Laser Trip Wire Security System | Simple DIY Project - Duration: 6:04.
Hi, guys welcome to electrical projects channel, and in today's video, I'll show you how
to build very simple security alarm system that uses lasers.
You've probably have seen such security devices many times in the different movies,
And that is what I am going to build today.
Let's have a look at what we components we need for making such alarm system.
The main component, of course, is a cheap laser pointer.
Also, we'll need two MOSFET transistors 2N7000, an active buzzer, a Light dependent
resistor LDR07, a button for reset, an LED for indication and two resistors, one of which
is 1K Ohms resistor and the second 470 Ohms.
Also we'll need wires.
For the powering, I'll use a 5V power supply.
Let's start making this device.
On the left side, you can see the schematic, as you can see it is really simple.
Well, let's start building.
First, let's disassemble this laser pointer
and let's solder two wires that will power the laser.
Let solder the negative wire to the resistor,
like this…
and the second wire I will connect to the housing of this laser pointer.
Now let's check that this laser still works.
Let's connect the power supply and do a test.
Good sign, the laser survived my soldering which means that we can continue building
our security system.
Ok let's continue, First, I am going to
solder two wires to this button.
Now let's solder a 1k resistor between the gate lead and the source lead of the MOSFET.
Now let's connect the button in parallel to the Light dependent resistor.
Now let's solder the button with the light dependent resistor to the gate lead of the MOSFET.
Now let's connect the negative wire from the laser to the drain lead of the MOSFET,
And let's connect the positive wire from the laser to the button with the light dependent resistor,
Okey,
Now let's connect a black and a red wire that will be connected to power supply later.
We need to connect the black wire to the source lead of the MOSFET.
And the red wire we need to connect to the yellow wire that powers the laser
Now let's do a quick test.
To do a test let's connect what we've built to the power source.
Now when you press the button the laser turns on, and when you release the button the laser
turns off.
Well, nothing special here, but It becomes much more interesting when I point the laser
at the light dependent resistor.
Now when I press the button the laser stays on, it stays on until I block the light.
Pretty cool, isn't it?
As you can see this part of the circuit works well and when I block the light from laser
it triggers our security system, but so far we don't have any buzzer to indicate that.
So let's build the remaining part of the circuit.
First I am going to solder the LED and 470 Ohms resistor sequentially.
Now let's connect the LED and resistor to the buzzer.
Now let's solder the drain lead of the transistor Q2 to the minus lead of the buzzer and to
the cathode lead of the LED.
Ok, now let's solder the plus lead of the buzzer to the positive red wire.
Now let solder the source lead of the transistor Q2 to the negative black wire.
And last what we need to solder is the gate lead of the transistor Q2 to the Drain lead
of the transistor Q1.
Ok, this device is ready to let's test it.
Let's connect everything to the power supply.
and let's plugin.
Ok, now let's press the button and let's point the laser at the light dependent resistor.
Ok, let's see how it works.
As you can see it works.
Pretty cool.
Now, I've pointed the laser at a mirror and the mirror reflects the light from the
laser right at the light dependent resistor.
Let's see how it works this time.
And that is all for today, I hope this video was interesting, is so then like it.
Also, you can subscribe to my channel so you don't miss any of my future videos.
And Thanks for watching!

How to use the Library's Online Catalog - Simple Search Tips - Duration: 5:25.
HOW TO USE THE LIBRARY'S ONLINE CATALOG
SIMPLE SEARCH TIPS
Open the library's website.
www.ek.szte.hu or www.bibl.u-szeged.hu
On our startpage you can search in the catalog,
search in our e-resources,
or browse databases from A to Z.
Let's try a simple search term in the online catalog.
The engine will search in all the fields of our documents' records.
But keep in mind that we only have hungarian subject headings at the moment.
Click the Search button or press Enter.
You can change the language in the top right corner.
You can always clear the results page
and start a new search with the Catalog Home button.
There's a help button in the top right corner
and it opens the user manual to help you
with a lot of detailed information about the catalog and its usage.
With simple search you can choose from three values.
Author, Title or Subject.
To perform a search at least 3 characters must be entered
The Author field has an autocomplete option by default.
The search engine is case-insensitive,
so it doesn't distinguish between uppercase and lowercase letters
and neither does it differentiate accented letters from unaccented ones.
Let's search for a title this time.
Click the Search button or press Enter.
You can sort your search results by several different criteria.
There are limiters on the left side to narrow down your search results.
Click on a record to open it.
On the bottom of the record you can find specific information about the copies.
Location shows you their place in the library.
If the copy is in the reading room, the call number will help you to find it on the shelves.
The status shows you the copy's availability.
Here are concrete examples for the statuses they can have.
This one is in the first floor reading room and it's loanable without restrictions.
SZTE citizens can borrow these for 4 weeks and renew the due date 2 times.
Loanable for the night means you can check it out 2 hours before closing time
and you have to bring it back the next morning at opening.
Someone is currently borrowing this copy and you can see its due date.
Locally usable means you can use it in the reading rooms, but you can't check it out.
4 weeks only means you can borrow it, but you can't renew the due date.
Although in most cases it's possible to reborrow them
if you bring it back in time and no one made a reservation for them.
A location like this means it's not in the library, but in a faculty's collection.
If a copy is in the storage, you can make a request with your student card or Erasmus card.
The copies in the storages can have the same statuses, as the reading room ones.
You can also find online resources in the catalog.
Click here if you want to go back to the results page.
Thanks for watching.
Good luck with your search.

Peace be upon you all
Welcome you all again
Today we'll see how to make this cute flower.
Let's start with the flower center
Make a magic loop, Ch2 up,
Now Rd1: 4Dc in the same loop,
1
2
3
4
then Ch2 , Sc in the same loop,
Here it's our first group
Now Repeat ( Ch2, 4Dc in the same loop, Ch2 , Sc in the same loop )
Repeat the same previous steps till you get 4 groups in this Rd.
At the end , ch2 , sc in the same loop.
Cut off the yarn
Change colour
Make a knot on the hook and Sc in the any ScSt that is plaeced between 2groups.
Now Rd2: Ch3 up,
1
2
3
then start working in the 1st group
2Dc in the next 2sts,
then Dc in the between Dcposts after the 2nd Dcpost and before the 3rd Dcpost
Right here
YO and insert the hook in the flower center and push it through posts and Dc,
then le's get back working in the 1st group,
2Dc in the next last 2Sts,
then Ch3 , Sc in the next Scst which is between 2groups
here we done the 1st group
Now Repeat the same steps in the next group,
( Ch3 , 2Dc in the next 2Sts ,
then Dc in the between Dcposts after the 2nd Dcpost and before the 3rd Dcpost
Right here
YO and insert the hook in the flower center and push it through posts and Dc,
like so
then 2Dc in the next 2St ,
then Ch3 , Sc in the Scst which is between 2groups )
Now Repeat the same prviouse steps all around .
At the end , Ch3 , Sl St in the 1st Sc that we began this Rd with.
Cut off the yarn
Change colour
Pull the new yarn in the 1st Dcst after the Ch3,
Tie it
Now last Rd3: Ch3 as Dc, Dc in the same St,
then 2Dc in the next 8Sts in row ,
after that ch3 up, Sc in the flower center over the 2Rds,
insert the hook in the flower center and Sc ,
and here we've just finished the 1st petal.
Now Repeat ( Ch3 , 2Dc in the 1st St in the next group,
then 2Dc in the next 8Sts in row,
Done with 8Sts,
then Ch3 , Sc in the flower center over the 2Rds,
here we've done the 2nd petal.
Repeat the same previous steps all around .
At the petal ,Ch3 , Sc in the flower center over the 2Rds,
then ch3 , Sl St in the 3rd Ch that we began this Rd with .
Cut off the yarn
try to adjust the petals a bit
Thank you all for watching
and I hope you liked this video and benefit from it
