You are right that this is just a part time hobby atm. But I have only made one prototype prior, and it does have a pressure sensor and an electric motor. I am currently working on my second one with a smaller motor, it will still go to high pressures, just takes longer. But the whole point is my design has many user settings, so you decide how much pressure you want. Also my latest version allows setting and viewing pressure in kPa, in-Hg, and cm-Hg. In Manual mode it will maintain the pressure you set until you turn it off. In Automatic mode it cycles. To be clear, in Manual mode it will pump to the set pressure and turn off. If there is leakage and after some time the pressure drops, the motor will run briefly to bring the pressure back up. If you want to, you could set it to low pressure and have it on all night. I will have to perform endurance tests to find out if this smaller motor holds up.
