This is V2 of my pet project that previously ran using Arduino Uno.
The objectives are pretty straightforward:
Control power on/off wirelessly
User access control via RFID reader for safety reasons. Eg. Powering up a CNC machine
Time-based scheduling to reduce power wastage for machines idling
Power monitoring + logging
.
Version 2 — Spark powered!
Version 1 — Arduino Uno
.
It sure looks a little bulky but with self-designed PCB and removing the use of headers, this can probably fit well inside a standard power outlet used in Singapore!
If anyone interested in an open-source power outlet in general?
Do throw in some cool ideas you think might be awesome for this project!
I think your key feature might be the RFID safety lockout feature for industrial use. Perhaps you could use a mobile app to allow everyone who has an RFID “lockout” on the outlet to view who else has a lockout and the status of their work? That would be great for applications where there are multiple electricians to engineers working together repairing various parts of a machine or factory line.
One question. What power supply are you using to power the control board? I need a small supply as well for a project I’m working on.
Thanks for the info! Yeah the supply is a challenge as I will need to design one based on my packaging and wattage requirements. But yours looks pretty good for prototyping use as you mentioned.
If you make any progress on miniaturizing your own design and want to open source it, please let m know. I need a ~7 watts at 5VDC from 120VAC in the smallest package safely possible.
