Anyone undertaking this project should have access to standard tools -- pliers, diagonal cutters, wire cutters and strippers, soldering iron and solder, multimeter, electric drill and brad point bits (more on these later). Experience making PCBs is also required.
Break Out of Your Pod -- Low Fidelity Audio -- High Fidelity Cool
Several early commenters have noted the lack of pictures. There are now pictures detailing the preparation of the Altoids tin, battery holder, speaker, switch, audio jack, audio cable, and overall installation of parts and final assembly. There are also several pictures of the board with all of the electronic components installed but there is not a step-by-step walk through of this process. The main image for step 5 (Soldering Parts to PCB) has image notes identifying each of the parts.
If there are any additional pictures that you think would help the construction process, please let me know.
