I was banned and now I've only just rediscovered this thread.
Here's a picture of the whole thing, see this thread for more information.
I saw the banned under your name...but when I went to your profile (stalking you) It showed the last time you were on.....and both days said you were on earlier in the day. What did you get banned for....seeing your post #s I am thinking that banning you is probably not a good idea for the site...you are obviously an asset. Anyways...glad your back. Here's my questions so far.
1)How big should I make the board dim....yours in the picture looks like a good size.
2)Is this unit that you have in good working order..do you use it, or should it be tweeked?
3.) Should I add the C8 cap in my pcb design?
4.)According to the link you gave me...should I get the 15V-0-15V torroid rated to 2.67A Transformer...? I'm in U.S.
5.) R1 will use a 1/2 watt rating? R2-R6 1/8 watt rating?
6.) I should buy a 2.5kohm pot with a 1/2 watt rating? (R7)
7.) Rating of switch? SPST?
8.)Are these Caps for C1 and C2 good, or do you recommend better? Caps
I am not sure what the triangle is in the schematic...I want to say a rectifier...but I am not sure? According to the link you gave me. D1 should be 2.5A. But what does that mean.....and how do I go about making it.....or do I buy it?
Anything that you can tell me about the rectifier if that's what it is...would be very helpful....it don't look like much to know....but I'm not understanding it? I don't need to understand it....just tell me this diode rating goes here and this one goes there...blah blah...I'll figure it out when I learn to calculate and do the math...which by the way I am trying to learn everyday reading some good electronic books. My time is limited though...I work alot of hours taking care of the family.
K....as you can see, I have been waiting to hear from you for awhile. LOL
Sorry for all the newb questions......it's not laziness I assure you...I'm trying very hard to learn..and spend most my free time learning as much as I can.
By the way.....that last PCB I made that everyone helped me on....came out beautiful. I was very suprised at how well the soldering came out. The pads where so close together I thought for sure I would have a hard time with it. There probably isn't an 1/16 of an inch between some of them...specially around the IC's, yet none are touching ( I used a 10x magnifier to check ), solder is all the way around each lead, and they are nice and shiny. I noticed that in your PCB layout for the bi-polar supply that you used the rectangular pads instead of the round ones..so I will keep that in mind next time I make a board.
Thanks for all your help....and stay un-banned. Glad your Back.
