sorry gnash.....you would normally find em in old dot matrix printers, they were used to do the line feed and move the print head across tha page and are called steppers coz they moved the print head etc a step at a time

BK, they'd still be used in the newer printers / combos, to drive the print head / scanner head?

Way ahead of you guys... I have pulled apart some old scanners to other day... some nice DC steppers. Have to find a use for them now. Got about 6 or 7 of them. I want to turn them into linear actuators for my solar panel tracker.

I have some monsters here (210 oz) here for my half built CNC machine...

I just wanted to see a lagoon. Now I am SOOO confused.....

I must make a growbed intake switcher with no mechanical parts for we mortals who are as confounded by Les and his antics as I am.

Gimme six months I must bribe the hydro dynamics guys to throw a few hints my way.

Over the past couple of weeks (since moving SP to new system) I have been slowly heading towards HSM :shock: .

My fish have not been feeding, I had checked all the normal things:
PH 7.4 - new system so normal (had gradually acclimatised the fish before moving to higher PH)
ammonia 0, nitrites 0 and nitrates ~120 - so all okay there
temperature 26-28C - tick

Stood down from HSM :shock: today, the problem was the fish don't like seeing me towering over the tank - threw in a handful of pellets and closed the cover, minute later lifted the lid and all pellets gone :sunny: , put lettuce leaves in or Azolla - kinda disappeared (Les now happy little vegemite)

Gee this AP thing is fun :rr:

I don't know if others who have submerged tanks are experiencing the same?

They don't like you above them allright. I'm thinking it's instinctual - bird predators. Maybe if you disguised your beak....

Yeah thanks - believe you are right in bringing out their hiding instinct, thought starvation would breed it out of them, they obviously have more patience than me (oh no! - the "P" word :oops: )
