I appreciate that postage to the UK seems to be an issue currently. Brexit sucks muchly.

Is there anyone getting PCB's made In the UK that wants to sell me a board or 2? Or failing that is there anyone that has Gerber files that they wouldn't mind sharing so I can get some of my own made? I don't seem to have issues getting stuff shipped from JLCPCB.

I appreciate this is someone else's work so I of course wouldn't mind paying for Gerber's etc.

Currently, I'm after a Compressor and a Big Muff which admittedly I could probably source in the UK if I really tried, but I do want more complex boards later.

Hello everyone.

I am looking to use this chip https://www.diodes.com/assets/Datasheets/AP3015_A.pdf as a DC-DC boost to take my battery voltage to around 9V to use in some of my pedal projects but its been a while since my highschool electronics classes (I'm 40 in 3 weeks )

The maths to get to Vout is:

Vout = 1.23V*(1+r1/R2)

Which should be simple enough but the "1.23V" is confusing me. I would have that that means 1.23*V but if thats the case I dont know what V is, and why would it use the * on the next multiplacation.

If would be great if one of you clever people could help

Thanks in advace.

It does thaks. The way im reading this the top is VC and the others connect to it?

I have also noticed 3 points on the schematic what say VC in an arrow



Do these want to be connected 9v?

Of course they are, thank you so much. Im not sure if i would have ever have got there.

I can't get some boards I need due to the international postasge embargo so am going to try my hand at making the boards myself here in the UK.

The boards I want to make (and have already bought all the parts for) are the cupcake https://www.madbeanpedals.com/projects/_folders/1590A/schematics/Cupcake2020.gif

I understand the schematic pretty will with the acception some what I think are pads which I have highlighted in red here.



Cany anyone tell me what these are please?

Thanks in advace.
