I need a circuit board small enough to fit into a 1" tube that houses a piston. It needs to have a knob that will control the speed of the piston and a button to move the piston up, down, and OFF. The knob and button can be attached to the board with wires. They don't need to be inside the tube. The piston is battery operated, 6V - 12V.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you require a small controller board to be designed that would be able to drive a piston according to the stated specifications. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Block diagram of proposed solution (already done) 3. Schematic drafts based on proposed solution (already done) 4. Overview and discussion of schematic drafts 5. Component library creation 5.1 Schematic symbol library creation 5.2 Footprint library creation 6. Schematic drawing 7. Layout design 7.1 Components placement and arrangement 7.2 Review of proposed layout design arrangement 7.3 Components routing 7.4 Review of final layout design 8. Design rule check 9. Verification and validation 10. Production files (GERBER, NC DRILL, STEP, BOM, ASM, PICK & PLACE, SCH, 2D mechanical drawing) Your project will be carried out on Altium Designer. Job will be completed before delivery term. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

Hi. Interesting project. I congratulate you on your initiative. To make your circuit is possible to use a small microcontroller (PIC12F675) that has 2 digital inputs for buttons (to handle up and down), an analog input for knob and an output with PWM to control the speed of the piston. Other components would be needed but I'm sure that will adapt to the size you need. I recently did a circuit very similar for operating a linear actuator for an industrial printer for raising and lowering a print head (you can check my last completed work). The only question I have is on the piston type or model you want to use. Is it a magnetic piston? or is a linear actuator?. Please I would like to know more detail about that. Thanks regards Pardo Darwin
