Wow, it was 2000 when i checked not so long ago!

Why is there so little going on with inkjet?
I was kinda hoping for more results.

I want to and have to make many more boards, but the oven is delaying me.  
I thought i could finish that before making more boards. I tried to design  
the control circuit today, but quite frankly i'm not happy about it. The  
first one or two components i needed i didn't have, and they cost about  
5eur (a temperature sensor like lm335 and a precision reference with low  
temperature drift). With things going like that i will be much better off  
buying an industrial controller for about 20eur.
It's only a handful of components i would need to buy, but probably still  
cost at least 20eur. And then the thing is neiter designed nor built, so  
i'm really leaning towards an industrial controller that would just need  
to be hooked up.

BTW i also tried taking the thermostat out of that old oven after shooing  
the mice away, but the deadband is like 60C and not adjustable. Useless.

Anyway, i guess i'll just use the clothes iron upside-down some more until  
i have a controller.
Got some propylene glycol at the chemicals shop recently, will report what  
it does if used like brake fluid.

Another thing, i noticed a slight height difference left/right of the head  
rails, so the head gap is not constant. This does not matter for most  
boards, but i bought a dial gauge anyway to adjust it precisely.
