Laser Guidance, Maglav Wagon, Wifi barrier

AI Thread Summary
The discussion revolves around a senior project involving three main ideas: a laser-guided missile, a WiFi barrier using focused jammers, and a MagLev wagon. The focus is primarily on developing the missile's guidance system, which utilizes simple programming to interpret sensor data and control the fins. A challenge noted is ensuring the system only responds to the specific laser, with suggestions for modulation techniques to distinguish it from ambient light. Additionally, there are considerations for the physical design of the WiFi barrier and the power requirements for the various components. Overall, the project aims to blend technical innovation with practical applications while adhering to legal guidelines.

Hey all!

I am gearing up for next year to do a senior project, I want to knock it out in my spare time for the next 10 months.

Ideas are:
1) Laser guided missile- 2 phase motor, one to go up then again to go to 'lazed' target.
2) Wifi barrier- setup focused jammers to create a 'wall' of interference
3) MagLav wagon- Mix metals in concrete flooring and setup a wagon with inductors so all the weight is easily moved
 
Engineering news on Phys.org
Alright, well so far I have been working on the guidance for the missile. It has been easy to make a simple program where the sensors in the cone will have a value of 1 or 0 and then summed up for that region. I figured that with the speed at which this thing will be flying, it really does not need to be incredibly smart and simple case statements for comparing the regions will suffice with few exceptions. Once the region has a value, it translate to the motors hooked up to fin, blah blah blah...
My only problem so far is making sure the system only picks up my laser and not all forms of light. My STM32 board and a simple circuit should be able to handle that after trouble shooting. I am now thinking about a good power source for the board and flaps to demo and one for actual flight.

For the demo to profs it won't be flying and only be showing how when the laser moves the flaps move. But ill make sure a video goes up for when I get this puppy all put together.

Has anyone done anything like this before?

Glad you went with #1 and #2. No reason to be doing anything illegal for a school project. :smile:

The simplest way to distinguish your laser spot is to modulate it. You can use a continuous wave (CW) modulation at some frequency that does not have any natural light noise issues, or you could get fancier (like the military) and put a code in the modulation so that the projectile could distinguish which spot is its spot. That would be even a cooler project -- being able to have two projectiles in flight at once, hitting two different targets separated by a few meters.

LOL If i do it right i should get a visit from a few suits... jk jk
This sucks cause I am taking my signals class next semester so ill wait till then to do the modulation but i like the idea that it recognizes the laser via the 'pattern of light' the laser makes. That definitely changes my code though for sensor read out. Gotta love how this missile is getting smarter as i put more time into this project. Lastly, the only problem that I have now is figuring out how to set the flaps on the wings with the motor on account of the size of the missile. I want this thing as small as possible so that the wings do not have as much influence over the flight path. I am looking at these four little wings as softly turning the missile over a distance without sharp turns because the speed amplifies all the errors that could occur.

Oh an the law states that I can "offensively" block wifi =D ... which is why I am sticking to a physical block with signal and not a hack. I am thinking about running the actual antenna along the say a fence with thick aluminum on each side but its open on the top an bot, would look like, | O | so that it creates more of a 'wall' than anything. Than have say, four beacons, each with an amp, setup in a given area...

There should be little to no interference from wifi 2 on 1 and vice versa... only issue is power LOL

Hi there! Your ideas sound very interesting and ambitious for a senior project. Laser-guided missiles have been used in military applications for precision targeting, but it could definitely be a fascinating project to explore the technology and mechanics behind it. Similarly, creating a wifi barrier using focused jammers could have practical applications in blocking unwanted signals or enhancing security measures. And the concept of a MagLav wagon, utilizing magnetic levitation technology, is also quite intriguing. Whichever project you choose, I'm sure it will be a great learning experience and a valuable addition to your scientific knowledge and skills. Good luck with your project!
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
