RTOs vendors Move to support automotive standard - 04/01/99 EDN Design Ideas: NOTE: File contains many designs. Scroll to this one. The Tornado for Automotive tool suite from Wind River (Picture) supports the OSEK automotive operating system initiative. Tornado includes MotorWorks, an OSEK-compliant RTOS that the company acquired through its partnership with German software house 3Soft, and a fully integrated tool suite. The OSEK automotive-industry initiative defines a scalable operating system for resource-limited systems Design by Graham Prophet
Rush Converter for the Car - This converter allows an ordinary AM car radio to receive 15.42 MHz (WRNO). A famous talk show is transmitted by this station. The unit should be constructed in a metal box with antenna connectors compatible with the car radio. The converter includes a relay which automatically bypasses the converter when power is removed. A single power wire comes out of the converter box and goes to a power switch located in a convenient spot. (The unit is connected to ground through the coax. __ Contact: Charles Wenzel of Wenzel Associates, Inc.

Simple Circuit Car Preamplifier & Artificial Earth - Especially for car audio installations, can be used for any single supply system __ Designed by Rod Elliott ESP
Simple Circuit Helps to Protect a Vehicle-Reverse Camera - 10/06/11 EDN Design Ideas: Add a delay to prevent short power pulses as you shift through reverse. Design by Aruna Rubasinghe
Simple Circuit Transistor Based Motorcycle Alarm - Motorcycle Alarm Circuits: This is an even simpler transistor based motorcycle alarm. The circuit features a timed output and automatic reset. it can be operated manually using a key-switch or a hidden switch. By adding an external relay, it will set itself automatically - and/or immobilize the machine - every time you turn-off the ignition. it's easily adapted for a 6-volt system - so it will protect your "Classic Bike". - Now With Free SiMetrix Circuit Simulation. __ Designed by Ron J.
Simple Circuit Vehicle Loop Detector (inductive loop for driveway etc) - Another Simple But Very Effective Circuit __ Designed by G.L. Chemelec
Simulating Solar Sprint with Spice - Simulation programs running on digital computers allow computer designers to predict the operation of new chips, aerospace engineers to predict the characteristics of new airframes, and architects to predict the thermal characteristics of new buildings, all without building anything. __ Designed by Chuck Wright
Solid-state relays simplify Monitoring electric car battery-voltage - 02/19/04 EDN Design Ideas: Figure 1 shows the propulsion system of an electric vehicle. it includes an electric motor, drive electronics, a mechanical transmission, vehicle control/power management, a charging system, and a battery. The long-term performance Design by Robert Krause, Fairchild Semiconductor, San Jose, CA
Speed Alarm for Cars - in normal suburban driving you pass through so many different speed zones that it can be a nuisance having to switch speed settings. The speed display can also be a distraction. This circuit eliminates the display and the need for speed selection. Each time you exceed a particular speed setting (eg, 40km/h, 50km/h, etc) , a piezo buzzer will beep.__ Col Edwards - Co Silicon Chip Electronics Magazine
Speed Limit Alarm - Wireless portable unit; Adaptable with most internal combustion engine vehicles __ Contact Flavio Dellepiane, fladello @ tin.it
Switch-mode Power Supply for a Tube Car Amplifier - To minimize heat loss on any transistor, I use two pass FETs. in the car, input voltage is either 11.5-12.5V (engine off) or 13.5-14.5V (engine on). in the first case, T1 and T2 are fully ON, no need for heatsink. in the second case, T1 is OFF, T2 ON, all voltage and power excess __ Contact klausmobile @ yahoo.Com
Synchronized multi-spark Module (SMSM) for Electronic Ignition Devices (EID) - Multi-spark ignition is very useful especially in the case of startings at low temperature and at low rpm range. Basic idea, is to apply to spark plugs instead of only one spark, a spark-burst having big energy. in this case, combustion of air/fuel mixture is much better and the emissions are more reduced. in addition, through burning improvement, the consumption of fuel can be reduced __ Designed by Dumitrescu Danut |
