Good point, looking back most of the circuit diagrams do show ceramic (or at least, symmetric) caps. It just so happens that the ATMEGA328 'pack' I picked up off Amazon had aluminiums for the power circuit. I'll see what I can find cheaply. Perhaps it's time to pick up a mixed box of ceramics...
Hi Klaus, that's great feedback thanks, especially as I was only really asking about the RF elements! I've got an Aluminium cap on each side of the LM7805 regulator, which is as per it's recommended circuit, but admittedly I've positioned them a little further away than ideal. Same again for the...
Hello BigBoss,
Thanks for getting back to me. After a bit of a crash course over the last few days I've refined the design - all very similar to what you say. But perhaps you could just have a look for my sanity!?
Basically, I changed out the cheapo modules for the STX/SRX 882 modules which...
Sorry if this looks similar to some other questions. I promise I've had a (quick) look around and can't find quite what I'm looking for.
Objective
I'm trying to design a remote control for a domestic system.
The prototype worked OK, using cheap and nasty 433 MHz OOK modules with straight...
