Op, if u can't edit the pix, then change d topic of the thread! Simple

Op is just being mischievous. That pix is not a pix of osha main market, rather the river bank close to ose market where yam traders and other food stuff traders are!

Sometimes I marvel at d kind of ppl that comment on topics in NL. If I may ask, if mtn doesn't have a solid foundation, then which network has.
Infact how old are u sef

a1solution: MTN should first improve their internet service / voice call before investing in other areas cos a house without solid foundation is bid fall in no distant time.

Malawi?
Is that a name of a dog?

This space is for sale!

May be dis software ll help!
Proteus 7.0
Try and see if u can get d cracked version. U can start from there!
That's how I started, cheers

schoolboi: I would love 2 know more about this embedded system in terms of pratical.

Shut up there! Always quick to compare naija with ghana with fake info and statistics.
Airtel has 1g data for just N1400. And stop displaying ur ignorance in a public forum.

onatisi: even in ghana bb isnt common ,because there is no need for it ,mobile internet data is too cheap so why use a bb.the major reaon bb still sells in nigeris is due to the cheap internet acess it affords its users.ie in ghana here u get 250mb for just 4ghc a month on glo which is 400 naira but the last time i was home i was paying 500 for 50 mb on etisalat,that was when i thought it makes sense to buy a bb and use in nigeria than normal good smartphone.if the cost of mobile internet is reduced considerably in nigeria believe me ppl in naija will throw bb away and go for better mobile phones.nigerianslike to show off

How much is ur budget. But p3 laptop, wot can it achieve for u. In dis modern day world, I don't think p4 can achieve much and talk less of p3.
My advice, go for better but cheaper processor laptops like celeron and centrino.
And I think with 40k, u can get or I can get for u good lappy(not p3 nor p4)

Oga maleeq, I no knw say u na mod. Thanks for ur contributory comments in ma other thread.
and if I may ask, how much does seun pay u guys?
And les I forget, its ur birthday, happy birthday to computer guru!

Like how much did u think the sensor will cost cos a dealer is telling him 80k

usisky: PS: what your friend needs is a flow rate sensor. There are some ultrasonic flow rate sensors too. Google is ur best friend; use it.

Am not sure mikroC supports such fuction u wrote below.
Anyway, how good are u in proteus, cos I lyk simulating my designs before building the components.

usisky:


You are most welcomed! You can tinker with it as you wish.







Actually, i don't use MICRO C compiler. Though i've got the AVR version and the 8051 version(i only work with those two Micros). But don't fancy it much. Though it has got more than enough libraries.

@Bold. Your compiler understands what ascii is; it is part of the library.

How does your C compiler understand what this means:

unsigned char TestAscii = 'A'; ?

You can see that the variable has been assigned an ascii character because the compiler know what that is.

In the same fashion, when you receive an ascii character over the serial port; depending on what it's intended for,all you got to do is check against the expected character. e.g

If((TestAscii=SERIAL_IN)=='B'){execute next step here;}

If all you need is to display the incoming character on an LCD for instance, then absolutely no need to look up the received character; just send to LCD directly.

But if for some reason you're sending ascii characters representing decimal integers 0 - 9 , and your controller needs the real value and not the ascii equivalent. All you do is subtract 48 from the received characters. 0 is 48 in ascii.

i.e either you do this: RealVal= AsciiVal-'0'; or RealVal= Ascii-48; same thing.

If you can give me an idea of what applications you work on that require such look up table, may be i can give better explanation.

Lwkms
Which one be 'this space is for sale' again!

Truman155: Apple propaganda lamfao........... ........., THIS SPACE IS FOR SALE

Ve being using mikroC compiler for a long time and am not sure if it supports such features.
And since u know it, tell me how it works. I mean having the compiler to receive ascii characters without looking up d ascii table!

usisky:


@ bold. In truth, if you write codes in C...then its really not necessary looking-up the ascii table to translate. All you gotta do is send your ascii characters from the PC/host controller to your microcontroller. You use their index positions in the ascii table to do your math. e.g the ascii value of "0" is 48(30 HEX), so when you send characters denoting different integer states from your PC app., all your controller gotta do is subtract 48 to get the real integer values needed.i.e On the other hand, if all you need is to display such characters on an LCD or somtn' ,then ain't no need to translate. If is for pure control, then send characters as HEX-DEC(compressed into one byte). hope it makes sense?

Thanx for the vb code, I ll take a look @it later!

Y should I put myself into all these stress using ultrasonic sensor and its calculation while I can easily get d water sensor from the market.
May be wen we start talking about d speed of water flow, then that one can make sense.


Also, I remember, one of my friend is doing a school project that involves checking the speed of liquid flow in order to determine the amount of crude extracted from a well. Maybe with this sensor that that can measure speed of liquid flow as well, then d job is good as done!

usisky:


There are different ways to solve this problem. One way is to use magnetic reed-switches(sensor) arranged vertically across the height of the Tank at various points. A magnet strapped to a floating mechanism aligned close to the reed-switches will indicate current position along the Tank height as it gets filled. Every time the magnet passes along any of the reed-switch point, the reed-switch closes; this is now detected by your micro-controller and action taken accordingly. There are other ways as well:

1)Using a floating mechanism
2)Using a Liquid sensor
3) e.t.c


But all these are intrusive(require contact with medium). Here,i will give you a professional way to implement it. This uses ultrasonic ranging technique. With this scheme, you don't only detect the water level, You can as well tell precisely how fast the water is being pumped and also the exact water height from the base of the Tank. Ultrasonic sensors are positioned at the top of the tank; You use ultrasonic ranging to determine all necessary information. Things you need to know:

1)The Thank Height
1)The Point were the ultrasonic sensor are positioned at the top of the tank

Using simple math, you can get the actual water level,with the Tanks' base as the reference point of measurement.
Normally, you'll need two sensors(Receiver and Transmitter). But there are bi-directional ultrasonic sensors, and this will be best for this design.

As for determining the rate at which the water is being pumped; this is fairly intricate...you'll need to understand how to use ultrasonics in doppler shift velocity estimation. Google is your friend; use it! Detecting presence/absence
of PHCN i would assume is fairly straightforward. Just me 2-Cents!!

I don't know why u ppl keep arguing wot embedded system and wot its not.
For lay mans understanding; embedded system is any system that uses micro controller to perform actions which are usually control actions. Infact most systems that involves micro controller and performs control operations can be said to be embedded system.

U mean u did all these projects:-

usisky: Hey mates!. No need for the bickering alright? I am quite sure we all come on this forum cos we wanna contribute meaningfully.....So let that be the focus.

i will give my email as soon as i get somexpression of interest from u folks. thanks

U took words from ma mouth. By simply analysing most poster and their responses, u see all of them thinking that Iran has got the technology to rule the world are all muslims.
And u might still wonder where they get their news from; u can't imagine bloody West hating TV like Press TV.
In their dreams its good to ve a rogue nation as world power provided its muslim country.
Keep-on-dreaming!

emmatok: Wonder why Muslims always look to rogue Nations like Iran.
Countries like Saudi, UAE are far ahead of Iran, but you hardly hear them Bragg.

I know u must be a muslem; go and vent ur anger on the american-egyptian who showed ur prophet as a gay and terrorist or better to d french cartoonist who drew ur prophet naked and not me.

Very soon, Iran ll see wot they are looking for

Ayatullah: @Dondbuzor, U are definitely a great dunce as your name suggests. Iredeemable fooool and America/Israel slave like you will always not appreciate the great strides Iran has taken in the field of space science and technology and other goodness the blessed and glorious Islamic Republic of Iran has achieved. Your masters, America and Israel are doooomed if they dare touch Iran.

judezion :

Intresting thread!where did you study @dondbuzor.?if you don't mind my asking.and for the record kip it up.

Studied @uniben
Was lucky to have some few friends who where equally good in electronics and programming. That's where I drew my inspirations from.
Thanx for ur comment shaa.

Bro u too much!
U just made my day.

drzed:

First of all, dont make the mistake which many Nigerians make when submitting proposal.

The best approach is to introduce the project, describe the problem and simply highlight the solutions that will emerge. NEVER (and I repeat) NEVER ever describe the methods, technique, process or the actual approach to reaching the solution. This will be done ONLY after trust and guarantees have been established. Let me explain.

For example:

1). You have identified how Company A will increase profit at half the cost of providing a popular service (lets call it Service X).
2). In your initial proposal, just simply overview (i.e. give an introduction) of who you are and how your expertise matches their business model, then;
3). Discuss why/how they are losing money through their current procedures (this is the part where you catch their attention by exposing their weakness or inefficiency) and then;
4). Explain in the proposal that profits can be increased by reducing costs of providing Service X; by following a new approach called Solution Y, which you developed originally.

Then you can now submit the draft proposal which is just a skeleton without flesh. But also have another version of the proposal which contains details of HOW they can arrive at Solution Y by following your brilliant concept. But keep the detailed proposal secret until the time is ripe (See STEP 9 below). If they ask why you are withholding details, be honest: Tell them you are protecting your idea.

5). At this stage, (assuming that the company truly wants/needs to cut down cost of Service X) your phone will be ringing off the hook with calls from their representatives. Agree to meet them, and prepare a PPT presentation of the same material in your original/skeletal proposal, just in case. They may/would want you to make an oral presentation (besides, its a professional to always be ready).

6). Before you go get legal representative (lawyer) to prepare a Non-Disclosure Agreement (NDA) and have the idea/proposal copyrighted as well. This is much more than putting letter C in a circle. There are official ways of copyrighting and it is cheap. For effizy, you can even get a dark suited lawyer to accompany you. There are samples of NDAs online that you can modify by yourself, but having a legal firm prepare one with their letter head and/or having a lawyer accompany you is more effective in Nigeria. They wont want to mess with you.

7). If they are honest and truly require your service, they will sign the NDA. Just make sure you have audio and video recording of the signing process, especially IF a lawyer is not present. Dont let them know you are recording the process. Pssst: ask Otedola for handout on how to capture crooks digitally. Audiovisual recorders in the form of spy pens, ties, fez caps and wristwatches abound everywhere even in Nigeria of today.

8'). If they are dishonest (and 75% of your potential Nigerian clients fall into this category) they will not agree to sign the NDA. In that case, walk away. It is better to "die" with your original idea than have id1ots steal it, while you gnash your teeth each time you watch it being executed. Walk away and approach their competitors or find a willing investor, in which case, repeat STEPS 1 to 7 above.

9). For the honest 25%, after the NDA is signed, you can now bring out the second detailed PPT slides (or detailed documentation) which contains the HOW aspect of your proposal. Dont expect this NDA thing to happen overnight. They will likely consult their own lawyer and re-invite you for the signing after some days/weeks.

10). If they breach the terms of the NDA i.e. execute it without you or disclose it to some third party without your permission, (explicit or otherwise), you can confidently approach Mohammed Fawehimi and similar legal folks who like to take on (i.e. sue) such crooked Nigerians head-on...sometimes for free, or sometimes for a fixed percentage of the spoils of war! But you can also reach a journalist who is looking for a story like this to make a name for him/herself. Trust me, big companies and big men dont like being rubbished in the media, especially if their is audio or video evidence.

11). Did I mention that you should dress VERY well each time you visit your clients? Once your potential clients (especially the crooked 75%) perceive you to be a hustler or 'hungry man', they will be tempted to out-muscle you out of your ideas. First impression matters. Borrow your friend's decent car for the trip if you have to. Sounds funny, but it is true. Even in developed countries: a successful looking consultant has bigger chance of tying up a deal than a tattered-looking, job-seeking, desperate-sounding hustler. Sad, but true. Ask yourself, if you were the CEO of a Telecoms or Fast Food company, will you not be more comfortable parting with 10 Million Naira to a well-dressed consultant, rather than to a ragged-looking fellow?

12). Also bring along a colleague or two each time you visit them. Even if they are not your employees or business partners, the presence of two or three of you in a room will inspire confidence in your consultancy. A one-man show is not usually well-respected and does not always look professional. Think about it: you are the minister of Railways and you want to do a deal with a German company to deliver High Speed Urban Trains to each Nigerian City. Will you be happy if only ONE German showed up all the way from Munich? Or will you be more impressed if he came with a team?

Well, thats my two cents based on experience. Enjoy your success. Remember, there is no such thing as luck. What people call luck is simply a matter of preparation meeting opportunity. Be prepared and know your worth. I am also assuming that you have a registered business, if you dont, you are essentially wasting your time trying to do consulting work with private or public entities.

cheers

Not really. I always verify their news with cctv and RT, most of the times, its 99.999999% accurate.

Ok, I remember, a new method of cleaning pooo.
Sil.ly fo.ol

shymexx:


What can your country build, slob??

So, you're American now?? Bwahahahaha

Get your country on Iran's level before you critique their achievements...

I think u re the silly one here. Wot brought about nigeria into d discussion.
Is it nigeria that is threatening other countries like US and Israel with war.
And let me say it again, if this is all iran can design(I mean this type of drones). A drone that got only 100km in 3hrs, then they are doomed.

shymexx:

Can Nigeria manufacture this?? You guys are silly and ignorant...

Iran manufactures: long and short range missiles, war planes, civilian airplanes, submarines, drones, warships, air defence systems etc...

Nigeria is still 40 years behind them!

An olod.o like u bragging about intl. Politics.
Wot do u know? Tell me.
Didn't u read in d news wen iran was boasting that I ll wipe out israel from the map of the world.
And let me ask again, is it this type of drones that can fly for only 100km in 3hrs that iran ll use in achieving such feat.
Or rather, olodo like doesn't know that most iran technologies are borrowed(or bought from russia). U didn't u read in one of the articles posted where they bragging on their ability to repair submarines which they bought probably from Russia.
I think foo.ls like u who are always first to bragg about their knowledge of world politics and yet have nothing in their brain except akamu should be barred from the internet.

YemiAdisa:

I must say a big thank you for this because you have just taken the words out of my mouth.
Most Nigerians don't know nothing about world politics and most especially the Iranian military capability. You guys need to read books and stop watching "porns" lol




Please stop commenting on issues you don't know nothing about. Also, stop watching CNN,


Fox News and the likes when it comes to global politics; they are all feeding you with rubbish!
The Iranian president has never made the above statement you mentioned, it is just the "war propaganda" Israel is feeding people like you.

Iranian president said "THE WORLD NEED TO WIPE OUT ZIONISM FROM THE MAP", he did not say Israel. Then you should have asked yourself why ZIONISM and not ISRAEL or JEW. Do you actually know the differences between Israel, Jew and Zionism? Please go and read more books and always engage in intellectual debates/conversations with open minds.

My argument is simple; is this all they could put together in order to wipe out israel from the world map as they boasted.
Mark my words, iran is destined to doom. Maybe they are banking on russia and china to come to their aid wen the war starts.

texazzpete:

Iran is one of the most advanced countries in the Middle East. Not up to israel's level but they build formidable short range missiles.

So this all they can manufacture? Inspite of these their threats!
Iran is destined to doom, mark my words.
