The Journey is the Reward
- how much I can learn from the effort?
- can the things I learn be extended to other projects?
- is the end product useful, novel or amusing in some way?
What is important is the experience of building something, of facing challenges and answering them in a satisfying way. The main beginning goals of this project were to get some exposure to graphical LCDs and the wireless module, CYWM6935 from Cypress Semiconductor. A LOT of learning happened along the way and choices had to be made.
For the impatient, here's a video that shows the Spectrum Analyzer progressing from raw prototype to "Version 0.99 Beta", or close to "first engineering prototype". Video is about 2:07 in length:
Basic Parts Costs
Depending on how you choose to implement this project, your component and raw materials costs could be as little as about $30 USD, or over $50. That doesn't include additional tools like a breadboard or a microcontroller programmer, if you don't already have them.
