“vladimir_1982” on is selling our open source cell phone jammer plans. It’s open source, commercial use allowed, attribution, share-alike… so it’s actually ok for him to do this, it’s just lame. So here’s a post about it, hopefully no one pays US $24.95 for a PDF of our site.

You will receive the Designs (Plans) for this RF Jammer in Electronic form. The Listing picture is for showing how the RF jammer looks like. This listing is only for the Design of the RF Jammer, it does not include the Device itself!!! You will receive RF Jammer Designs upon Payment. The Designs will be delivered to you on CD by Priority Mail.


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @

  1. man that sucks, is there a way to burst their bubble and post links to the free documentation

  2. “100% positive feedback” Ha! This is lameeeee…

  3. I think you’ve taken the right track, acknowledging that it’s ok, but calling him out.

    Being a bit more cynical, I might think “vladimir 1982” is providing an always-valuable lesson as well … that there can be many prices for a thing.

  4. Attribution… I don’t see an attribution on the listing.

  5. His/her 100% positive feedback is from someone else who’s already bought a set of plans.

  6. Paul, yeah…from someone in the same city 😉

  7. what is really funny is from deals extreme you can get a prebuilt one for 30 bucks, no shipping

  8. There’s almost attribution. If you blow up the picture you can see the Adafruit logo and name on the board inside the cigarette pack. Anyone with any sense would see that and google Adafruit before bidding.

  9. The funniest thing about this is that $24 is a bargain in NYC for a pack of Newports 🙂

  10. Don’t worry – it’s not like anyone would build it.

  11. According to the feedback that the seller has left for others, he sold this twice.
    (one of the buyers another person in Bulgaria??)

  12. ah heh right, bypasses the open source laws by sending over cd and claims as a cover charge.

  13. While the Adafruit Industries logo is visible, I don’t think this person made any conscious effort at attribution whatsoever. Happening to have the logo on the box in this case is just “ripping off adafruit” in my opinion, not attribution.

    As a result, I don’t think they are actually compliant with the attribution clause in the CC license.

  14. Actually, he has to send a CD because ebay won’t allow you to sell anything that is delivered electronically like software or files. (Or WoW accounts.)

  15. Yes, this is lame. Just looking at the wave bubble site, one the reources page, the link “The FCC code section 15 which covers interference” is incorrect.

  16. That reminds me of something I keep forgetting to mail Limor about. I assume she’s aware, but just in case she isn’t (and because presumably other people would be interested too) the wavebubble makes an appearance in Greg Rucka’s novel WALKING DEAD and she’s name-checked in particular.

Sorry, the comment form is closed at this time.
