ECE Project, I need HELP!!! Empty ECE Project, I need HELP!!!

Post by Guest Tue Sep 02, 2008 9:04 pm

please help me naman mga fellow cubers!

may project ako sa aming minor subject... ECE
kailangang gumawa ng circuit..
pero using transistors,..

at ang naisip kong gawin e stack timer...
para may project na ako, mat timer pa ako! Smile

nag research na ako sa internet at dito sa forum natin..
kaso, masyadong simple...
ang kelangan ko e medyo kumplikado ng konti para maganda ang maging marka..

please reply naman kaung mga halimaw sa electronics...
pakita kau ng schematic diagram at parts list...

ang kailangan nga pala e ganito;
1. wag sanang push button yung switch, kung pde, sensor.. (siguro pde na yung nakita kko dito sa forum (gamit ay lata)
2. may ready signal (yung green at red lights) green means ready
3. kung pde, yung mga gagamitin ay madaling mahanap sa mga bilihan ng electronic parts

thanks sa magrereply...
baka nga pala isipin nyong project ko ay sa iba ko pinagagawa...
ndi kami tinuruan magdesign ng ganyan..
ang project namin ay humanap ng circuit at gumawa ng ganung circuit (ndi kasama yung pagdedesign)

pare ko'y tagal ko ng binababalak gumawa nyan kaso wlang time
di ako mamaw sa electronics pero
yan ang interesadong interesado ako, hehe,

bka may mahihiraman ka ng "circuit maker" na software
dun ka muna magdesign at pag gumana dun gagana sa prototype yan
ang naiisip ko dati na mga parts eh "555 timer" para accurate yung time,
tpos "7 segment display",
mga logic gates ic para sa 2 mong switch
yung switch lng ang di ko masyadong magets kung hindi push button
di ko din kasi alam sensor na gamit sa normal stackmat eh
siguro LDR pwede, o kya infrared, lagay mo,
kung wlang mabibilhan dito ng mga parts
sa alexan sa megamall meron or kung wla pa din
quiapo tol, sa raon... hehe, layo...

try mo paglaruan sa circuit maker ang mga yan,
andun naman yung mga parts na yan
ska patulong ka sa mga ece dyan sa school nyo,
nireformat pc ko eh kya nwala ung circuit maker
sna mkatulong bro...

ECE ka nga pala! nawala sa isip ko engineer.. hehe..
ndi ako marunong umunawa sa ganyan e.. hehe.. pero nagreresearch pa din ako sa internet...
saan kaya ako makakahiram ng circuit maker? hehe..
thanks...

search mu lng sa net ung circuitmaker, pwede mu i-simulate ung circuit mo, tsaka ung eagleCAD software pag may circuit ka na...

sa palagay ko naman ata wala sa pagiging complicated ung circuit eh .... mas maganda pa rin ung naiintindihan mo ung ginagawa mo .. di ka matututo kung deretso ka sa mahirap na cirucit gusto mo magsimula ka sa basic logic na prototype oh di kaya amplifier na transistor. kasi ung sinasabi mo na stackmat combinational circuit na yan saka kelangan mo na ng background sa microcontrollers para mapagana mo ung LCD .... suggest lang magsimula ka sa simple lang para mas matutunan mo gumawa ..... or kung gusto mo naman pagawa ka na lang sa raon hanapin mo lang ung tindahan ni mang werner kahilera ng kalsa un ng deeco

sinong raon? sinong mang werner? saan yung deeco?
hehe..

computations lang kami tinuruan...
ang pinagagawa kasi e humanap lang ng circuit at gawin e...
ndi ko kelangan intindihan nang maigi yan kasi ndi talaga namin linya yan..
pero sa tingin ko, naiintindihan ko na basics Very Happy
i think tama na yun...

hehe.. thanks anyway..
research na lang ako sa internet Smile

When ba ang submission niyo pre?
I just saw this topic, and it caught my attention since I am as well an ECE.

Well anyway, here is my simple help:

To create a timer, ang pinakacommon gamitin na device is the 555 timer.
Since your project only allows you to use transistors (though impractical), you can actually use the equivalent transistor circuit of the LM555 package. You can view the equivalent circuit on the following site:

http://www.uoguelph.ca/~antoon/gadgets/555/555.html

From that, you can now design your own timer circuit, but instead of using the LM555 IC, replace the whole part by the equivalent circuit. You can use the basic counter circuit found on any Electronic textbook (it is a very common circuit though), or the circuit found on the following link:

http://www.electronicsforu.com/EFYLinux/circuit/july2004/ci-05_digitalstopwatch.pdf

Of course, take note of the equivalent pins of the LM555 IC comparing it with the equivalent circuit.

What you have in mind, is use a sensor instead of a manual push button switch. Easiest of them, would be a light sensor using an ordinary LDR, pairing it with an operational amplifier, a driver transistor (to drive the output from the OP AMP), then a relay (acting as your switch). You could actually find this basic switching circuit on any site. Just try to browse.

Once you have combined all these circuits, you will have now have your own up-timer. And for the functionality, do not assemble the circuit yet or buy the parts. Try to simulate your circuit using available Circuit Simulation Tools as mentioned by them: ORCAD, Circuit Maker, etc. Basing from my experience, it is better to simulate circuits using ORCAD, considering it gives you almost all the data you want. Circuit Maker is an easier tool, but with significant limitations as compared to ORCAD. For the PCB Layouting part, I suggest the Eagle Tool.

Those are things that I could think of, so far.
Hoping these would do help.

thanks tol!!
unfortunately, tapos na pasahan ng topic...
pero try ko if pde pa magpalit...

kung ndi naman, gagawin ko pa din yan ndi dahil para sa project, kundi para sa sariling timer...
hehe...

siguro, kapag may free time.. thanks...

uhmmm.. pde naman gumamit ng stopwatch na nabibili diba? (gagawin ko yun kapag ndi as project)
tsaka, pano ba yung sensor? light sensor? mahal po ba yun?

thanks ng madami! Very Happy

Regarding sa light sensor, as I have said, you can use an ordinary LDR (light dependent resistor). Such device is very available sa lahat ng mga electronics store..... I guess..... and sobrang mura..... 15 to 50 pesos..... depende sa size..... The behaviour of the LDR is..... dependent on the amount of the ambient light..... it changes the value of its resistance..... Utilizing this behaviour..... you can very much use it and pair it with an OP AMP to create a basic switching circuit.....

I guess that is all..... Tapos na pala yung deadline..... Smile

tsong, gusto ko kita tulungan.. i'm ECE graduate.. medyo hilig ko din gumawa ng mga circuits nung nagsstudy pa ako.. tanong ko muna kung anong year ka na sa ECE para malaman ko kung anong parts ang pede sa design mo.. and anong subject mo kelangan? kasi kung may alam ka na sa "microcontrollers" may idea ako para sa project mo...

thanks!

uhmmm.. mechanical engineering po kinukuha ko e..
so, basic lang nalalaman ko...
as in, SUPER basic... Smile

i see... thanks for the info..
thanks din at binibigyan mo ng time itong problema kong ito... Very Happy

tapos na deadline, pero i think mapapalitan ko pa topic kasi wala pa kami nasisimulan,...
(pero problemahin ko muna semis ko Razz )

thanks uli! happy cubing!

OT:

hello fellow cubers,

nadaan ko lang tong topic na to habang may hinahanap.

then nabasa ko sa mga previous post na marami mga engineering students dito.

what if kung gawa tayo ng thread about sa profile natin as engineering student/graduate.

suggestion ko lang po kasi interested ako sa mga pagkakaparepareho nating mga cubers. hehehe
