I compiled the badge components into a bill of materials to compute the final cost. Despite having a motor and a large footprint, it should be competitively priced.
I designed an accessory PCB for the spinning badge. It only features a 555 timer and flashing light because people expect an IC and lights. The circuit is one I used for a PCB business card.
My partner suggested a vinyl record was a spinning accessory, so I designed a simple LP. I plan to buy silver and gold markers to let people personalize theirs.
I designed a simple arrow to be part of a decision-maker. People can write choices, like restaurants or activities, then power on the spinning arrow for a random time and accept the final position's decision.
The REV2 boards arrived, so I put one together and listed the necessary changes. I shrunk the board by 40%, arranged the components more appropriately, and planned to connect the battery holders with bolts.
I measured and added my battery holders' mounting holes to the motor panel. One stuck out like a pimple but will be covered after assembly. I drafted a rudimentary wrench to help people tighten the nuts when they assembled their badges.
The rest of the summary posts have been arranged by date.
