Brendan, it is great to have you back!!!
Thank you for cross-checking the BOM. I did heaps more work on it last night before ordering lots of stuff (already got the VT3 that you mentioned).
Luckily I did not order DD10,DD11 yet. I totally did not see that the part I picked was 6.2V. Neither was I expecting 6.2V for a part labelled 78L06 when all other 78L06s are 6V exactly.
The alternatives do not look good at RS, they have only 25 packs which are quite more expensive
Must do a bit more searching.
I will finish the BOM later tonight, only 5 components are missing now.
