  • The idea of using WIFI to trigger explosives makes me very nervous. I’ve been working with WIFI (as in RF design and embedding in computing products) since the late 90’s and want to emphasize that the average hacker/maker should NOT buy an off-the-shelf WIFI board and just put it into a pyrotechnic controller.

    For this kind of application, there should be modifications to improve the datalink’s reliability and immunity to accidental and deliberate interference, as well as protocols to guarantee that only authorized members of the subnet have access. Fail-safe high reliability coding should be used to guarantee that in case of error the system shuts down and disconnects from power.

    The electrical and physical construction should continue this theme with hardware interlocks and the ability to remotely mechanically disconnect from power. As the article says, do your research. Even better, apprentice yourself to someone who has done this professionally for years.

    That said, cool article. I wish I lived in a state that allowed this kind of stuff.

  • Yes. That’s it, exactly :-)

  • How do you like to write Python? Totally sloshed

    What IDE(s) do you recommend, even if it means installing it separately on something like a Raspberry Pi? sed. Hey, when you’re totally sloshed, sed’s as good as anything out there. And I made a deal with it - since sed doesn’t have a debugger, I won’t write any bugs.

  • Ooh! My very own $1.4 billion per watt radioactive battery!

    Come on, April Fool’s was two months ago.

  • Is there somewhere we could see this in text form, say a transcript file?

  • Gotta love the idea of a claw hammer for the home office. Lots of uses - back scratcher, bad dog pacifier, insect control, jar opener, wall-climbing tool, phone conversation emphasis point generator, emergency window opener (in case of fire), back-up TV remote control, light switch… The list goes on almost forever.


  • I hadn’t planned on it, it didn’t seem like something others would want, but if you think there’d be demand for it, sure. Guess I need to look into how to do that.

  • Yep, good eye.It’s part of my modular Pi case system. There’s also a snap-on lid and a snap-on base. The base is common to all versions of the case, while the lid has different features to accommodate different configurations (various displays, switches, even a ZIF socket for a chip burner). There’s also a version of the case that has a gap on the top right side to allow a ribbon cable to pass through to the GPIO header.

  • Just to join the line of “Hey, you didn’t show the CAD program I use”, here’s an example of a print I put together with FreeCAD. Free, open source, a bit quirky but it works.
