The aim of the project is to build a logic analyzer for home use using FPGA. The device uses a Xilinx Spartan 3 Starter Kit (DO-SPAR3-DK) evaluation board manufactured by Digilent. It features a XC3S200-4 FPGA with 4ns propagation delay and 3840 cells. Onboard are 1MByte of 10ns SRAM and plenty connectors that can be […]
The aim of the project is to build a simple NPN and PNP transistors tester and to identify their pin layouts, i.e. EBC, ECB. When you place transistor in correct position, the LED will light up. This circuit requires few parts and it easy to obtain many of the required parts from your local store.
LCFesR meter is a precise, wide range meter that can measure inductivity (L), capacity (C), frequency (F) and equivalent series resistance of a capacitor in-circuit (ESR) based on AVR ATMega88PA-PU microcontroller. It can be easily built with homemade one or double-faced PCB and available electronic components. dr. Le Hung, project designer, explained that measurement of […]
The application presented here is software driven device that allows the user to test the servo motors used in remote control operated models such as cars, boats, planes and so on. The tester is developed based on M16C/28 microcontroller. There are many opportunities when one may need to test a servo. Either the servo has […]
