From aliexpress This is a cool light bar that reacts to music and sound unfortunately it does not have a battery inside in this version
This is a super piano from Yamaha. The Clavinova clp-840 has a great sound and feeling. Find the service manual here of the CLP-120 as I could not find the CLP-840 one
