2. Counter The whole counter design is based on the PIC micro-controller 16F876A. The latter includes several peripherals and just a few of them are used in this project. The most important in this project are two internal, hardware counters/timers called TMR0 and TMR1. The TMR0 timer generates very precise interrupts every 100 microseconds (10kHz) […]

1. Spectrum-analyzer project 2007 update Since the development of the wide-band VCO almost 10 years ago, the whole spectrum-analyzer project with all related accessories: tracking generator, harmonic converter, storage-normalizer, marker counter and accessories developed by other experimenters (Darko S57UUD) have been published in many different places: magazines “VHF-Communications”, “AMSAT-DL Journal”, “CQ ZRS” and the book

Parallel Port 3 Axis CNC Driver, Opto-Isolated, Unipolar Steppers Controls 3 Unipolar Stepper Motors, for use with CNC Machines. Simple driver with automatic coil shutdown, to ensure efficient operation. Opto-isolated for protection of the P.C. Supports most parallel port based CNC software, such as KCAM. Supports up to 20 watts per Phase. Or 2 Amps
SD/SDHC CARD SOUND RECORDER For SD with PETIT FAT File System see SD Bitmap project For sound playback with EEPROM see Doorbell The PIC16F876A’s ADC digitizes the sound and store it in the SD or SDHC card. The firmware works for SD or SDHC cards only, for old SD (before 2009) use ver1 firmware. Do not use SDXC cards

Design Summary: Our group designed and manufactured a miniature robotic vehicle that conquers various terrains. The vehicle was designed with a track system which is powered by two DC motors. The motors use a Quadruple half H ‐Driver in order to drive the motors in both directions. The track system incorporates a four bar linkage for each tread. These two linkages allow each side to be independently raised which gives the robot multiple configurations.
