#### Schematic
[SpriteTM](http://spritesmods.com/) has an excellent schematic (first one) [here](http://spritesmods.com/?art=doorbell&page=2). But we can go more minimal (hint: 'forget' the capacitors).

Soldering to the SD CARD (not micro sd):

#### Construction
You're free to come up with a technique to connect the components together as long as you keep the [schematic](#Schematic) in mind (or not ;0). Among popular techniques are: breadboarding, [manhattan](https://hackadaycom.files.wordpress.com/2016/05/0gfwt.jpg?w=400) (great tutorial [here](https://www.parasitstudio.se/building-blog/manhattan-style-pedalbuilding) btw) or [deadbug](https://m.eet.com/media/1180890/thermoml.jpg) circuit design, more crazy circuits [here](https://hackaday.com/2017/09/05/non-standard-circuits-jazz-for-electrons/). Can't decide how to connect the components? Just start soldering up the components pin by pin, either starting from the SD card or the ATtiny. Another approach is to think about what type of device you want to create; will it be a wearable device, a pocket device, a mantle piece? Or what functionality it should have (easy to replace batteries? updatable songs? reset button? skip track button?). Below is an description for a dead-bug style compact unit with replaceable battery, departing from the pins on the SD card in respect to the orientation of the ATtiny.
