Well of course I installed an LED 😂.
At first I went with a blue one but then decided to make it really special and put in an RGB LED. Because why not? 🙌🏻

Now the mod is complete. Next stop - replacing tone sucking pedals with decent ones and maybe wiring power underneath. But no rush there - I really doubt I'll ever play outside of my place again 😂.

A simple but satisfying fix...
A basic press on battery powered light brought home from a local pre-school were it is used as a learning aid.
It was not turning on, and changing the batteries (4x AA) did not help. Opening it up I saw the problem. The bulb was blown! Also, it was directly soldered to the switch, so replacing it would not be a simple swap.
Instead, I replaced it with a couple of LEDs and a 150R resistor. Then, some hot melt glue to hold it all in place ✔️

次はWorkshop Tool（工房で使う道具）の製作に取りかかろう。
直巻モーターの回転制御回路を自作します。
回路はこれで良いと思う。
自分で使う物なので急ぎはしないし、外観も気にしない。
ちゃんとしたケースは値段が高いのでジャンク品のパソコンの電源のケースを使う予定。
@jmrubillon I was wondering if there was something like, say, blue LEDs are 50 times more luminous than green LEDs, but our eyes are 10 times more sensitive to green than blue. So a resistor ratio of 5 - 1, would make the two appear equal, thus when mixed the result would be a balanced cyan. Similarly for yellow, when mixing red and green.
I only want to use the 3 primaries plus yellow and cyan, and the LEDs are either on or off.
I accept that I may be overlooking many facts...
Trying/struggling to "balance" the LEDs in my RGB LED...
Each LED in the RGB package has a different forward voltage so I have worked out the resistor values to give a current to each LED of around 6mA.
However, I am finding that, say, yellow (red + green) is a little too green.
I know that some LED colours are brighter for the same current, and our eyes are more sensitive to some colours than others.
Has anyone managed to work out resistor values/ratios to balance all this?
