Automotive Relay Drivers using the ZVN4206AV: Protection Free Interfacing
with Avalanche Rated MOSFETs - Zetec Semiconductors
Applications Notes An alternative solution is provided to usual large
package Darlington effected relay driver. The ZVN4206AV has been designed,
processed and rated to withstand significant energy within breakdown
region. This allows part to absorb back-emf and transient
energy, reby allowing lower component count circuits. (app note

Automotive Speed Indicator - The speed of an automobile can be
indicated by detecting the pulses generated by the ignition system and
causing an LED to light. The circuit utilizes a quad NOR gate IC chip. Two
of the gates are configured as a one shot multivibrator… [Randy Linscott,

Bar-mode LED-cluster sequencer - Bar-mode LED-cluster sequencer. Can
drive up to 16 clusters (circuit added 6/07) |
|
Bicycle Back Safety Light - this circuit has been designed to provide a
clearly visible light, formed by 13 high efficiency flashing LEDs arranged in a
pseudo-rotating order. Due to low voltage, low drain battery operation and small size,
the device is suitable for mounting on bicycles as a back light, or to put on by
jogger/walkers (schematic added 06/07/08) |
|
Bike Device - For starters, I mounted a 7 amp-hour gel-cell on the frame so
that I wouldn't have to keep buying batteries for the headlight. The headlight
is a 12 watt Malibu light from Home Depot complete with a very good diffraction lens.
The horn is a scavenged auto alarm from Walmart. I just use the horn with…. [Luhan

Bike Light Flasher (Randy Linscott) - This circuit will flash an
incandescent light that you can purchase from Radio Shack. Adjust the VR's for your
flash requirements and make sure that the lamp you use is designed to put out high
brightness. (electronic design added 08/08/08) |

Brakelight Flasher - This is basically a flasher circuit modified to turn on
and off a bulb instead of a LED. It uses a 555 timer IC working as an astable
multivibrator. The flashing rate can be varied from very fast to a maximum of once in
1.5 sec by varying preset VR1. The ON time of circuit is given by:
TON= 0.69xC1x(R1 + VR1) second and OFF time is: TOFF= 0.69xC1xVR1 second.... [Radioland.nt.au] |
|
Brakelight hookup - This circuit is NOT a pulser or flasher! What's so
special about this circuit? Well, the first third-brake light I installed I had to
pull a wire from the Third Brake Light all the way underneath the carpet to the
brake-pedal-switch and I thought it would be easier to pluck the signal of both
brakelights via the trunk. Bench-test your circuit first and apply power to the
circuit,.... [Tony van Roon's circuit] |
|
Breakdown Beacon - This is a very simple automotive project you can keep in
the boot of the car for those unfortunate occasions when you break down. I hope
this will not be very often but the chances of a breakdown are always greatest on a
cold and windy night, just when you need some sort of warning to say you are laid-up
at the side of the road. |
