0.3mA is alnost two orders of magnitude lower! The 20mA rule of thumb is very simple. It is by and large the most common maximum rating for current for many LEDs. It is not to be exceeded, so using it as a rule of thumb just means getting the brightest possible light with no risk of burning out. I generally use 0.25 or 0.1mA for modern blue or green LEDs as indicators
It’s a “small company” thing. HMRC requires I sign up for UK VAT explicitly with no exceptions - and double accounting for almost no profit I can’t do… however! If you already signed up for an account I’ll send you an email tomorrow with a link to the programmer on eBay (Tim of Tim’s Retro Corner is selling them in the UK) Unless you’ve already found it :)
The 20 mA "rule" is about 20 years out of date...even in 2005, we were using 15-20 mA for LCD backlights in mobile phones, and the output at 20 mA, 20 years ago, was eyeball-scorching, when the LEDs were viewed directly!
Exactly. But the myth prevails and you still see that dreaded 220 ohm resistor in "Arduino tutorials" on youtube. But if we work together we can keep our collective vision intact ... eventually. :)
yaaa bro super sensitive to green...... we used to be hunters we needed to distinguish our food from the various things undergoing photosynthisis everywhere around whatever animal we were after.

Great project that just keeps getting better. Good job!
Thank you - it's a team effort! :)

Correct, hoped nobody would notice that order of magnitude blunder - not sure what I was thinking :)
😢 Wanted to give it a go but says cannot ship to UK. Strange, have no issues from other EU countries.

4:24 I believe some of this solder joints needs to be resoldered
If you look carefully in the video you’ll see that I actually did :)

Yeah, I always found it funny how we need to be better at seeing the things we don't care about.
The title should read "$9", (nine dollar). Dollar sign goes to the *left* of the number.
Since you took the time to write that I’ll go right ahead and fix it..!
@@AndersNielsenAA Thank you.
