What I want is a tiny portable bluetooth jammer for those who insist everyone in public must be listening to their music. Sadly they are too clunky to haul around each day.
- abirch 2mo agoUnfortunately for me, when I hear music it's from the horrible audio of a cell phone speaker.
- subw00f 2mo agoAre they? You can make one pretty easily and sew it into your backpack for added camouflage. I heard.
- itubaj 2mo agoIf I am not mistaken, this type of jammer can severily affect people with pacemakers. But, as a Brazilian citizen, I can understand the feeling of being forced to listen other's people music.
- yjrpnz440v0b2n1 2mo agoits myth youre mistaken because that would mean all the wifi devices and normal bt devices will also stop pacemaker. only early version of pacemaker before internet would be affected modern pacemakers have protection as long as you keep a safe 6 inch distance
- itake 2mo agocan you cite the source? I'd imagine temporary (15 minutes?) disruption would be considered in the design of pacemakers or blood glucose monitors, but if you're using this in close proximity for a long period of time... then wouldn't there be problems?
- alightsoul 2mo agoIn a third world country which are the most affected by this, Pacemakers are very rare and if you have one chances are you live in a rich area where you don't live with neighbors who do that. People die before they ever get a chance at having a pacemaker and the very conditions that require it are very rare in those areas in the first place
- nom 2mo agojamming on 2.4ghz will in no way impact the core function of a pacemaker yes, the new ones come with BT LE so you can monitor it via your smartphone (yeah really..) but I would not call that 'severely affected'
- yjrpnz440v0b2n1 2mo agohow i even make a clunky one ? need one for a neighbor in 3rd world country with lowest civic sense. i tried that esp32 that uses nRF24 but it doesnt seem to jam all the time. i heard about hackrf one dont know if its can properly do that.
- aidenn0 2mo agoYou can brute-force jam the entire 80MHz range. However, it would require roughly 13dB more power compared to jamming a narrow-band signal. In theory, you could try to exploit the adaptive frequency hopping that bluetooth does, nudging it to switch to specific bands, which you will then jam; this could save on energy, but I don't know if anybody's done it.

- blululu 2mo agoThis guy has an open schematic: https://github.com/cifertech/RF-Clown https://github.com/cifertech/RF-Clown You can use their files to make one via a pcb vendor like jlpcb or you can look for someone who has already done that: https://www.tindie.com/products/ryanyu/rf-clown-v20-esp32-wireless-security-tester-kit/ https://www.tindie.com/products/ryanyu/rf-clown-v20-esp32-wi...
- embedding-shape 2mo agoThese "solutions" always seem too broad with too much collateral damage. Would this be doable to do with a directional antenna or something instead, so you could aim at the specific speaker (in your own house) you want silenced?
- alightsoul 2mo agoYou will need to use your own
- embedding-shape 2mo agoYeah, I didn't expect Bluetooth jamming to be available as SaaS exactly.
- jcarrano 2mo agoIt is called "Reggaeton be Gone"[1]. I think the author had too many problems with his neighbor. [1] https://github.com/ronibandini/reggaetonBeGone https://github.com/ronibandini/reggaetonBeGone
