DC motor drive controller control two DC motors of any current or voltage rating, depending on the rating of the relays. The circuit also provides two shaft encoders for positional feedback to the computer, the motor control circuit is connected to an IBM PC parallel port, via a 74LS192 four-bit latch DMX 512 printerport interface page This page c

ontains schematics and software to build your own cheap 64 channel DMX 512 printerport interface. It also contains the schematics for a 4-way DMX booster / splitter and a 12 channel DMX flasher. These designs are based on Microchip Pic 16F84 microcontrollers and very easy to build, schematics Isolated full duplex RS232C interface this self powered interface circuit electrically isolates the TxD and RxD lines from the PC serial port and protect the PC from direct connection to hazardous voltages Isolated full duplex RS232C interface this self powered interface circuit electrically isolates the TxD and RxD lines from the PC serial port and protect the PC from direct connection to hazardous voltages Logic analyzer using the PC`s parallel port record up to 8 channels, use any parallel port, sampling at up to 1 million samples per second, record 32768 samples LPTCAP parallel port print capture system LPTCAP is a hardware and software solution which allows an IBM-compatible PC running MS-DOS to capture print data sent by another PC, or any device with a Centronics parallel printer interface Multi Wire Cable Tester A multi wire cable tester with a separate LED for each wire. Will show open circuits, short circuits, reversals, earth faults, continuity and all with four IC`s Remote control for Windows IR control for Windows, the hardware and software required to remotely control your PC by means of any standard hand held remote...
