I have hot-glued my Arduino Duemilanove to the battery compartment lid of my Maxitronix 500-in-One electronics lab, making for a portable Arduino lab that includes:
- 8 LEDs
- Photo-transistor
- CdS cell
- Antenna coil
- Tuning capacitor
- DPDT swtich
- 665-hole breadboard
- 8 SPST switches
- 8-digit LCD display
- 7-segment LED display
- 4-bit embedded microcomputer w/ keyboard
- Speaker
- Transformer
- 50kΩ and 100kΩ potentiometers
- Compartments and trays for loose components
The Arduino aligns with the spring terminals of the 7-segment display, such that the case closes perfectly.
