The Journey: Start to Finish

Photos of me soddering the wires, switch, and battery holder together. This was  the first step to learning how the overall functionality of my project would work.

Videos of me testing the mortar/vibration system as well as using the heat gun to safely secure the soddered wires etc. The heat gun was used to warm up the heat shrinks around the exposed parts of the wire.

Photos of the attached vibration system, underneath my hopper. The location of this allowed for the entire system to shake, which helped the coins make their way through the hopper and ramps.

Videos of how my coin sorting ramps work. The acrylic worked well, allowing the coins to mostly slide down easier. I had to remove some excess hot glue because it was causing too much friction between the ramp and the coins and stopping them from sliding properly.

Photos of the split hopper system and coin sorter ramp once attached to one and other. The ramps were attached at a down sloped angle, and tilted to the right so the coins didn't slide right over the holes and skip to the others.

Videos of the attached coin sorting system both working and jamming. It introduces a problem I had to quickly fix by removing some excess hot glue that was blocking the hopper slot on the left as well as widening the slot to assure that quarters could make it through.
