To generate sparks ~ 20 kV, the car ignition coil can be used, with 12 vdc primary switched by a 2N3055 transistor controlled by a 555 timer. You can also find discarded CRT monitors and analog TVs, with HV flyback transformers. Those generated 20-25 kV from 12 VDC, too. You may even use the original driver circuit and reve (...)
Hello Friends, i have made an project to dislay the time on 2*16 LCD with pic is working fine with 12v dc adapter(input ac 230v) which is converted into dc by LM7805 and a .01uf capacitor. it is working fine and LM7805 is also normal. Now i am planning to place this unit in car. so to power up this board shall i co
My friend where are you living in Bronx ? :shock: Did you consider rather to use some hidden buttons, say two, and you need to press right combinations of them. But what will stop thief to open hood and add plus wire direct on HV coil (bobina) ? I remember that people when whant to save car, remove distribution arm or complete distribution
I assume the 12v or around there is the same where ever I tap into it. I basically need to send a pulse to the go pro when I turn the ignition on then when I turn it off I need another pulse, not sure how an op amp would be able to do this? Need to detect the rise of the 12v then the fall and send a pulse on the leading and tr
Hi I thought I'd have a go at building this very simple circuit using an IGBT to drive a car ignition coil. So far I've had no luck getting it to work, with T1 failing after a couple of seconds running. The IGBT side seems fine and never fails. I've tried numberous things such as replacing T1 with a 1 amp mosfet, a 240 volt mosfet and (...)
Build a Tesla coil, Jacobs ladder, a car ignition coil, the flash circuit of a disposable camera or electronics of a fly zap racket
whats a "vic circuit" ??? if you mean car coil - the ignition coil - it is basically a pulse transformer, and the secondary pulse voltage is like 40,000 volts + you mean applying a bridge rectifier to that ? !!! maybe you should explain what your trying to achieve ?
I WANT TO CONTROL AUTOMOBILE'S ELECTRONIC circuitRY INCLUDING ignition BY A 16 BIT 4 WORD DIGIT I.E (1244) ENTERD THROUGH HEX KEYPAD. IT MATCHES THE ALREADY SAVED PASSWORD AND THEN ALLOWS CURRENT IN WHOLE circuit . ALSO I CAN EDIT PASSWORD AFTER ENTERING OLD PASSWORD . AFTER I GARAGE MY car I PRESS "LOCK" AND IT GETS (...)
i want to design a circuit that receives sms and perform the task. i want to put that in the car to control several features like auto lock, ignition cutoff, etc but to much confuse how to use the 89C51 in serial communication with Nokia 3310 or others please send me a sample program and circuit...thank u sooo much in (...)
hi just take that wire from the car (there is a ignition wire) and connect it to a MCU input. (ofcourse you will need a protection circuit for the input and the mcu) also use TVS diode. good luck.
Have anyone used this before to generated spark? I am doing something sort of like lighter. Have to light a fire using a car ignition coil. I never use an ignition coil and 1st time to deal with power circuit as ussual i only do digital low power circuits. I use the cicuit from
Hi I need an supply for 12 and 24 v , begin whit Switch regular of on semi mc34166, i have a cuestion how protect my circuit of ignition moment, in this transient the supply of car have peek 0v ~ vcc+40% , in this moment i lose my data in ram. thanks for u comments!
