Parker
- Garage Door opener hacking
- Converting my normal style garage door opener to a “jackshaft” style opener
- Reversing the direction of the A/C single phase motor?
- Split phase motors
- One phase is shifted with a large capacitor by ~90 degrees
- In my application I just had to reverse the wires and the end stop wires
- PyInstaller
- Can take your python scripts and make it into a self contained application
- Useful for non technical inclined people on your team
- Cross Platform!
- GUIs
- Tkinter seems to work well in Win10 and Ubuntu 20 LTS

- High voltage low current measurement
- Tony_W Recommended the ACS37002
- Hall effect sensor that can be ground referenced in very high voltage applications
- 0.85m ohm conductor resistance
- 4.8kV RMS isolation voltage
- VCC of up to 6.5V
- -50 to 50A sensing range
- Gain selection of 30mv/A to 60mV/A
- In my situation I would want to monitor 0.1mA or 100uA. With a gain of 60mV/A that would be 60uV/mA so 0.1mA would be 6uV….. This may still not be the best solution because I would likely need a ton of gain and have to correct for any offsets.
- Possibly to a tro prong approach - Measure voltage across known resistances in the circuit
- Tony_W Recommended the ACS37002
- Getting transformers manufactured for your product
- What do you need to know?
- How do you get started?
- What are the specifications
- Mains transformers
- SMPS and flyback style “yellow tape” Transformers.
