“I present, below, a collection of projects I have worked-on over the past few years. For over a decade, I had taught both embedded systems (microcontroller technology) and digital signal processing and practice what I preach….”

Professor Mark Csele – Projects and Hobbies

Nixie Thermostat – A heating and cooling thermostat employing technologies spanning fourty years from the unique Nixie tube display, circa 1960’s, to a PIC 18F microcontroller, circa 2006.

A High-Powered Power Backup Inverter

A High-Powered Power Backup Inverter – The working prototype of the 2 KVA inverter is complete. Fed from an array of lead-acid cells totalling 600 Ah (at 12 Volts), it easily drives real-world loads such as single-phase motors. The inverter has been tested and found to operate at an efficiency of between 71% and 82% driving a variety of both inductive and resistive loads

These are Tiny Chips that integrate the Microprocessor and Peripheral chips in a compact size with low power consumption. PIC Microcontrollers from Microchip are the evolved computing digital devices that go into many gadgets and intelligent equipment. These are easy to program and reprogram and even protect your code or IP.

The PIC has the math power. The memory, the I/O ports are integrated in the chip like 8051. Some may remember that Microprocessors like 8085 and Z80 had all these functions in chips outside and used to consume more power. Then came CMOS and better IC technology. The 8051(now avr, atmega)and PIC Micro are entire boards in one chip.

Introduction to PIC Microcontrollers,Baseline PIC Architecture and Assembly Language, Baseline PIC C Programming, Mid-range PIC Architecture and Assembly Language – Quite a few are free and can be read online.

Starting with PICmicro controllers by Wouter van Ooijen. PICmicro is the brand name for a family of microcontrollers manufactured by Microchip. The PIC acronym stood for Peripheral Interface Controller, but recently Microchip has renamed their chips to PICmicro. Within this family the flash-microcontrollers (16×84, 16f62x, 16f87x) are ideal devices for hobbyists and low-volume professionals.

Learn to program in C with FED – This manual will take you through the process of learning C from variables through constants to pointers and then structures and unions. Most of the examples are standalone and are as small as possible to enable the purpose and effect to be easily understood.

PIC 18F4550 USB 16F877A IO RS232 Eval Board

The design is essentially a double evaluation board for the chips 18F4550 and 16F877A. It contains also a MAX232A serial module having two transmitters and two receivers with the ability to connect either to 4550 or 877 microcontroller. Each microcontroller port ends up to a pin header in order to give interconnection capabilities to the board for future experiments.

Unique, hands-on electronics workshop for children and adults. In the workshop participants solder electronic components onto specially-designed circuit boards.

MadLab – Inventive electronic kits

MadLab has been made possible through the generous sponsorship and support of the Edinburgh International Science Festival, Zot Engineering and Microchip.

MadLab - Inventive electronic kits

A really useful tool for the budding electronics engineer – a digital frequency meter. New and improved version.

  • input signal range from about 15Hz to 8MHz
  • new feature – bypass switch for low-frequency TTL-level signals from 1Hz
  • internal accuracy +/-1Hz
  • 4 digits of displayed accuracy
  • input conditioning amplifier sensitive to 50mV

MadLab presents an absolute beginner’s guide to electronics. Following this short course will lead you from basic ideas about electronics right up to an understanding of how the simple MadLab kits actually work.

How would you let your PIC-Micro Board Interface with your Cell Phone (Network). These Cards and Designs will help your Embedded System to be Controlled or Monitored using a simple Wireless Device Networking.

PIC-GSM at Olimex 

Using PIC-GSM you can easily monitor and control your home from everywhere with your GSM cell phone. You can switch on and off relays remotely by SMS. You can monitor the status of your GPIOs or toggle them. You can establish a call to the GSM module and speak or listen on the audio channel of the board. You can monitor the temperature from several digital remote temperature sensors.

ProtoBoard started life as ProtoPOD.It was designed as a prototyping POD for use with BitScope making development of new (PIC based) POD designs easy.

PICuP ProtoBoard – BitScope Designs

PICuP ProtoBoard

It is a small (2.6″x4.0″) PCB comprising a 20 x 13 thru-hole prototype grid pre-wired with 4 busses and a 40 or 26 pin header with pads for connections into the circuit.

Application

PIC ICE Probe – When you need to analyse an existing circuit that has a PIC in it you may wish to observe signals at the PIC pins to diagnose a fault.

Data Logging – ProtoBoard includes a serial interface which can be used as the basis for any number of data logging projects. The PIC may be programmed to monitor some external variables and then transmit the data to a remote PC as required.
