It like as you have problem with MCP602 or around it.

You are right. MCP602 pin 1 was not connected.

Thanks

Being a geezer doing surface mount electronics is not by capability. I tried it and I don't have the skill to solder such small areas. My old eyeballs don't see that good.Do you have a non-surface mount version of the circuit board ?

You are not alone with the eye sight thing. Poor vision has taken a lot of the enjoyment out of electronics for me in recent years. I really have to be motivated to build something now.

I have used magnifying lenses of various type with some success but it is a hassle. I have a couple of very small closed circuit television cameras that I am going to try next. If I find a combination that works, I will post it.

I had a bit of a look at those atmega32 chips, it seems the smd's have 4 extra pins that the dip's dont
so maybe we will have to borrow hugo's magnifier
