Capacitance Probe A simple probe can be made using insulated wire. The insulation is then the dielectric of an cylindrical capacitor with the inner conductor as one plate and the water as the other. The probe is not suitable for distilled or very pure water because it is not conductive enough. It works well even […]

AN6877 is linear AF level meter IC produced by Panasonic and it is commonly found on many audio equipment. This chip is no longer manufactured by Panasonic and finding replacement chip for AN6877 is also quiet difficult. The circuit described in this article is design to replace AN6877 base LED drivers and it is based […]

Altera and IBM have designed an FPGA-based reconfigurable processor to improve the performance of supercomputers. The firms have created the first FPGA-based accelerator for a POWER8 CPU which features shared virtual memory between the FPGA and processor and so improves system performance in high-performance computing (HPC) and data centre applications for data compression, encryption, image processing […]

Mork is adaptation of Nanu nanu Microchip PIC ICSP for the STM32 based vcc-gnd or Maple mini. Both STM32 boards are inexpensive boards which don’t cost much more than the Nano 3.0 yet they are far more powerful. One complication though for the vcc-gnd, is that it comes with a serial boot loader which is […]

The BOLT microcontroller board utilizes the Microchip 18F2550 with built in USB capabilities. Utilizing a 2k ‘boot loader’ this leaves a great deal of flash RAM for C programming using MPLAB and the C18 compiler. The BOLT board comes in two versions. LITE which has the 18F2550, 8 LEDs for PORTB, four switches and a […]

Minimum noise, easy speed control and a high power, those are another reasons why to decide for GreenTech EC fans from EBM-Papst. A term „EC fan“ (electronic commutation) is generally used to mark energy-saving AC fans. In fact, these are DC (brushless) fans with AC/DC module and other electronics. EC fans reach up to 90% […]

Switching DC-to-DC voltage converters (“regulators”) comprise two elements: A controller and a power stage. The power stage incorporates the switching elements and converts the input voltage to the desired output. The controller supervises the switching operation to regulate the output voltage. The two are linked by a feedback loop that compares the actual output voltage […]

The good and high precision capacitor meter (Capacimeter) inductor meter (inductimeter) auto range lc meter for pic 16f84 or pic 16f628 and display lcd by phill rice Construction of an apparel that allows measure inductors (Inductimeter) and capacitors (Capacimeter), knower like LC meter, using PIC (16f84 or 16f628) and display marries in LCD. Translated of […]

Dual Motor L298 H-Bridge Control project can control two DC motors connected to it. The circuit has been designed around popular dual H-Bridge L298 from ST. This circuit has current sense resistors for both H-bridges to provide voltage which enables this board to use in stepper motor applications. Specifications Motor supply : 7 to 46 […]

Even in these tricky financial times, opto-electronics is offering sufficient funding draw to allow entrepreneurs to start technology companies. One such firm is cork-based InfiniLED, which emerged from the Tyndall National Institute, becoming a company late in 2010. Unusually for a start-up “we were in the strange position of spinning-out of the Institute with a […]
