Available at toy stores and online, such as here. Note, this project uses the modern electronic toy, not a vintage mechanical one.
Shottky Diode
You can use a regular power diode such as the one below, but a proper Shottky diode is even better, it only has a ~0.3V drop vs. closer to ~0.7V.
Optional
You can replace the toy's graphics with your own, or the handy downloadable graphics included in the guide. Vinyl sticker paper for laser printers works well, such as this.
