A collection of information on a variety of topics. Finished projects, Some ideas, Repair tips.by San Bergmans, Oisterwijk, The Netherlands.
A pair of dice is the first small example application I present here. The interface is nothing more than 2 sets of 7 LED's, arranged in the form of two dice. One push button per die completes the interface circuit

CD4093 - Quad 2-Input NAND Schmitt Trigger
The difference be-tween the positive (VTa) and the negative voltage (VTb)isdefined as hysteresis voltage (VH). All outputs have equal source and sink currents and con-form to standard B-series output drive.
CD4093 is a very useful chip, as it has a Schmitt-trigger and it is a nand, cmos, low power. It can be even made to function like an amp in some configurations. It was used in debouncing circuits, oscillator circuits and input signal conditioning of digital circuits.
DMM range and AC-DC mode Logic
If you had a train of square pulses from a magnetic sensor or proximity sensor. You could use this as a monostable or singleshot to reject noise and get a clean square wave from a messy input.

A Sound understanding of Physics and Chemistry is needed for stepping into “Electricity and Magnetism”. We have to move young minds into Electronics even before High School, as a part of Science itself.
e-Learning Resources – Physics at Exeter
- Practical Electronics II and Electronics for Measurement Systems
- Feedback and Temperature Control
- Computer Interfaces for Instrumentation Systems
- Troubleshooting Op-Amp Circuits
The ability to diagnose and cure problems in a systematic manner is an exceptionally valuable skill. In PHY2028 students are given a heap of components, a breadboard, and measuring equipment.
Feedback and Temperature Control
System Model, Types of Feedback Control, On-Off Control, Proportional+Derivative Control, Proportional+Integral+Derivative Control, Proportional+Integral Control, Third-Order Systems..
