Introduction Our project is a hand-held device that is capable of communicating with any vehicle that uses pulse-width modulation (PWM) data-link layer. Such devices are commonly referred to as On-Board Diagnostic scanners. Vehicles that typically fall into this category are Fords made between 1996 and 2007. In our case, we used a 2003 Ford Mustang […]

The MAX15062 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range. The converter delivers output currents up to 300mA at output voltages of 3.3V (MAX15062A) and 5V (MAX15062B). The device operates over the -40°C to +125°C temperature range and is available in a compact 8-pin (2mm

Description The LT3763 is a fixed frequency, synchronous, step-down DC/DC controller designed to accurately regulate output currents up to 20A. The average current mode control- ler will maintain inductor current regulation over a wide output voltage range from 0V to 55V. Output current is set by analog voltages on the CTRL pins and an external

This instructable fully describes building a PWM driver to control four LEDs from one small Microchip 12F609 board.The original design was called the “Kemper LED Lamp” and I sold a few lamps to several brave folks through my web site. However, I’ve come to discover selling small quantities to a few folks is a major

This is an instructable for making your own PWM (Pulse Width Modulated) flyback driver! The design is relatively simple and easy to make if you have basic electronic skills. In fact, you don’t even have to know how a transistor or a MOSFET works to make this. You only have to follow the instructions. What

This project gives you a simple temperature controlled fan. If the difference between real temperature and the user temperature is high then the fan will run at full speed and if the difference is low then the fan will rotate at slow speed. The speed of the fan varies with the temperature. The user can
