alfaaqua Posted April 22, 2010 Share Posted April 22, 2010 Ive seen alot "anti mosquito" programs which emit sounds that we humans cannot here but the mosquitos can because it is a higher frecuency. Do they actually work? If so, can you recommend a free Java based one? Thanks. Link to comment Share on other sites More sharing options...

This is similar to the device that was implanted to keep young teens away from malls. Link to comment Share on other sites More sharing options...
bluewind. Posted April 22, 2010 Share Posted April 22, 2010 Let me get this straight. You want to keep mosquitoes away ...... ... from your computer? nvm Link to comment Share on other sites More sharing options...
MR_Candyman Posted April 22, 2010 Share Posted April 22, 2010 *sigh* People just don't get it. What it does is emit a high frequency noise from the speakers to annoy them so much they don't come near you. They do work, HOWEVER: The speaker in your phone, and those you would use on your computer can not actually move quickly enough to emit this frequency. There are dedicated mosquito repellant keychain devices that can emit this frequency, and they will work fairly well, but not 100% by any means. Honestly, I find a repellant high in DEET to work far better than them, but a combination is still best yet shockz and alfaaqua 2 Share Link to comment Share on other sites More sharing options...

If it works, great. If it doesnt, oh well. Link to comment Share on other sites More sharing options...

boogerjones Posted April 22, 2010 Share Posted April 22, 2010 *sigh* People just don't get it. Well I don't feel like we should feel inadequate for not "getting it" when some guy asks for a software-based mosquito-repellent. Link to comment Share on other sites More sharing options...

Slammers Posted April 22, 2010 Share Posted April 22, 2010 this thread makes me laugh. I doubt your computer speakers can make the required fequency either. Also not that you probably care but don't ya think a constant sound emmitting from your phone would be hell on your battery life? Link to comment Share on other sites More sharing options...
alfaaqua Posted April 24, 2010 Author Share Posted April 24, 2010 home made mozy repeller: Pretty good :) Anywhere I can find more information? this thread makes me laugh. I doubt your computer speakers can make the required fequency either. Also not that you probably care but don't ya think a constant sound emmitting from your phone would be hell on your battery life? Thought I replied to this.... My speakers are 7.1 so I imagine that they are not your standard mom and pop speakers and can actually reproduce high frecuencies. My phone is plugged in all night so it would not affect battery life. Link to comment Share on other sites More sharing options...
Nadja Posted April 25, 2010 Share Posted April 25, 2010 Anywhere I can find more information? check out your local electronics hobbyist store for mosquito/insect repeller kits, usually quite cheap. for a PC you can get the 12V dc through a molex plug. you need a proper Piezo buzzer/tweeter that can reach to 50khz to be effective, ordinary tweeters in speaker systems peak out at ~20-30khz. have fun :cool: Link to comment Share on other sites More sharing options...

How about the PCB? Where could I get something like that? Will any PCB do and just connect them with wires? Using sound to repel mosquitoes is so 90's...

MR_Candyman Posted April 30, 2010 Share Posted April 30, 2010 ya, if you can't solder, just get a breadboard And NO, your 7.1 speakers WILL NOT WORK. As stated, they can not reach a high enough frequency Link to comment Share on other sites More sharing options...
pyehac Posted April 30, 2010 Share Posted April 30, 2010 Its for my phone. This is similar to the device that was implanted to keep young teens away from malls. which actually kind of backfired. I remembered getting that 'ringtone' and showing it to my classmates in college - the old people couldn't hear it, while the young people could - making it perfect as an alternative to silent or vibrate to let people know they had a call.

As stated, they can not reach a high enough frequency That actually looks great :) What would you recommend that or a stripboard for this? And its too bad there isnt anything small than a PC PSU (AFAIK) to provide 12V to make this a bit more portable :( Thanks alot to everyone that is trying to at least help :) I believe this has NOTHING to do with it as I imagine it is refering to clock frequency but........... Due to large stray capacitance (from 2-25pF per contact point), high inductance of some connections and a relatively high and not very reproducible contact resistance, solderless breadboards are limited to operate at relatively low frequencies, usually less than 10 MHz, depending on the nature of the circuit. The relative high contact resistance can already be a problem for DC and very low frequency circuits. Solderless breadboards are further limited by their voltage and current ratings.

djnv2010 Posted April 30, 2010 Share Posted April 30, 2010 hey how about you stop sleeping outdoors and get an apartment/room somewhere? i don't get it!! why do you need to get mosquitos away? are you around them all day? Link to comment Share on other sites More sharing options...

This is actually the first I've heard about those problems with breadboards. I've made countless projects on them before transferring them to either a stripboard or proper pcb and never had an issue. Why not get a cheap 120v ac to 12v dc wall plugin and power it off that?

Dick Montage Posted April 30, 2010 Share Posted April 30, 2010 I personally think they don't... I downloaded an app called Dog Whistle - it produces high-pitched tones that are meant to alert dogs. No dog I have tried it on even reacts. I just don't think the speakers are up to reproducing the tones needed. Link to comment Share on other sites More sharing options...
