- In order to program the ATTINY25 microcontroller, a temporary connection must be soldered to the programming pins.
- The battery is charged using another temporary connection.
- The end of the "pick" should be sanded down to remove any solder mask/copper and to smooth the edges.
- The via under the battery should be covered with a small piece of tape to ensure that there is no unintentional shorts.
- Shrink tubing should be placed on the strobe LEDs to direct the light to the guitar strings.
