The operation of transmitters designed to jam or block wireless communications is a violation of the Communications Act of 1934, as amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act prohibits any person from willfully or maliciously interfering with the radio communications of any station licensed or authorized under the Act or operated by the U.S. government. 47 U.S.C. Section 333. The manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited. 47 U.S.C. Section 302a(b). Parties in violation of these provisions may be subject to the penalties set out in 47 U.S.C. Sections 501-510. Fines for a first offense can range as high as $11,000 for each violation or imprisonment for up to one year, and the device used may also be seized and forfeited to the U.S. government.

Hi,

Thanks for a great project. Looking forward to build it.

I was checking out the designs in Eagle and the parts on the website and noticed some differences:

    On the website D2-D4 are mentioned as Schottky diode, but in the design D4 is a zenerdiode (1N5235) which is mentioned nowhere on the web pages.

    LED1 on the Power supply is not mentioned in the design. Also the description mentions a 1206 package, but the link points to a 1208.

    L5 and L6 in Tuning in the design are Neosid inductors pdf, but on the web site they are 1K resistors.


Any specific reason for this? Which is correct?

Thanks
yopper

I believe the L5 and L6 listed on the main board can be resistors of 1k value (1206) and/or you can use inductors (1206) to reduce the noise in the PWM - so one would need to know what the noise of a particular implementation is to be able to compensate for it, hence the apparent ambiguity in the design (most exellent design, by the way). Kudos to ladyada!

fixed

LED1 on the Power supply is not mentioned in the design. Also the description mentions a 1206 package, but the link points to a 1208.


1206 == 1208

also, the LED1 is really used on the battery board. page has been updated.

pdf, but on the web site they are 1K resistors.


see above
