the solderings look good, and whats the chance of making bad solderings in the same place, on two such big boards🙄
which opamps are you using? sounds like it is oscillating with the servo cutoff frequency.... I used OPA134 with great results. I think Joachim mentioned once that they need to be FET inputs.....
I have now tried to change the 1uf bypass of the opamp to 220nf, and the offset is still wandering, but with only +/-50mv
I have been measuring the output of my running paradise and it wonders between +12mV and -5mV.... It sounds wonderfully as is.
I am kind of itchy too to try it for real, i might try it with caps on the output untill the problem is solved🙂
I am shure it amplifies, when i measure ac on the output, and at the same time touch the input, the measurement goes out of scale.
Does the output voltage fluctuate when you blow air on the input stage? It could be caused by the air around the transistors changing in temperature....
It actually have a lot of impact, to blow air onto the boards, on the input and even more so, on the mirrors, so i will experiment with thermic shielding/compensation. Thanks for the input🙂
Yes, there is some background work ongoing, to translate the assembly guide into german. Sorry I would have done it myself but I figured you would want to have your boards quickly 😀
It makes a lot of sense, given that a large number of boards actually goes to Germany.....
By the way, the first batch of boards + components is out the door, was picked up today. I think I can send the rest out this week, since next week is Electronica trade show here in Munich, and I will be busy.....

You dont need to apologise,
youve contributed more than enough to all of us !
Last weekend we talked a bit at Krefeld and there will
be some progress soon...
Hi.
I guess this question is for hesener.
Are the boards double or trible layer? Meaning, are there any hidden traces inside, that i can damage, if i will drill some holes, for cableties?
