DIY timer

[CyberPunk]

wah!!
got diagram!!
im damn interested =D

 

[www]

maybe tonight will upload. quite busy larr..

 

[CyberPunk]

okok
cool!
thanks bro!
u taking e&e?

here the part for simple timer.....

Ic555 X 1
Resistor 1M ohm X1
Capacitor 1mF 16volt X1
Capacitor 0.01mF X1
Capacitor 100mF 16volt X1
Diod 1N914 X2
Relay X2

Cost~~ RM20++ jee. without labour. DIY free...
Can apply for any application include turbo timer.
will upload circuit diagram if interested.

can provide more details ahh??...
the resistor 1MOhm on how many watts??...
the capacitor 0.01mF how many volts??...

very interested... but wat if i want the timer to run more than 20secs??...

 

[www]

sorry, got problem can't upload the diagram. maybe later....
resistor---1/4 watt
capacitor--- ceramic type.
this timer can run more than 20sec depend on resistor and capacitor. the list for sample only.

here the calculation, duration(t)= 1.1 X R(resistor ohm)X C(cap. farad).

This looks interesting ;)

Hmmm....
Very interesting......
I do mine once but failed coz the power flow all the time.....
My 1 can adjust 1....
So,urs can last how long....??
But good info there....
Still waiting for the diagram...:)

thanks for the update dude... will be waiting eagerly for ur diagram upload... will start as soon as ur diagram is done...

 

[www]

still got problem maaa...
who's interested drop ur email. i will send by email.
very sorry.

Thanks....

 

[www]

still prepare the diagram.

 

[CyberPunk]

okay!
^^ Thanks bro!
will be waiting for it

i oso want!!!

pls check ur email. that circuit operate like cyberpunk need.
calculation given for sample only. can change the resistor and capacitor depend what delay ur need. connect relay R1 to load you want to control. this circuit maybe not suitable for turbo timer. but can try it. maybe got jerking. for turbo timer need modify that circuit or try the other circuit. happy DIY.
need feedback....................

 

[CyberPunk]

have this circuit been tested before and safe to use?
what do u mean by got jerking? how does it jerk?
not suitable for turbo timer??
then do u hav the turbo timer circuit arr?? :D :D :D

hmm.. correct me if i'm wrong. a turbo timer is needed in a turbo-ed car so the turbo won't be damaged right? What's the use of installing in a NA car then? IMHO, the engine can cool itself over time and there's actually no need to let the fan run.

cyberpunk, if you want to make a turbo timer, all you need to do is find the wiring to your ignition and then use a relay to keep the "on" position after the key is taken out. if your idling speed is high enough, there should not be any jerking.
