Hi, i just complete build tach light, but fail to add some blinking function using NE555 ic.

can it tap out from led dot signal to NE555 circuit so i can get blinking LED as shift light.

 

here the diagram..

 

Just think tu tap NE555 circuit but fail, any suggestion anyone. THIS DIAGRAM WORK FOR TACH ONLY

Done ;P simple circuit

 

Nice project

 

thats actually pretty cool

 

ha kinda is cool

 

Looks great! Thanks for sharing.


A boost gauge referenced off the map would be interesting as well.

 

Hey here the project circuit :D hope you enjoy it

1 x LM2917N
2 x LM3914
1 x 7809

21 x LEDs

1 x 1N4007
1 x 1N4148
1 x Zener diode 12 Volts

1 x 220 Kohm variable resistor
2 x 1 Kohm
3 x 10 Kohm
1 x 22 Kohm
1 x 2.2 Kohm
1 x 470 ohm

Electrolytic Capacitors:
1 x 470 microFarad 25 Volts
1 x 2.2 microFarad 16 Volts

Polypropylene Capacitors:
3 x 100 nanoFarad
1 x 47 nanoFarad
1 x 1 microFarad

 

Here the circuit and adjusted rev light i using transistor to power up blinking circuit

 

make me one

 

good night, you know tell me if it is possible to put this circuit in a karting 2
times? input signal comes from the coil, which gives current to the spark plugs?

 

Here you can refer it from this manual, this project installation same with product on manual.

yES input signal from -Coil that gives current to spark plugs.

 

Hey if you interested, i got the PCB drawing in ExpressPCB , you can etching and solder up those component your self

 

Wow I can't believe how old the 555 timer ic and 3914 bargraph driver is and yet it is still so versatile to this very day! Good job btw

 

looks interesting. Light up the RPM numbers and it will be set.

 

I am interested in the PCB drawing to make one of these. I would appreciate a copy please.
