Anytime this newbie reads about less soldering and parts I think it is great.  I don't have a clue as to what these design decisions mean, but as long as it works and I can follow your assembly instructions I'm good.  Thanks.


Boy, I am with you!!  So did I understand you (RJ) to say that the PCB's for the current 4th LE coop will be this version 4?  These LE's will be my first so less stuff to solder is way OK with me. 

Thanks for the work RJ,
-Keith

Yes the Coop #4 will have the Version 4 PCB's

RJ,

Given the change, will you be adding the PCB and/or Heat Sink options to the coop?

Clearance sale on V3s?

Where are not suppost to change coops.

I will think about opening a short couple of day seperate coop for the pcb's and heatsink but I have a lot on my plate as it is.

I do not have any V3 PCB's left I had a one person I owed some that some went to and I just had someone buy the last ones.

Time to stop sitting on the sidelines and watching.   ;D

RJ, Thanks for addressing the problems responsibly as we all knew you would.

[RANT]
Peter, Thanks for pointing out this HUGE problem. I don't get it. You make a visit, grow a wild hair and it ends up costing me!! Since when is a spark across a gap on a moist night a matter of "personal safety"?  What are the odds? These questions are rhetorical.

JK,  but may I make a suggestion?  Visit more often or stop helping.  LOL

Any more suggestions for improvement need to be submitted in writing well before the 3rd CoOp of ther year is finished.
[/RANT]

I've made a command decision to test the odds and go with my original V3 pcb.

I know, I know,  I'm risking life and limb...... ooooooooo,.... scary!

What the heck. I live in Reno!

Leon



PS - Peter, if you know me at all, you won't take this in a bad way. I'm not that kind of guy. (Not attacking you, just having a bit of fun)

Leon, 

I know you and know you are joking.

But lets all keep from getting to a point where it is easy for people to take shots at each other under the claim of "It's a Joke" I saw what happened at another forum when the staff allow this. It runs people off. I know that you are joking but we need to be carefull or the next thing will be people who are not and bypassing rules under the thought they are.

The OP had a good point I acknowledged it and took action to improve the design. I did not remove the resistors to make it safer, I remove the resistor because when I was changing the design to make it better I saw that I could do away with them.

As far as using Ver 3 and prior PCB's, I will be using all of mine. I live in Florida (normal humidity when it's not raining is 80% - 90%) and have used the units for two years without one single failure or other issue. Even with water condensating on the pcbs I have not had an issue.

Considering Microchip thinks it's OK to hook the PIC's straight to the Triac without an opto at all I do not consider the two pins too close together a HUGE problem either if a builder does not bridge the gap but it could be improved and should, and in the process I found a better improvement that removes this issue and saves precious build time for our users also.

How much space is there on a triac leg between pads? 1mm same as we are talking about.

But what do they know? it's not like they are professionals or anything. 

The fact is all of us should be thankful for the input on the issue as it has led to improvements of the design. It was only the reaction afterwards that I questioned.

Lets not make the OP sorry he pointed it out or it will hurt the products in the furture because people will be afraid to post improvements.

Agreed. 

Thanks RJ  ;)

And Thankyou Peter. My intention was not to deter suggestions for improvement.

RJ,

first of all, thank you for making the changes you did. Not only did you look at what I suggested, you used the opportunity to make a change that seems to have improved the design no end.

extra details withheld pending a PM.

keep in mind when looking at this design that it is isolated from the user by use of a IR remote. so there are no low voltage sections of the board carrying data to other devices (pc's etc) .
