Planning Laboratory

Laboratory 1.0: designing and soldering a logic probe. Prototyping  electronic circuits

Lab 1.1 [10 Sep]

1.1.3. Laboratory prototypes

This preliminary laboratory activity is for learning to solder electronic components using basic tools. There are many books and web pages that can teach you this important skill for prototyping electronic projects.     

Project tutorial: Designing a logic probe, a simple instrument

Let us conceive a simple instrument: a logic probe, to visualise logic values and detect digital signals. It will be a kind of bridge circuit between ET (1A), CSL (1B) and CSD (2A) where analogue comparators will detect digital voltage thresholds and fast signal transitions.
