Cheers Emyr.
took your advice on that dc to dc.
got a couple :)
for me to play around with, one for home etc.

so still gonna build mine, but, Ill have one to also play with now, working.
after modding it, I the heat shall be off so I can get on with designing 
my own too :)

going to start setting up an etching thing for circuit boards etc too.
but need to move stuff around to make room. read...lots....of........stuff.
frick.

anyone have advice on the old etching thing? quantities of ferous 
whateer it was? sourcing it etc.
ive got a uv lamp box with timer too, so dont know if I shoudl get the 
UV clad stuff  could be handy :)

I just used to had draw before with an etch resisit pen.
results were...umm....primitive :)

ok tata

oh ps, my aliexpress and bangood orders have been processed and sent!
wow.
hello china!
oh and my blown up uni pc has....healed! it now runs. random. I checked 
it late last night
Proteus and Ares on Windows and other programming things from uni days
and

SuSe Linux...being an arse and not booting correctly... no proper 
xwindows...when it does then boot........
screen flickers off every so many seconds.
never had any luck with that distro on that machine and have stuck to it.
maybe its ubuntu o clock.
but... I think it did play music out of the box.
I liked that :)
or maybe not standard repo downloads, cant remember.
ok
its attic o clock for me, jsut got the lights in, and extension lead. 
lets go have a look!
:)
