what language did u borne into the u-controller?

Picbasic

baba11:
Thanks for taking your time to put us through this
I pray it will be successful
I can't view the cct dias clearly besides,I may want to refer to it when building my own,why can't u make it downloadable also.
Concerning the Rf device you intend to build,it's a two way things I supposed
Any electronics that will work with it will have inbuilt cctry to send and accept the signal,so I doubt how we can incorporate it into existing device without changing its functions.
Don't forget to tell us where we can buy our discrete components
I hope oscilloscope is not expensive sha?
Anticipating in earnest in learning from you,
From your student,
Babanpy.....

I will try and reupload the circuit diagram again. I'm still on where to upload the entire files for this project, may be on 4shared or dropbox. The RF. Module are of two type, the transmitter and receiver module.they seperate units. So u need to build an encoder and decoder circuit that send and receive digital codes. The encoder( transmitter side) and the decoder(receiver side) uses a microcontroller. Always come back to this thread as I will be updating it. Thanks

nisol:
Nice one,

This is encouragement for those interested in electronics design.
Is the copper pour you used for ground continuous?

Copper pour is not yet continuous. I will use jumper to connect to ground(-) when soldering

PCB LAYOUT

ARTWORK

SILKSCREEN

RECEIVER PCB LAYOUT(3D VIEW)

PROJECT FOR THE MONTH OF NOVEMBER

MICROCONTROLLER BASED RADIO REMOTE CONTROL

CIRCUIT IDEA: The circuit is designed to switch on and off any electrical gadget using radio technology . The circuit can switch on and off about 8 different equipments in the house. So you can easily incorporate it into your home wiring.it consists of transmitter and receiver units
An Rf module is used and this is a small electronic circuit used to transmit, receive or transcieve radio waves on one of a number of carrier frequencies. The carrier frequency selected is 433mhz.

APPLICATION
(1)Wireless home automation eg automatic control of lamp, tv, borehole pump, fan etc
(2)Industrial remote control
(3)Wireless alarm system especially in cars
(4)Garage door openers

ADVANTAGES
They are often used instead of infra red remote controls as they don't require line of sight operation
They can operate up to 1km( this depend on voltage applied to the transmitter)
TOOLS NEEDED:
Software: (1) proteus version 8-- as schematic capture and for simulation
(2)PCB wizard drawing the components lay out and current path
(3)Proton basic for writing the code for the microcontroller

Hardware1) pic programmer
(2) Multimeter

TRANSMITTER CIRCUIT & RECEIVER CIRCUIT

Are you interested in learning electronics design? This thread is an avenue for students, hobbyists, do it yourself,electronics technician to learn the rudiments of how electronics circicuits are design. The basic software tools needed in this thread are easily available on the internet for free. The thread will be made as much interactive as possible and you are free to make your contributions, comments and you can even ask question if there are any. The thread will be made to be continuous in as much as there are contributions and flow of information. Circuit ideas can also be shared if you have any. Nothing will be hidden and every detail process involve in the design process will be shown through the use of multimedia such as picture, charts and video if there are any. Circuit diagram, pcb lay out diagram, 3D visualization and prototype picture will be displayed using jpeg picture format.
The software that are used in most of these design are classified as follows 1)The schematic capture software for designing the circuit diagram
(2)The circuit simulation software for simulating the circuit, to see how the circuit behave in real life situation
(3)The pcb design software for designing the electronics components layout and path for current flow. This is achieved either through autorouting or manual routing
(4) The programming software for writing code for embedded system if you are using microcontroller or eeprom in your circuit
The hardware that are needed are(1) analogue or digital multimeter(2)oscilloscope if you have access to any(3)soldering iron/ rework station(4)12v, 6v battery or desktop power supply.
Project topic will be for a month, and within this period you are to make your contributions, ask questions ,build your own version of the hardware. You can only learn through building. Engineering is all about building things.wherever possible it is much better to learn by doing things yourself than by reading about them.
You will find in this thread a lot of suggestions, ideas you can do yourself. I hope you will all manage to do these things as you go along. So let get started as we delve into world of electronics together.

What the op have changed is part of what are change when doing basic service on a car. You're still inexperience with cars , even with new car you still need to change some of these things after many years of use. So be patient to learn

eph12:
They won't release ur parcel if u don't pay so just do it. Always include PO fee in your budget next time.

thanks

santakris:
Please help me check this tracking number RC025318523MY. The guy supposed to post by China Air Mail. Is this number real or fake?

most china air tracking no always end with CH. Where did the seller get this one from

yemi2plus:
At some post offices, they charge before releasing your items.

Always insert for receipt and if they refuse to issue one, know it's fraudulent.

thanks for your reply. I asked for receipt the guy started threatening that he will return it back . Even he was not the one that call me , I track it myself using the site provided here on nairaland. he is always asking for clearance fees

Do we have to pay at post office for your goods especially if what u order is less than 2000naira? This post office guy have always been demanding everytime I want to collect my goods. Claiming its for clearance fee. I always order electronics components which don't weigh up to 10g

kolomax:
Somebody should kindly help me out this is day 36 that my
seller have ship my goods from china via sweden post if I.
Track on 17track.net I don't understand. It @all also on
sweden post it ll tell me no item found I also check on
nipost.gov.ng nothing display please any help here is my
tracking number RE969480147SE

send message or chat with your seller to know which actual shipping agent he used. It could also be switzerland post

Did you ever look at someone and think, "He is
so lucky. He has money, he's in a great
relationship and wow -- what a great career,
being able to travel like that?"
I've done it too. And as my mind entertained
this thought, I would find myself in an often
depressing place overthinking about reasons
why I wasn't as successful as "that guy."
I wasn't so lucky. I wasn't lucky to be born with
good looks or into the right family. I wasn't lucky
enough to have the right education or lucky
enough to be at the right place at the right time.
But as I grew in my career and in my life and by
meeting lots of people from all over the world in
so many walks of life, I made this profound
realization:
Sure, we can be born into it and fall into it. But
so many successful people I met -- from couples
in blissful long-term relationships to successful
career women to billionaires to profoundly
happy people who have very little -- became
"lucky" because they think differently and take
certain actions.
As I thought about my own journey of learning
to deal with uncertainty these days, I realized
that in the absence of luck being granted to us
by the lottery of birth, we all can get a chance to
get lucky.
Here are 21 reasons why some people get
lucky in life:
Lucky people...
1. Work hard... quietly. They don't boast,
toast or celebrate. They do. Toiling away at
their craft day in and day out. They don't
announce it on Facebook or tweet about it
on Twitter. Lucky people get busy working.
2. Surround themselves with positive
people who build them up not tear them
down. Life is hard enough as it is without
having to worry about negative people
slowing you down.
3. Put positive seeds into their mind
every single day. All of us wake up with
sometimes random thoughts that can
debilitate. By proactively choosing the right
words and actions, some people overcome
those morning limitations set by the mind.
They have certain rituals. A morning run,
meditation, prayer or their morning cup of
coffee while walking the dog.
4. Fight the overthinking mind each day.
You are not alone. We all overthink choices
that lie ahead. It can be a daily battle. Is it
in their DNA? Maybe. But increasingly I've
learned that some people -- especially
happier people make a choice to limit their
overthinking mind.
5. Have a clear purpose. Lucky people have
a crystal clear objective. Either to provide
for their children more than they had
growing up or to successfully launch their
business. Whatever their cause, lucky
people have a magnet attracting them to
their goals.
6. Accept imperfection. They don't say, "It's
not a good time right now." But they do say,
"It's always a good time right here and right
now." They know the right time will never
come to them. They have to go out and
make it the right time.
7. They don't gossip or pay attention to
the critics. Lucky people don't get
distracted by the naysayers, doubters or
haters. They don't allow the negativity to
enter their mind. Shrugging off a desire to
gossip or respond to critics, lucky people
smile and keep walking forward.
8. They feel more than they think. They
are often driven by emotion and passion
about their endeavor. Thinking is important
but often we let our minds direct us
forward. And when we face difficult
circumstance, we are conflicted between
what we think and what we feel. Lucky
people seem to lead from the heart not the
head.
9. They focus on the goal, not the plan.
Plans can change. Chaos can interrupt the
best laid plans. But goals don't. Happy
marriage, talented kids, meaningful work
and a successful career -- these usually
remain constant but how we get there can
change over time.
10. They take lots of action. Lucky people
have a bias for trying things, even if they
may fail. They create certainty by moving
forward rather than sitting still. Momentum
goes when your energy flows.
11. They are open to meeting anyone,
anytime. Talking openly to anyone who'll
listen to their ideas, lucky people smile and
engage -- opening up their minds to chance
meetings with strangers where one thing
can lead to another.
12. Remain in the day to day. Letting go of
the past and focusing on the present
moments, lucky people direct their effort at
what they can control right here and right
now. Not worrying as much about
yesterday or tomorrow.
13. They get hurt by the setbacks and the
failures as much as anyone but they
keep going because they know that they'll
come out of it. They have this powerful
belief that tough times pass and that if they
persevere long enough, they'll get through
the failures.
14. They believe in themselves. They're not
arrogant. Lucky people feel that all of us
have this inner strength... this resiliency of
the human mind that can achieve great
things.
15. They're always curious, asking questions
of the simplest things to everyone they
know. They want to understand how things
work. They are explorers wanting to get to
the bottom of things. They welcome new
ideas, thoughts or observations.
16. They know that getting to success is
never a straight line but a path full of
curves and side roads. Lucky people zig
zagged their way through life often in
uncharted waters.
17. Are grateful. Recognizing that life is not a
right but a gift, lucky people act with great
humility.
18. Admit that they're not that smart.
Lucky people become smart and learn by
trying. They read. They toil. Admit their
faults. Apologize quickly and move on.
Recognizing that happiness and success in
life comes from constant learning.
19. They serve others. From launching a new
business to sustaining a happy marriage
requires serving someone else than
yourself. Lucky people give generously to
others through their effort in their jobs,
careers, business and their personal lives.
Their effort is found on ensuring others
have what they need before their own
needs are met.
20. Know that they're not born lucky. They
become lucky by studying, working and
refining their craft. They are not born smart
but become smart by reading, developing,
cultivating and growing. Lucky people don't
count on luck. They make a choice to think
differently and to take action.
21. They're hungry. They want it badly. They
believe they have something of value to
give to the world and are aching to give it.
Lucky people jump out of bed in the
morning. They sacrifice -- giving up the
luxuries of the modern world (TV,
Facebook, etc.) -- so that they can get to
work fulfilling the promise they make to
themselves.

I want somebody to pls give me the address
of where I can buy quality inverter components
and transformer in Lagos. thanks
my email: muhammedadio@gmail.com
p. no: 08082698875

try oshodi main market or alaba international

macklef:
OP yes, you are not far from the truth.
You raised very realistic points and i can't help but agree.
Enterprenuership is sweet but it is not easy. Enterpreneurship is also diffrent from business deals, some mistake this together.
If i get a contract to supply certain items or execute a quick deal, thats business deal.
Enterpreneurship however is an art. A longtime building in the process. It dosnt really pay off in the short run, it takes years to get to that level.
Personally for me, illd keep my good job, amasss wealth thru savings n be using it to sail a business, rather than learn 1 yeye skill 100 people on my street are already doing.
Sitting in one shop and be waving at people passing by.

To drive entrepreneurship money is needed, all ye school leavers with no job running into enterpreneur, it pays only to make you survive(put food on the table) not to make you the man you want to be, well maybe in 15yrs time tho.
How many tailors own smooth cars, or bid makers, or soap makers or all this petty enterpreneurship.
Wanna be an enterpreneur? Take the risk, invest on publicity, invest on structure, invest on service. Uld smile.

And to all you info marketers overating enterprenuers pls stop. Ur hungry ur marketing hunger to other people by deceiving them. Like our importers that will tell you they buy item for 50 naira n sell them for 1000naira, dey will not tell you total codt was 600naira o. God is watching you all

many of this info marketer are hungry lion. They just do copy and paste and look for fools who they can sell to. Generally entrepreneurship is really overated. Those who even preach this are not successful in what ever they are doing. At times I look at some of these preacher and felt sorry for them. I see where a petty trader who even claimed to be an entrepreneur , hardly make end meet. All stock in shop is not even up to 200k.

Nairobi:
Truth is OP, it's not easy to be a married man. When you get married too you will understand.
A man is usually influenced by his wife in marriage. Usually and you as a man may feel it is better to offend your parents than offend a wife.

I really don't know how to put it because it wouldn't really sound balanced.
What I am certain of is that most women are not really good at heart. Trust me. Women are very evil, wicked and subtle.
They can cause problems in a mans life and family especially towards his family.

My wish is that may the good ones among the women find a good man to complement them as well.

you are surely married. Actually talking from experience. Most married women always pretend to be nice especially when it involve family matters , and people see the men to be wicked not knowing that 'he who pays the piper calls the tune'

LAX89: He's a typical Nigerian, that's why he's worrying about comfort first.

the guy love pleasure more than hardwork. what's the benefit of the office and IT gadgets he wants to procure in a farm settlements. Will all those lead to increase in productivity that may increase his profit margin. He is just a pleasure seeker

When will the data expire? Is it daily, weekly, or monthly.

Is it for a day, week or month

onlinebenefits: but going to school does not guarantee you success

being entrepreneur does not also guarantee you success. There are also so many broke entrepreneur. Only few successful ones are celebrated. Entrepreurship is overrated.

Who are the real entrepreeur? An arm robbers, fraudsters, prostitute and even a common petty trader, who hardly make 10k in a month will call himself or herself entrepreneur. No innovation, no outstanding skill , some dont even the technical and marketing skill to run a business and still claim to be an entrepreneur. Some business are just jack of all trade, commodity 'me too' product, usually with poor system in place, labour intensive, dependent only on one or two people. No residual income, no brand, poorly leveraged products, and most of these businesses have too many competitors as a result the owner dont build relationship just do transactionc, the salesperson always looking for the sucker ,always selling as a one off deal. And someone still someone still businesss owner an entrepreneur.

UjSizzle: It's general knowledge that the average Nigerian is a Jack of all trade.
Talk about sports, and we all become football analysts.
Fashion, and we are suddenly icons dictating who wore what right and who committed a crime of fashion.
Religion, and it becomes a battle of whose doctrine is the closest to what Christ teaches.
Medicine, and we're doctors without certificates overnight, diagnosing illnesses with our eyes and giving drug prescriptions .

Politics. Everyone(or almost everyone) agrees those at the helm of affairs of our nations are making a mess of things. All i see in here is people complaining and cussing everyday without giving a single solution to the problems at hand. Or has the country gotten to a state that there's no longer a cure?

Think ruling a country is piece of cake? Lets see how well you can handle it.

So, my question...
Since we have a good number of political analysts and judgmental people here who claim to know better, please be kind enough to share what you will do differently if you are Mr. President??

its always easier to complain, condemn,castigate, curse than to profer solutions to problems. So don't take people by their words, its easier to talk, but to walk the talk is where the problem is.

Caseless2: I will make sure i'm not as clueless and weak as gej.

But ure still clueless for making this type of comment. The quetion is what will u do differently if u find urself in position of GEJ
