hi i am johnhow , just signed up here in oz i am looking for some one to design a minature board to control a separate 5mw 650nm laser [pointer ] via wifi as wires will interfere with the action of what i am trying to achieve, the laser will be approx 70 -100 mm away [3-4inches] from board, i would like a 9v housing included in the housing , i do not have a lot of room on my project. The laser will be activated via a infrared sensor which an object going past a sensor will activate wifi to enact laser , but as the object will comeback over sensor, i need laser to remain on for 10 seconds, so i dont need it to be turned off until the 10 secs my computer skills just survive , so after joining this group i am intimidated already after reading all the guidelines with schematics, parts etc i have abosulutley no idea on what i am doing and it would take me a lifetime to get to any bodies level on here .I am a pensioner here in australia who has come up with an idea to help adults children with mobility issues to use my idea to aide their developement, i would love any input into creating a design that would accomplish my plans thank you to the electronics world

Your post may be more appropriate in the Gigs and Collaborations section of the forum but note that payment may be expected to do what you want
If you want it moved then please use the Report to moderator link and ask for it to be moved
The alternative is for you to try at least the programming aspects of the project and to get help here. What hardware do you intend to use ?
Is this your first project? If so, it seems too ambitious.
What else is to be in that box?
What is the laser supposed to do?
What is the actual voltage you need? (9V screams regulator, and that can often be avoided).
Battery powered or mains powered?
Do you have a working prototype already?
So many questions before one can even evaluate what you're trying to do...
Not a good description at all! What does "9v housing included in the housing" mean? I have a nasty suspicion that you imagine this can be powered by batteries.
Basically, how about telling us the actual purpose of this device?
Yeah, that would probably be the recessed internal battery holder with cover, that is found on active circuitry electric guitars for example...
*control a separate 5mw 650nm laser
The laser will be activated via a infrared [ motion sensing ] sensor
I need laser to remain on for 10 seconds,
I came up with an idea to help adults children with mobility issues
lots of information missing.
#1) how far apart is the sensor and the laser ?
#2) power consumption for the laser is based on run-time. when tripped, how long before the 10 second time-out ?
#2a) wifi is power hunger, you would be better with a simple low power wireless, RF or LoRa
some details of what you are doing.
The sensor and timing and turning on/off the laser are not feats of great experience. You could get this going in day or weeks and most
Hi,
Welcome to the forum.
Thanks for reading the guidelines, (karma added)

Sorry John but had to spread it out a little, will encourage more readers.
Tom.. fellow Aussie.

Thanks Tom, I got halfway through and gave up. 
A range of a few inches surely can be done with other than Wi-Fi? IR would probably be a good choice here. It's just the rest of the project that we need to understand now!

laser justs sits on a acrylic frame and points straight ahead as the board and battery holder combined in some way sits below ,out of the way on a flat surface approx 70- 100 mm [3-4"] away under the laser a round rod goes thru a set of rollers, which via a i think a ir sensor will turn on laser with a timer for a time [10-15 secs] via wifi , i only have 55mm [2.1/4] width to play with ,maybe 60mm x 90- to 100 mm 2.1/2 x 4" area cost is also a consideration as if price is too high i may go down another path thank you for input

Sorry John, spacing your posts sentences out makes them easier to read.
You may be better to draw some diagrams to explain your project.
From what I gather you need;
- Detect a movement past an IR sensor.
- This will turn a laser on for 10Seconds.
- The link from the sensor needs to be wireless, such as WiFi.
How close are the sensor unit and the laser unit?
There may be a simpler and easier wireless method rather than having to connect to a WiFi network.
I assume the IR sensor will be detecting some part of the human anatomy that the disabled child will be able to move.
What is the purpose of the laser, is it to attract attention or some part of a process/game?
Tom... 
thank you for making it grammatically right, as i have mentioned somewhere here that i am a 2year self taught computer learner with limited knowledge , and i know i am in this electronics forum i am being frowned at , so as i cannot learn anything in a short period of time , i would like you for your time and i will try elsewhere to get the designs
John,
the questions we ask are required to be known by anyone trying to make circuits.
there is no way we can make something work if we do not know how it works and how you want it to work.
anywhere you go, you will find the same questions.
we cannot help if we do not understand the details.
Learning takes time, there is no way for you to complete a project like this (especially as it involves wireless communication) in a matter of days without a lot of prior experience.
Besides, unless you can clearly describe the details of the project (including things like physical size, distances, range of motion) there is no way we can offer suggestions. Without knowing those details there's of course also no way for you to even start making it... as you need to know it to know what you're actually trying to make!
... without being mean, there is a larger key on the RH side of your keyboard that breaks lines (marked RETURN or ENTER). It automatically makes more readable paragraphs.
Catch a breath, and. pretend you’re someone that has no idea what you’re planning.
Draw a sketch, post that, and explain what it’s meant to do.
Then we can suggest strategies.
You may be spot-on, but from the way you’ve mumbled, we have no idea.
Where are you in Oz? There may be an experienced user nearby that could point you in the right direction.

Well, use the search engines by all means but just do not try asking questions on any other discussion forum, because this one probably has the most skilled people of any in regard to whatever project it is that you are attempting and repeating the same performance on another forum will most certainly be no more productive. 
I might add that while this is an Arduino forum, the helpers are not limited to hobby or Arduino experience, and in many cases you’ll be provided with experience from many years, brands and skill sets.
