A few days after the tropical Betas passed south Texas, the lawn became "infested" with small leaf eating insects, 5-6 jumped and hopped with every one's step. Some are tiny about 2x of the mosquitoes, other are about 1/2" moth like). At the same time at the treated front yard were virtually none.. And mosquitoes too!
This is the yard (70' x 70' ?) with the location of the device that was placed at 11' (feet) high. It was ON since 5-6 PM yesterday.
And the device: It was vertically installed to have 2 units pointing to the lawn, the upper is not used. (It was designed for ceiling mounted position to cover all around, 360 degrees.)
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.
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.
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:

BLUE = pin #7

GRND = pin #8

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.
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.....
zoomx:
Here it is winter, so no mosquito. I believe that will test it in spring.
Reminder: Small detail but big difference.
RED flashes are essential color to repel insects while Arduino modules come with mostly RED LEDs as power indicator or signals such as D13 . . . Please have them taped, covered or out of the ways. Happy Mosquito Free! Published: Peer Review Journal. Phi
To help your successful implementations of the light I think I should share some observations that I accumulated over the years, I hesitate to list because they are not proven scientific findings. Please take them as their faces only.
The above is the extreme magnifications of a mosquito eye. We can draw some 'conclusions'
You light may appear only to a few lens they have all other safer directions to go thus from more location is better. More lights are better.
With them, a moving object means it jumps from one lenz to the next, they could detect how fast it is.
In order for them to navigate without colliding passive objects, they detect the the distance by a simply shake of their eyes there head, The faster it "jumps" the closer it is.
Our lights just deny them means to such mechanism to calculate the distance . . . . They are right at their front . . . . to run away from.
