Mutable Instruments Clouds is an excellent granular synthesizer module. With this kit, you can quickly (and relatively easily) make a clone of Mutable Instruments Clouds.  

This kit includes:

1) A pre-soldered Clouds PCB with pre-flashed ARM chip (no need to spend hours dealing with hundreds of components or soldering tiny ARM chip pins). These PCBs have an ENIG finish (higher quality than other DIY PCBs offered) and are electrically tested.
2) 7 premium-quality D-shaft potentiometers, 1 of which is dual-gang.
3) 12 Thonkiconn jacks
4) 4 LEDs
5) 7 black, D-shaft Davies knobs
6) Nuts for potentiometers and jacks
7) 2 switches and switch caps
8) 1 power cable
9) 1 LED push button
10) A beautiful black and gold Oscillosaurus Clouds panel.

Beginner to intermediate through-hole soldering skill is required. Since this is a pre-assembled PCB, little technical knowledge (and no surface mount soldering) is needed to complete the Clouds build. If any questions arise, I will try to help as time permits, but recommend one of the many DIY communities online for assistance (Facebook, Muffwiggler, et al.).
