It's been a challenging week for the project, but results are currently looking good. Since the last blog update, all components have been ordered and have arrived (with the exception of one or two stray parts we're still waiting for). Since then, circuits have been fully designed in both schematic and physical board layout form to facilitate testing of the components and associated circuit designs.
The project is just about to move from theory to practice, with a non-programmed hardware prototype hopefully ready in a weeks time. The final list of required parts has been compiled, with particular attention to reliability in outdoor conditions and useful battery life.
