K1001 - 8 Channel Serial Servo Controller, Assembled & Tested

Ozitronics - Electronic Kits

K1001 is an 8-Channel Serial Servo Controller based on the Atmel 89C2051 microcontroller. It accepts RS232 or TTL serial data from a computer or microcontroller and outputs PWM (pulse width modulated) signals to control up to eight RC servo motors (as used in radio-controlled model airplanes, cars, etc.).

Unused servo pins can be reconfigured for digital output to drive on/off devices.
Up to four controllers can be multi-dropped on a single serial port for controlling up to 32 servo motors - more on request.

These pages are extremely useful for an entry into the Robotics Wonderland, a little electronics ability is enough for you to start learning robotics. Robotics is the only science that covers everything almost .. Mechanical, Electrical, Electronics, Embedded, Computing, Networking, Automation and Wireless Technologies. Some advanced robots include probably every science and skill known to mankind. So make a start today. Learn Robotics!

SPC3 - 12 Volt 9 Amp / 10 Amp Solar Power Center Kit

The SPC3 kit contains all of the circuitry for a medium-sized solar power system. It includes a solar charge controller for battery charge regulation, a smart on/off power switch with automatic low voltage disconnect operation and a built-in white LED lighting system. Additional lights and other 12V devices can be connected to the load terminals and controlled by the SPC3. The SPC3 can regulate up to 9 amps of incoming solar power and can switch an external load of up to 10 amps.
The kit includes:
  • A high quality double sided, silk screened circuit board.
  • All of the parts required for building the board.
  • A schematic and wiring diagram.
  • Easy step-by-step assembly, alignment and usage instructions.
CirKits is a division of SolOrb.

Multi-Instrument Digital Assistant - PIC16F84A

Multi-Instrument Digital Assistant - PIC16F84A - "It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver."

The Engineer's Assistant - Erik Grindheim

"This compact instrument is intended to be a digital laboratory tool for hardware and, in some cases, software debugging. It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver"

Multi-Instrument Digital Assistant – PIC16F84A

Serial code receiver The serial code receiver receives 42 bytes and displays them in both HEX and ASCII. The baud rate is selectale in 8 steps from 1200 to 115200.

Logic state analyzer This is a one-channel logic state analyzer. It fetches 300 single bit samples in a selectable rate from 25ms to 1┬ÁS (40 Hz to 1 MHz in 16 steps).

Frequency counter The frequency counter displays the frequency with up to 8 digits on the LCD. The refresh rate is 500ms.

Logic probe The low and high logic levels are displayed by LEDs which are OFF if the probe tip is floating.
