I’ve never used KiCad… can I create a PCB without having to create a schematic? Can I just design a board with holes where I want them?

Datacenter rush will create ‘tsunami’ of discarded electronics, report says
Global push will triple toxic e-waste annually in 25 years, filling enough shipping containers to circle globe six times

Got myself a selection of small resistors for making dummy load for a PSU, and a few more random ones - don't see the silver band much!
(I've got to say Rapid electronics in the UK was - ordered just before 4pm yesterday,delivered before 2pm today on standard delivery).
#electronics

A selection of low values resistors, e.g. a 1 ohm brass covered, a 0.22ohm normal shaped, and some of the 4.7ohm white blocks
A couple of very low resistance resistors, a 0.82ohm and a 0.22ohm; with their nice silver band for the multiplier

RE: mastodon.social/@tubetime/1172
This is an excellent book. My copy arrived a few days ago and I'm several chapters in.
It's a great introduction to

Hunting through the 'wirewound resistor' box to see what low value ones I have.
#electronics

A big untidy pile of high current/wirewound resistors in all shapes, sizes and ages. Some are the ones with the brass surrounds, most are enamel covered, there are a few of the white clay like ones. Many have hand written markings.

suppose i have one of these small ESP32 thingies which drives a peripherial - all neatly on a board. Is there some generic component - that comes with a usb and battery connector - that i can solder onto the power pins of the board so that it becomes portable and rechargable and preferably i can choose what size of LiPo battery i attach?
yes, i'm lazy, don't want to design&build a specific solution.
