DIY Electronic Lab Tools

Below are listed various electronic projects that I have worked on over time. Each project has been tested to at least the breadboard stage, whereas, many have been fabricated on either PCB or veroboard. In all cases, full details of the working circuit (including schematic diagrams, circuit descriptions, component selection) and any difficulties encountered during construction (and fixes, alternatives or work-arounds discovered) are given in detail.

Details of the various projects are available by clicking the links in the following tables which list projects by either category, project title or ID number.

Where I encountered new components, circuit ideas and or concepts I have not previously used, often I produced small test circuits to focus on learning the new item. Details of such experiments and learnings can be found on the Component Testing pages.

Sometimes I developed software (using either Visual Basic, Microsoft Access, CSS C++, or Excel spreadsheets) to help with various projects. Such programs, modules and or source code can be found on the Downloads pages.
