I am working on a project to build peristaltic pumps and I have a need for someone to design a PCB to run the machine. It will have a small Step motor, like a NEMA 17. The basic functions will be On/Off, LCD Display, it will have a pneumatic foot switch, it needs to calculate the Rate being pumped and the Total volume based on the speed of the motor and display those numbers, control the speed of the motor, which will set the volume rate. Obviously, there are a number of details one would need to design this, but the PCB is the area I have no real knowledge to design. This would be the roadblock for my project, so I wanted to attack it first. I will be able to provide all of the specs needed. This isn't a rush issue. I am reverse engineering a pump, but the pumps I have have way too many functions on them and items that I do not need. I saw a YouTube video of a PCB a guy built using an Arduino board to control and display it. I cannot us an Arduino board in my machine, but it tells me this shouldn't be too difficult for someone who does this work, but I just don't know whom that would be. If I can get this done reasonably, we will build these to sell.
Again, simple functions:
On/Off switch (Power)
Drive a Stepper Motor and control the RPMs
Use a pneumatic switch and air bellows to operate the motor Off and On (like the ones in Spas)
Count RPMs
Calculate Dispensing Rate based on the RPMs
Count Total Volume dispensed
Display Rate being dispensed, and Total Volume dispensed.
Prime Button (runs the pump at the highest RPMs to prime the tubing)
Run a small cooling fan
Reset button or Clear the system for a new job.
I would also need some code written to run it. It may also, be good to have a way to fine tune or calibrate the machine in house, but not accessible to the customer, but that is a secondary option.
Will be powered by a Transformer producing 12 DCV from variable ACV input. (90 - 240 AVC). Standard shelf product. All of the components will be Std off the shelf items. These are the same type machines used in labs everywhere. Once I have a design, I'm sure I can get these made most anywhere, but a referral for the production of the PCBs would be helpful as well.
Thank you, Joe
