Looks fantastic. Do you have a link for where to find that PCB by any chance?

Super tidy and excellent all around! Decal came out spotless spiffin', did you have a hard time getting it right or did it work first time and what was your process? I still haven't gotten around to use the filmless one...

Try increasing the Bias Trimpot to a 20k, that should bring the voltage down enough to center the sundial at 4.5V

Quote from: mjg on December 20, 2018, 09:20:43 PMThanks for the link. I used to buy stuff from RS in pre-Internet times but had forgotten about them. Free shipping is a godsend!
You're in NZ? Do you have RS Components there? That's who I use in Australia a lot, for last minute orders with free shipping. Sometimes you need to order a minimum of 10 resistors, etc.
Element 14 is OK, but shipping costs unless you spend $40 or something.
DIYGP (in the banner links above) is great, based in Melbourne, not sure how much the shipping would be to NZ.
