Electronics

A decibel (dB) is 1/10th of a bel (B), so 10 decibel = 1 bel. A decibel value by itself does not mean anything. It expresses a ratio, typically of power or intensity, on a logarithmic scale.

In electronics, voltage and current amplification are calculated as 20 * log₁₀ and power as 10 * log₁₀. Logarithms are the inverse of exponentiation. For instance, the logarithm to the base 10 of a number is the power to which 10 must be raised to produce that number.

Using this DC Boost converter (XL6009E1) you can easily convert 5V from the Arduino Nano USB to 12V. This setup should come in handy to power the SID chip. 

This SX04 2K LCD with controller board screen just got delivered. I will try to connect it to an HDMI output. RPi maybe? Believe it or not I have actually made an unboxing video.
