printed guns a while back? Well [Mikeasaurus] put together the .iStab. It’s a 3D printed iPhone case with an integrated folding blade…. for personal protection? Who knows. We think it should be a multitasking solution that functions as a fold-down antenna.

  1. The only part of Champion’s build that may be questionable is how he mounted that receptacle box. Plus, he now has a huge hole in his wall that he’ll eventually have to cover up.

  2. “Want to see what’s under the hood in the processor running a Nintendo 3DS? Who wouldn’t? [Markus] didn’t just post the die images taken through his microscope. He documented the entire disassembly and decapping process. Maybe we should have given this one its own feature?”

    Probably, but at least there’ll probably be more on the way you can post about.

  3. Neat…now when people point out how tiny your iPhone screen is, you can just stab them! Maybe the next version could have a crummy rimfire pistol thing built in…or maybe just 3D print picatinny rail mounts for your phone and mount it to the top of an AR-15.

    1. Doubtful the wall is a fire wall as there is no insulation. For typical residential, the only wall that would be a fire wall is between the house and an attached garage, but again, there would be insulation and a vapor barrier present. (If it was a mulit unit dwelling unit or townhome, adjoining unit walls would be double sheetrocked.)The hole in the wall would be no different than a return air duct on a typical house, which is simply a hole cut into the sheetrock to allow the air to pass through the stud cavity. The only lining is the wood stud, and typically it’s not even a fire treated wood that is used (may vary by jurisdiction).
