First power supply
I agree, I knew it would get quite toasty! The LM317 is rated for 125C, so surely I would need a heatsink at better than 5C/W for 5v at 1A (which is unlikely) EDIT: Junction to...

First power supply
Also, can I split Vout with a resistor divider, tapping the centre and buffering it with an open loop configured op amp, which will become the ground of the circuit? Won't this...

 Thanks, I've been trying to get my head around zener references, and I'm now pretty confident with the emitter follower set up, but perhaps I should go with the available...

First power supply
That is interesting... I guess that is basically the guts of an LM317. Could you expand on the zener voltage reference please. Is it also practical to include a simple voltage...

Wanted: low-end oscilloscope for use in repair and testing environmennt
 I own an Arduino Uno, although I want to get a new kit to enable me to more easily transfer programs made in atmel studio to a standalone micro.

Beginners Oscilloscope
If that is your opinion then by all means take it, but an analog can do whatever a digital can do (-storage of signals and advanced features that a 'noob' would not need). If you...

That's a nice idea, I have been looking at getting into that, perhaps I'll try and repair some gear for it (best way to get it). And good news on the scope front, a very kind guy...

Thanks to all of you guys, I guess I should have done a bit more research. I've sent some emails and hope to get a response.

Thank you both, although unfortunately I don't have a University within easy travelling distance, or any hacker groups in the vicinity. Thus, I must trouble the good folks ar AVR...
