Suunto PC Interface
This page contains GIF images of the circuit diagram for the Solution interface, the PCB artwork, the board layout, a typical side elevation of the assembly, a parts list, some hints, and a brief overview of troubleshooting. This is a...
Aladin
Whoever thinks about reproducing an interface for the Aladin should first of all be aware of the fact that there are two different versions of the interface. The first version, easier to assemble, enables the user to transfer dive data...
Suitable for driving the microprocessor power supply LT1587 LT1431S
Figure (a) illustrates a microprocessor power supply circuit utilizing the LT1587-3.45. Figure (b) depicts a power supply with an adjustable output voltage constructed using the LT1585. Figure (c) showcases a computer power supply circuit formed with the LT1584 and LT1431....
Massage digital display circuit
The display circuit is utilized in a typical digital massager. At the heart of the control circuit is the microprocessor EM78156, which receives manual operation instructions. It triggers two transistors to supply voltage to the DC motor (A +, A-...
Microprocessor power supply watchdog
The circuit monitors the input to the microprocessor's 5 V regulated supply for voltage drops and initiates a reset sequence before supply regulation is lost. In operation, the resistor-capacitor combination Rs and Cj forms a short time constant smoothing network...
Microprocessor programmable interval timer
The microprocessor transmits an 8-bit binary code through its 8-bit I/O bus, which is necessary for programming the ICM7240. This is followed by four WRITE pulses directed to the CD4017B decade counter. The first pulse resets the 8-bit latch, the...
HIP6302V Microprocessor CORE Voltage Regulator Multiphase Buck PWM Controller
The HIP6301V and HIP6302V control the microprocessor core voltage regulation by driving up to four synchronous-rectified buck channels in parallel. The multiphase buck converter architecture employs interleaved timing to increase ripple frequency and minimize input and output ripple currents. Reduced...
Migrating from x86 to Power PC
When signing into developerWorks for the first time, a profile is automatically created. Certain information from this profile, such as name, country or region, and company, is made public and will be associated with any content posted. Users have the...
shutter
A microprocessor-controlled shutter control box for electrically driven shutters, such as the MELLES GRIOT 04 IES 003 and ILEX electric shutters. Older view camera lenses often feature shutters that may develop issues due to age or wear. While a clean,...
