hi,i designed a small 80x100mm pcb with an avr mcu Controlling 7 steppermotors. i would like to include a glavo control function, using 2 digipots, 6x4 opamp Chips, power stabilization and linear amps to power the 2 galvos, so around 10-15 main components.
who can do that pcb design for me? i already posted with another description and got numerous answers not leading to a final contract. i Need good answers, not: i can do it in 3 days. i prepared an email to send you all Details, so pls send me your address if you think you are competent choosing the right amplifier, knowing ie if mika insulation would be needed, or if a spike protection would disturb the process. the galvo travels several 1000 Points a second and Needs high accuracy.
hi, i am an electrical engineer. i have expertise in embedded system design.i can help you with this project. i have designed and developed a PCB which controls 16 stepper motors with RS485 communication. i can provide your further details on the work.
Please check my profile for my previous work experiences.
let me know if you are interested in the bid so we can discuss the details further. regards
Hello,
I am an embedded systems designer and would love to work on this project.
Kindly contact for further conversation and award of project.

Hi. I can do this for you. I have a lot of experience in pcb design. Even if I don't have any project done on freelancer, I've made around 40-50 pcb designs in Altium. Please give me more details about this project. I assume you have the schematics done and you need the pcb.
Hi there,
I have been working as an Electronics Engineer for various US, France and Australian based organizations. I have designed various products for companies located in the Silicon Valley USA. I am working as an Electronics Engineer in Australia at the moment.
I am doing Freelancing as a hobby. Not here just to earn money. I am sure I will be able to help you with your project.
Thanks and regards,

I am adept at PCB designing, I have sample snap shots of my previous work in altium designer , if you are interested in having a look at my previous work just send me an email if will send you the snap shots of pcbs which I already have designed.
Best Regards
Hi sir, I am farmiliar with the Altium designer, I think I can finish this layout very quickly and will find one supplier in china do one mockup for you after the layout(this mockup cost is not in the $60). Thanks!
Hi buddy, I would like to have the project Details as soon as possible. If you are interested i can send you my last work sample.
I am Electrical Engineer, have sound knowledge of PCB designing and specialty in designing custom foot pads. I work in Proteus, a software by Labcenter Electronics.

I have rich experience with precision mechanics using stepper motors driven through specific drivers and MCUs like AVR and C2000 (dedicated for motor control). How can you drive 7 stepper from AVR ? Do you have at least 7 dedicated timers/counters with compare units for that or do you use signal multiplexing. Current regulation of stepper motor is accomplished by ref. voltage through the driver chip. What do you measures with galvos ? heir arrow is moving according to current through the coil, so you need "something" to current converter. U-V converter is done on OpAmp easily. Could you clarify with you analog stuff on the board, as it's not clear from your description. What do these galvos show ? What do the gigipots sets ?
