ROBOT.LK

hey guys, i found this website through on of my friends, and he told me to ask from your'll

im doing a project for an exhibition about the above topic heading, i need to know the things i need,and the circuit diagrams, equipment and specially i need to know "IS IT POSSIBLE TO MAKE THOSE"

P.S: if i need projectors for the hologram projector i can afford them too no matter how much its cost our school donates for the exhibition. BTW i have only one months for this project (sepember 26,27,28 are the last days)
thank you
Rasanja

I guess Shenal and Praveen brought you here
Anyway you came to the right place. This is a forum completely dedicated for your type of guys. Warmly welcome to ROBOT.LK!

Both Heat seek and Night Vision are related to IR detection. We can help you to build an IR detector.

Heat seeking

I have a good idea on a project which you can build within the stipulated time.

1. You find two toy cars. One should essentially has remote control.
2. The remote control car has a heat generation device at the back to simulate engine heat. Extra care need to be given to preserve battery power from draining through the coils. You can use a temperature sensor here so when enough heat is not there you can start heating.
3. The other car need to be modified with robotics so it can move, turn, break (not essential) automatically using a microcontroller.
4. Then you need to fix IR detector(s) on a movable arm which can scan a considerable range in front for high heats such as car engine.
5. Once that finds a fix, it need to follow that immediately and you can drive the RC car around. This is the real scenario of a heat seek missile.
6. To start with, you can build the car with IR detector to follow any heat source stationed somewhere in the range. If time permits you can build the heat coil with temp sensor.

If you like, we can discuss further.

Hologram Projector

Here are some starting points.

no, not like a heat seeking missile, it should be a spectacular or a motorbike helmet, if i wear it i should see hot stuff in red, and cool stuff in blue others are in green, thats how we planed to do it,
about the hologram projector thats what im talking about

You can of cause detect the hot areas an cool areas using an IR detector. Visualising it on a display based on the heat values are something up to you. I guess you will have to spend most of your time on R&D on the display part. See Flexible OLED. Since the Hologram method is still at R&D stage, I think it is not suitable for this project which will be held in a month. However it could be a good life time project which you will end up with several new innovations.

its ok, we were hoping to it

how much is a Flexible OLED?? if its lower than 10,000 i can afford it and also i need circuit diagrams too and thanks for helping me

No idea on the price. I have never used this before. We have used OLED displays but not the flexible version. However there is no technical difference in the interfacing. You might start with something like this. http://cgi.ebay.com/128X64-OLED-LCD-LED ... 0338453668. Later you can easily migrate to the flexible version on the helmet.

I do not have time to prepare circuit diagrams. You will have to download the datasheets and start from scratch. Almost every datasheet has a sample circuit diagram page. Besides working on a supplied circuit diagram has no R&D value and no enthusiastic fun as well

Okay. Let me give you some guidance. First decide on what you are making. Then identify the components. Finally put them all together in a PCB design software to make your custom circuit diagram. Otherwise there is no starting point for you. Once you prepare the circuit diagram, we can have a look together. Do not expect us to check every resistor or cap on board . We will check the interfaces from chips to peripherals.

Just don't get things complicated. Unlike learning theory, doing it practically takes unexpected time (since you will have to face several unexpected problems while developing.. Any project have these).

ok, our prefects only trying to do this project, so on their second thought they have planned to build a "night vision goggle" they are giving all the support for me

i know that your busy with your work and you dont have time to design a diagram so if you can tell a person who can do it for us it would be awesome maybe we are planing to bring a instructor, so he may help us with soldering the circuit

also i need to know "what is night vision" because i can explain about it and i need a "part list" which i need to build it

That will be a good project.

Rasanja, the main point is, there is no ready-made diagram or circuit for this. Someone should start from scratch. Need to start form doing a literature survey on present technologies, availability of components, etc... If I find a person who can involve with this, I'll let you know. For now, all guys I know are very busy with their jobs.

also i need to know "what is night vision" because i can explain about it and i need a "part list" which i need to build it

Again the same answer. To give a part list, one should do above mention activities. Literature survey, availability of components, etc...

However I'll try to give you a little introduction about night vision and some existing projects.

This site has lots of information. Read "IR illumination" in detail. I guess this is what going to suit you the most.

You will mostly need following items.
Set of high intensity Infra-Red (IR) LEDs
Small Camera
Microcontroller development board (If you can build a custom board then that's fine. But if it is hard for you, then just for a development board)
About 3" LCD screen

can i know if i couldnt make this project within a month is it easy to make the the other one with the OLED SCREEN??? i could find a elecronic instructor for that i wanna know is he should be an IC PROGRAMMER or a DIAGRAM DESIGNER

also i need to know how should i explain him about the project in geeky way i cant just say him, im doing a project its a night vision goggle i need a circuit blah blah right! thats why.....

and it would be more easier if you can send me the part list which i need to make the diagram

can i know if i couldnt make this project within a month is it easy to make the the other one with the OLED SCREEN???

It's all depending on how dedicated & talented you are in electronics/embedded. Say a talented guy can make something within a week. It might take ages for an average person to do the same thing. Experience also matters in similar projects. For example, if you have handled microcontrollers in your life, it is easy for you do design something with them. If you haven't done such Research & Development based work ever in your life, it will take ages for you to work it out. However it is worth since you can work out the next project faster with that expereince.

i could find a elecronic instructor for that i wanna know is he should be an IC PROGRAMMER or a DIAGRAM DESIGNER

That of cause need to be decided by you. If you are going to put electronics which needs firmware programming, yes, you need to find a person with firmware programming capabilities. If you want that person to design the circuit for you, so he should be able to do that as well. If you are going to use non-programmable electronics then you don't need a firmware programmer. You just need a circuit designer.

An electronics/embedded engineer can do both without any problem. Also, there are some talented technicians who are capable of doing those as well.

also i need to know how should i explain him about the project in geeky way i cant just say him, im doing a project its a night vision goggle i need a circuit blah blah right! thats why.....

I understand. But I'm in a doubt on your contribution to the project. Are you an electronic/technology enthusiast? I felt that you are just trying to get the job done by someone else and get marks under your name? I'm sorry this is not going to work with us. We only support technology enthusiasts.

As said before we have no time to waste. But we help technology enthusiasts by giving them guidance on projects decided by them. For example, if someone needs to drive a motor, we can give him guidance on how to do that.

and it would be more easier if you can send me the part list which i need to make the diagram

My friend, you can understand what I'm telling you. There are many ways to design a circuit. If you take two electronic engineers, they might design the circuits completely in a different way. One might like microcontrollers whereas the other likes Digital Signal Processors. Though the final outcome is same, the circuits can be completely different. Besides, how to predict a list of parts on a project which you haven't even decided yet.

If you don't know what you are making and you need someone else to work it out for you, we can't help you any further. If myself for example do all the designing, etc... then I'll put that item under my name. Not yours .
I'm sure you understand what I'm saying.

There are millions of project ideas in the world and no one has time to discuss everything. So Rasanja, first thing is decide on the project. Then we can discuss with an aim.
