    Emergency Power Bank

    Might you be able to stay miniature with SMD ceramic capacitors? Pretty sure the datasheet doesn't demand a big juicy electrolytic.

  • Modifying a Cheap Portable Cellphone Jammer

    You are quite right, and as such it is quite surprising that Autodesk (a huge US software company that owns Instructables) hasn't taken severe action against the author of this project for their willful disregard for RF interference law, and potentially for the health and safety of those within range of this illegal device.

    Even a private shop may tip off the Feds, especially if they deal with customers who come in with "broken" phones found to be working just fine, and those customers are clustered in a particular location. A phone shop will work to keep phones running, not help someone illegally shut them down.Keep in mind that Instructables is now owned by a major software company Autodesk, who is a member of the scary copyright group BSA. So certainly they have enough lawyers to know that allowing discussion of illegal activities is not the best idea.

    In such a case talk to your teacher. Even absent any specific rules regarding specific devices, there still should be a general clause regarding disruptive behavior.Stay away from jammers, as these days mobile phone companies are monitoring signal quality all the time for service anomalies, and will investigate anything that doesn't look right. A phone company actually busted a science teacher in Florida about a year and a half ago.

    The person who posted this instructable has a profile that says "Phoenix, AZ." They broke Federal law in three ways:* Importing a RF jammer.* Manufacturing a RF jammer (calibration might count).* Operating a RF jammer (unless this was done completely inside a "Faraday cage" to prevent stray emissions).Here is the official FCC webpage on the illegality of cell and GPS jamming:

    But would that junky plastic just glow blue and block out all the UV?Though many highlighter pigments do tend to be reactive to blue light too.
