Timing tolerance:
I received a question about 500 microseconds of lighting and resting of the device, How accurate they need to be?
or 2000 microseconds per cycle?
My response: It's about, plus and minus dozens.
Until the community develop a protocol to measure the effectiveness  we can't say for sure. However we have in house version to help us but only through OBSERVATIONS
The questions on its effectiveness are somewhat vague. They all repel mosquitoes it's not that 1 frequency repels more, and the others less. If there is a difference in real life we are not aware off. Again, it's more important to use multiple units, Please at least 8' distance from the subject to the installed units at the site.

Happy Mosquito Free!

Much too cold for the bugs here now so not able to test anything until late spring.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

We like to see you success on the first trial. The following is an illustration of the minimum settings. Please have 2 or more.

Happy Mosquito Free.

Dear community.


Finally, after a lengthy process of examination the work was reviewed and published by a Peer Review Journal.


Journal: International Journal of Entomology Research.

Wow! Karma+ Phi!
You paper is open access!


I was just asking to you which mosquitoes you were using but finally I found it, aedes aegypti. I didn't find before because of the first letter of aedes that should be uppercase, Aedes, that I searched for. Very strange that this was not corrected in a entomology journal.

For years We tested with mosquitoes emerged from wild caught larvae --- All kind--- It worked---Nature has means to control the populations, the old eating the eggs and the young  therefore we have problem to have large samples for demonstrations. The species in the paper happens to be available for laboratories to purchase.

Roaches in the house.
Our experience:

Our Kitchen is next to a large sunroom/greenhouse with 2 green house doors and the door between the kitchen and the sunroom is nearly never close.

In our kitchen we use ultrasonic device to repel roaches, they are only effective on small ones but cockroaches.

- 1 device at a high corner of  the kitchen works but there are some come from the sunroom. Once they come they don't go out but die, belly up  in a few days. Though the population is greatly reduced. It takes sometimes and detective works to locate the route they use to come to the kitchen.

- We then put up 2 more up high at the 2 ends of the sunroom. Then . . . . no more.

If you ever wonder if you can use PADAUK's MCU. The PMS150C cost around $.0.025 or 2 .5 cents / piece

Here is the sketch:


Code: [Select]

/*
   For Padauk PMS150C-SO8
   Pin are set for SO8
    RED   =  pin #2
GREEN =  pin #3
BLUE  =  pin #7
VDD   =  pin #1
GRND  =  pin #8
 The chip set up by IDE use 8MHz;
 with PA5 is set for open and drain, default is INPUT.

}

{

             // For those who want the accuracy then the total overall overhead timing for this procedure is  = 8 + _ticks2/256 ticks about 3 us addedd.

Tested with the RGB & 5V pins directly connected to a 30 LED USB RGB strip.
Only USB as 5V power supply for VDD & GRND + LED USB RGB strip required, no other component such as resistor, capacitor, etc.  . . . . needed.

Experiences: Drawbacks?.

During the course of deployment there was a drawback on the use of the light.

Mosquitoes use other senses to get into residential areas, while the light has little effectiveness to chase them away or preventing them snicking in  through the door. Example: the room was treated, once they get to the opening of the door they already "see" the area underneath the table in the room as the safe places, they go there. The light need to prevent them to go near to the door in the first place.  If the were in the room they will bite when one gets close, or jump from one 'shadow' to the next to get to the targets.

However here comes the rescue, the trap (page 1 of the topic) As individuals, their cost is the main reason preventing us to deploy them for humanitarian purposes although people were so much loving them, some were able to catch 20 a day.

For the benefit of the community I share my story. I may help.  (I hope the moderator let it passing by, you can delete this)
  • I have had 2 heart attacks, quadruple by-passes, 5 stents + diabetes.
  • For some reasons since childhood I  am unable to play sports, I always failed stress tests, doing so my blood pressure going down instead of  normally up.
  • About a years ago I experienced a lot forgetfulness (early stage of Alzheimer?). I hoped it would not go too bad to interfere the study courses of my children, they are college students.
  • In the big family we have 4 MDs and my wife is a nurse, I had no choice but to act against all their advices before things become too late.

Solution:
For the last 10 months I supplement myself with Oxygen from 'Oxygen concentrator' set at 3L/m, 99% and only at night.
Results:
  • In about a week the forgetfulness gone. Then now after 10 faithful months.
  • Without any change of life style such as diet program or exercise .  . .
  • I lost 35 pounds weight from 150 to 115, and 5 inches of my pant' waist, from 34 to 29.
  • My blood pressure comes from 150+ to around high 120 or low 130.
  • My Cholesterol level downs from around 250 (with medication) to 120+
  • My Sugar level is inconclusive but I don't' use med anymore.
  • My niece is an MD: "We have only 3 things to measure you: Blood pressure, Cholesterol and sugar level you have them in good shape . . . . ."
  • My wife changed from against it  to having one for herself, not because of medical benefits but the disappearance of the wrinkles at the end of the eyes.
  • NOW, Go to Walmart, Home Depot . . .  I don't use motorized shopping cart

Now you have idea why I am not interest in marketing the 'products', (a) I don't have that skill, (b) I don't like, (c) I have important things to finish I hope.....
