hi there, i already posted this Project separately but didnt get satisfying results. i work on the pcb to facilitate the Task:

i replaced the 1st digipot with a true 24bit dac. if you like another type, tell me pls.

as the digipot only likes 5v max, the voltage should behas been reduced to 5v on all opamps for the new function.

big opamp has to be chosen to drive the galvo

i use eagle, you can download it for free

i would like the device have its own ip and work wireless. the current atmel only allows a transmission of ca 1000 lines per second @30 bytes due to latency=unacceptable.

you can put out half of the opamps of the new function. push everything together, space is available.

fr4 - 2 layer as is.

the galvos Need a high accuracy, so you Need to check the design.

please: no comments: "i can do that!". i received 20 offers, and after all, nobody could give good answers.

so please write to me: what opamps would you choose, what dac (if you want to replace it), what galvo power opamp? you would Need to give me the Impression you know what you are talking about. i already lost three weeks with pretenders, that´s really enoying. i Need an analog specialist for the galvo function, and an mcu pro for the atmel chip replacement Task. please please dont let us waiste time with "i can do it" mails. send me good answers to Show me you really can do it. pcb layout attached.

can you also write the firmware? make 2 pcba samples? or even do the user interface? just curious;-)

newer file to Show space avail

please dont tell me your live and since when you do what. i dont want to read your Standard phrases copied and pasted. no "i can do it". why would you reply if you couldnt do it?!
update zip attached. just for showing that 2 layers are sufficient. there were "i can do it"-People demanding 6!!! layers for this layout.
if you have good answers, tell me. i am no layouter, i dont want to steal your ideas, but after 30 "i can do it" guys without results, finding the right freelancer costs much more time than expected.
