My Maker Coin!

This piece is a "maker coin" I designed. It takes the shape of a 6cm by 1.25cm disk, but is engraved using various Solid-works features such as fillets and cuts. I also used the circular pattern tool consistently to give the coin symmetry. Use this maker coin for decor or to test the precision of a printer. Since I am an electronics enthusiasts, I decided to show my initials on the coin while at the same time expressing my love for circuits. To the untrained eye, the coin resembles a run of the mill gear-like shape (like many maker coins) and includes an "S," my first initial. However, on closer inspection one finds that it includes several electrical components that together encompass my three initials: "S. H. A."
To explain, the first two components are a capacitor and resistor; the units of which are the Farad and Ohm. When multiplied together, the two units create seconds, representing the letter "S." Fun Fact: in many oscillator circuits, such as the 555 astable multivibrator, resistors and capacitors are used together to create time delays! The next component is an inductor, represented by a chain of semicircles, and the unit is the Henry. This unit corresponds with the letter "H." Fun Fact: inductors can be used in transformers to set up or step down voltages; Tesla-Coils take advantage of this property to make lightning. Finally, the last component is a current source, denoted the unit Amp for its current output. The "A" relates to my last initial. Fun Fact: bipolar junction transistors can be used as current sources, outputting a set current regardless of the supply voltage or load resistance!
