lol leave it to me to carry and keep a huge useless tv to get a part thats useless once removed :P
anyway, i guess that settles it for good - old tv -> junk
marking thread as solved
right, so i guess its pretty pointless to go through all the work and hazard to get an electron gun that i probably cant use anyway. i guess i'll just scrap the tv and do a search on how to actually make an electron gun in case i'm interested in the future
thanks for all the replies guys!
@klystron - just wanted to scavenge it for later, i have no intention of using it at the moment. when you say "risk" is it risk due to implosion or chemicals? i'm asking because implosion i can handle with precautions but if toxic chemicals from inside the screen become airborne, since i'm at...
i've got a real old tv that doesn't work according to the people who gave it to me. i've already opened the dinosaur up and most of its pretty musty in there, loads of dust and stuff. what i'm interested in is the electron gun (without the screen), the power supply and perhaps anything else that...
originally i did use both l-298 and 292 instead of this mess, but i scrapped them for some reason, i cant remember why, but i'm pretty sure there was some serious problem.
@tom66 - well, the enable input passes through a voltage divider, passing half its value to the + input, and the enable...
5V supply for the gates, +-12V for the opamp
should this be a problem? as far as i know, as long as the gates dont directly mingle with the outputs and stuff, there shouldn't be any issues, as the opamp will just compare its inputs. and the simulations didnt seem to present any issues with this...
yeah, thats what's bothering me - the op amps behave in that manner even without any of the rest of the circuit connected - even without ever being touched before, fresh from the box.
i guess that there could be lots of static in the room affecting their behaviour - for one, i've tried...
Ok, first of all hi all, i'm new here, nice to meet ya all, i guess
this is my circuit
i made it so i can control dc motors, just left/right and enable functionality. in simulations it works great. i know simulations aren't always correct and it does look a bit too bare even to me, but as...
