Professor Mark Csele - Projects and Hobbies

Nixie Thermostat 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 PIC-based Temperature Alarm - An alarm which warns when temperatures fall below or rise above user-settable limits. I use the prototype in my cold cellar to warn when canned goods are about to freeze and another version to control the temperature of the carboy in which I ferment wine. Features a user-friendly two-line LCD display.

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

Radiocalc - Convertisseur Radio Universel (tm)

Radiocalc - Convertisseur Radio Universel (tm)

Manual, Formulas, IS Units, Glossary

Besides classical functions and dB conversions, RadioCalc includes a converter of Power to field strength commonly used for EMC/EMS test-set-up. Also impedance can be represented as a function of reflection coefficient (somehow like an electronic Smith-chart). This and many other functions are obtained by clicking into the arrow of the "Conversion off" window.

Thanks to RadioCalc the different dB charts are obsolete by computing the ratios of Power (W) or Voltages (V) according to dB = 10*log(P2/P1) ou dB = 20*log(V2/V1). Just for a trial : type 100/10 (or just 10) and push the dB button as the 'W' mode is chosen, the result will be 10 dB, then choose the 'V' mode by clicking in the V button (in the Quick dB window) push again dB, the result is now 20 dB.

For power conversions and dBm calculations, please check that the appropriate Impedance is set. The reset value is 50 Ohms. For getting familiar with the powerful functions of Quick dB, just push 'C', then push for ex. the '4' on the RadioCalc, then push consequently all 10 buttons (dB, dBµA, dBµV…….) and see the result and try the same in the 'V' mode.

Circuit Fantasia - Present and Invent Electronic Circuits

Circuit Fantasia - Present and Invent Electronic Circuits

This site presents a completely novel concept in electronics education as an alternative to the classical approach. Based on human imagination and intuition rather than formal reasoning, it is implemented as an interactive multimedia electronics product.

It is intended for students, teachers, hobbyists, inventors and for all those who do not make do with traditional formal explanations of electronic circuit phenomena. The product consists of tutorials, collections of circuits, basic principles and heuristic tools implemented by means of dynamic text, interactive step-by-step controlled animations, hyperlinks, hidden explanation buttons and sounds associated to the circuit operation. Created by Cyril Mechkov.
