Hi,

I've got a few projects which I want to complete however my electronics knowledge is a little lacking. I did do systems and control (electronics) back in my school days (surprisingly I passed the gcse with a , but that's over 6 years ago.
Literally the only electronic things I've done since then has been the odd bit of soldering (I did manage to solder a RAMPS 1.4 board ) or replacing a resistor.

The projects I want to complete requiring creating circuits from scratch using logic gates, sensors, capacitors, etc and creating my pcb.

Can anyone recommend me some good site(s) with tutorials or software for circuit design?

Many thanks and apologies if this is the wrong forum or the completely wrong forums to be posting this.

Tutorials like these: [geda.seul.org] ?

Many people prefer the free, size limited version of Eagle, but gEDA and KiCad are on par, if not better, these days.

Generation 7 Electronics	Teacup Firmware	RepRap DIY

Thats the sort of thing I was looking for from the circuit design and pcb routing side of things.

I'm mostly looking for a good tutorial site with a reference (or even just a good reference site) section on general electronics so I can refresh my memory.
