@Kasper Your kit will probably work just fine if you give it 15VDC instead of 15VAC. If it is a simple one using a bridge rectifier, then there's no question it will work. If your kit is a switching regulator of some kind, then it will probably work.

In either case, you need to make sure that your 15V supply can deliver at least as much current as the specified AC source for your kit.

Any ideas for making a point-to-point (dead bug) ground bus

@AdamUraynar Bus wire or a copper clad board to glue your dead bugs to.

prototyping board?

or a flat bits of copper board?

@AdamUraynar Copper clad board like you would use to make PCBs.

thanks

Branded Element14 / Farnell, hence 100% on topic

Got it at an electronics exhibition, but ... what is it?

why didn't you ask what it was?

just because it has an electronics brand on it doesn't mean it has to do with electronics

@AdamUraynar found it in the Farnell bag I received when I got home.

maybe it's for a smartphone

stick it into a car's inside vent

and it holds your phone

@AdamUraynar sounds reasonable for anything smaller than an 8cm, but I don't know about the weight.

Is it just plastic?
